mmlu_train_33961 | Whether you're taking a trip alone or with your family, it's easier to get sick when you're in a new place because your body hasn't had a chance to _ to the food, water, and air in a new environment. Read the following tips on keeping your travel experience as healthy as possible. Safe foods and drinks What foods are safe to eat? Foods that have been boiled are generally safe, as well as fruits and vegetables that have to be peeled before eating. Avoid eating uncooked or undercooked meat. Stay away from foods that require a lot of handling before serving. Drink only bottled water when traveling. If you have to use the tap water, you should boil it first. You can take it with you When you're packing, taking some painkiller and diarrhea medicine is a good idea. It's also a good idea to pack some allergy medicine even if you don't take it at home, because people sometimes unexpectedly develop allergic reactions in a new environment. Write it all down Before you leave your sweet home, create a medical history form that includes the following information: your name, address, and home phone number as well as a parent's daytime phone number your blood type a list of any ongoing health problems, such as heart disease, diabetes, or AIDS a list of current medicines you are taking a list of allergies to medicine, food, insects, and animals the name, address, and phone number of a relative other than your parent It also helps if you have some basic emergency medical knowledge, not only for yourself but also for helping others you may be traveling with. A great way to prepare for your trip is to take a first-aid or basic life support course before you go; if you're traveling with a group, you should know where the first-aid kit is and what's in it.

mmlu_train_7343 | Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a _ . At first, Eijkman thought some kind of germ caused beri-beri. He raised some chickens. He didn't eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate -- refined white rice . When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery -- that some things in food could prevent disease. These things were named vitamins . The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person's food. Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don't, they can also take vitamin pills.

mmlu_train_41968 | Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which reduces strength and increases the possibility of falls and fractures . New research is showing how this happens and what to do about it. A team of Nottingham researchers has already shown that when older people eat, they cannot make muscle as fast as the young. Now they've found that the ability to prevent muscle breakdown is reduced with age. When older people eat, they don't build enough muscle with the protein in food; also, the insulin fails to shut down the muscle breakdown that rises between meals and overnight. Normally, in young people, insulin acts to slow muscle breakdown. The research just published compared one group of people in their late 60s to a group of 25-year-olds, with equal numbers of men and women. "We studied our subjects first -- before breakfast -- and then after giving them a small amount of insulin to raise the hormone to what they would be if they had eaten breakfast," Professor Rennie said. " The results were clear. The younger people's muscles were able to use insulin we gave to stop the muscle breakdown, which had increased during the night. The muscles in the older people could not. In the course of our tests, we also noticed that the blood flow in the leg was greater in the younger people than the older ones," added Professor Rennie. However, scientists think that weight training may reactivate muscle blood flow and help retain muscles for older people. "In fact, doing exercise three times a week over 20 weeks reactivates the leg blood flow responses of older people. They became identical to those in the young," said Professor Rennie. Which of the following is TRUE according to the passage? | [

mmlu_train_9885 | Monkeys prefer heavy metal to classical music, according to researchers at the University of Wisconsin whose findings are published this week in Biology Letters. Scientists played a selection of music to a group of South American cotton-top monkeys but the only sound that got a reaction were from the heavy metal band Metallica. They were seemingly disinterested in Led Zeppelin, Miles Davis and Bach, but after the beautiful sound of Master of Puppets by Metallica was played the monkeys calmed down. "Monkeys interpret rising and falling sounds differently than humans. Oddly, their only response to several samples of human music was a calming response to the heavy-metal band Metallica," said Professor Charles Snowdon, from the University of Wisconsin-Madison. Rather than making them excited or aggressive, the heavy metal tracks had a comforting effect. Dr Snowdon, who teamed up with National Symphony Orchestra musican David Teie, also played the monkeys music composed specifically for them. Although they enjoyed Metallica, they were much more interested in these pieces. A melody based on the short calls of scared monkeys led to anxiety levels rapidly growing, researchers found, while one based on long calls the creatures make when they are happy had a calming effect. Frans B.M. de Waal, a professor of psychology at Emory University who studies animals, said the findings appear to say more about how monkeys respond to the sounds they make than they do about music or the evolution of music. Dr Snowdon no longer has a monkey colony to use in his research, but he said his co-author David Teie is exploring the concept of music for cats. "If we understand how we can affect their emotional states through using musical sound and aspects of our speech, maybe those of us living with companion animals can have a better relationship with them, too," Snowdon said. The aim of the research, according to Professor Snowdon, is to _ . | [

mmlu_train_62609 | Everyone who has eaten instant noodles before knows how it looks like. It is very easy to cook it instantly by putting the noodles into the boiling water and add in those MSG packets, together with your other ingredients like eggs or vegetables. However, have you ever wondered whether this is the correct way of cooking it? When you first took out the noodles from the packaging, you will notice that the noodles are joined together nicely as a piece. In order to make the noodles joined together nicely side by side, it needs some form of wax coating to achieve an attractive instant noodles in front of us. Many people who enjoy eating instant noodles frequently do not really bother too much of it, as it seems very normal to everyone to have it nicely displayed in front of us. However, researches have shown that the layer of wax coating on the noodles is quite harmful to our body and we should not eat it too frequently. It is advisable to have a break of 2-3 days before we start to eat another packet of instant noodles as our body need about 3 days to clear that layer of wax coating away from our body system. Do you know the danger of having too much wax coating stored in our stomach? It will lead to CANCER if it is stored in our body system for a long period of time. There are 2 keys points to take note while preparing instant noodles: 1) Wash the instant noodles with warm water first, stir it and pour away the water containing the wax coating. 2) Repeat Step 1 and try to stir the noodles again to wash away the wax coating on the noodles before cooking it in a new pot of water.

mmlu_train_19676 | "I don't want to buy a traditional yearbook. I can keep and share memories of my high school on the Internet."You may often hear this from many American high school students now. Instead of buying a book, more and more students choose to sign up at My Yearbook.com. My Yearbook.com was created by two teenagers, Catherine Cook and her brother, 18-year-old David Cook, in 2005. They built it up to about 950,000 members in a year. The site allows people to create a profile with separate sections for high school, college, graduate school and professional life. Students who sign up are linked to other people at their school. Acting as their own editors, they can select friends from their classmates. The site also connects students through clubs and spprts pages. Like other so-called social-networking sites, it allows members to show photos and post messages. Students can do lots of things that old-fashioned yearbooks can't offer, including hearing music and watching videos. Catherine and David developed the idea because they thought that their own yearbooks weren't good enough and were too expensive. "We just think yearbooks are obsolete," said Catherine Cook, 16."If you think about it, all you're going to do with it is put it on the shelf and never really look at it." Many American teenagers want different things out of their yearbooks than their parents did. They like the idea of creating an online yearbook. That is the reason why My Yearbook.com is becoming more and more popular. Some people, however, still wonder if this free website can ever truly replace the traditional printed book of high-school memories-even for the generation that have grown up with the Internet.

mmlu_train_88457 | Do you like to eat sushi ? Many people are afraid to eat it, because they think the bacteria in it might make them sick. However, a new study shows that sea bacteria are good for people. The study finds that a special enzyme from sea bacteria is helpful to humans. It helps people to get more energy from food. To people's surprise, the enzyme is present only in the Japanese. The Japanese traditionally like to eat food rich in seaweed . And the seaweed is rich in this kind of enzyme. However, the enzyme isn't present in all the Japanese. During the study, just 5 out of 14 Japanese had the enzyme. All the Americans studied didn't have the enzyme. "The number is small," said researcher Mirjam Czjzek. "But we can say that this enzyme is present only in the Japanese and not in the North Americans." Then some people think that maybe other people are able to get the enzyme if they eat a lot of seaweed. The study suggests that they collect uncooked seaweed to make their sushi. Restaurant sushi is often cooked, which will destroy the enzyme. So, if you want to get that enzyme, you can travel to Japan to have a taste of the real sushi.

mmlu_train_48823 | Federal regulators Wednesday approved a plan to create a nationwide emergency alert system using text messages delivered to cell phones. Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates more than 48 billions text messages are sent each month. The plan comes from the Warning alert and Response Network Act, a 2006 federal law that requires improvement to the nation's emergency alter system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies. "The ability to deliver accurate and timely warning and alert alters through cell phone and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan. Participation in the alert system by carriers -- telecommunication companies -- is voluntary, but it has received solid support from the wireless industry. The program would be optional for cell phone users. They also may not be charged for receiving alerts. There would be three types of messages, according to the rules. The first would be a national alter from the president, likely involving a terrorists attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction emergencies, or so-called Amber Alerts. The service could be in place by 2010. The carriers' participation in the system is determined by _ . | [

mmlu_train_70139 | Many students are under great pressure this term. There is some advice on studying and preparing for exams. Sciences Ask students what is the most difficult course, and most of them will give you the same answer: mathematics. This is also true for Dai Shuang, a 14-year-old student at No.1 Middle School. He says, "It's so difficult that I get a headache whenever I think about the math exam." According to Dai, studying this course is not easy. He usually studies math by himself and spends most of his free time reading math books and doing exercises. _ Qin Xia, a math teacher, offers some advice. "Most students fear mathematics because they think the class is too difficult or boring." he says, "These students don't listen carefully in classes or even sleep." In Qin's opinion, they can try to take notes. And they'd better ask teachers for help. It's difficult for students to teach themselves math, which will waste a lot of time.

mmlu_train_64538 | We've all seen them: perfectly toned famous people on late-night television telling us that we too can develop rock-hard abdominal muscles . It's easy! Just pay $149.99 for the Torso Track or $149.75 for the Ad-Doer and watch those unwanted inches leave your waist. Americans spend tens of millions of dollars on various products to firm up their fat around the waist. And did they work? Not necessarily. Independent studies have concluded that most of these products -- no matter who approved them or how expensive they are -- shape your midsection no better than old-fashioned stomach crunches . Some can even cause injury -- like the $518.99 Body Shaper-Q8SP, which left electrical burns on some researchers at the University of Wisconsin, La Crosse. Others, like the popular Ab-Doer, typically burn less energy than a gentle walk, according to a study to be published in September by the American Council on Exercise. The fact is that many Americans don't have the biological makeup to develop an obvious abdominal muscles. They are either unable to get the necessary muscle mass or they can't lose enough fat to make a difference. Even if the underlying muscles are well developed, all it takes to hide it is one-sixteenth of an inch of fat. That's enough to exclude most healthy women as well as plenty of guys who do crunches every day. So what works best? In its new study, the exercise experts researched on the results of the popular Ab-Doer. A lengthy TV advertisement promises that just 10 minutes a day performing such movements as "Body Boogies" and "Good Mornings" will "help form those muscles the fun and easy way without diets." Steven Loy, professor at California State University, Northridge, tested the promise by measuring the electrical activity produced by the abdominal muscles during three Ab-Doer movements. He and his colleagues then compared the results with those produced during traditional exercises. They determined that the muscles were no more active, and in some cases less so, when exercisers were using the Ab-Doer. Taking a broader approach, researchers at San Diego State University compared 13 abdominal exercises for their ability to develop the central abdominal muscles. They concluded, in a report published in May, that the most effective exercises kept turning the body and worked the muscles the entire time. Among the winners: the bicycle movements -- so called because it looks as if you are riding a bike while lying flat on the floor -- and exercises performed on the "Captain's Chair", a product typically found in gyms that helps hold the body in the air while you raise your legs up toward your chest. Researchers suggested that a varied routine of the different exercises could deliver the best results. Which of the following is the most effective in building abdominal muscles? | [

mmlu_train_40567 | Everywhere man is altering the balance of nature.He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously.He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization.He exterminates some species on a large scale, but favours the multiplication of others.In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million. Many of these changes which he has brought about have had unforeseen consequences.Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers' wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece?

mmlu_train_43505 | While most travelers aim to stay out of the hospital while on vacation, a growing number of medical tourists-people who combine treatment with travel - are crossing international borders for the purpose of getting medical services, which can range from a hip replacement to a tummy tuck. Widespread air travel, increasing healthcare costs in developed countries, long waiting lists and an ageing world population have all contributed to a global increase in medical tourism in the past decade. And Asia takes the lead in terms of world market share. More than 89% of medical tourists travelled to Thailand, India or Singapore in 2010, with Bangkok and Singapore leading the pack. But the cost of hotel rooms and treatment are both far more expensive in Singapore than in the Thai capital, making Bangkok the most popular place for medical tourism in the world. Even after the serious floods of 2011, 19 million tourists visited Thailand in 2011, a 20% jump from 2010, with about 500,000 tourists travelling specifically for medical treatment. Given Thailand's reputation for outstanding service, it is not hard to see why Bangkok has quickly become the medical tourism centre of Asia. The Tourism Authority of Thailand(TAT), which began medical tourism in 2004, has a detailed medical tourism website that lists many of the most popular treatments available, including dental work, dermatology and cosmetic surgery, as well as listing reputed hospitals, making it easy for potential visitors to decide on a procedure. TAT has also recently partnered with Krungthai Bank, the national bank of Thailand, to offer tourists a card called the Miracle Thailand Card, which offers some medical and life insurance coverage in case of an accident. "The hospitals in Bangkok are some of the highest quality in the world,meeting US standards,"said Steven Lash, CEO of a US-based medical travel company that sends tourists to Bangkok as well as to seven other countries, including Turkey and Mexico.

mmlu_train_64572 | The biggest danger facing airlines nowadays may not be a terrorist with a gun, but the man with portable computer in business class. In the last 16 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference . The source of this interference remains not proved, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones. RTC.A. an organization which advises the aviation ( )industry, has suggested that all airlines ban such devices from being used during "critical" stages of flight particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently , rules on using these devices are left up to individual airlines. And although some air- lines prevent passengers from using such equipment during take-off and landing, most are unwilling to carry out a total ban, given that many passengers want to work during flight. The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices send out radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not. The fact that aircraft may be fragile to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying,though, is the passenger who can 't hear the instructions to turn off his radio because the music's too loud.

mmlu_train_40682 | We must do what we can to protect the plants because plants are very important for living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us. If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are _ by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores . Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants. This passage may be taken from _ . | [

mmlu_train_62674 | American children are not the only couch potatoes with nearly one third of children globally spending 3 hours a day or more watching TV or on computers, according to the study of over 70,000 teens in 34 nations. From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children were not getting enough exercise and that it made no difference whether they live in a rich or a poor country. "With regards to physical levels, we didn't find much of a difference between rich and poor countries," Guthold said, "Growing up in a poor country doesn't necessarily mean kids get more physical activities." The researchers defined adequate physical activity as at least an hour of exercise outdoors for at least 5 days a week. Children spending 3 or more hours a day watching TV, playing computer games or chatting with friends were classified as sedentary. The researchers found only a quarter of the boys and 15 percent of the girls were getting enough exercise by these definitions. A quarter of boys and nearly 30% of girls were sedentary and didn't get enough exercise with girls less active than boys in every country aside from Zambia. Girls from India were the most active with 37 percent meeting exercise recommendation, while girls from Egypt were the least active with 4 percent getting enough exercise. Children in Myanmar were the least sedentary while the most sedentary nations were St .Lucia and the Cayman Islands. People show deep concern for kids' lack of physical activity in various nations. Why do they have a low level of physical activity? Guthold speculated that urbanization could be a factor as well as easy access to cars and TVs.

mmlu_train_18534 | Motherhood may make women smarter and may help prevent dementia in old age by bathing the brain in protective hormones , U.S.researchers reported on Thursday. Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer's .University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans."Our research shows that the hormones of pregnancy are protecting the brain, including estrogen , which we know has many neuroprotective effects," Kinsley said. "It's rat data but humans are mammals just like these animals are mammals," he added in a telephone interview."They go through pregnancy and hormonal changes." Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer's and other forms of age-related brain decline. "When people think about pregnancy, they think about what happens to babies and the mother from the neck down," said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida. "They do not realize that hormones are washing on the brain.If you look at female animals that have never gone through pregnancy, they act differently toward young.But if she goes through pregnancy, she will sacrifice her life for her infant--that is a great change in her behavior that showed in genetic alterations to the brain."

mmlu_train_43069 | Millions of young people are writing blogs . Millions of others are reading them. The word "blog" is a short way of saying Web log. Many popular Web sites now offer free, easy ways to create personal Web pages and fill them with writings and pictures. Web sites called "Face book" and "My Space" are some of the most popular blog sites for young people. Blogs offer young people a place to show their writings and feelings. They can also be helpful to connect young people with others. But blogs can become dangerous when they are read on the Internet by millions of people all over the world. Recent studies show that young people often tell their names, age and where they live on the Internet. That may not be safe for them. This personal information puts them in danger when found out by dangerous people who want to hurt them. Students can also get into trouble when they put information about others on their blogs. As a result, many schools don't allow using blogging web sites on school computers. Many schools have also begun teaching parents about the web sites. Parents should know what their children are doing online and should read their blogs to make sure they are not giving out personal information.

However,some players complained right away that the new balls bounced differently and were actually harder to control than the leather ones. Physics helped answer questions about why the new balls felt different.For example,the scientists studied friction ,which in this case affects the ability of a player to hold onto a ball."The greater the friction,the better it will stick to his hand,"explains a scientist. Tests on both wet and dry balls showed that while the synthetic ball was easier to hold onto when dry,it had less friction and became much harder to hold onto when wet.That's because _ stays on the surface of the synthetic balls but gets taken into the leather balls. The scientists also tested bounce and found that the logo printed on the new balls made their surface uneven and caused them to bounce a little strangely com- pared with the leather balls. In January,the NBA went back to using the leather balls.They aren't perfect,but for now,that's just the way the ball bounces. The ball is easier to hold on to _ | [

mmlu_train_56191 | Dolphins call out the specific names of loved ones when they become separated, a study finds. Other than humans, they are the only animals known to do this, according to the study. The big difference with dolphins is that these communications consist of whistles , not words. Earlier research found that dolphins have a "signature whistle" that would be somewhat like human shouting, "Hey everybody! I'm an adult healthy male named George, and I mean you no harm. " The new finding is that dolphins also say the names of certain other dolphins. "Animals produced copies of the same sound when they were separated from a close partner. This supports our belief that dolphins copy another animal's signature whistle when they want to reunite with that animal," Stephanie King, who led the study, says. King and her colleagues collected acoustic data from wild dolphins around Sarasota Bay, Florida, from 1984 to 2009. The researchers also studied four adult male dolphins _ at the Seas Aquarium, also in Florida. Those males are adults that keepers named Calvin, Khyber, Malabar and Ranier, all of whom, as well as all of the wild ones, developed their own signature whistles that served as names in communication with other dolphins. "A dolphin uses its signature whistle to broadcast its identity and announce its presence. The signature whistles allow animals to identify one another over long distances and allow animals to recognize one another and to join up with each other," King explains. "Dolphin whistles can be heard up to 20km away, depending on water depth and whistle frequency ." The researchers said dolphins copy the signature whistles of loved ones, such as a mother, when the two are separated. These "names" are always used in positive situations, and are only directed toward loved ones. While researchers are often unwilling to apply the word language to non-human communications, dolphins clearly have a very complex communication system.

If you stand some distance away from the starter, you can see smoke from his gun before the sound reaches your ears. This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight's stars had started on its journey to you before you were born. Thus, if we want to be honest, we can't say, "The stars are shining tonight."

mmlu_train_67049 | You know that balloons must be kept away from sharp objects. They also needed to be kept away from flames. A fire can weaken the rubber and cause it to break. However, in this experiment you will find out how you can hold a balloon directly in a flame without breaking the balloon. Materials needed: * two round balloons not inflated * several matches * water Inflate one of the balloons and tie it. Place 1/4 cup of water in the other balloon, and then inflate it and tie it. Light a match and hold it under the first balloon. Allow the flame to touch the balloon. What happens? The balloon breaks, perhaps even before the flame touches it. Light another match. Hold it directly under the water in the second balloon. Allow the flame to touch the balloon. What happens to this balloon? It doesn't break. Why does the balloon with no water break in the flame? The flame heats the rubber of both balloons. The rubber of the balloon without water becomes so hot that it becomes too weak to _ the pressure of the air inside the balloon. However, when the balloon with water in it is placed in the flame, the water takes in most of the heat from the flame. Then, the rubber of the balloon doesn't become very hot, it doesn't weaken, and the balloon doesn't break. Water is a particularly good absorber of heat. It takes a lot of heat to change the temperature of water. On the other hand, when water cools, it gives off a great deal of heat. That's why areas near oceans or other large bodies of water don't get as cold in winter as areas at the same latitude further inland.

The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artist-naturalists, Leopold Blaschka and his son Rudolph. The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed.

mmlu_train_11638 | Some people in Manchester, Britain, will soon be paying for goods and services with so-called "smart" credit cards. These cards are more secure than the traditional magnetic-strip version and can be used to travel on buses, check bank accounts and do shopping. The Manchester project is one of the biggest smart card schemes in the world. Every time people use the cards on a bus or train, the fare is deducted (reduced) from the value of the card. When they have no credit left, the cards can be recharged at a local shop. A smart card looks just like a normal plastic card but it has a silicon chip in it. It is possible for the same silicon chip to perform a number of different functions, so one plastic card in your pocket could do a large number of different jobs. The card has much more memory space than a magnetic-strip card, so many more things can be recorded on it.There are two types of smart cards. One is the contact card which is used in the same way as a magnetic-strip card. Information is transferred by running the card through a narrow opening in an electronic reader. In the slot, electronic probes make contact with the magnetic-strip or silicon ship and read the information. The other type is the contactless smart card where the electronic reader communicates with the card by short-range radio waves. This makes the card quicker and more convenient to use because it does not have to leave your wallet. It is also more reliable as it is not easily influenced by scratches or dirt. However, the biggest advantage that smart cards have over magnetic-strip cards is that they are more secure. They are much more difficult to make than conventional cards and they have to be made by specially trained manufacturers. In addition, they have a large number of extra security features on them and if a smart card gets lost or stolen a quick phone-call to the distributor ensures that its individual number is made invalid and unreadable. This can be done more quickly than with a magnetic-strip card. Which of the following statements is TRUE according to the passage? | [
"Contactless cards are more convenient to use than contact ones",

mmlu_train_40857 | Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes , Thomas would need to inject himself with insulin three times a day for the rest of his life or risk nerve damage, blindness, and even death. And if that weren't bad enough, he had no health insurance. After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar , and created diabeticrockstar.com, a free online community for diabetics and their loved ones--a place where over 1,100 people share personal stories, information, and resources. Jason Swencki"s son, Kody, was diagnosed with type diabetes at six. Father and son visit the online children's forums together most evenings. "Kody gets so excited, writing to kids from all over," says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone." Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages. These days, Thomas's main focus is his charity, Fight It, which provides medicines and supplies to people--225 to date--who can't afford a diabetic's huge expenses. Fight-it.org has raised about $23,000--in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean. Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables.

mmlu_train_58210 | Some weight-loss camps, which are rare in China just a few years ago, have sprouted in Beijing, Qingdao, Shenzhen, and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight. Of these, 90 million--about 7 percent--are obese . Experts say the obesity epidemic is spreading to children, though more slowly than in adults. The trend, they say, will have a huge impact on the health of China's citizens and economy. "We're seeing a very large proportion of children and adolescents who are quite heavy and aren't moving much," said Barry Popkin, a nutrition professor. Popkin carries out an ongoing health-and-nutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight "quite quickly". In just ten years China's childhood obesity rate has doubled, with the greatest gains coming in urban areas. "In big cities it's a big problem." Some experts blame the extra fat on a range of factors, many of them tied to China's rapidly changing economy and culture. The diets of Chinese adults and children are far higher in calorie-laden meats, fish, eggs, dairy products, fats, and sugars than ever before. In addition, kids--especially city dwellers--are more sedentary today and spend more time indoors in front of homework, television, computer games, and the Internet. Shuwen Ng, a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids' food choices. Certain foods, such as new candies or fast food, have attractive features. China's childhood obesity rate still lags that of the United States, where some 15 percent of kids are said to be obese. But the long-term effects are equally serious. What's the best title for the passage? | [

mmlu_train_12985 | A micro blog with space for 140 Chinese characters had once been a source of endless amusement for Wang Ganghui, a senior majoring in biochemistry at Ji'nan University. Until last month, the 21-year-old Wang had believed that he was part of a broader movement. Recently, however, Wang's micro blog is silent. The reason? It's because of a woman known as "Zhao Meimei". Earlier this month, Wang joined many other users to criticize the US-based student for her wealthy overseas life, because they thought her money came from _ since her mother was a local official. But later Wang found out that the woman student was actually being supported by her father, a hard-working businessman. "I felt guilty... Someone hid part of the truth to make a conflict. The worst thing is - I did not even have a chance to apologize to her," he says. Wang is not the only young Internet user to be confused by an online world made up entirely of broken information. According to official statistics, the number of micro bloggers in China now exceed 300 million. For private users, a micro blog can provide real-time updates from anyone a user chooses to "follow". These can range from family members to celebrities . Information can instantly be spread through "re-tweeting". In the public area, however, a micro blog can also become a link between users and the authorities. However, with the increasing popularity of micro blogs comes a number of problems. Chen Changfeng, deputy director of the School of Journalism and Communication at Tsinghua University, stressed two major types of misbehavior that can occur on micro blogs and upset young users. "Some marketers spread fake news just to make some person or product known to more people; others use the free channel to manufacture and spread fake news and rumors like a virus," Chen says. He says that an average micro blogger receives and transmits information, but when faced with such a vast amount of information, he may lack the ability to tell the difference between the real and the fake stories. Having realized this, Internet users have come together to combat micro blog misconduct by forming voluntary groups such as the Rumor Clarification Association. The government and individual operators of micro-blogging sites have also stepped into monitor posted content. From the passage we can conclude that _ . | [

mmlu_train_45371 | Suppose you are reading a book. Suppose, too, you suddenly close your eyes. Can you still see the book? "Of course not," you will say. But can you tell why? You would probably say, "When I close my eyes my eyesight cannot get out of my eyes to get to the book. " But this explanation is wrong. You cannot see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples of that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous body. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in your direction. So moonlight is only second-hand sunlight. When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open. Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380,000 kilometres away, in only a little more than a second. Which one is true? | [

It is an invitation-only conference aimed at finding new ways to deal with old problems. Traffic jam is a problem that Bruggemann hopes to solve."Traffic is really bad in most countries and we thought there must be some way of doing something about it."Last week, his team, winning the prize for its"nunav"traffic management system, received a Microsoft Imagine Cup Grant of $100,000."Everyone that's using our system sends his present position as well as the destination to our servers every 30 seconds. And with that information our central system can reroute all of the cars in a way that everyone gets his individual best possible route." Bruggemann says early research with the system has been promising."We found out that it could be possible to save up to 20 percent of the fuel consumption. Even more interesting, it can save up to 50 percent of the time you spend in traffic so you could get to your destination twice as fast." Team Cypher256 from Uganda also was invited to the Social Innovation Summit. They developed a device ,called WinSenga, aimed at improving health care for pregnant women in Africa. It measures the early baby's heart sounds to help test the heart rate, age and position of the baby in the mother. The device is similar in operation to an ultrasound test, but is far less costly and very practical in Africa. This is the third year for the Social Innovation Summit.

mmlu_train_56476 | We've heard about radiation from the damaged nuclear reactors in Japan reaching American shores. Experts say so far there is no reason to worry, and point out that we meet radiation every day. Where and how? NPR's Renee Montagne posed that question to Peter Caracappa, a radiation safety officer and professor of nuclear engineering. MONTAGNE: How many things emit radiation? Dr CARACAPPA: Well, radiation and radioactive material is a part of nature. So everything that's living has some amount of radiation coming from it--a very small amout. Plus there's radiation in the ground and the air. So the extremes are uranium in the soil to bananas? Yes. By the way, why do bananas have radiation? Bananas have a lot of potassium . And a small amount of potassium naturally is called potassium 40, which is radioactive What's the difference between radiation that's harmful and not harmful? Well, the term radiation can apply to a lot of different things. But the harmful radiation is ionizing radiation. It has enough energy that it can make chemical changes in material. We could get ionizing radiation from an X-ray, for example. It's the kind of radiation that causes cancer. The broader definition of radiation includes a lot of things that we call non-ionizing radiation. That includes everything like radio waves and visible light and your microwave. So what then is the largest contributor of ionizing radiation? For the natural sources of ionizing radiation, actually the biggest chunk of that tends to come from radon , which is a radioactive material that is present in the air. It can become a concern when it builds up in low-lying areas of homes like basements. Would it be fair to say that most people do not need to worry about the danger of being exposed to radiation? I would say that the everyday exposure to radioation that we meet contributes an extremely tiny risk to our life or to our health compared to all of the other risks that we meet in our day-to-day life.

mmlu_train_61553 | For poets, bird song is a beautiful expression of nature in full bloom. But for scientists, the chirps of birds are far more meaningful than just pretty sounds. Latest studies show the way that young birds learn to sing is similar to that of a human baby learning to speak. "The question we're trying to answer is how a young bird learns its song," says Professor Michale Fee of MIT. Bird's creative, trial-and-error type of learning provides an ideal model for studying similar processes in humans. An example is how a baby's babble turns into the recognizable syllables of mama and papa. Also the part of the brain that is involved in bird song is very similar to that of a human. So birds may have something to teach us about our own brains, Fee said. The study shows that young birds like to create new and imperfect songs. Gradually, the youngsters' songs become less different and more similar to the sound of their parents. Scientists disabled part of a young finch's brain and stopped the learning in midstream. The bird still sings. But never learns the right songs. Fee's team found that the part of the brain involved is called the anterior forebrain pathway. Its neurons produce random bursts that make the young bird make new sounds and compared it with that of their parents. They also find out that once a bird is old enough that part of the brain will be less active. The study does not enable us to really understand the meaning of bird language. But Fee believes it will eventually be applied to human brain diseases, such as Parkinson's disease. The subject discussed in the passage is _ . | [

mmlu_train_32621 | Earlier this year I traveled to Turkana in Kenya. I was there to take pictures of the "broken food system". As a special visitor, I was greeted with songs and dances. The locals used to sing and dance all the time but now Turkana is silent and has been for some years. No one is singing or dancing any more because they have no food, nothing to celebrate. Many of them are surviving on a little corn a day and water, which they can get just every two days. I met Tede Lokapelo, a local farmer who described the experience of a six-year drought . Tede used to have 200 goats, but now he has only seven left. He told me that this drought has taught him a hard lesson: It is too difficult to keep animals. He lives on animals. His traditional way of life has been completely destroyed now. Without the food aid they got, Tede is certain that they would starve because there are no other ways to feed themselves left. Sadly, the same can be heard in almost any developing country around the world. Almost one billion people go to bed hungry each night. The food system is broken. In Turkana, not enough rain has fallen since 2005. They measure rainfall not in days or weeks but in minutes. More and more people are being forced to rely on food aid, but people like Tede don't want food aid. They want to work and develop their country. It's our responsibility to change the situation so that they can support themselves. Drought is impossible to avoid but famine is manmade, and unless enough money is provided to develop a basic infrastructure for people in the area, thousands more lives are sure to be lost. During the drought Tede had experienced, _ of his goats were killed. | [

mmlu_train_44898 | Televisiozn ---- that most widespread and persuasive of modern technologies, marked by rapid change and growth ---- is moving into a new era, an era of extraordinary advancement and diversity, which promises to reshape our lives and our world. It is an electronic revolution, made possible by the marriage of television and computer technologies. The word 'television', coming from its Greek ( tele: distant) and Latin ( vision: sight) roots, can literally be interpreted as sight from a distance. , it works in this way: through an advanced system of electronics, television provides the capability of changing an image ( focused on a special photoconductive plate within a camera ) into electronic impulses, which can be sent through a wire or cable. These impulses, when fed into a receiver (television set), can then be electronically reorganized into that same image. Television is more than just an electronics system, however. It is a means of expression, as well as a tool for communication, and as such becomes a powerful tool for reaching other human beings. The field of television can be divided into two categories determined by its means of transmission(,). First, there is broadcast television, which reaches the masses through airwave transmission of television signals. Second, there is nonbroadcast television, which provides for the needs of individuals or specific interest groups through controlled transmission techniques. Traditionally, television has been a medium of the masses. We are most familiar with broadcast television because it has been with us for about thirty-seven years in a form similar to that exists today. During those years, it has been controlled, for the most part, by the broadcast networks, ABC, NBC, and CBS, who have been the major providers of news, information, and entertainment. These giants of broadcasting have actually shaped not only television but our understanding of it as well. We have come to look upon the picture tube as a source of entertainment, placing our role in this dynamic medium as the passive viewer.

mmlu_train_64381 | Many people would interpret "The American dream" as "living like an American"--a two-story house with a white picket fence; a family with two cars; and two children. However, the economic situation is now affecting the American way of life for 4.4 million people living in the US, according to new census data. "It's going to have a long-term impact and to say it's going to end is optimistic, " says Cheryl Russell, former editor-in- chief of American Demographics magazine. "I'm more pessimistic that this is the new normal." So what is the new normal? *Marrying later. The average age of the first marriage has increased to 28.7 for men and 26.7 for women, up from 27.5 and 25.9 respectively in 2006. At the same time, fewer people are getting married. If the marriage rate had stayed the same as in 2006, there would have been about 4 million more married people in 2010. *Fewer babies. There were 200,000 fewer births among women aged 20 to 34 in 2010 compared with two years before. This was despite the fact that the number of women of childbearing age had gone up by more than 1 million. "The recession is the likely cause ," says Kenneth Johnson, demographer at the University of New Hampshire's Carsey Institue, "Economic fertility " because women delay ...in uncertain times. *Breaking up is harder. The number of divorces has been falling for 25 years as people wait longer or choose to live together before they get married. There were about 65,000 fewer divorces in 2010 than in 2008, a 7 percent decrease. *Crowd living. Unemployment is forcing more people to live together. The number of households where people lived with "other s" climbed from 6.7 percent in 2006 to 7.2 percent in 2010. *Going public. Private school enrollment decreased from 13.6 percent in 2006 to 12.8 percent in 2010. *Fewer cars. The percentage of households without a car rose to 9.1 percent against 8.8 percent in 2006. The percent-age of households with two or more cars fell from 58 percent to 57.1 percent. *Driving solo. When people are not working, they don't carpool. The proportion of people aged 16 to 64 in employment dropped greatly in all but one of the 50 largest metropolitan areas. That has helped push the share of people driving to work alone from 76 percent in 2006 to 76.6 percent in 2010. Ride-sharing is down a full percentage point, to 9.7 percent.

mmlu_train_42410 | US military is attempting to develop a new style "insect robot" to replace the human soldier to go wherever he can't. The greatest trouble this project has fallen across is how to enable the robot to fly freely like an insect, said an official of the Pentagon . The Pentagon is seeking for the cooperation with scientists in hope of developing a new technique by which people can control the insect's flight direction and pass on the information its eyes or other organs catch through the equipment set in its body, the official said. It is thus designed that a tiny controlling chip will be equipped in an insect's body when it is in chrysalis . As the insect grows, the cut made when fixing in the chip will be recovered. The chip will exist in forever. Scientists believe this won't influence the insect, sound growth or the functions of internal organs. The _ target of the project is to set up a global system, in which the insect robots will be stationed in all parts of the world and stick to their posts till a new instruction is received. At that time the military can receive from all over the world clear image information within about 5 meters of the insects and that of a special target within 100 meters. Years ago, Defense Advanced Research Projects Agency of US DOD spent $3,000,000 carrying out a plan for training bees to detect landmines. But, no new progress has so far been made. "According to the scientists, there is still enormous difficulty in technology in turning it into reality, such as the insects reproduction , their adaptation to the surroundings and temperature and so on.

mmlu_train_58117 | Can you imagine traveling to work in a one-man submarine? Scientists believe that someday one-man submarines will be as numerous as automobiles today. One says," One day soon, men will walk on the ocean floor as they do on the street. " Perhaps during your life time, people will travel, work and live under the sea. Ships carrying oil and articles of trade will move beneath the ocean. Passenger ships will be built to travel underwater, where storms cannot delay them or make people seasick. Special underwater ships will be designed for mining, fishing, and exploring unknown areas. For military use, there may be submarines that can fly and then dive underwater to approach the battle area without being seen. First, however, the human problems associated with living in the ocean will need to be studied in detail. Many of these problems are the same as the problems of living in outer space: pressure, lack of oxygen, and weightlessness. Already scientists have begun to study these problems. In 1963 and 1964 scientists and Navy divers lived and worked underwater for several days in two projects which were called Sealab I and Sealab II. The Sealab II experiment kept the scientists and divers 215 feet below the surface for thirty days, studying marine biology, temperature, pressure, currents, and ocean bottom geology. Many puzzling questions remain unanswered, however. Man's warm blood makes it difficult for him to live long in the sea without some kind of warmth. Can our blood be changed to fit new water surroundings? What will happen to our muscles if we live in the water very long? Will they become soft away from our usual land existence? Will bones become weak and our blood pressure change? Scientists are searching for answers. By studying plants and animals deep in the ocean, scientists may find a cure for some of our most serious human diseases. We may learn to use plants to increase our world food supply. Engineers may learn to use the power of the sea by building huge walls to catch the force of the tides. In the passage, the author is talking to us about the problems of _ | [

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. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.

"So I spent time and money taking a course I had already taken before", complained Evans."The system really needs to change." Evans was part of a chorus of Ontario students on Monday cheering a new $ 73.7 million five-year plan to help students switch from college to university, and from university to college. After years' of urging from students, the Ontario government set up a new Credit Transfer Innovation loud to help students move back and forth between the more hands-on courses of community college to the often broader academic focus of a university degree." We hear horror stories about students who can't get recognition from one institution for a very similar course at another, and in one case I believe the same professor was teaching them both," noted Malloy after announcing the new fund. Individual colleges and universities have decided on nearly 500 joint deals to honor each other's credits in certain courses.Each school is required to set targets for more credit-transfer agreements, and link these increases to provincial funding. More than 4,000 college graduates transfer to university in Ontario every year twice as many as eight years ago, noted Justin Fox, president of the College Student Alliance.Yet Ontario universities and colleges have been cautious about transferring credits, in part to avoid copying each other's courses, noted Bonnie Patterson, president of the Council of Ontario Universities ,who welcomed the increased flexibility.

mmlu_train_50858 | New security camera can "see" through clothes New technology that can " see " through clothing and detect what ' s underneath can now be used to scan crowds, making it a potentially effective tool to prevent terrorist attacks in public places. The Thru Vision T5000 camera picks up Terahertz rays, or T-rays, which are naturally sent out by all objects and can pass through clothes or even walls. The camera can then detect metallic and nonmetallic objects hidden under clothing on still or moving objects without showing any body detail. While similar technology is seen at airports around the world, the T5000 is designed to be used in large, open areas. With a range of 25 meters, the T5000 can screen people in public places, thus avoiding bottle-necks at border crossing or security checkpoints. It also means people can be screened without knowing it. The technology develops from British astronomers' work in studying dying stars. Astronomers use T-ray cameras to see through dust and clouds in space. The company sees uses for its camera at other sites where political or business activities take place. For privacy concerns,Thru Vision Chief Executive Clive Beattie said the image produced by the camera did not show detailed parts of the body. " It's almost a shining light bulb ." Beattie said. "You don' t see the detail that people might be concerned about. " In London' s busy Piccadilly Circus--which is already filled with closed -circuit surveillance cameras-- reaction to the new technology was mixed.

Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase , the effect of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased. The research has caused a great deal of argument. Some think is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories."Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions,"said Roger Pitman, a professor of psychiatry at Harvard Medical School."This could relieve a lot of that suffering." But those who are against the research say that changing memories is very dangerous because memories give us our identity . They also help us all avoid the mistakes of the past. "All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we'd want to wipe those memories out," said Rebecca Dresser, a medical ethicist . Some people fear that although the drug would first be used in only very serious cases, it would become more and more common. "People always have the ability to misuse science,"said Joseph LeDoux, a New York University memory researcher. "All we want to do is help people have better control of memories." Which of the following is not the opinion of the opponents ? | [
"Our memories give us our identity.",
"The memories help humanity avoid mistakes of the past.",
"The drug should be used in only very serious cases.",
"People may not be sure whether they want to wipe the memories out."

mmlu_train_79240 | Today almost everyone knows computers and the Internet. If I ask you "What is the most important thing in your life?" may be you will say "Computers and the Internet". The first computer was made in 1946. It was very big but it worked slowly.. Today, computers are getting smaller, and smaller, but they work faster and faster. What can computers do? A writer has said, "People can't live without computers today."21cnjy.com The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, send e-mails, do some shopping, play games or make friends. 21*cnjy*com Young men, especially the middle school students like the Internet very much. They often go into the Internet bars as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don't know their names, ages and sex . They are so interested in making the "unreal friends" that they can't put their heart into study. Some of them play the games in the Internet bars all day and all night. Many of them can't catch up with others in many subjects because of that. Now the government has done many things. Some gangster Internet bars have been banned . But that's not enough. The teachers and parents are still worrying about their students and children. We can use computers and the Internet to learn more about the world. But at the same time, we should remember that computers and the Internet could not do all the things.www-2-1-cnjy-com Which is the best title of the passage? | [

mmlu_train_78881 | The first robot was invented in the 1920s. Robots have appeared in many American films. In some films, they are stronger, faster and cleverer than people. In real life, robots are mainly used in factories. They do some dangerous and difficult jobs for humans. Robots also help disabled people, for example, blind people. Today many blind people have a guide dog to help them. In the future, guide dogs might be robot dogs. One kind of robot guide dog has wheels. It moves in front of the owner. It is very clever. It knows the speed of its owner's walk. The owner wears a special belt. The belt sends instructions to the owner from the dog, such as "Stop here" "Turn left" or "Turn right". In the United States, another kind of robot helps disabled people to take care of themselves in their daily life. The robot hears the sound of its owner's voice. It follows instructions such as. "Turn the page" or "Make a cup of coffee". Robots are also used in American hospitals. They can do simple jobs. At one hospital, for example, a robot takes meals from the kitchen to patients' rooms. It never gets lost because this robot has a map of the hospital in its computer memory. Though robots can help people in many different ways, they will never take the place of humans. ,.

mmlu_train_62690 | Scientists have claimed a milestone in the drive for new energy--development of the first practical artificial leaf, an advanced solar cell that imitates the process,called photosynthesis ,that green plants use to make sunlight and water into energy. "A practical artificial leaf has been a dream of scientists for decades,"said Daniel Nocera,who led the research team."We believe we have made it.The artificial leaf shows particular promise as an inexpensive source of electricity for homes of the poor in developing countries. One can imagine villages in India and Africa soon purchasing an affordable basic power system based on this technology." The leaf is like the shape of a poker card but thinner.Placed in water in a bright sunlight,it could produce enough electricity to supply a house in a developing country with electricity for a day by splitting water into hydrogen and oxygen, which are stored in a fuel cell to produce electricity. The"artificial leaf"is not a new concept.The first artificial leaf was developed more than a decade ago by John Ttlrner.However, it was impractical for wider use,as it was composed of rare,expensive metals and was highly unstable with a lifespan of barely one day. Nocera's new leaf overcomes these problems.It is made of inexpensive materials that are widely available,works under simple conditions and is highly stable.Laboratory studies showed that it could operate continuously for at least 45 hours without a drop in activity. The key to this breakthrough is Nocera's recent discovery of several new powerful, inexpensive catalysts,which are able to accelerate the chemical reaction under simple conditions.Right now, Nocera's leaf is about 10 times more efficient at carrying out photosynthesis than a natural leaf.Yet he is optimistic that he can boost the efficiency of the device much higher in the future. According to the passage, catalysts in the artificial leaf _ . | [
