mmlu_train_62418 | Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year a Canadian scientist George Kill proved the English professor was right. Dr Kill filled an open oil pail with cold water. He filled another with warm water. He put both in the same low temperature. The warm water froze first. The lack of covers on the pails is the secret. Some of the warm water changed into vapor. This meant that less of the warm water was left to be frozen. And so the warm water froze faster than the cold water even though it had a greater temperature drop to make. What Sir Francis Bacon said was right, but people didn't believe him until _ . | [

mmlu_train_8455 | Rare birds in the UK have been living far better than the more common birds over the last decade due to the efforts of conservation organisations, according to a new assessment. The research shows almost 60% of the 63 rare birds that live in the UK have increased over the last 10 years. By contrast, only about one third of common species have increased over the same period. Just 28% of rare birds have decreased over the same period, compared with four out of every 10 common birds. The rare birds described in the assessment with increasing populations include theosprey andcorncrake . All of these birds are subject to conservation action. The declining common birds include the nightingale,swift , house sparrow and redgrouse . These are suffering declines for a variety of reasons, including changes in farming practices. Dr David Noble, from the British Trust for Ornithology, said: "That some of our rarer birds have responded to targeted conservation action is great news. It shows just what can be achieved. What we need to do now is to continue the good work and use some of the lessons we have learned to help our more common birds." Dr Mark Avery, the conservation director of the Royal Society for the Protection of Birds (RSPB), said: "Over the last decade we've enjoyed some great conservation successes, including removing some threatened species from the World Conservation Union's Red List of Thratened Animals and increasing the populations of red kite, osprey, etc. However, these successes arecountered by continued declines of some widespread species." The overview of 210 native birds has been produced by a group of conservation organisations, to mark the publication ofThe State of the UK's Birdsreport, which is in its l0th year. The report was published by the RSPB for a group of conservation organisations. The passage is most likely to be found in a book about _ . | [

mmlu_train_35493 | Can you imagine that several hundred years ago, tomatoes were seen as _ food in Europe? What made Europeans believe this was John Gerard's publication of Herbal in 1597. Gerard wrote: "The leaves and stalks of the tomato plant are toxic." Undoubtedly, Gerard's opinion was based on a misunderstanding of tomatoes. But his opinion was widely spread in Britain and North America for over two hundred years. In the late 1700s, a lot of Europeans held more fears for tomatoes. A nick name for the fruit was "poison apple" because it was believed that aristocrats got sick and died after eating them. But the actual reason was the pewter plates they used. Since tomatoes are high in acidity, when placed on the plates, the lead in the plates would dissolve . This caused many deaths. Unluckily, no one knew this at that time. So the innocent tomatoes were picked as the killer. Today, more than one and a half billion tons of tomatoes are produced every year around the world. Tomatoes are cooked in various ways. This healthy and tasty food finally wins its innocence back. When did people begin to eat tomatoes according to the text? | [

mmlu_train_8803 | Of all the websites,one that has attracted attention recently is _ .Most of this attention has come from the media and tells every reason why the website should be shut down.The threat of internet predators is indeed a tough reality,but shutting down the site is not the answer.If _ were shut down,another site would quickly take its place.Therefore,the right way is to teach teens how to use the site safely and educate them about who may be predators and how to avoid them. The key to staying safe on the Internet is to make sure that your profile is secure.The simplest way is to change the privacy setting on your profile to "private", which protects your information so that only the people on your friend list can view it.Although this is effective,it is not perfect.Predators can find ways to view your profile if they really want to,whether through hacking in or figuring out their way onto your friend list.Thus,you should never post too much personal information.Some people actually post their home and school addresses,date of birth,and other personal information, often letting predators know exactly where they will be and when.The most information that is safe is your first name and province.Anything more is basically inviting a predator into your life. Another big issue is photos. I suggest completely skipping photos and never posting a photo of a friend online without asking permission. Most importantly, never,under any circumstances,agree to a real-life meeting with anyone you meet online.No matter how well you think you know this person, there are no guarantees that they have told the truth.But you could feel free to chat with people you meet on the site, but just remember that not everyone is who they say they are.Hopefully,the next time you edit your profile,you'll be more informed about the dangers of internet predators and take the steps to defend yourself. We can learn from the passage that_. | [

mmlu_train_52826 | I asked Jackie a lot of questions. I asked if she became close to her patients. She said, "Some I do, especially if I have become their close friends and they tell me things they wouldn't tell anyone else. I've found it harder for the patient's family to accept what's happening. In most cases, the dying person has accepted the truth." I asked her how she could do this work for so long. She said, "I have taken care of 3,000people over 37years. I consider dying to be a very important part of life. I feel good because I can make these people's journey easier." Jackie was the mother I have never had. My own mother, Helen, was taken away from me right after I was born. I never knew her. And I had a strange relationship with my father. He was a Sunday father. Since my sister and I lived in foster homes, he came to visit only on Sundays. But at the hospice , nurse Jackie gave me hope, love and encouragement. She listened to all my stories, and I listened to hers. It was a comfort. The nurses had told my family that death was coming near. As time went on, I became the star patient at the hospice, because I didn't go according to plans. My kidneys started working again and could function without dialysis .

mmlu_train_25275 | What is the E-mail The e-mail, which is also called email, stands for "electronic mail". You can send messages in only a few seconds by e-mail. On the Internet there are many powerful computers called "servers" to help people send and receive emails. The sending and receiving servers are just like post offices. If you want to use the email service, you have to open at least an email account called a "mailbox", just like we set up a mailbox in a post office. Some mailboxes are provided free of charge by ISPs, which you can get when you open an Internet account. Most widely used mailboxes are provided free by the ISPs, and anyone can apply for one even if he has no ISP account. How to apply for a free mailbox? First you have to connect to the Internet and go to the homepage of the ISP providing free mailboxes. Then you'll find an icon showing "apply for a free mailbox", click the icon, an agreement about the rules for using the free mailbox will appear. If you want to go on, click the icon "I agree". Then you have to fill in a form about your basic personal information, and the name and pin of the mailbox. The pin is the key to the mailbox. After finishing these, you'll get a mailbox like this: your name @ mail server, for example: jack@ 163. com. The mailbox is separated into two parts by a separator "@", which is read as "at". The former part is the name of the mailbox. The latter is the domain name of the mail server. All mails to you will be received by the server and put into your mailbox. You can read this mail on any computer in the world as long as you have the name and pin of the mailbox. Here is an email address ecpjyb@ecp.com.cn. What is the name of the mailbox? | [

The Chinese Medical Doctor Association released the 2013 China Sleep Quality Index on March 19 to mark World Sleep Day---March 21. According to the index,nearly a quarter of Chinese people don't sleep well.Half said that they feel tired after getting up and 15 percent people have trouble falling asleep. Ye Jingying,a sleep expert at Beijing Tongren hospital,says:"If people often wake up during the night,or always feel weak and tired in the day,they should pay attention to their sleep pattern." Many people play with their cell phones or i pads before sleeping.The report said that this is one of the main reasons for bad sleep.Other reasons include stress and bad moods. How to sleep well? Above all,get enough sleep.Seven to nine hours of sleep every night is perfect for an adult,and eight to nine hours is best for a teenager. Forming good sleep habits is important.The report suggested that people need to keep away from digital devices for at least an hour before sleep. The lights keep their brains excited for a long while.Other suggestions include:try to go to sleep and wake up at the same time every day,even on weekends and during holidays,and do the same relaxing things before bed each night,like listening to soft music.

mmlu_train_57734 | Parents in three Midwestern states will soon know just how good or bad their kids' driving is when their children take the car for a spin . Starting today, American Family Insurance is offering customers with teen drivers free cameras that record what happens when a sudden change in the car's movement occurs. The cameras record the action inside and in front of the car in 20-second audio-video clips . The clips are then transmitted to Drive Cam, a prefix = st1 /San Diegocompany that analyzes the clips for risky behavior. Among things the analysts look for is the response time of the drivers and if they are paying attention to the road. Parents can receive a report on their kids' driving and view the clips on a home computer. Car accidents are the leading cause of death among U. S.teens, according to the NHTSA(National Highway Traffic Safety Administration). "There will be fewer accidents," Rick Fetherston, vice president at American Family said of the new system. American Family will test the system out by offering it for free for one year to 30.000 families in Wisconsin, Indiana and Minnesotato see whether the system results in fewer accidents. If the system is proven to prevent accidents, customers who volunteer to use it might see their insurance premiums drop. The company would not be viewing the videos or individual score cars, unless there is an accident. Bruce Moeller, president of Drive Cam, says his company's system is already being used by companies with lots of cars. "Some of our customers are reporting a 30% to 90% reduction in their risky driver events," Moeller says. But a lawyer in Minneapolissays. "If I felt I needed a camera in the car to watch over my kids, I shouldn't be letting them drive." American Family tested the system in two high schools in Minnesota and Wisconsin. Megan Ireland, 17, said the camera caught her stopping too late and taking turns too fast. The student at Prior Lake High School in Savage, Minn., said she didn't like it because she felt it invaded her privacy but has warmed up to the system. "Now I don't really have a problem with it because it's made me a better driver," she says. "For real." The camera is being offered to _ by _ free of charge now. | [

mmlu_train_37131 | We all know that eating junk food can make us fat. However, a new study suggests that it can do more than that - it can also make us lazy, reported CBS News. In the study, researchers at the University of California, Los Angeles, US divided 32 female rats into two groups. The first group was fed a diet of healthy food such as corn and fish, while the second was given a diet of highly processed food rich in sugar, namely "junk food". Within three months, the rats in the second group were already much fatter than those on the healthy diet. And when researchers trained the rats to do simple tasks, they found even more differences between the two groups rather than weight. During the task - pushing a lever to receive a reward of sugar water - the rats on the junk food diet were found to be less willing to move, and they took longer breaks between each push than the lean rats did. "It is as if the rat is thinking 'This is too much work'," Aaron Blaisdell, leader of the study, told the Los Angeles Times. But what about the possibility that the fat rats were less passionate about getting sugar water because they were already eating lots of sugar in their daily diet? That's why researchers repeated the tests by rewarding fat rats with plain water when they were extremely thirsty. However, the results came out just the same. According to researchers, these differences suggest that junk food changed the chemistry in the rats' brains. The experiment didn't end _ . After six months, the rats' diets were switched, and the overweight rats were given a healthy diet for nine days. However, this change didn't help reduce their weight or improve their ability to perform tasks, which means the effects of their junk food diet persisted . "There's no quick fix," said Blaisdell. For a long time, we've believed that people become fat because they are lazy. But this study has proven the opposite to be true as well, which indicates that laziness and obesity are a "vicious cycle ". So, if you constantly feel tired, lacking any urge to get up from your chair, it could be that you've been studying too hard. But you should also pay attention to your diet. We can conclude from the article that _ . | [

mmlu_train_82770 | For thousands of years, people have used plants to make medicines. They used different parts of the plants --the roots, the leaves, the flowers, and the bark . Today, doctors have rediscovered more medicinal values of some plants. Let's look at some examples. Foxglove is a common plant. People have used it to make the heart slow down. Recently scientists have developed another drug from it. This new drug helps prevent other heart problems. In some areas, _ has been a problem. Scientists have learned that the bark of a South American tree, the cinchona, can be made into a drug to prevent malaria. For a long time, the Chinese have known that a special plant, wormwood, can also fight malaria. Scientists have been working with it to develop new drugs against malaria. In Germany, some scientists studied garlic for four years. They found that it helps prevent the build-up of plaque because too much plaque is bad for health. This very common plant continues to be studied. As we know, there are about 250,000 kinds of flowering plants in the world. Scientists have only studied little more than one percent of plants for their medicinal value. Maybe medicines for AIDS and cancer will be made from the other 99 percent.

mmlu_train_6051 | Email has brought the art of letter writing back to life, but some experts think the resulting spread of bad English does more harm than good. Email is a form of communication that is changing, for the worse, the way we write and use language, say some communication researchers. It is also changing the way we interact and build relationship. These are a few of the recently recognized features of email, say experts, which should cause individuals and organizations to rethink the way they use email. "Email has increased the spread of careless writing habits," says Naomi Baron, a professor of linguistics at an American university. She says the poor spelling, grammar, punctuation and sentence structure of emails reflect a growing unconcern about the way we write. Baron argues that we shouldn't forgive and forget the poor writing often shown in email. "The more we use email and its tasteless writing, the more it becomes the normal way of writing," the professor says. Others say that despite its poor writing, email has finished what several generations of English teachers couldn't: it has made writing fashionable again. "Email is a critical new communication technology." says Ian Lancashire, a professor of English at Toronto University. "It fills the gap between spoken language and the formal methods of writing that existed before email. It is the purest form of written speech." Lancashire says email has the mysterious ability to get people who are usually scared by writing to get their thoughts flowing easily onto a blank screen. He says this is because of email's close similarity to speech. "It's like a circle of four or five people around a campfire," he says. Still, he accepts that this new-found freedom to express themselves often gets people into trouble. Emails sent in a day almost exceed the number of letters mailed in a year. But more people are recognizing the content of a typical email message is not often exact. In Lancashire's opinion, email is a wonderful technology because _ . | [

mmlu_train_34482 | Did you ever look up at the moon and think you saw a man's face there? When the moon is round and full, the shadows of the moon mountains and the lines of the moon valleys sometimes seem to show a giant nose and mouth and eyes. At least, some people think so. If there were a man on the moon--instead of mountains and valleys that just look like the face of a man--what would he be like? He would not be like anyone you know. He would not be like anyone anybody knows. If the man on the moon were bothered by too much heat or cold the way Earth people are, he could not stay on the moon. The moon becomes very, very hot. It becomes as hot as boiling water. And the moon becomes very, very cold. It becomes colder than ice. Whatever part of the moon the sun shines on is hot and bright. The rest of the moon is cold and dark. If the man on the moon had to breathe to stay alive, he couldn't live on the moon because there's no air there. He'd have to carry an oxygen tank, as astronauts do. There's no food on the moon, either. Nothing grows--not even weeds(grass). If the man on the moon liked to climb mountains, he would be very happy. There are many high places there, such as the raised land around the holes, or craters , of the moon. Some of these _ are as tall as Earth's highest mountains. But if the man on the moon liked to swim, he would be unhappy. There is no water on the moon--just dust and rock. When you think of what it's like on the moon, you may wonder why it interests our scientists. One reason is that the moon is Earth's nearest neighbor--it is the easiest place in space to get to. Going back and forth between the moon and Earth, astronauts will get a lot of practice in space travel. Things learned on moon trips will be of great help to astronauts who later take long, long trips to some of the planets. Scientists are also interested in the moon because it has no air. The air that surrounds Earth cuts down the view of the scientists who look at the stars through telescopes. A telescope on the moon would give them a clearer, closer view of the stars.(words: 411) What is the reason why our scientists are interested in the moon.? | [

At one time, some people even drank blood to make them strong! When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called "blood transfusion". The blood goes from the arm of the healthy person into the arm of the sick person. But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four groups--O, A, B and AB. We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB. But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely. ks5u There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time. We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying.

mmlu_train_52227 | A new University of Graz study concludes that vegetarians are more often ill and have a lower quality of living than meat-eaters. According to the German press release, vegetarians "have cancer and heart attacks more often". The release also says that they show more psychological disorders than meat eaters. Consequently, the report writes, they are a greater burden on the health care system. According to the press release the scientists evaluated data from the Austrian Health Interview Survey (AT-HIS), which is also part of an important and valuable EU survey (European Health Interview Survey). The scientists examined a total of 1320 persons who were divided up into 4 groups . All groups were comparable with respect to gender, age, and socio-economic status. The study also accounted for smoking and physical activity. Also the BMI was within the normal range for all four groups. The only thing that really was different among the four groups was the diet. The four groups were: vegetarians, meat-eaters with lots of fruit and veggies, little meat-eaters and big meat-eaters. The press release states that the results contradict _ that meat-free diets are healthier. Vegetarians have twice as many allergies as big meat-eaters, and they showed 166% higher cancer rates . Moreover, the scientists found that vegans had a 150% higher rate of heart attacks. In total the scientists looked at 18 different chronic illnesses. Compared to the big meat-eaters, vegetarians were hit harder in 14 of the 18 illnesses. In the analysis, the University of Graz found that vegetarians were also twice as likely to suffer for anxiety or depressions than big meat-eaters. That result was confirmed by the University of Hildesheim, which found that vegetarians suffered significantly more from depressions, anxiety, psychosomatic complaints and eating disorders. The University of Graz scientists also found that vegetarians are impacted more by ilnessses and visit the doctor more frequently. Big meat-eaters were also found to have a "significantly better quality of life in all categories", the study found. The four categories examined were: physical and psychological health, social relationships and environment-related life quality. What was the difference between the four groups in the experiment? | [

mmlu_train_31224 | If you're a male and you're reading this, congratulations: you're a survivor. According to a survey, you're more than twice as likely to die of skin cancer than a woman, than nine times more likely to die of AIDS. Assuming you make it to the end of your natural term, about 78 years for men in Australia, you'll die on average five years before a woman. There're many reasons for this -- typically, men take more risks than women and are more likely to drink and smoke--but perhaps more importantly, men don't go to the doctor. "Men aren't seeing doctors as often as they should," says Dr. Gullotta. "This is particularly so for the over-40s, when diseases tend to strike." Gullotta says a healthy man should visit the doctor every year or two. For those over45, it should be at least once a year. Two months ago Gullotta saw a 50-year-old man who had delayed doing anything about his smoker's cough for a year. "When I finally saw him it had already spread and he finally died from lung cancer," he says. "Earlier detection and treatment may not have cured him, but it would have prolonged his life." According to a recent survey, 95% of women aged between 15 and early 40s see a doctor once a year, compared to 70% of men in the same age group. "A lot of men think they can never defeated," Gullotta says. "They only come in when a friend drops dead on the golf course and they think, 'Geez, if it could happen to him, ...'" Then there's the ostrich approach. "Some men are scared of what might be there and would rather not know," says Dr, Ross Cartmill. "Most men get their cars serviced more regularly than they service their bodies," Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups. Regular check-ups for men would inevitable place strain on the public purse, Cartmill says. "But prevention is cheaper in the long run than having to treat the diseases. Besides, the ultimate cost far greater; it's called premature death." Why does the author congratulate his male readers at the beginning of the passage? | [

Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes, which are otherwise calm and good-natured, sleep only 4.6 hours a day. We realized a long, long time ago that nature provides the best blueprint for invention. We've borrowed canals from beavers and reflectors from cat's eyes. Although the words "bionics" became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives don't go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, where we applied those same principles for building our first practical airplanes. To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wright's pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore seeds in an effort to apply those same motions, reversed, to a helicopter . Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic structure. On the other hand, Barney Connett's fish submarine actually looks like a fish. Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks.

mmlu_train_31433 | It was 1963, in Paris. While walking through the fruit and vegetable market Alice Waters was struck by the display of brilliant color1s, the music of farmers selling their produce, and in the middle of a great city. She felt "directly connected to the land." Chez Panisse, a Berkeley restaurant, which was founded upon Waters' ecological philosophy, has been named "The Best Restaurant in America" by both the James Beard Foundation and by Gourmet magazine, many times in the past. Only the food grown in accordance with the principles of sustainable agriculture was used in the restaurant. Menus offered nightly at Chez Panisse have consisted only of fresh ingredients, harvested in season, and purchased from local farmers. Alice Waters has successfully demonstrated how a restaurant can develop successfully while contributing to the general welfare of the farming community. Sharing a meal between the people was one of the wishes of Alice Waters as she would love her customers to know each other. In 1996, inspired by the Garden Project at the San Francisco County Jail , Waters decided to apply her principles to education. The project was first started at the Martin Luther King Middle School in Berkeley with the idea to transform some land near the school into a garden and, in the process, to teach local school children about food and agriculture. In 1999, over 120 people came to help plant the first cover crop, which prepared the field for farming by adding nutrients to the soil. The student garden staff has had several years' worth of harvest, and has started growing gardens like herb and tea. Here, agricultural practices are continually being revised and updated and every year the Schoolyard staff attends the Ecological Farming Conference in Monterey. A kitchen classroom has also been created, where students learn about main foods eaten in other parts of the world. "I believe that every child in this world needs to have a relationship with the land...to know how to nourish themselves...and to know how to connect with the community around them," says Waters. The middle school has become a model in itself. The students work the land and harvest the crops, while the cafeteria buys and prepares the produce for school lunches. This program will go a long way in teaching kids to value fresh food and their own contributions. This project is sure to inspire a national change in school curricula . In fact, many middle and high schools in California and Ohio have launched similar projects. In 1997, Alice Waters received the Humanitarian Award from the James Beard Foundation in recognition of her dedication and contribution towards environment. In 1999, the U.S. Department of Education Secretary, Richard Riley, honored her with a John H. Stanford "Education Hero" award.

And since then, it just tastes better and better to me. The first thing I noticed was the fresh tastes of the meat and vegetable. When I learned more about the food, I began to understand why it has this special feature. About 5000 years ago, China lost much of its wood because of over population and poor management of its forest. This loss was very bad for the country, of course, but it turned out to be very good for the food. Wood became very expensive and hard to get, so the Chinese had to learn how to use it better. In order to use less wood in cooking, they started to cut their meat and vegetables into small pieces before they put them in the hot oil. That way, the food cooked faster and they saved their _ .

Sunspots serve as an indicator of the sun's activity.For the past two years, sunspots have mostly been missing.Their absence, the most prolonged in nearly 100 years, has taken even seasoned sun watchers by surprise. When the number of sunspots drops at the end of each 11-year cycle, solar storms die down and all become much calmer. This "solar minimum" doesn't last long. Within a year, sunspots and solar storms begin to build toward a new crescendo, the next solar maximum. What's special about this latest cycle is that the sun is having trouble starting the next solar cycle. The sun began to calm down in late 2007, so no one expected many sunspots in 2008. They should return in 2010. Scientists have predicted that the next solar cycle could be the most active on record: more sunspots and more solar storms. However, sunspots are mostly missing now. Since the earth is in close contact with the sun, strong solar activities can bring trouble to our life. People of the 21st century rely on high-tech systems for the basics of daily life. Air travel and radio communications can be affected by strong solar activities. A big solar storm could cause 20 times more economic damage than Hurricane Katrina. What the sun will do next is beyond our ability to predict. Most astronomers think that the solar cycle will go on but at low level.

mmlu_train_9879 | Although they are an inexpensive supplier of vitamins,minerals,and high--quality protein,eggs also contain a high level of blood cholesterol ,one of the major causes of heart disease.One egg yolk,in fact,contains a little more than two--thirds of the suggested daily cholesterol limit. This knowledge has caused egg sales to drop in recent years,which in turn has brought about the development of several alternatives to eating regular eggs.One alternative is to eat substitute eggs. These egg substitutes are not real eggs, but they look somewhat like eggs when they are cooked.They have the advantage of having lower cholesterol rates,and they can be scrambled or used in baking.One disadvantage, however,is that they are not good for frying,poaching,or boiling.A second alternative to regular eggs is a new type of eggs,sometimes called"designer''eggs.These eggs are produced by hens that are fed low-fat diets consisting of ingredients such as canola oil,flax,and rice bran.In spite of their diets,however,these hens produce eggs that contain the same amount of cholesterol as regular eggs.Yet,producers of these eggs claim that eating their eggs will not raise the blood cholesterol in humans. Egg producers claim that their product has been described unfairly.They use scientific studies to back up their claim.And in tact studies on the relationship between eggs and human cholesterol levels have brought mixed results.It may be that it is not the type of egg that is the main determinant of cholesterol but the person who is eating the eggs.Some people may be more sensitive to cholesterol from food than other people.In fact,there is evidence that certain dietary fats stimulate the body's production of blood cholesterol.Consequently,while it still makes sense to limit one's intake of eggs,even designer eggs,it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol level.

According to Gabe Rothschild, Emerald Valley's mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city's lights that it darkened the light of the meteors passing overhead. "My family was so frustrated," admitted town resident Duane Cosby, "We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment." Astronomers--scientists who study stars and planets--have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it. There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats, frogs, snakes, etc. For example, outdoor lighting severely affects migrating birds. According to the International Dark-Sky Association, "100 million birds a year throughout North America die in crashes with lighted buildings and towers." Countless more animal casualties result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings. But some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase a person's chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory.

mmlu_train_39144 | SEE a cell phone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting "print" on your computer. You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape. Instead of ink, the materials the 3-D printer uses are mainly plastic, resin and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair --- the smoother and finer the object will be. This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it. Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost PS20,000 (200,000 yuan), while now they cost only about PS 1,000, according to the BBC. Taken out of the factory and introduced to more diverse and common uses, 3-D printing can create just about anything you can think of ---flutes , bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3-D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one. However, as 3-D printing becomes more commonplace, it may bring about certain problems --- such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils on your personal 3-D printer, who will visit a retail store again?" an expert in 3-D printing told Forbes News.

mmlu_train_27046 | Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets, and offer him companionship; some give protection, and some do hard work which man cannot do for himself. Dogs, which serve man in all three capacities, are found in various species in all countries of the world. The Husky can live in the cold polar regions, and the Saluki is at home in the hottest parts of Central Africa. The inhabitants of certain countries are dependent for their very lives on the camel. In the West Indies the little donkey, strong and sure-footed, carrying heavy loads even in mountainous places, is a familiar sight. Trained and tamed for many generations, domestic animals are not accustomed to roaming in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require. All domestic animals need proper food. It must be suitable for them, sufficient in quantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps , and then wonder why the animal seems tired and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health. Even well cared for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price. Useful, friendly, hardworking animals deserve to have some time, money and attention spent on their health. To keep a domestic animal physically fit, its owner is advised _ . | [

mmlu_train_52445 | For a long time, people who fish have had to rely on luck to catch fish. Even big fishing ships, fitted out with radar and modern equipment, have their share of bad days. Wouldn't it be nice if fish could be trained to come at the call of a whistle the way some days are trained? Well, the days of "fish whistle" may be just _ . Japanese companies are working on methods that will train fish to return to harvest areas at the sound of an underwater whistle. The method works like this: First, fish eggs are hatched in a laboratory. Whenever feeding time arrives, a whistle sounds. The young fish learn to return to their feeding areas at the sound of the whistle. Later, the fish are set free at sea, near special-made under water "barns". There, the whistle-plus-feeding program continues. Being well fed and sheltered, the fish continue to live around the barn. So when fishing time arrives, all the harvesters need to do is to sound the whistle, drop their nets, and draw in a lot of fish. Many countries have closed their offshore fishing waters to ships from other countries. With fish whistle and barns, Japan hopes to become less dependent on importing fish from other countries. From the passage we learn that _ . | [

mmlu_train_32761 | Lights Out at Bedtime There are plenty of good reasons to power up a personal desktop or laptop computer in the evening -- writing e-mails,chatting on social networks or making purchases over the Internet,for instance.But various studies indicate that people who stare at a PC's bright monitor shortly before going to bed probably sleep less soundly than they would otherwise because the light seriously affects their natural wake-sleep cycle."They haven't proved it though," says Dieter Kunz,the team's director at Charite's Psychiatric Clinic in St.Hedwig's Hospital in Berlin. Similarly,exposure to just 10 minutes of normal bathroom lighting is enough to free the sleep hormone melatonin,which regulates people's natural wake-sleep cycle and makes them sleepy at nightfall. Ten years ago,a team of British and American researchers detected a photo-pigment in the human eye that signals to the body whether it is day or night,summer or winter.The photo-pigment is especially sensitive to blue light. "The blue light more or less tells the body,'It's daytime,be awake,'" Kunz says.Monitors have a mostly cold white light content and scientists suspect the photo-pigment may react similarly to it.So the longer people look into the bright light,the more awake they become - and then sleep poorly. A lot of people have difficulty "switching off" in the evening.About half of the women in Germany and a quarter of the men sleep poorly. Environmental factors are only one of the possible causes.Job stress as well as personal and health concerns are also the main reasons for their sleep problems. In addition,electronic objects' standby lights and indicator lamps can be annoying in the dark and affect sleep."Sound scientific evidence is still lacking on this matter," Kunz notes. According to Kunz,those who cannot go without their computer in the evening should turn down the blue content if possible and lower the brightness somewhat."But nobody does that because,after all,you want to concentrate while working at the computer and the light helps the brain."

The walk to school would be very, very easy. Such _ clothing is one of the products that could be created using "wearable robotics" technology. Designed to improve a person's senses and skills, the device could be as simple as a hearing aid. Or it could be a full-body suit that senses what you're going to do, then helps you do it better. "A superman suit would be the final result in wearable robot i cs ",s a id Francois Pin, head of robotics and energy systems at the Oak Ridge National Laboratory , US. While these suits are at least ten years away, in some areas the technology is already in use. Researchers are developing artificial- arms and legs that allow old,disabled or injured people to move freely. Thus US Army is interested in using wearable robot legs to help soldiers run faster, carry more equipment and be stronger in battle. Jobs that involve lifting heavy loads or saving lives from the rubble of an earthquake could also become much easier. A robot is a device that responds to a command. You're probably with simple robots, such as toy cars or airplanes that respond to buttons you push on a remote control. Wearable robotics goes further. Instead of just receiving information through a wire or remotecontrol- the robotic device can send information back to its controller. Suppose you wore a sleeve that has sensors where your joints are. Every time you move your arm, the sleeve senses your movements and sends the information to a robot, which then moves its arm just as you did. When the robot hits or touches something, it sends a signal back to the sleeve and you sense the action. In this way,scientists are working to wrap the robot around the person. Their goal is to make the sleeve, shoe or suit help you do what you want to do. From the passage, we can infer that _ . | [

mmlu_train_11838 | Is losing weight as simple as doing a 15-minute writing exercise? In a new study, women who wrote about their most important values, like close relationships or religion, lost more weight over the next few months than women who didn't. "We have this need to feel self-integrity (,)," says Christine Logel of the University of Waterloo. "When something threatens your sense that you're a good person, like failing a test, we can buffer that self-integrity by reminding ourselves how much we love our children, for example". For this study, the researchers recruited 45 female undergraduates, of whom 58% were overweight. Each woman was weighed, and was then given a list ofimportant values, like creativity, music or relationships with friends and family members. Each woman ranked the values in order of how important they were to her. Then half the women were told to write for 15 minutes about the value that was most important to her. The other half, a control group, were told to write about why a value far down on their list might be important to someone else. The women came back months later to be weighed again. Women who had written about an important value lost an average of 3.41 pounds, while women in the control group gained an average of 2.76 pounds. "How we feel about ourselves can have a big effect," Logel says. Maybe when one of the women who wrote about an important value went home that night, she felt good about herself and didn't eat to make herself feel better. Over a few months, that could make a real difference in her life, Which of the following persons may lose weight according to the new study? | [

mmlu_train_62084 | While the history of technology can be traced along many lines, one of the most amazing development is that of photo technology, the technology of light.From the prehistoric invention of fire to laser beams and fiber optics , light has "continually occupied the minds of inventors".Their inventions fall into two groups: the use of light to help us see better and more interestingly, the use of light for purposes of communication. The use of light for communicating is one of the major directions that technology has taken ever since the middle of the nineteenth century.From still photography to motion pictures to television (with a development from black - and - white to color1 imagery in each), photo technology has had a great effect upon mass communication and mass education.Unlike the printed words, visual images have more impact because they are more immediate.They copy reality in a way that the printed words cannot.Unlike letter shapes, they are not abstract; unlike words, they require no symbolic interpretation by the mind.Combined with the widespread and uniform spreading of such images, photo technology affects the thinking of vast audiences and shapes their view of reality. Millions of Americans are affected by the commercially - inspired electronic manipulation of artificial images.We call it "entertainment" and can't wait to get more. As the number of commercially available television channels grows, the viewer's freedom of choice increases, but so does the burden of that choice.Increasingly he is faced with a sea of in formation and is asked to make quick choices. More significantly, the ease and rapidity of mass communication has created a supply of information greater than it can readily be absorbed.Flooded in the sea of information, the individual struggles to swim through it.

mmlu_train_6706 | Height is just one of the thousands of features your genes decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you're going to be, ask your doctor if he or she can help you find it out. But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your ideal height. Getting plenty of sleep and enough exercise will help you grow to the expected height. No doubt you're wondering how fast you should grow. It depends. There's no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up). Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you're at now, how you've been growing up to this point, and what other changes your body may be going through. Don't be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later ---between 7 and 13 for girls and 9 and 15 for boys. You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty. After reading this passage, we can explain _ . | [

mmlu_train_31075 | Ocean animals have been getting bigger over the last half-billion years. Not a little bigger. Not even a lot bigger. They have _ gigantically, scientists now conclude. Their new finding lends support for something known as "Cope's rule." It holds that animals tend to evolve into species that are much larger than their distant ancestors. This hypothesis takes its name from the 19thcentury paleontologist Edward Drinker Cope. While studying fossils , he was the first to notice this trend. Noel Heim is a paleontologist at Stanford University in Palo Alto, Calif. He also is a co-author of the new study. His team compared the body size of animals between the Cambrian Period and modern times. This was a span of 542 million years. The animals studied included species from more than 17,000 genera. They ranged from ancient trilobites, plesiosaurs (extinct reptiles with a long neck and flippers) and many less familiar creatures to today's whales and clams. Ocean animals today are an average of 150 times larger than they were during the Cambrian, Heim's group reports. The smallest animals alive today -- tiny crustaceans called ostracods -- are only about one-tenth the size of the Cambrian's tiniest animals. But today's largest ocean animals -- whales -- are more than 100,000 times bigger than the biggest in the Cambrian. "Classes of animals that were already big ... tended to live longer," Heim says. They also tended to change more than classes of animals that were small did. The size gains in ocean animals are much larger than would be expected by chance, saysJonathan Payne. He's a co-author who also works at Stanford. The scientists don't know what drives the trend. One possibility is an arms race between predators and prey. The idea here is that larger animals are less likely to become some other animals' meal. Another possibility has to do with oxygen. Land animals evolved from species that started in the ocean. Some of these land animals eventually returned to the ocean. And they kept the ability to breathe oxygen-rich air. That may have made it easier for them to outgrow animals that had to filter their oxygen out of the water. The ocean animals' change in size _ . | [

But now there are more reasons than ever for people to reach for a slice of watermelon. Meet Dr Alison Edwards. She is a scientist at the Agricultural Research Service. Scientists are people who come up with new ideas called theories . They usually do scientific research to test their new theories.

mmlu_train_9343 | Many gardeners believe that "talking" to their plants helps them grow---it turns out that _ may not be crazy after all. According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret "unseen" language. For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the protein---luciderase , which is what makes fireflies glow in the dark. When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciderase, they could see the plant sending out "methyl jasmonate ". While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbage plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep predators like caterpillars away. What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the danger---something that will require further research However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other. However, before you get all concerned, they are quite sure that plants do not feel the pain when they are cut, since they do not have nerves---so go ahead and bite into that juicy carrot!

Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down? In the battle against cheating, this is the _ and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven't just searched the Internet to get the right answers. Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance. Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students' identities using personal information, such as the telephone number they once used. Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones.

mmlu_train_30080 | The earth is not the only body that travels around the sun. With it are eight other planets, fellow members of the sun's family. Two of them, Mercury and Venus, are nearer while the other six, namely Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, also in their given order from the sun, are farther from the sun than the earth is. The farther they are, the longer trips they make around the sun. People noticed long ago that these traveling bodies moved around in the sky in definite paths. It is a force called gravity that holds them in their paths. We know that every little bit of matter in the universe pulls upon every other bit of matter. The pull between two bodies is proportional to the product of their masses. Because the sun is so large the pull between the sun and the planets are thus great. If it were not for this pull, the planets would fly off into space. In the same way there exists a pull between the earth and the moon, which keeps the moon traveling in its orbit around our planet, the earth. Gravity holds you to its surface, and pulls back to it the ball which you throw into the air. Of course the ball also pulls on the larger earth but the earth is so much larger that the pull is not noticed. Now remember that large bodies exert a greater pull than smaller ones which contain less material. But each object in the universe, no matter how small, pulls on all other objects to some degree.
