mmlu | Question:
While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted--being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer! About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens. Late last year, the engineer presented a video of his first prototype that begins by creating a single slice of dough that is cooked and printed at the same time. Then comes the tomato "sauce" -- a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn't show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds. While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That's because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not. Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars! Why does the author mention the things that astronauts in space cannot do?
Choices:
A. To ask us not to take common things for granted.
B. To show they live a difficult life there.
C. To show their life is boring in space.
D. To introduce the topic of the text. | D |
mmlu | Question:
Who do you think breaks the law in our society? If you believe that only tough guys commit crimes, you may have to think again. Unlike in the movies, we can't divide the world into bad guys and model citizens. _ In the same way that diseases range from the common cold to fatal forms of cancer, crimes vary in degree. For example, smoking in an elevator will inconvenience people, but much less than threatening them with a gun. In addition to breaking the law themselves, people tolerate various levels of crime. Why can we tolerate some crimes? It may be that, by seeing others do something, we accept it more easily. For instance, most people will find it easier to speed on a highway when everybody else is driving over the speed limit. When people celebrate a sports championship, if they see someone breaking store windows, they might start breaking windows themselves or even steal from the store. So the people around us influence how much law-breaking we can tolerate. We must also wonder whether seeing violence on television or reading about it in the newspapers every day makes us tolerate crime more than we should. We become used to seeing blood on the news on television, or in full color in newspapers and magazines. Because we see thousands of dead people on TV, maybe we just try to ignore the situation behind the violence. If so many citizens tolerate violence and crime, or even commit crimes themselves, it may simply be because of the human mind. Our minds may not care about specific laws. Instead, our minds may have a system of values that usually prevents us from hurting other people to improve our own lives. Yet, when it comes to respecting the rights of a mass of anonymous individuals, we might not be so responsible. While most people would not steal a wallet containing $50, they may not mind cheating on taxes, because cheating on taxes does not hurt any one person. It hurts society, but "society" remains an abstract idea that is not as real as a neighbor or a friend's friend. When we realize that so many people have misunderstandings of law-breaking, it is not surprising that so many people tolerate crimes, or even break laws, including me. But how could we improve the level of honesty in our society? Would strict laws help make our society better? Probably not. Honesty will have to come from social pressure: in the family, at school, on the job, each and every one of us can encourage honesty by showing which behavior is unacceptable. And teaching respect should become everyone's responsibility. What does the author think of the people who cheat on taxes?
Choices:
A. They take no notice of the human mind.
B. They break the laws unaccepted in their minds.
C. They aren't concerned about some particular laws.
D. They hurt other people to improve their own lives. | C |

A. Bow-Lingual's inventors
B. dog barks and their different emotions
C. talking dogs

Community theatre is a theatre that is run by a local district with the efforts of volunteers. They offer many different kinds of productions, such as musical theatre, dance theatre and children's theatre. Usually, performers are amateurs who receive no pay, but at other times professionals get involved, and they are paid. Community theatres of today are a little different from the old "little theatres", as most simply run by colleges and their theatre Community theatres are a great way to get involved with local actors. Now, most theatres that put on shows that will entertain or benefit the community. In the 1880s, "little theatre'' was started in Europe so that poor people could see theatrical productions without having to travel far or pay a lot. In 1910, this idea traveled to the United States. In the early years, community theatres were even funded by the government, but when shows became too political, government funding was stopped. Community theatres of today are a little different from the old "little theatres", as mist simply want to infuse little culture into the lives of the local citizens. In many cases, these theatres are run by colleges and their theatre departments. These productions are often free of charge, or charge very little money to pay for costumes and other incidental expenses. Many also encourage the participation of children and other young people to let them develop theatrical skills, as well as to keep them busy so that they do not do choose to get into trouble. Additionally, for those who desire strongly to become professional actors and to one day get a chance to act in a national theatre production, it is an exciting place to learn and develop theatrical skills. From the passage we know that community theatres can _ .

(NEW YORK)---Scientists have discovered small signs of awareness in some vegetative brain injury patients and have even communicated with one of them---findings that are beneficial to how to assess and care for such people. The new research suggests that standard tests may ignore patients who have some consciousness, and that someday some kind of communication may be possible. In the strongest example, a 29-year-old patient was able to answer yes-or-no questions by picturing specific scenes the doctors asked him to imagine. "We were stunned when this happened," said one study author, Martin Monti of the Brain Sciences Unit in Cambridge. "I find it really amazing. This was a patient who was believed to be vegetative for five years." Ever since a research paper four years ago described obvious signs of awareness in a vegetative patient, families of patients have been demanding brain scans, said Dr. James Bernat, a spokesman for the American Academy for Neurology. But experts said more study is needed before the specialized brain scans could be used in medical treatment. "It's still a research tool," Bernat said. Experts also pointed out that only a few tested patients showed evidence of awareness. And they said it is not clear what degree of consciousness and mental abilities the signs imply. They also noted that the positive signals appeared only in people with traumatic brain injury---not in patients whose brains had been lacking in oxygen, as can happen when the heart stops. The new study used brain scanning called functional MRI, for 23 patients in a vegetative state and 31 that are minimally conscious. Patients are said to be in a vegetative state if they are tested and found unable to do such things as move on command or follow a moving object with their eyes. Minimally conscious patients show signs of awareness, but they are minimal and discontinuous. The passage mainly deals with _ .
Choices:
A. how to recognize a vegetative patient
B. the significance of a new scientific finding
C. how family members look after a vegetative patient
D. the latest findings on awareness in some vegetative patients | D |
mmlu | Question:
This winter, the air quality over the north China plain was so bad that it was actually off the standard scale. The air pollution reached levels that the World Health Organization describes as dangerous. On Thursday, heavy smog blanketed most of northern and eastern China again. It is reasonable to ask why the air pollution is so bad this winter. Weather conditions and topographic factors have been given as reasons, but, although contributing factors, these are not to blame. The worsening air pollution is linked to an energy mix that relies heavily on coal and to motor vehicle emissions . But despite the astonishing growth of motor vehicles in our cities, it is the burning of coal that is the biggest cause of air pollution. More than half of the country's power plants are located in the eastern region and China's coal consumption has more than doubled in the past decade, reaching 3.8 billion tons last year, accounting for almost half the world's total coal consumption. And with coal occupying nearly 70 percent of the country's primary energy consumption, it has become critical to reduce the use of coal if we are to solve the nation's overall air pollution problem. In the face of the poisonous air recently, one citizen said, "we have nothing but hot air to purify the skies". In fact, the government plans to have 350 billion yuan ($55.67 billion) investment in improving coal-fired facilities and limiting the use of yellow-label cars that do not meet the Euro I emissions standard and so on. However, it would be far more effective to reduce emissions at the source, which means that the biggest challenge currently facing government departments is saying "no" to the country's air polluting offenders. According to the Joint Prevention and Control Plan on Air Pollution in Key Regions released recently by the State Council, the amount of coal the nation consumes is set to rise by 30 percent during the period of the 12th Five-Year Plan. This is not going to let anyone breathe easier. This highlights a key problem when it comes to environmental issues in this country - economic development comes first. The fundamental cause of the worsening air pollution is the idea of economic growth at any cost, which has resulted in ever-worsening pollution. And the priority given to economic growth presents another problem, namely the failure of existing environmental protection policies and regulations to control pollution. For instance, the current weak regulations covering emissions would suggest there has been a significant reduction in emissions when clearly this is not the case. Also those enterprises found breaking the regulations are still far lower than the cost of treating the pollution they produce. This means even if many large-scale enterprises with lagging production capacity fail to meet the requirements for environmental protection, the environmental protection department is incapable of shutting these enterprises down or forcing their relocation. [: _ Z _ X _ X _ K] Dealing with air pollution requires taking action at the local level to reduce vehicle emissions and at the regional level to reduce industrial emissions. But it also requires giving more priority to environmental issues in policymaking. Our hope is that the environmental protection department will be truly capable of saying "no" to pollution, and it will raise standards and effectively enforce them, and that governments at all levels will prioritize quality of life not just economic growth. Why is it a big challenge for the government to say "no" to the air polluting offenders in China?
Choices:
A. Because enterprises are encouraged to develop economy at the cost of the environment.
B. Because much emphasis has been laid on economic growth regardless of the cost.
C. Because it's impossible to relocate the enterprises for lack of money.
D. Because the production capacity of enterprises falls behind the required speed. | B |

A powerful earthquake struck the northeastern coast of Japan at two forty-six p.m. local time on March eleventh.2011. Japan's Meteorological Agency released its first tsunami warnings just three minutes later. The country has one of the best earthquake early warning systems in the world. There are more than four thousand Seismic Intensity Meters in place throughout Japan to measure earthquake activity. These meters provide information within two minutes of an earthquake happening. Information about the strength and the center of the earthquake can be learned within three minutes. There are also concrete sea walls around much of the Japanese coastline. But these measures proved no match for the powerful earthquake and tsunami. Costas Synolakis ,a tsunami expert at the University of Southern California in Los Angeles said,"Japan is one of those most well-prepared countries on earth in terms of tsunami warning. They had a warning. I think what went wrong is that they had not expected the size of this event." He says there are two reasons for this. Japan has not had any event anywhere near as big as this one in the last one hundred fifty years. And scientists had not expected such a large earthquake happening off the coast of Japan. The nine point zero magnitude earthquake was the fourth most powerful earthquake ever recorded worldwide. It was also the worst earthquake ever to hit Japan. The tsunami waves that followed were reported to have reached as high as thirteen meters in some areas. Costas Synolakis says Japan's concrete sea walls were not built to handle such high waves. Experts say early warning systems will continue to be limited by these facts until earthquakes and tsunamis can be predicted Which of the following statements NOT true ?
Choices:
A. A terrible earthquake hit the northeastern coast of Japan
B. It was also the worst earthquake in Japan
C. The 9.0 earthquake was the fourth most powerful earthquake ever recorded in Japan
D. Japan's concrete sea walls was unable to handle such high waves. | C |

Just weeks after a special memorial voyage to mark the 100th anniversary of the sinking of the Titanic, an Australian billionaire has announced plans to build an exact replica of the Titanic, which is just as similar to the original one as possible. The Titanic replica will make its first voyage from Southampton, England to New York in 2016. The Titanic is a famous ship that sank in 1912. The attractive story of the ocean liner has made millions of people interested in it around the world. It was believed to be an unsinkable ship but it hit an iceberg and sank on its first voyage. More than 1,500 people died in the sinking of the Titanic, which at the time was the world's largest and most luxurious ocean liner. When fully built, the Titanic II will be 270 meters (886 feet) long and capable of holding 1,680 passengers. Unlike the original Titanic which was powered by coal-fired boiler and steam engines, the Titanic II will have modern diesel and electric engines. Also unlike the first Titanic, the Titanic II will have more than enough lifeboats to accommodate everyone on board if something should go wrong. When asked whether the new replica would sink, Mr. Palmer replied: "Of course it will sink if you put a hole in it. He also added "It will be designed as a modern ship with all the technology to ensure that doesn't happen." When Mr. Palmer was asked if he expected hisTitanic to be successful, he simply said: "At my age, you don't really worry so much about whether you'll make money or lose money on something, but I believe that it is worth building it." Why is the Titanic replica being built?
Choices:
A. To make a voyage from Southampton, England to New York.
B. To mark the 100th anniversary of the sinking of the Titanic.
C. To realize Mr. Palmer's dream of constructing a luxuriousocean liner.

Don't go to Kauai. Go to any of the other Hawaiian Islands--Maui, Lanai, the Big Island-- but leave Kauai for us. The weather on Kauai is so unpredictable that sometimes it rains all day--in fact, it's the second-wettest spot on the earth. Yes, there are giant double rainbows all the time, and the sunlight through the clouds is magical. But if you are not interested in these, go somewhere else. You just can't control the nature on Kauai, and who wants to surrender to the nature when you could be at a fine hotel, lying in a comfortable chair next to a swimming pool, with food served upon request? So what if Kauai produces surf champions the wayprefix = st1 /Texasproduces cowboys? Most of its 300 white-sand beaches are unmarked. Unless you connect with the local people, the hidden spots are hard to find. While Hanalei is the most beautiful town you've ever dreamed of, you can forget about discos and clubs. Worse, it doesn't have one single four-star restaurant. What it does have is the original drive-through places where you pass by a rambutan tree, and pick a piece of fruit. Shopping in Kauai? Forget it--unless you are interested in shell necklaces and beautifully carved wood bowls. Kauai is not about pampering. It's about going natural and finding the nature within you. It's a do-it-yourself place that offers walking along the coast, diving and swimming in the Pacific Ocean, and lying on the beach. Don't go to Kauai unless you have a lot of time, because there's only one road, which can be slightly dull. It winds through the beautiful scenery of waterfalls, rivers flowing into the ocean, and taro fields. You have no choice but to look at everything, because the speed limit is 35 m.p.h. If you're not interested in color1, don't bother with Kauai, because that's what you get--red roads, blue oceans, and a hundred different shades of green. It's like diving on land. Many people on Kauai believe that this is Lemuria--a lost island in the Atlantic. Can you imagine? Those Hawaiians, surfers, New Agers, and people who love nature and beauty and want a different quality of life--what do they know, anyway? Forget about it--you're not going to like it. Go somewhere else. Leave Kauai for us. It can be learned from the text that _ .

If you live in the U.S., you're probably used to throwing banana peel into the trash. But people in other countries, including India, have been taking advantages of their nutritional benefits for many years. While the flesh of a banana is soft and sweet, the skin is thick, hard and slightly bitter. To eat the peel, you can fry, bake, or boil it for at least 10 minutes. Also, the riper bananas get, the thinner and sweeter banana peel will become. That's because of a natural plant hormone called ethylene that fruits release as they ripen. Ethylene interacts with the sugars and fiber in the banana skin, changing complex sugars into simple sugars and breaking down pectin, a form of fiber in bananas that keeps them stiff. That's why the older your banana is, the flimsier it feels. The sweet flesh of a medium-sized banana contains great percentages of your daily recommended intake of various nutrients, such as: *12% of your daily fiber, which helps with digestion and may help lower your risk of diabetes *17% of your vitamin C, which is important for your immune system as well as your growth *20% of your vitamin B6, which aids the body's ability to turn food into energy *12% of your potassium, which helps with the development of cells, tissues, and organs throughout the body If you eat the skin along with the flesh, you will get an even bigger increase in these same nutrients. Eating the peel is not only good for your body but also better for the earth. The average American ate 11.4 pounds of bananas in 2014. Since a medium-sized banana weighs about 0.3 pounds, that equates to about 38 bananas per person, or about 12 billion for the whole of the U.S. And since most of us throw away the peel, that also means a lot of organic waste. We can learn from the text that in the U.S. people _ .
Choices:
A. like eating bananas
B. waste a lot of food every year
C. don't make good use of banana peel
D. know little about the value of the flesh of bananas | C |
mmlu | Question:
People all over the world today are beginning to hear and learn more and more about the problem of pollution.Pollution is caused either by man's release of completely new artificial substances into the environment,or by releasing greatly increased amounts of a natural substance,such as oil from oil tankers into the sea. The whole industrial process which makes many of the goods and machines we need and use in our daily lives,is bound to create a number of waste products which upset the environmental balance,or the ecological balance as is also known.Many of these waste products can be prevented or disposed of.But while more and more new and complex goods are produced,there will be new,dangerous waste to be disposed of,for example,the waste products from nuclear power stations.Many people,therefore,see pollution as only part of a larger and more complex problem,that is,the whole process of industrial production and consumption of goods.Others again see the problem mainly in connection with agriculture,where new methods are helping farmers grow more and more on their land to feed our ever-increasing population.However,the land itself is gradually becoming worn out as it is being used,in some cases,too heavily,and artificial fertilizers can not restore the balance. Whatever its underlying reasons are,there is no doubt that much of the pollution caused could be controlled if only companies,individuals and governments would make more efforts.In the home there is an obvious need to control litter and waste.Food comes wrapped up three or four times in packages that all have to be disposed of;drinks are increasingly sold in bottles or tins which can not be reused.This not only causes a litter problem,but also is a great waste of resources,in terms of glass,metals and paper.Advertising has helped this process by persuading many of us not only to buy things we neither want nor need,but also to throw away much of what we do buy.Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying,excessive consumption and careless disposal of the products we use in our daily lives. In the writer's view,the more new goods, .

Two years ago, the Funk family of suburban Chicago adopted a Chinese baby girl who had been abandoned on a sidewalk near a Yangzhou textile factory. Last year and halfway across the United States, the Ramirez family of suburban Miami adopted a girl who had been abandoned a week later on the same spot. Both families named their daughters Mia. It turns out, a first name and Chinese heritage aren't the only things the three-year-olds have in common. The girls' mothers--Holly Funk and Diana Ramirez--met on a website for parents who had gone through international adoptions. After a flurry of e-mails comparing photographs and biographical details, DNA testing proved the families' suspicions: The girls are probably fraternal twins. "I was in shock," said Ramirez, who lives with her husband Carlos in Pembroke Pines, Florida. "Well, now this is for real." The Internet and Web groups revolving around international orphanages are increasingly being used to link adopted children with biological kin . The site that the Funks and Ramirezes used has a membership of 137 people, with 15 sets of twins and seven sets of siblings whose relationships have been confirmed. At a reunion on Friday at Chicago's O'Hare International Airport, Mia Diamond Funk Mia Hanying Ramirez shyly surveyed each other, then reached for each other's hand. DNA tests established an 85 percent probability that the girls are at least half sisters. Scientists did not have a biological parent to test and reach a greater certainty, but given their ages and physical similarities, experts say it is likely they are fraternal twins. Douglas and Holly Funk hope to take Mia to Miami in October. Both sets of parents say they are committed to staying in touch and often let the twins talk to each other on the phone. Why did the girls' mothers meet on the Internet?

Peter, a high school student, was pretty busy with school, and he was on the soccer team. High school was hard, because everyone wanted to have nice clothes, hang out, drive cars, and all these cost money. Peter's father was the sort of guy that believed you had to earn whatever you got, so he wasn't just about to hand over lots of money for Peter to use to have fun. So, he had to get a job. During his freshman year summer vacation, his classmate got him a job working on a hay farm. He threw hay up into wagons as the tractor drove around fields, and then they stacked it in the hot barn. It was a hot, lowpaying job. He once worked a few nights a week at a grocery store. He put things on the shelf. It was a lot of lifting and carrying, and his arms were strong from this and the previous job. It was dull and didn't pay much. He took some time off when soccer got serious, but the following summer he tried working at a lumber yard. It was hot outside, but he got a lot of exercise lifting and carrying things like boards and drywall. He also learned a lot about building supplies. It still didn't pay well. From there, he spent a year doing some tutoring for a friend of the family, but that was piecemeal. His first real job came the last year at school, when he fixed registers and worked on computers at a big box store. It was his favorite job yet, but it still didn't pay well. What Peter realized with all of these jobs was that he needed a better paying job! The only way to get that was to get trained or educated. He could go to school and get a 2year degree in an office or technical position. His other choices were going to a 4year college or joining the army. He wasn't sure what he was going to do yet, but he knew he had to do something. Jobs were a lot of work, money was hard to earn, but he liked staying busy and being able to buy things. Peter wanted the most out of life, and that meant education. We can learn from the text that _ .

A. Peter knew what to do for his future
B. Peter's father didn't care about him
C. it was very hard for Peter to make his choices
D. Peter was determined to do whatever he liked | A |
mmlu | Question:
In the course of working my way through school, I took many jobs I would rather forget. But none of these jobs was as terrible as my job in an apple plant . The work was hard; the pay was poor; and, most of all, the working conditions were terrible. First of all, the job made huge demands on my strength. For ten hours a night, I took boxes that rolled down a metal track and piled them onto a truck. Each box contained twelve heavy bottles of apple juice. I once figured out that I was lifting an average of twelve tons of apple juice every night. I would not have minded the difficulty of the work so much if the pay had not been so poor. I was paid the lowest wage of that time--two dollars an hour. Because of the low pay, I felt eager to get as much as possible. I usually worked twelve hours a night but did not take home much more than $ 100 a week. But even more than the low pay, what made me unhappy were the working conditions. During work I was limited to two ten-minute breaks and an unpaid half hour for lunch. Most of my time was spent outside loading trucks with those heavy boxes in near-zero-degree temperatures. The steel floors of the trucks were like ice, which made my feet feel like stone. And after the production line shut down at night and most people left, I had to spend two hours alone cleaning the floor. I stayed on the job for five months, all the while hating the difficulty of the work, the poor money, and the conditions under which I worked. By the time I left, I was determined never to go back there again. How is the text organized?

mmlu | Question:
Once Effendi had a joke with the Prime Minister . He said that the Minister would die the next day. The next day, the Minister fell to the ground from the horse and really died. When the king learned this, he got angry and sent his men to catch Effendi at once. When Effendi was brought to him, the king shouted angrily, "Effendi, since you knew when my Minister would die, you must know the date of your own death. Say it out, or you'll die today." Effendi looked at the king for a while. Then he answered, "But how can I know? I'll die two days earlier than you." The king was afraid that if he killed Effendi, he himself would die after that.

If your family is like many in the United States, keeping a lot of bottled water at home, it's easy to get a cold one right out of the fridge on your way to a soccer game or activity, right? But all those plastic bottles use a lot of fossil fuels and pollute the environment. In fact, Americans buy more bottled water than any other nation in the world, and add 29 billion water bottles a year to the problem. In order to make all these bottles, manufacturers use 17 million barrels of crude oil . That's enough oil to keep a million cars going for twelve months. So why don't more people drink water straight from the kitchen faucet? Some people drink bottled water because they think it is better for them than water out of the tap, but that's not true. In the US, local governments make sure water from the faucet is safe. People love the convenience of bottled water. But maybe if they realized the problems it causes, they would try drinking from a glass at home or carrying water in a refillable steel container instead of plastic. Unfortunately, for every six water bottles we use, only one makes it to the recycling bin. The rest are sent to landfills. Or, even worse, they end up as trash on the land and in rivers, lakes and the ocean. Plastic bottles take many hundreds of years to break down. Water is good for you, so keep drinking it. But think about how often you use water bottles, and see if you can make a change. And yes, you can make a difference. Remember this: recycling one plastic bottle can save enough energy to power a 60-watt light bulb for six hours. No matter who you are, you can do something for the environment. Join us and protect the environment. What's the best title for this passage?
Choices:
A. Drinking water: bottled or from the tap?
B. How to save more energy?
C. Why is it good to drink water out of the tap?
D. Stop drinking bottled water from now on. | A |
mmlu | Question:
" Drink your milk.It is good for you! " You've probably heard that many times, and it is true.Milk contains calcium, which is a necessary nutrient for keeping bones and teeth healthy and strong.The US government even requires milk as part of the National School: Lunch Program, saying that students should drink one cup of fat - free milk at each meal. Last Thursday, however, a group of doctors asked the government to remove the lunch program.The Physical Committee for Responsible Medicine says, "Milk is high in sugar, high in fat and high in animal? protein," all of which have negative effects on health.The PCRM says there were better and healthier ways to get calcium such as eating beans, broccoli, cereals and tofu.Orange juice and soymilk that have calcium added to them also supply the nutrient."One of the only reasons people talk about dairy, or promote it at all, is because it is going to help build strong hones." says Dr.Neal Barnard, president of the PCRM.But milk may not be the best way to get calcium your body needs. Of course, calcium is important for health bones and teeth, but there are other things that affect your bone strength, such as genes, how much vitamin D you take in and getting an hour' s worth of exercise every day. Some nutritionists disagree with the idea that milk isn' t important.Keri Gans, a dietitian, says, " I think it is irresponsible to take this beverage that children enjoy, especially among those who are unable to meet their nutrient needs for the day, and remove it from lunch time." The US government is studying the request of the PCRM, but a decision may be a one way to take off.Meanwhile, Marion Nestle, a professor at New York University, put it best: " Milk demonstrably has nutrients.Other foods have the same nutrients.It' s just a food.Like other foods, too much might be a problem." Which of the following opinions does the PCRM support?
Choices:
A. Milk is harmful to students' health.
B. Students should drink more milk each day.
C. Orange juice is higher in calcium than milk.
D. Milk is the best way to get calcium. | A |

Think back to a time in your life when you tried something new. When I was a teenager I volunteered to pass out water at a local race. I was so excited to see all the different runners who passed by and quickly took a cup of water. Some ran past, some walked past and a few wheeled past.[:ZXXK] I saw so many types of people doing it. I thought maybe I could do it too! The next year I decided to run for the race, but I had little running practice. I just wanted to finish. On the day of the race, it was terribly hot. After running for about 5 miles, I was thinking, "I must be crazy. Why did I do this? What was I thinking?" And at one moment, I said to myself, "I am never doing this again!" That first 10 km race was quite an experience. I jogged, I walked, I jogged and walked. At times, I didn't know if I could finish. Near the end, a 70-year-old man ran past me, very fast, and I felt a little embarrassed that I was more than 50 years younger than he and I couldn't even keep up with him. But then I realized something. He was running his race and I was running mine. How often in life do we compare ourselves to others when we really shouldn't? I decided that I would not give up on running races,and that one day I would be one of those 70yearolds who were still running. As I crossed the finishing line, I was proud of myself. I didn't regret having such an experience. What did the writer do at a local race as a volunteer?

A. He helped old runners.
B. He passed out water to the runners.
C. He cheered for the runners.

mmlu | Question:
In the past, if a person wanted to see the national treasures of a country, one had to go there in person. Therefore, very few people were able to enjoy some of history's most important and interesting artifacts . This has changed with an increase in the number of traveling museum exhibitions. King Tutankhamen Artifacts A traveling exhibition of artifacts from the tomb of King Tutankhamen, popularly known as "King Tut", toured the United States from November 1976 to April 1979. The 55 objects were shown in six cities and were seen by around eight million museum-goers. The second touring exhibit was started in 2007, this time with 130 artifacts and stops in London and three different American cities. However some objects, like the king's golden face mask, are too valuable or too delicate to be transported long distances, so "replicas" (exact copies of something) are on show. Japanese Color Woodblock Prints The Art Museum at University of Virginia, in Charlottesville, Virginia, has an extraordinary collection of Japanese color woodblock prints . These prints document the period from about 1850 to 1900, a time when Japan was opening itself to Western influences. Before this point, Japan was a closed society that had little communication with the world outside of its borders. These works of art beautifully show the feeling of change and the trend toward modernization. The museum has put together a traveling exhibition of 60 of these prints, which can be borrowed and exhibited worldwide for periods of eight weeks or more. Face-to-face with "Lucy" One of the world's most famous archaeological finds in history are the 3.2 million-year-old bones of a 106-centimeter-tall female found in the Ethiopian desert in 1974. Lucy, a name given to her by the discovery team, is a "hominid", or a creature that scientists believe is the earliest ancestor of modern human beings. Rarely is an artifact this valuable allowed to travel widely, but Lucy has been taken to several museums in the U.S. while a detailed replica remains at the Ethiopian Natural History Museum. What do the Japanese woodblock prints show about the society from 1850 to 1900?
Choices:
A. Japan had little communication with other countries.
B. The whole country refused changes in the society.
C. Japan was opening itself up to Western ideas.
D. Japan achieved modernization. | C |

A great deal of attention should be paid to the choosing of a vacation destination. Here are four of the must-see attractions in Alberta, Canada. The Banff Gondola The entire Banff area is a destination filled with wonderful things to do, but one of the best things to do is ride the Banff Gondola . This gondola takes visitors high above the beautiful scenery of the area, giving them wonderful views and photographic opportunities. The ride is also thrilling with a steady altitude change as the vehicle gets higher and higher. The Calgary Stampede The Calgary Stampede is one of the best events in Alberta. It has been taking place for a very long time. The entire event is worth the effort in going, everything from the opening parades and celebrations to the later events and competitions. Johnston Canyon For those wanting to experience some of the beautiful natural surroundings that are offered in Alberta, a visit to Johnston Canyon is a must. In this canyon, there are a number of impressive waterfalls available. They are very easy to approach. Miette hot springs The number one attraction there at the Miette Hot Springs is the hot springs themselves. The pools are filled with water straight from the springs and are very clean.

The way we get about has a deep influence on the way we live-affecting where we set up home, work and holiday. So what changes might come in the way we get around? What big ideas are out there, and do they have any chance of coming true? Personal Air Travel The idea: flying cars Developments in light small plane technology will make it possible for everyone to own what are, in fact, flying cars. They will have closed cabins, heating, stereos and room for two people. You will take off from a field near your home and fly to towns and cities. After landing, you will take off the fixed wing and continue your journey by road just as if you were traveling by car. Fuel efficient engines and the advantage of being able to travel in the sky will keep costs and the environmental influence down. Flying for Fun The idea: Jet Packs The idea was a hit when a stuntman flew around on one during the opening ceremony of the 1984 Los Angeles Olympics, which was very successful. You'll be able to use the equipment-roughly the size of two scuba tanks fastened to your back-for short journeys. They will be handy for cleaning hard-to-reach windows, arriving in style at a party and shopping. Taxis The idea: driverless taxis These computer-controlled taxis will take you wherever you want along a fixed route, whenever you want to go. For the price of one person's bus fare, several people can ride at speeds of up to 25 mph, and there will be fences to guard against accidents. There will be little, if any, wait for the use of the taxis, which will leave from stations and will be used by prepaid cards. The taxis, which will travel on a 1.5 m-wide track, will use 75% less energy per passenger than a car and 50% less than a bus. We learn from the passage that flying cars _ .
Choices:
A. will operate only in the sky
B. will be more expensive than common cars
C. will have few bad effects on the environment
D. won't be equipped with things similar to what cars have | C |

It's 10:30 p.m. and 11-year-old Brandon Blanco is sound asleep at home. Suddenly, a loud noise wakes him up. Naturally, Brandon reaches for his cell phone. He blinks twice, and the message on the screen becomes clear: " R U awake?" But the late-night text does not annoy Brandon. He gets frequent messages and calls, even after bedtime. And he can't imagine life without them. " If I didn't have a cell phone, I wouldn't be able to talk to my friends or family as often," he told TFK. Brandon's use of technology doesn't stop there. He also has a computer, a TV and three video-game consoles in his room. With so many choices, it is no surprise that when he is not at school, he spends nearly every waking minute using one or more of these devices. Brandon is hardly alone. According to a recent study by the Kaiser Family Foundation, kids aged 8 to 18 are spending more time than ever before using electronic devices. How much time? More than seven and a half hours a day on average, the study found. That's about an hour more than just five years ago. The jump is the result of a huge explosion in mobile devices, says Victoria Rideout, the lead author of the study. Today, nearly seven out of ten kids have cell phones. Just five years ago, it was four out of ten. " These devices have opened up many more opportunities for young people to use media, whether it's on the bus, on the way to school or waiting in line at the pizza parlor," says Rideout. Often, kids multitask, or use more than one device at a time. " If you've got a chance to do something on your computer and take a phone call and have the TV on in the background, why not?" Media expert Cheryl Olson says. Most experts agree technology has much to offer kids. But some worry the kids could be missing out on other activities like playing outside or hanging out with friends. " It's a matter of balance," says Olson. " You've got to work on it." Multitasking while doing homework is another concern. Some kids listen to music, watch TV or use the phone while doing their homework. "It's important to make sure that you can stop and concentrate on one thing deeply," says Rideout. Logan Jones, 11, of Maumelle, Arkansas, describes himself as a "game freak". Still, he is glad not to have unlimited time with his PlayStation 2. "I'll tell my mom I'm going to play a game, and she'll say, 'Okay, but only for 30 minutes,'", Logan told TFK. With new and exciting devices hitting stores every year, keeping technology use in check is more important than ever. " Kids should try," adds Rideout. ":But parents might have to step in sometimes." It can be learnt from the text that _ .
Choices:
A. Brandon feels annoyed about his late-night message.
B. Olson is against teenagers' using mobile phones.
C. many teenagers lack friends in their middle school
D. kids have too many electronic devices to choose from | D |
mmlu | Question:
Whether you admit it or not, music improves our daily life and makes us feel easy, especially the music of Beethoven and Mozart. But can you believe that a school in England is using classical music to cut down students' bad behavior? The head teacher Brian Walker at the West Park School in Derby asks some students to stay behind after school on Fridays. He forces his students to listen to Mozart and other classical music. He also makes them copy his favorite poems and they have to watch educational videos. Mr. Walker says his main aim is to stop noisy pupils causing trouble in class for students who want to study. He said the students staying behind were "not the smokers or drinkers, the truants or the people who are late for school...It's those who have slowed the learning and teaching in class for everyone". Mr. Walker said this was unacceptable, because it was making the rest of the students fail to focus their attention on their study. Mr. Walker believes what he does reminds students that education is something to value. "It helps them see they are part of something bigger that will improve their life chances," he said. The head teacher thinks students in fact learn from being kept behind after school. "Hopefully, I open their ears to an experience they don't normally have and don't want to have again, so it's both educational and acts as a warning." Music has had success elsewhere in reducing bad behavior. In 2004, it reduced crime on London's subway by 25 percent. Researchers from a Belfast university found it helped stop elephants' bad behavior. However, one West Park student called Kieran said, "An hour of Mr. Walker's music is a real killer." Why does Mr. Walker say some students' bad behavior is unacceptable?
Choices:
A. Because the rest of the students hate them.
B. Because they are wasting their life.
C. Because they are disturbing teachers.
D. Because they have a bad influence on the other students. | D |

Mr. Ma, a famous mental doctor from Beijing once said at an important meeting, "Now many young students can have problems with their minds. Some students become worried because they have to study very hard. Others have trouble getting on well with people around them like their parents and classmates. Parents and teachers should care more about this problem." Then Mr. Ma gave some examples. One patient, a middle school students from Xi'an was doing badly in his lessons. He thought his teachers and friends often laughed at him, and he became so nervous and worried that one night he left his home without telling parents. Another student, a 14-year-old schoolgirl from Shanghai, was very afraid of exams. While she was reading the exam paper, she couldn't think of anything to write. A recent report fromJiefang Dailysays about 18% of the young students in Shanghai have mental problems. They often felt worried and very unhappy. Unluckily many of them won't go and ask for help. Some think they will look _ if they go to see a doctor. Others won't talk about their secrets. At the end of the meeting, Mr. Ma offered some good ideas to young people: u Talk to your parents or teacher often. u Take part in group activities. u Try to get on well with the people around you. u Go to see a doctor if you often feel unhappy. The students who often become worried or have trouble getting on with others may have _ .

mmlu | Question:
Next time a customer comes to your office, offer him a cup of coffee. And when you're doing your holiday shopping online, make sure you're holding a large glass of iced tea. The physical sensation of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions--those are the practical lesson being drawn from recent research by psychologist John A. Bargh. Psychologists have known that one person's perception of another's "warmth" is a powerful determiner in social relationships. Judging someone to be either "warm" or "cold" is a primary consideration, even trumping evidence that a "cold" person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies' conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth "mother" rather than one made of wire, even when the wire "mother" carried a food bottle. Harlow's work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills. Feelings of "warmth" and "coldness" in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as "warm" or "cold" is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries. To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study's hypotheses , handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form. The drink was then handed back. After that, the students were asked to rate the personality of "Person A" based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink. "We are grounded in our physical experiences even when we think abstractly," says Bargh. We can infer from the passage that _ .
Choices:
A. abstract thinking does not come from physical experiences
B. feelings of warmth and coldness are studied worldwide
C. physical temperature affects how we see others
D. capable persons are often cold to others | C |

Matt and his wife lived in the country. Matt was very mean and hated spending money. One day a fair came to the nearby town. They went to the fair and looked at all the things to buy. Matt's wife wanted to buy a hat only costing $28, but was refused. Later on, a comb of $5 attracted her attention, but he would not let her spend any money.

Henry Edwards Huntington Henry Edwards Huntington was born in 1850 in Oneonta,New York.In 1872 he went to work for his uncle,one of the owners of the Central Pacific Railroad.Twenty years later, Huntington moved to San Francisco at his uncle's request to share management of the Southern Pacific Railroad.On the way to San Francisco,he visited San Marino,and later bought it,which is home to his collections today. In 1902,Huntington moved his business operations to Los Angeles,where he developed the street railway system that created the structure of the Los Angeles area.He greatly expanded the existing electric railway lines,creating an extensive inter-urban system providing the transportation necessary.Huntington's business interests continued to grow particularly in the areas of water,power,and land development;at one time he served on as many as 60 corporate boards throughout the United States. At the age of 60,he announced his decision to retire in order to devote time to his book and art collections and the landscaping of the 600acre farm.In 1911 the large Beaux Arts building,in the charge of the architect Myron Hunt,was completed.

mmlu | Question:
When raising children, the small things make big differences in development . Because children are people, not machines, different children need different things, and buying band name clothing and having the perfect haircut or the biggest collection of expensive toys are not the kind of attention that they need. These kinds of things will make children feel rejected and teach them that material things and appearance are more important than love. Children need the attention from their parents. The areas of their lives and the abilities that get the most attention will develop the most. If the majority of parental attention is given to the way they stand or to finishing tasks, these areas will become more developed. When parents focus on finding faults, children will eventually take in all of that criticism. These methods often lead to unmotivated children with low self-esteem . Children need attention to be given to the details of their lives. They need encouragement from their parents. Statements like,"It makes me happy when you play nicely with your brother" will make a child feel good . Identify the specific talent, how it is used, and your reaction to it. Train the young minds to search for their talents with the same kind of attention to the details that may have previously been devoted to fault-finding. It also helps to identify personal qualities to praise rather than external ones based on appearance. Focusing on the details when children do good things is important. They need to know exactly what they did was good and how it made you feel .Parents often spend too much time looking for faults. When parents focus on good things, it results in motivated children with high self-esteem. _ ) are also. Why is fault-finding bad for children?
Choices:
A. Because fault-finding will teach children material things are more important.
B. Because children may imitate their parents.

"Interest in learning Chinese among American youth and their parents has grown dramatically in the past five years," said Vivien Stewart at the Asia Society, a US grow trying to bridge the gap between Americans and people of Asia and the Pacific. China, the world's most popular nation, is very important to the United States because it is a leading trader, consumer and investor. Its political influence is also rising across the globe. It has replaced the United States as the world's largest consumer and could become the second largest economy country in the world, after the superpower status and its telling effects politically, economically and culturally are driving the interest to learn the language, experts say.

Imagine life without the Internet -- not being able to chat with your friends or look up information for your homework or research project. That is the reality for nearly two-thirds of our world's population, either because they cannot afford WiFi access or are located in remote, inaccessible areas. Now Google has decided to do something about that. Google's Project Loon will attempt to send balloons high up into our earth's atmosphere in 2015. Each balloon will be equipped with a mini computer and a WiFi radio that will send Internet signals over the places it is floating over. The network equipment on Google balloons will communicate with a special antenna attached to each user's home. These antennae are in turn connected to a local Internet Service Provider. Each balloon will also communicate with each other to hand over signals as one floats out of an area, and another floats in. The balloons are 15 meters wide and made of a material that is three times thicker than the plastic bag at the supermarket. This helps them defend themselves against cold temperatures and changing air pressure. Google balloons will circle the earth at a height of 20 kilometers-- in a layer of our atmosphere known as the stratosphere . This is higher than the altitude at which planes fly. Once the balloons reach the desired altitude after being released from the earth, they will ride on air currents. What keeps these balloons from flying away? They will be controlled by people at the Project Loon command center. A pump operating on solar power will fill the balloon with gas to raise it or let gas out to lower it, based on instructions. This allows the balloon to float on different air currents which are moving either clockwise or anti-clockwise. There is no doubt that this technology can bring education to many children, weather information to farmers, and communication to natural disaster areas. However, one big question remains -- will some countries be comfortable with balloons above their heads? There could be concerns about spying and other problems. According to the text, Google balloons_.
Choices:
A. are as big as plastic bags at a supermarket
B. will float in a certain area for a long time
C. are equipped with a radio telephone
D. will be placed in the stratosphere | D |

The god of walls and mounts, whose duty was, and still is, to protect and be responsible for the welfare of the residents in these cities, villages, houses and temples. So a great and extremely hard task such as constructing a wall, which was supposed to run the length of the country, might not sound absurd . However, it is indeed a common mistake to think of the Great Wall as a single building structure, and it would also be a mistake to assume that it was built during a single dynasty. Actually, several dynasties somehow contributed to the construction of the Great Wall, the foundations of which had been laid many centuries ago. It was during the fourth and third centuries BC that warring states started building walls to protect their kingdoms, both against one another and against the northern nomads . The Great Wall played an important role in the growth of Chinese economy in history. Many settlements were established along the new border. Armies were instructed to reclaim wasteland and to plant crops there. Also, roads and canals were built. All of the work greatly helped increase the country's trade and cultural exchanges with many remote areas and also with the southern, central and western parts of Asia. According to the passage, constructing a wall running the length of the country _ .

A. was an order from the god of walls and mounts
B. was a completely absurd task

But, much to their disappointment, she did not mount the broomstick and take flight.

The old broomstick was put aside as she hobbled off towards the haystack followed by Sooty, a black cat she had rescued from a fox trap some time back. With only three legs, it was hard for Sooty to keep up with the old lady. The cat provided proof--the children were sure that only a witch could own a black cat with three legs. There, standing on a wooden box, was Mrs. Tailor, stretching out to gather her precious egg. Taking the egg in one of her hands, she began to climb down when, without warning, the box broke and the old lady fell. "We have to got and help her," whispered Amy.

In a world today of immense technology, population growth and economic flourish, planning for future residential and commercial developments needs careful analysis with well thought through assumptions about effects on the environment and the people of the community. One example of a growing city is Wooster, Ohio, my place of residency, Wooster in the last five years has grown considerably in population, leading to a growth in commercial business. Surrounded by farmland, Wooster's planning commission chose to extend the community into these farm areas in the form of residential and commercial areas. Picture this--corn fields, old trees, clean air, country roads, and wildlife are all part of the area. Within four years, the people living on this farm step outside on their front porch to view an extensive shopping center containing Wal-Mart, McDonald's, Wendy's, TCBY, and a Cinemark movie theatre. The once quiet road is now a city street with traffic lights, busy with automobiles day and night. The air smells of car exhaust and fast food. Some destruction of farmland is unavoidable when a city expands. Instead of expanding outward, planning commissions should consider interior _ of a city. Tearing down unusable buildings could remodel many areas inside the city. In addition, commercialized buildings could extend upwards to avoid unnecessary use of land. Environmentally, commercial expansion is harmful to the land. Besides forms of pollution, wildlife, including both plants and animals, is put at risk. A planning commission could have realized the benefits of environmental protection. Why not preserve the beauty and naturalness of the land while at the same time allowing for growth? With a steady growth of population and the need for more homes and more workplaces, many problems arise when planning for the future. The hillsides, fields and animal habitats need to be preserved while expanding cities. In the future, a world covered with concrete and asphalt could become reality. Serious research and analysis are needed when planning for the future of our home communities and for the entire globe to avoid such a miserable result. It can be inferred from the passage that _ .
Choices:
A. it is unavoidable to destroy farmland when a city grows
B. Wooster used to be a quiet and peaceful city surrounded by farmland
C. with many nationwide shopping centers, Wooster lost its uniqueness
D. commercial expansion has done no harm to Wooster | B |

Opposition is growing to the Berlin Zoo's plans to find a new home for Knut, the moneymaking celebrity polar bear whose popularity has been exploited by environmentalists and even Canadian tourism promoters. No longer cute, and just days before his second birthday, Knut will be given a new home that is expected to include a potential mating partner. The Berlin Zoo, facing the global economic crisis, can't afford the estimated $ 13 million it would take to acquire a female and a new home for them to share. "It's time for him to go--the sooner he gets a new home the better," said senior bear keeper Heiner Kloes. But some Berliners are beginning a campaign, collecting petition signatures and arguing that he's a tourist draw and a symbol as important as the Brandenburg Gate. "He means a lot to many people. When you're with him you forget your problems," Hartmut Wiedenroth, co-founder of the campaign, told Spiegel Online. Knut became an international celebrity in 2007, drawing huge crowds to his cage and _ sales of thousands of Knut toys and Knut-shaped candies. The Vancouver-based Canadian Tourism Commission made Knut a major part of its "Canada--Keep Exploring" campaign to draw tourists to the country-- and especially to polar bear country in northern Manitoba to see them in their natural habitat. Environmentalists also used the bear to promote the fight against global warming. But Knut's popularity diminished as his size increased to 210 kilograms, He was photographed at one point snapping at a child near his cage. In September his keeper, Thomas Doerflein, died of a heart attack. Doerflein, who became a celebrity himself after nursing the tiny ball of white fur when Knut's mother rejected him, had been re-assigned shortly after Knut's first birthday. Some animal rights critics said Knut has been showing unusually aggressive behavior because of his unnatural upbringing. The Berlin Zoo intends to find a new home for Knut mainly because of _ .

However, in my friend's opinion, we forget that when attending a regular school, the child is not into socializing all the while. The child is restricted to so many other activities. Studies take a major role in a child's life. The child hardly has the time to interact at school. The child might be meeting and studying along with many peers; however, how many kids interact with all the kids in a class? But in homeschooling system, as my friend mentioned, the kid has all the time and can plan his day accordingly. During the day the child studies just like other school-going kids but with no burden of homework and project work, the child has so much free time in the evening as to effectively interact and play with peers. The quality time the child spends in education is really impressive. Homeschooled kids have the opportunity to socialize more often as they have a lot of time in their hands. They can also make socializing a regular habit. Just as my friend said, her child goes to a neighboring park almost every day and has a set of friends who go there daily. Other children get back home to finish off homework and project work whereas her child who is already through with studies gets the opportunity to spend time with family members. When I heard this, I really felt how lucky the child was. Definitely the child had a better opportunity to socialize when compared with my kid. However, I might not consider homeschooling for my kid, as I am so used to the conventional schooling system and feel regular schooling the safest bet. The author's purpose in writing the passage is to _ .

A. express his views on homeschooling
B. explain what homeschooling is

Dear Sir, I am writing to you about my stay at your hotel. My wife and I arrived on Saturday, 15thMay and stayed for a week. Though we were treated well and found the service excellent, we think there are one or two matters we should bring your attention. 1. We had hoped for a nice holiday from our busy work lives, and your advertisement said "comfortable and quiet". We want to have a chance to enjoy ourselves. However, we were always waken up by the noise every morning. Is it really necessary for the workers to start their repair work so early? 2. We had hoped to swim in your "wonderful pool". To our disappointment , we found that it was closed for the whole time of our stay. I hope you do not mind my writing to you about these things, but I would be happy if you could give me some explanation. As I said at the start, it is a pity, and your service is so good in other fields. I hope to hear from you soon. Yours sincerely Mr Hector Bradley , . What did Mr Bradley think about the swimming pool?
Choices:
A. He felt disappointed because the swimming pool was closed for the whole time of their stay.
B. He felt disappointed because the swimming poop was too small.
C. He felt pleased with it because he had a good time there.
D. He found it really wonderful, just like what was said in the advertisement. | A |
mmlu | Question:
By 2050 there will have been an extra 2.5 billion people on earth. And what will they eat? To solve the problem, we should have to double our food production. We can also develop a diet of algae , insects and meat grown in laboratories. Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops. They are already eaten widely in Japan and China and they are eaten by almost everything from shrimps to blue whales. They can fix CO2 in the atmosphere and provide fats and sugars. Man-made meat looks like meat, feels like meat and it is meat, although it's never been from a living, breathing animal. Instead, it is grown from cells in big containers. Moreover, studies show that producing man-made meat will use far less water, energy and land. China has developed "green super rice", a series of rice types which produce more grain and have stronger ability to fight against floods, salty water, insects and disease. We used traditional plant breeding techniques to cross-breed more than 250 rice types. Green super rice, which is enough to feed an extra 100 million people, will be planted widely in the coming years. Insects like ants are not on most European menus but at least 1,400 kinds are eaten across Africa, Latin America and Asia. Now, with rising food prices and worldwide land shortages, such insects are getting more and more popular. Not only are many insects rich in protein , low in fat and high in Ca and Fe, but insect farms need little space. And they can grow well on paper, algae and industrial wastes. In order to exist in the future, people have to _ .
Choices:
A. move to other planets
B. produce rain in laboratories
C. build new laboratories for food research
D. increase the food production or look for other food sources | D |

In an American classroom, a teacher asked a Chinese girl to answer a question. She stood up and smiled, without making any sound. The American teacher looked at himself and didn't see anything funny. So he asked her the question again.The girl just smiled but said nothing. The teacher was angry. He didn't know that the girl smiled to cover her embarrassment because she didn't know how to answer the question. In a dining room in Beijing, an Englishman was careless and dropped a plate. The Chinese who saw this began to laugh. The Englishman felt uncomfortable and even got angry."They are laughing at me," he thought. In fact ,the Chinese laughed not at the Englishman or his bad luck---whether he is a foreigner or a Chinese. The laughter has some feelings, don't take it so seriously ;laugh it off, it's nothing;such things can happen to any of us,etc. Which feeling is NOT included in the laughter when the Englishman dropped a plate?

The Friday after the American holiday of Thanksgiving is called Black Friday. It's said that it's the day that store ledgers move into the black and companies become profitable. On that day, retailers slash prices to get consumers to buy. It is also a time when many Americans start their Christmas shopping. VOA's Elizabeth Lee tells us how the economy may affect consumers on that bargain day. This day should be a shopper's dream. "It's just the deals, the sales and everything you can get for a lesser price," said Sandy Thomas, a shopper. But it's a nightmare for others. "I think it's crazy. I've done all of my shopping throughout the week so I don't have to go out on Friday," she said. It's called Black Friday, the start of the traditional Christmas shopping season in the United States. Every year it's the day after the Thanksgiving holiday. Stores open before sunrise and there are deep discounts everywhere you look. Last year a crowd of bargain-hunters killed a Wal-mart worker in a New York suburb. This year, many stores are increasing security while they slash prices. "This is a huge time for the retail stores," said Fred Joutz from George Washington University. "This is when they begin making their profits for the year." Economics professor Fred Joutz says how Americans spend the weekend after Thanksgiving is a good indication of how consumers feel about the future. With the unemployment rate above 10 percent, Joutz says Americans are saving more and spending less. Some retailers are attracting consumers by opening on Thanksgiving Day, when shops are traditionally closed. Other stores open their doors anywhere from midnight to four in the morning. And shoppers will be lining up in front of the doors in order to be one of the first ones to walk through and get a big discount. Electronics like flat screen TVs are usually the first items to go. Sandy Thomas says it's an annual family tradition and well worth it. "I just save maybe half of what I would have spent on a regular, you know, shopping trip," she said. Economists say U.S. consumers will spend money this Black Friday, but they will spend it more carefully. Why American people call it a black day?
Choices:
A. Because they organize activities in honor of some great person.
B. Because there are too many people going out shopping for Christmas.
C. Too many people are celebrating Thanks giving.
D. The sky is black that day. | B |

mmlu | Question:
The goal of earthquake prediction is to give early enough warning. The U.S. Geological Survey conducts and supports research on the likelihood of future earthquakes. Scientists estimate earthquake probabilities in two ways: by studying the history of large earthquakes in a special area and the rate at which strain accumulates in the rock. Scientists study the past frequency of large earthquakes in order to determine the future likelihood of similar large shocks. For example scientists researched the large earthquakes in the San Francisco Bay region during the 75 years between 1836 and 1911. For the next 68 years, no earthquakes of magnitude 6 or large occurred in the region. Beginning with a magnitude 6 shock in 1979, the earthquakes in the region increased dramatically; between 1979 and 1989, there were four magnitude 6 or greater earthquakes, including a magnitude 7.1 earthquake. So scientists estimated that the probability of a magnitude 6.8 or larger earthquake occurring during the next 30 years in the region is about 67 percent. Another way to predict earthquakes is to study how fast strain accumulates. When plate movements build the strain in rocks to a critical level, like pulling a rubber band too tight, the rocks will suddenly break and slip to a new position. Scientists measure how much strain accumulates along a fault each year, how much time has passed since the last earthquake, and how much strain was released in the last earthquake. This information is used to calculate the time required for the accumulating strain to build to the level that results in an earthquake. This simple model is so complicated that such detailed information about faults is rare. In the United States, only the San Andreas Fault System has adequate records for using this prediction method. Scientific understanding of earthquakes is of vital importance to the Nation. As the population increases, expanding urban development and construction encroach upon areas susceptible to earthquakes. With a greater understanding of the causes and effects of earthquakes, we may be able to reduce damage and loss of life from this destruction. That scientists study the history of large earthquakes in certain areas is to ultimately _ .

A. do research on the past frequency of large earthquakes
B. estimate the magnitude of similar earthquakes
C. forecast the possibilities of similar earthquakes
D. judge the specific location of future earthquakes | C |

Flight cancellations and loss of luggage can ruin even the best-planned holiday. The key to a stress-free trip is having a backup plan. Fly non-stop. The worst problems involve connections, so it is important to take non-stop flights whenever possible. If you do have to make a connection, try to route through a southern city, where snowstorms and de-icing delays will be less likely. Always allow at least two to three hours for flight connections. Check the weather. Check the weather in your connecting city, not just the arrival and departure city. If your departure flight is cancelled because of weather, you can go home or back to your hotel. Airlines promise to get you on the next available flight, not the next flight. That could be several days later on a sold-out holiday weekend. Go early. The earlier in the day you fly, the better your chance of getting rebooked the same day after a missed connection. It will also put you ahead of stranded passengers who arrive later. Rebook immediately. As soon as your flight is delayed or cancelled, get on the phone and rebook your flight instead of waiting at the ticket counter. If your rebooking is delayed, call or ask your travel agent to find a seat on another carrier, and then ask your original carrier to endorse your ticket to the new airline. Airlines are not required to do this but often do. Learn more at www. dot. gov/ airconsumer/ fly-rights. Ship bags. A few days before your flight, ship suitcases or holiday gifts to your destination by a documented express service. It's preferable to losing bags because of re-routed flights and sometimes cheaper than paying airline overweight bag fees. Know your rights. Airlines are not required to passengers for delayed or cancelled flights, but it never hurts to ask for goodwill vouchers for meals, taxis or a room. The suggested way for you to rebook your flight is _ .

A. through the phone
B. by waiting at the ticket counter

The worst danger is a house on fire when people are asleep. Always be ready to leave through a window into the garden by making sure you can open it if necessary. If you should be on holiday in a tall building or hotel, make sure you know where the fire escape is . When you can't find any way out, try to find pieces of cloth and make a rope to get out of a window to safety. If you smell burning in your home, get out right away. If you can't breathe properly because of smoke on your way out, crawl on your hands and knees because smoke rises and the air will be cleaner near the floor. Smoke is a killer and more people have died from breathing it in than actually being burnt. Fire in a cinema, hall or public place often means people pushing to reach a door. Keep your head up with arms up in front of your chest .This protects your chest and gives you the best chance to breathe. Above all, don't get frightened! In a room filled with smoke ,you'd better crawl on the floor because _ .

In the early hours of March 8, a Boeing 777 took off from Kuala Lumpur, Malaysia. Its destination was Beijing. But for unknown reasons, it never arrived there. There were 239 people on the Malaysia Airlines flight, including 154 Chinese. As of March 13, 12 different countries, including Malaysia, China, Vietnam and the US, were searching for the plane. The disappearance is an "aviation mystery", Azharuddin Abdul Rahman, the head of Malaysia's Civil Aviation Authority, said on March 10.There was no clear sign of a crash by March 13. Between 1-2 hours after takeoff, the plane suddenly lost contact with people on the ground. The weather was clear, and the pilots didn't make any calls . No evidence was found in the area where the flight last made contact. People are also talking about a possible hijacking . International police agency Interpol confirmed on March 9 that at least two passengers on the flight had used stolen passports to get on board. "We are looking at all possibilities," said Malaysian Transport Minister Hishamuddin Hussein. The incident is now being called simply a "plane disappearance". So, what are some possible causes of a plane disappearance? An AP story provided a summary. 1. A failure of the plane's body or its engines. However, even if both engines stopped working, the plane could still glide for up to 20 minutes, giving pilots time to make an emergency call. 2. Bad weather. Planes are designed to fly through most severe storms. However, in June 2009, an Air France flight from Rio de Janeiro to Paris crashed during a bad storm over the Atlantic Ocean. 3. A bomb. Throughout history, several planes have been brought down by bombs. 4. An accidental shoot-down by some country's military. In July 1988, the US Navy accidentally shot down an Iran Air flight. In September 1983, a Korean Air Lines flight was shot down by a Russian fighter jet. No matter how unlikely a situation, it's too early to determine what really happened to MH370. It could take months, if not years, to _ any possibilities, say experts.. What could be the best title of the passage?

In the near future, we may be using our eyes to operate our smartphones and tablets, even when it comes to playing popular games like Fruit Ninja. The GazeGroup has been developing eye-controlled computer technology for nearly 20 years. But those devices have been mainly designed to aid those with disabilities, and are very expensive. "After a while, we figured out that probably the best way is to go for a mass-market approach," says Gaze's Sune Alstrup Johansen, "where everybody would have this available." Johansen and some of his colleagues have formed a new company, The Eye Tribe, which is hoping to develop the technology on a mass commercial level. The technology works by sending an infrared light from the computing device toward the user's face. After measuring the user's eye movements, the technology is then able to easily know where a person's eyes are moving, allowing the eyes to control a cursor . A software can determine the location of the eyes and tell where the user is looking on the screen. It even knows which image he is looking at. There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world. Following Nintendo's popular Wii system, Xbox released the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. Since most smartphones and other mobile devices can't come standard with an infrared device, Johansen said a replaceable filter would be an inexpensive, convenient choice for most consumers. And even as companies like The Eye Tribe work to create a commercially practical product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for disabled users. "Then I can go to any computer, and then I can control it and I can use it, instead of just bringing my own," said Stig Langvad, who heads up Denmark's umbrella organization for people with disabilities. "So I'll be a part of society on an equal foot, instead of being a special solution." In order to use eyes to operate their mobile phones, most users should buy _ .
Choices:
A. a replaceable filter
B. the Kinect device
C. Wii system
D. Fruit Ninja | A |

The food we eat seems to have profound effects on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that 80 percent of all human illness are connected with diet and 40 percent of cancer is connected with the diet. Therefore, that food is connected with illness is not a new discovery. In 1940's scientists realized that nitrates , which are often used to keep color1 of meat, and other additives caused cancer. However these additives remain in our food and it becomes more difficult to know which additives are helpful or harmful. Farmers sometimes give drugs to animals not because the animals are ill but because they want to sell the animals at higher prices. For example, farmers try hard to make animals grow big so that they can sell the big animals for more money. Although the Food and Drug Administration has tried again and again to control farmers to do so, farmers go on doing this. According to the passage, what has science done to mankind?
Choices:
A. Because of science there is no polluted food any more.
B. Science makes food have less value.
C. As a result of scientific invention, some things that may be harmful have been added to our food.

Probably you have seen photographs of the Grand Canyon , the great valley in the desert country of Arizona. But you must go there yourself to feel its true size and beauty. Tie Grand Canyon is one of the greatest natural wonders of the world. The Colorado River formed the Grand Canyon over mil lions of years. Slowly, the river cut down through hard rock. At the same time. the land was rising. Today. the canyon is one and a half kilometres deep and 445 kilometres long. The el dest rocks at the bottom of the canyon are more than 1 billion years old. The width varies from about 200 metres to 29 kilo metres across. The rim or top of the canyon is about 2, 300 metres above sea level tin the South Rim, and about 3,000 metres on the other side, the North Rink As a result, there are different kinds of plants and animals on opposite sides of the canyon. The South Run is dry desert country. The North Rim has tall forests. The canyon looks different at different times of day. and in different seasons and weather. At sunrise anti sunset the red. gold, brown, and orange colours of the rocks are especially dear and bright. In winter, the canyon is partly covered with snow. The view from the South Rim of the Grand Canyon is the best. Most visitors come to the South Rim and stay in camp- grounds or hotels. Every point along the canyon' s edge offers a different view. The North Rim of the Canyon is quieter, h takes all day to drive there from the South Rim because there is only one bridge across the Colorado River. On the way, you go through Navado Indian lands, and a colourful pink desert called "The Painted Desert". You can walk clown into the Grand Canyon, or you can go down oil the back of a mule . You can also lake a boat trip down the Colorado River, and camp on the bea ches at night.

mmlu | Question:
Many people who are overweight have poor digestion . For the most part, poor digestion is not a habit given by our parents. We give it to ourselves through the way we eat. Oh, poor digestion can lead to weight problems. Here's how: When a person feels stressed, the part of the central nervous system that connects digestion switches off. This is called the parasympathetic nervous system . At those times of stress, the body can take in food and process some of it, but digestion doesn't work correctly to digest all the nutritional goodness from the food. Poor digestion is not always obvious by observing symptoms; you can get some illnesses but not always. Poor digestion can be seemingly silent. If you eat when you are stressed, anxious, or nervous, you might as well be eating cardboard for all the nutrients your body gets. Yes, eating when stressed is a gaining situation. Now you might think, well, if I'm not digesting, the calories aren't getting handles, so I should be losing weight. Good idea, but wrong reality. When digestion is not proper, the body starts "starving" from lack of necessary nutrients . Yes, it goes into a starvation problem and starts absorbing fat and energy. It thinks it's in a famine . The good news is that it's easy to make some corrections and get rid of stress at mealtimes. If you feel stressed often, it can be helpful to take other food that contains multiple B vitamins. These help, but you could still find yourself stressed at mealtimes. Which is NOT the reason why people may have weight problems when eating with stress?
Choices:
A. The body does not take in what they eat.
B. The digestion system becomes incorrect.
C. People cannot eat much when unhappy.
D. The body will begin to absorb too much fat. | C |

I knew I was all right now. Nobody else would come ahunting after me. I got my traps out of the canoe and made me a nice camp in the thick woods. I made a tent out of my blankets to put my things under so the rain couldn't get at them. I caught a catfish and towards sundown I started my camp fire and had supper. When it was dark I sat by my camp fire, feeling pretty satisfied; but by and by it got sort of lonesome, so I went and sat on the bank and listened to the current crashing along, and counted the stars and drift logs and rafts that came down, and then went to bed; there was no better way to when you are lonesome; you can't stay so, and you soon get it over. And so for three days and nights. No difference--just the same thing. But the next day I went exploring around the island. I was boss of it; it all belonged to me, and I wanted to know all about it; but mainly I wanted to spend the time. I found plenty of strawberries and green summer grapes; and the green blackberries were just beginning to show. Well, I went fooling along in the deep woods till I judged I wasn't far from the foot of the island. I had my gun along, but I had shot nothing; it was for protection. About this time I almost stepped on a goodsized snake, and it moved quietly and smoothly through the grass and flowers, and I was after it, trying to get a shot at it. I clipped along, and all of a sudden I bounded right on to the ashes of a camp fire that was still smoking. My heart jumped up among my lungs. I never waited to look further, but unlocked my gun and went sneaking back on my tiptoes as fast as I could. Every now and then I stopped a second among the thick leaves and listened, but my breath came so hard that I couldn't hear anything else. I moved quietly along another piece further, then listened again; and so on. If I saw a stump , I took it for a man; if I stepped on a stick and broke it, it made me feel that a person had cut one of my breaths in two and I only got half, and the short half, too. Why did the boy always carry his gun with him wherever he went?

B. To protect himself.
C. To hunt some animals for food.
D. To play with it for fun. | B |
mmlu | Question:
What is your favorite color? Do you like yellow, orange, and red? If you do, you must be an optimist , a leader, an active person who enjoys life, people and excitement. Do you prefer grays and blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference , and the effect that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly. A yellow room makes us feel more cheerful and more comfortable than a dark green one, and a red dress rings warmth and cheer to the saddest winter day. On the other hand, black is depressing . Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray. Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief. According to this passage, _ .

mmlu | Question:
Everyone, please imagine, a big explosion breaks out as the plane takes us high in the sky. The plane is full of smoke and the engine sounds scary. Two minutes later, the engines are turned off. We are now sitting in a plane with no sound. And we can see: Life is over. That really happened. In January 2009, I had a front-row seat on Flight 1549, the plane that crash-landed in the Hudson River in New York. Now let me tell you the three things I learned when the silence came. First, I thought about all the people I wanted to reach out to but didn't. I thought about all the experiences I wanted to have but never did. I no longer wanted to put off anything in life. Second, I really regretted the time I wasted on things that did not matter. I decided to remove negative energy from my life. Third, I realized, wow, dying was not scary. But it was very sad just because I only wished I could have seen my kids grow up. Fortunately, I was given the gift of a miracle of not dying that day. I was given another gift, with which I was to see into the future and come back and live differently. About a month later, my wife and I were at a performance by my daughter, not much artistic talent. Yet, I'm crying. I realized that above all, the only goal in my life was to be a good father. Audience, again, imagine the same thing happening on your plane. How would you change? What would you get done? And more than anything, are you being the best parent you can? Thank you. What is the author's final goal in life?
Choices:
A. Never to put off anything in life.
B. To remove negative energy from life.
C. To see his daughter grow up.
D. To be a good father. | D |

Norah had a cottage on a cliff above a big bay. In winter it could be very unpleasant because of strong winds and sea waves. In fact, when a _ was blowing, Norah and her husband got used to sleeping in a small room downstairs, because their bedroom upstairs, which faced the gales, had a very big window, and they were afraid that an extra violent wind might break it and blow pieces of broken glass over them. Also, the salt wave from the sea put an end to many of the colorful plants Norah planted in her garden. She tried putting up a fence to protect them, but the wind just hit it, went up over the top and then down the other side, so in the end she filled the garden with trees and bushes that liked salt. But most of the summer Norah enjoyed her cottage and garden very much. At weekends she could sit out-of-doors in the sun, looking at the beautiful view, with interesting ships and boats passing by, and she could very easily cycle down to the sea for a swim. Now, Norah and her husband had plenty of friends and relations. In the summer lots of them used to come to enjoy the beautiful place, and in the end it really became quite annoying for the couple. When they were at home, they found friends and relations arriving, expecting to be given unlimited drinks and meals, and to sit in the sun for hours, talking as if Norah and her husband had nothing else to do but entertain and listen to them. This went on for several years. Norah didn't wish to appear rude by refusing to let her friends and relations in, but on the other hand, she was getting tired every summer. Then one day Norah was complaining about this to her hairdresser while she was doing her hair. "You're disturbed by too many uninvited guests, are you?" said the hairdresser. "Why don't you try my way of escaping?" "What's that?" asked Norah. "Well," the hairdresser answered, "when the bell rings, I put on my coat and take my shopping bag. If it's someone I don't want to see, I say innocently, 'I'm sorry, but I've got to go out.' But..." We can infer that _ .
Choices:
A. lots of friends cam to visit them in winter
B. few friends came to visit them in winter

Many television programmes are very realistic. One who watches TV often feels that whatever happened in the film could well happen to him. With only a little imagination, every man in the street becomes a thief, a spy or a murderer. Jane had been watching a spy film at her friend's house. In it, a young girl had been followed and murdered. She felt a little frightened, walking to the station. She took a train back to the centre of the city. There were a lot of people traveling with her, so she felt much safer. A man sitting opposite her, reading a newspaper, glanced at her. She thought nothing of it until she saw him staring at her. Remember the film and feeling very uncomfortable, she got off the train and went to the bus stop. When he got on the same bus as she did, she found that he was following her. As long as she had been with other people she wasn't frightened. But when she got off the bus, the streets were almost empty. She walked as quickly as she could. She could hear footsteps following her but she didn't dare to look around. After what seemed to have been hours, she was unable to find them, because she was so frightened. The footsteps stopped behind her. She felt a hand on her shoulder. Instead of feeling hands round her neck, however, she heard a pleasant voice. "I apologize if I frightened you.

mmlu | Question:
These days, it's easy to fly across oceans for vacation. Centuries ago, however, crossing the open seas required thorough and accurate planning, handmade boats, and courage. Scientists and historians have long been looking for clues to explain who crossed which oceans first. When it comes to the trip between Polynesia and South America, chickens may have been among the first ocean voyagers, according to new evidence. After studying an ancient chicken bone, anthropologists from the University of Auckland in New Zealand now say that people and chickens traveled from Polynesia to what is now Chile by about 620 years ago. By then, the Inca people were already living in South America, but the Polynesians would have been the first to get there by sea. Previous theories claimed that European explorers and their chickens sailed to South America first -- but those voyagers didn't arrive until about a century later. In 2002, archaeologists dug up 50 chicken bones from a site in Chile called El Arenal. The team from New Zealand analyzed one to these bones. According to their calculations, the bone is about 650 years old. The researchers also compared the genetic material, or DNA, from the South American chicken bone with DNA from 11 chicken bones that had been found on the Polynesian islands of Tonga and American Samoa. These islands are 6,000 miles west of Chile. The bones found on the Polynesian islands are been 600 and 2,000 years old. Results of the comparisons showed that the chicken bones from both the Polynesian and South American sites had part of DNA in common. The researchers found the same part of DNA in feathers of two living chickens in Chile that belong to a modem breed that lays blue eggs. That DNA evidence suggests a close relationship among the chickens. "However, the weight of scientific evidence is now behind the hypothesis that it was seafaring ( ) Polynesians who sailed from the islands to South America and returned," says archaeologist Patrick V. Kirch of the University of California, Berkeley. What is the passage mainly about?
Choices:
A. It was difficult for ancient people to travel between Polynesia and South America.
B. The first people who lived in Chile and Polynesia.
C. Valuable chicken bones have been found in Chile.
D. Chickens -- the first to travel between Polynesia and South America. | D |

How many times have you heard the expression that most people spend more time planning their vacation than they do planning their lives. I would explain that expression by adding that most people spend more time "thinking" about their vacation than they do thinking about what's important in their life. While rest and relaxation are a must in living a balanced life, it's not what we were created to do. After all, the Master Creator took his R&R (Rest and Recreation) on the seventh day, only after six days of "definitely directed thought." 1 My friend Mike Litman wrote an article this week. 2It's called "The Millionaire Composite" and it analyzes one of the big differences between super-successful people and everyone else. He wrote "I recently visited a Real Estate Multi Millionaire Mogul. What did I see next to his desk? His vision statement, along with a list of what he values in life-handwritten." "A few months back, I interviewed an individual Marco Dorigo who sold over a billion dollars worth of products on television. He told me that he read his life and business vision and goals daily, and that he took time to imagine exactly what he wanted to create each night before falling asleep." What is your life's purpose or your personal task statement? Is it written down? Do you review it and think about it often? 3Is your life organized around your purpose and a set of goals that support that purpose? Without purpose and goals - certainly directed thought-you are like "ship without a rudder. " There is power in your purpose and in your goals.4 One of my favorite passages of James Allen is one he wrote in The Mastery of Destiny: "All successful people are people of purpose. They hold fast to an idea, a project, a plan, and will not let it go; they treasure it and develop it; and when upset by difficulties, they refuse to give in; the greater the difficulties are, the stronger the purpose is. " And that's worth thinking about. The supporting sentence "It is the power that helps you out of difficulties, the fuel that drives you toward the life you want." should be placed at_.
Choices:
A. 1
