mmlu_train_29298 | What is the difference between a college and a university? This is a good question for students who want to attend a college or a university in the United States. Colleges and universities have many things in common. Both provide a greater understanding of the world and its past. Both provide education in the arts and sciences. And both can help prepare young people to earn a living. Students who complete their undergraduate studies either at a four-year college or a university receive a bachelor's degree. One difference is that many colleges do not offer graduate studies. Universities are generally bigger, offer more programs and do more research. Modern universities developed from those of the Middle Ages in Europe. The word "university" comes from the Latin "universitas". This described a group of people organized for a common purpose. The word "college" comes from a Latin word with a similar meaning, "collegium". In England, colleges were formed to provide students with places to live in. Usually each group of students was studying the same thing. So college came to mean an area of study. But a college can also be a part of a university. The first American universities divided their studies into a number of areas and called each one a college. This is still true. Programs in higher learning may also be called schools. The University of Arizona in Tucson, for example, has 18 colleges and 10 schools. They include the colleges of pharmacy , education, engineering and law. They also include the schools of architecture, dance and public administration. College is also used as a general term for higher education. A news report might talk about "college students" even if they include students at universities. Or someone might ask, "Where do you go to college?" Today, most American colleges offer an area of study called liberal arts. These are subjects first developed and taught in ancient Greece. They include language, philosophy and mathematics. The purpose is to train a person's mind instead of teaching job skills. When the term "college students" appears in a newspaper, it may refer to _ . | [

mmlu_train_67721 | Teens are gaining weight. Today most teenagers are at least one size larger than teens were 20 years ago. Even clothing sizes have changed. Did you know that a small today used to be a medium, 20 years ago? A recent research shows 97%of teens need more exercise. It's bad news because too little exercise means you are missing a lot of good things in life. Exercise helps in two ways. First,exercise helps your body. Physical activity can make your body strong. It can also keep you at a healthy weight. Doctors say that people who stay at a healthy weight have fewer health problems. Second,exercise can help your mind. People who get plenty of physical activity might worry less and sleep better at night. You may even learn better in school. Students who are healthy can listen and understand better in class. So you can change your life and be more active at any point. It's never too late. An article called "How to Limit Screen Time and Get Moving"gives these ideas: Step away from the screen. Doctors call watching TV or playing video games screen time. You should have no more than two hours of screen time a day. You will enjoy life more if you live it instead of watching it! Start slowly. An hour a day can seem like a long time. Start with 10 minutes of new activities every day. Add more as you get stronger. Think about walking. Take the stairs instead of the lift. You will feel healthier. Make fitness fun. Find a sport you like. It doesn't need to be the traditional sports of basketball, soccer,or baseball. Those are all great sports and if you like them, play them. However,you can also try hiking,skateboarding,or even rope jumping. If you enjoy the sport,you will do it. Choose food carefully. Help your family shop for healthy food. Read the labels .Look for healthy foods. Eat lots of fiuits and vegetables. Stop buying soft drinks and junk foods. You will feel better if you eat right. Exercise with others. Find a friend or family member to exercise or play with you. You will have more fun and it helps keep you responsible for going.

mmlu_train_5687 | One advantage of the Internet is shopping conveniently online for clothes; one disadvantage of the Internet is also shopping conveniently online for clothes. "Nothing fits," said Lam Yuk Wong, a senior in electrical and computer engineering at Rice University. "Everyone says this. They order clothes and they don't fit. People get very unhappy." Wong and her design partner, Xuaner "Cecilia" Zhang, are Team White Mirror, creators of what they call a "virtual fitting room". Their goal is simple and consumer-friendly: to let online clothing shoppers have a perfect fit and a perfect look when shopping every time. Both women are from China, Wong from Hong Kong and Zhang from Beijing. They both order most of their clothing online. They got the idea from their own experience as consumers and from listening to the complaints of friends and relatives. "They say, 'The color is wrong' or 'I got the right size but it still does not fit.' We want to make it like you're in the store trying on the clothes," Zhang said. Using a Kinect developed by Microsoft for use with its Xbox 360 video game player, Zhang scans Wong and turns her image into, in effect, a virtual model, keeping Wong's dimensions , and even her skin and hair color. "We put the clothes on the shopper's 3-D body models and show how they look when they are dressed," Wong said. So far, Wong and Zhang have adapted the software to show dresses and shirts, and they are now working on shorts. Asked if she thought men as well as women might be interested in using their virtual fitting room, Wong said, "I think their wives will care about this, so it will also be important to men."

mmlu_train_35738 | Counterfeit medicines are a widespread problem in developing countries. Like other _ , they look like real products. But counterfeit drugs may contain too much, too little or none of the active ingredients of the real thing. People do not get the medicine they need. And in some cases the counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen . The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money. The problem of counterfeit medicines is especially serious in Africa, Asia and Latin America. The WHO estimates that up to thirty percent of medicines on sale in many of those countries are counterfeits. The problem is less widespread among industrialized countries. The WHO says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan, and New Zealand. But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit. Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify . And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking codes for drug packages. People could send a text message with the code and get a message back, which proves that what they bought is listed in a database.

mmlu_train_86215 | Sing the Language You're Learning How can you remember a song from your childhood to this day? Why do your teachers use songs to teach you English? It seems there is a scientific reason for this. Researchers are now studying the relationship between music and remembering a foreign language. They find that remembering words in a song is the best way to remember even the most difficult language. "Singing could be a new way of learning a foreign language. The brain likes to remember things when they are used in a _ and meaningful way", said Dr, Karen Ludke. The findings may help those who have difficulties learning foreign languages. On his blog, Dr. Ludke writes, "A listen-and-repeat singing method can support foreign language learning, and opens the door for future research in this area." Many language teachers know the value of using music and singing. Hua Zhuying, a teacher at a Chinese language school in Washington, D.C. depends heavily on songs in teaching Chinese. She says, "I use music all the time to teach children Chinese. For little kids usually we use the music. Not only does it work, but it is fun for kids." "Sometimes, I think if I were taught English that way, maybe I could speak much better English than now," Hua Zhuying adds. Our brain likes music, especially for remembering. So, if you're still struggling in learning a language, why not try singing it out ? From the passage, we know that Hua Zhuying _ . | [

mmlu_train_44111 | You could have poor eyesight because you didn't spend enough time outdoors as a child, according to the conclusion of some studies on short-sightedness published in the Optometry and Vision Science. Although short-sightedness can easily be corrected with glasses or contact lenses , it's much better to prevent it altogether. This means we should allow the eyes to develop the way they should in childhood. Children need to spend more time outdoors, focusing on distant objects, say the Australian researchers. This gives the eyeballs a chance to develop as they should. According to one study on short-sightedness, the risk of developing short-sightedness is great -- about 60 percent -- in children who get five hours or less per week of outdoor activities. But if they do outdoor activities for 14 hours or more a week, the risk drops to 20 percent. Spending time outdoors can even help people overcome a genetic predisposition to short-sightedness. Children with parents who are short-sighted can bring down their risk by spending a few hours a day outdoors, suggest the findings from another of the studies presented at the conference. It's being in an outdoor environment that seems to be important, not the type of activity. Studies show that both active and passive outdoor activities have the same protective effect. So encourage children to balance the time they spend reading and studying with time outside. Two to three hours a day outside of school hours is the suggested amount by scientists. If it's hard to find that time, then cut the amount of television and reduce the time they spend on computer games and get kids to take frequent breaks outdoors when reading and studying. To protect their eyesight, what are children mainly advised to do? | [

mmlu_train_18243 | TOKYO -- The number of domestic infections cases of influenza A/H1N1 in Japan hits 42 on Sunday after a total of 34 people in Osaka and Hyogo counties were confirmed to have been infected, local media reported. The total number of the infection in the country now stands at 46, including the first four cases contracted abroad. The country is now facing the risk of grass-root outbreak which could lead the WHO to raise its new flu pandemic alert to the highest level of 6 from the current 5, experts has warned. The 34 newly confirmed domestic cases, 11 in Osaka and 23 in Hyogo, included high school students, college students and teachers, the health ministry and local governments said Sunday. Japan on Saturday confirmed the first eight cases of domestic infection on students of a Kobe high school. The later confirmed cases in Osaka are said to have contacted the Kobe students in a volleyball match. Osaka and Hyogo are neighboring in the Kansai region. All of the 42 people had no record of overseas travel. Meanwhile, a total of 143 students at the Kansai Okura Senior High School where many infections in Osaka were found, have shown symptoms of influenza since around Monday, according to local media reports. The privately run school said it will be closed from Monday through Saturday. More than 1,000 educational facilities -- kindergartens, and elementary, junior and senior high schools -- in Osaka and Hyogo counties have decided to suspend classes for certain periods following the confirmation of new flu infections in the counties, Kyodo News reported. The two counties have requested private schools to follow suit. Osaka Governor Toru Hashimoto held a meeting of a new flu task force on Sunday and decided to ask facilities such as movie theaters to suspend operations to prevent the spread of the flu. TV clips showed people in Kansai region started to wear masks in public spaces and rushed to drug stores for buying medicines. The Japanese government on Saturday shifted the stage of its new-flu action program from "a period of overseas outbreak" to "a period of domestic outbreak" and called for companies and schools in the areas concerned to allow individuals to avoid commuting during rush hours. The Kyodo News quoted Masato Tashiro, a member of the World Health Organization's emergency committee, as saying that several hundred people in Japan already may have been infected with the new flu.

mmlu_train_41469 | In recent years, temperatures in the polar areas are rising faster than anywhere else on Earth. As a result, the ice and the snow are melting at record-setting rates. One result is that sea levels are rising around the world, putting animals and people at risk. A sheet of ice acts like a huge mirror, reflecting the sun's energy. But ocean water, which is darker than ice, absorbs a lot of it. This causes the ocean to warm, which in turn speeds up ice melting and which leads to even more open waters. The cycle continues until all the ice is gone. "As the ice melts, water flows into the oceans, making them less salty. That, along with warmer water temperatures, can harm the creatures that live in, under, and near the ice," says zoologist Michael Stoddard. "Cold-adapted animals -- including polar bears, foxes, hares, and seals -- also need ice for travel and survival." "Most species of fish, sea spiders, and many other animals and plants that live in the waters of Antarctica don't live anywhere else," Stoddard says. "Many of them have special proteins in their bodies keeping them from freezing to death and have other adaptation to the cold that has yet to be explored." Therefore, experts are urging us to reconsider the way we live. The fuels that we burn in cars, power stations, and factories are largely to blame for the carbon dioxide and other greenhouse gases that are trapping overmuch heat in our atmosphere. If we can produce fewer of these gases, we can help save the polar ice. "Even small things would make a difference, if everyone did them." Michael Stoddard says, "That's what we have to figure out in the near future to help save the polar ice and thus protect the oceans and us." Which of the following statements is TRUE? | [

mmlu_train_26045 | Should every teenager be given a vaccine against the effects of nicotine, and so prevent them becoming addicted to cigarettes? This controversial possibility seems likely to happen in the future, thanks to the development of a new vaccine for nicotine addiction. The vaccine was designed for people who want to quit smoking but who repeatedly relapse .But since most countries are failing to cut the number of children taking up smoking, many people will want to know whether the vaccine should be used far more widely if it proves to be effective. "The vaccine will be tested first on relapsing smokers, then on those who plan to quit, then on those who are not yet completely addicted," says Frank Vocci of the National Institute of Drug Abuse. "The final step would be vaccinating young people before they even try smoking, but that's a long way down the road." John Roberts, medical director of British drug company Xenova, is very enthusiastic. "I think prevention is a huge opportunity," he says. "If you can take away the pleasure nicotine gives, then teenagers who start smoking are more likely to stop before it becomes a habit." 80% of smokers start in their teens, with 360,000 teenagers and children in the US taking up the habit per year. But would the vaccine be given to all teenagers or only a selected few? "It's hard to decide which children are most at risk of becoming smokers," says Amanda Sandford of Action on Smoking and Health. Instead she favors education as a way of discouraging children from smoking. Nabi Biopharmaceuticals is also cautious, "It is very difficult to know what is the right age to give the vaccine to children." There are also worries about giving the vaccine to long-term adult smokers. Will addicted smokers simply try to beat the vaccine's antibodies by smoking more? Gary Norwith, Nabi's clinical director, says this would be almost impossible. "You'd have to stick an entire pack of cigarettes in your mouth and smoke for hours to beat the antibodies," he says. What may Sanford agree with? | [

mmlu_train_5210 | "Particulate Matter 2.5(PM2.5 for short)"is now ,it seems, officially an enemy of the people.The harmful,tiny pieces of matter,up to 2.5 microns in diameter, are too small to be seen by the naked eye.So they can be easily breathed into the lungs of people and do harm to people's health.With the issue of pollution so heatedly discussed,some people are wondering what possible solutions might be on the way. _ might very well be a renewed effort to kick-start the electric car industry.Some reports suggest that the use of bakery cars should be expanded from the present five cities to 20 more. But so far no country in the world has succeeded in making the dream of emission.free driving a reality.Despite the lofty ideal,the electric car has so far been a disappointment, accounting for only a fraction of l%of global car sales.And the same is true in China.There is an existing target to put five million on the road by 2020 but the Chinese consumer is so far very much unconvinced. BYD Auto Company in the southern city of Shenzhen is just one electric vehicle maker hoping that the time is now ripe for the government to step up its efforts.BYD is making electric cars but as yet not selling in great numbers.Electric cars are not cheap.It would still leave more than$40,000 to be paid before you could drive away in a BYD e6.And buyers have worries other than price. "I think that when you talk to a regular Joe about electric vehicles he is excited, but when you ask Mr. Joe to buy one,he's nervous,"said Isbrand Ho from BYD's Auto Export Trade Division."We call that 'range anxiety'.How far will my vehicle go?" The answer for an e6 is well in excess of 300 kms(190 miles)on one charge.That is the sort of number that might just start looking attractive to less price-sensitive customers but China still doesn't have anything like enough charging stations to make the car a practical choice. Last year, BYD sold only l,700 electric cars in China.Isbrand Ho tells me that at that volume the car is naturally expensive,due to the economy of scale.What they need, he says, is for production to get above a certain threshold(,),and then costs will come down. According to Isbrand Ho, will bring down the price of the electric cars. | [

mmlu_train_51529 | Flight Distance Any observant people have noticed that a wild animal will allow a man or other potential enemy to approach only up to a given distance before it escapes. "Flight distance" is the terms used for this interspecies spacing. As a general rule, there is a positive relationship between the size of an animal and its flight distance --- the larger the animal, the greater the distance it must keep between itself and the enemy. An antelope will escape when the enemy is as much as five hundred yards away. The wall lizard's flight distance, on the other hand, is about six feet. Flight is the basic means of survival for mobile creatures. Critical Distance Critical distance apparently is present wherever and whenever there is a flight reaction. "Critical distance" includes the narrow zone separating flight distance from attack distance. A lion in a zoo will flee from an approaching man until it meets a barrier that it cannot overcome. If the man continues the approach, he soon penetrates(,)the lion's critical distance, at which point the cornered lion turns back and begins slowly stalk the man. Social Distance Social animals need to stay in touch with each other. Loss of contact with the group can be fatal for a variety of reasons including exposure to enemies. Social distance is not simply the distance at which an animal will lose contact with his group --- that is, the distance at which it can no longer see, hear, or smell the group --- it is rather a psychological distance, one at which the animal apparently begins to feel anxious when it goes beyond its limits. We can think of it as a hidden band that contains the group. Social distance varies from species to species. It is quite short --- apparently only a few yards --- among some animals, and quite long among others. Social distance is not always rigidly fixed but is determined in part by the situation. When the young of apes and humans are mobile but not yet under control of the mother's voice, social distance may be the length of her reach. This is readily observed among baboons in a zoo. When the baby approaches a certain point, the mother reaches out to seize the end of its tail and pull it back to her. When added control is needed because of danger, social distance shortens. To show this in man, one has only to watch a family with a number of small children holding hands as they cross a busy street. If a lion's critical distance is penetrated, it will _ | [

mmlu_train_33377 | People should listen to music for no more than one hour a day to protect their hearing, the World Health Organization (WHO) suggests. It says 1.1 billion teenagers and young adults are at risk of permanently damaging their hearing by listening to "too much, too loudly". It said audio devices , concerts and bars were causing a "serious threat". WHO figures show 43 million people aged 12-35 have hearing loss and the number is increasing. In that age group, the WHO said, half of the people in rich and middle-income countries were exposed to unsafe sound levels from personal audio devices. Meanwhile 40% were exposed to damaging levels of sound from clubs and bars. The proportion of US teenagers with hearing loss went from 3.5% in 1994 to 5.3% in 2006. "What we're trying to do is raise awareness of the problem that is not talked about enough, but has the potential to do a lot of damage that can be easily prevented," said Dr Etienne Krug, the WHO's director for injury prevention. The full report argued: "While it is important to keep the volume down, limiting the use of personal audio devices to less than one hour a day would do much to reduce noise exposure." Dr Krug said: "That's a rough recommendation, it is not by the minute, to give an idea to those spending 10 hours a day listening to an mp3-player. But even an hour can be too much if the volume is too loud." Which of the following ideas would Dr Etienne Krug agree with? | [

mmlu_train_58597 | The card using a built-in voice-recognition chip requires users to give a spoken password that it recognizes. The idea is to prevent thieves from using a stolen card to buy goods online. A model built by engineers in California packs a microphone, a loudspeaker, a battery and a voice-recognition chip into a standard-sized credit card. The card is the length and width of an ordinary credit card but about three times as thick. The company now plans to make it thinner. The voice card is based on an earlier Beep card technology designed to prevent fraud in online deals. The Beep card has no microphone, but has a built-in loudspeaker to utter an audible ID signal by a computer's microphone to an online server . By confirming that signal matches the information in the card, the server can make sure that the user is not simply keying in a credit card number but actually has the card in his hand. The ID code, which only the server knows, changes each time the card is used. This prevents fraudsters recording the beeps, noting the card details and then playing back the audible ID when they key in the details later. But this earlier Beep card technology cannot prevent illegal use of stolen cards. The new voice card can. The new voice card doesn't identify itself by its ID until it has confirmed the real user's spoken password. Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner's voice with a high degree of accuracy. The challenge for Beep card has been to develop voice-recognition and audio circuitry . The voice-recognition credit is powered by a mini battery. To extend batter life, the electronics have only to be switched on when the card is being used. Pressing a button on the card's surface allows one to hear a female voice saying, "Say your password." If the voice-recognition software proves that the password is real, it sends its ID, which the server then identifies, allowing the deal to continue. What is the problem with the model card? | [

mmlu_train_7073 | Generations of Americans have been brought up to believe that a good breakfast is essential to one's life. Eating breakfast at the start of the day, we have been told, and told again, is as necessary as putting gasoline in the family car before starting a trip. But for many people, the thought of food as the first thing in the morning is never a pleasure. So in spite of all the efforts, they still take no breakfast. Between 1977 and 1983, the latest year for which figures could be obtained, the number of people who didn't have breakfast increased by 33%--from 8.8 million to 11.7 million--according to the Chicago-based Market Research Corporation of America. For those who dislike eating breakfast, however, there is some good news. Several studies in the last few years have shown that, for grown-ups especially, there may be nothing wrong with omitting breakfast. "Going without breakfast does not affect work," said Arnold E. Bender, former professor of nutrition at Queen Elizabeth College in London, "nor does giving people breakfast improve work." Scientific evidence linking breakfast to better health or better work is surprisingly inadequate, and most of the recent work involves children, not grown-ups.

"We are excited by the findings because we saw such a meaningful improvement in both clinically depressed and non--depressed students,"said lead author Dr.Brandon Alderman."It is the first time that both of these two behavioral ways have been looked at together for dealing with depression." Researchers believe the two activities have an interactive effect in _ depression.Alderman and Dr.Tracey Shors discovered that a combination of mental and physical training (MAP)enabled students with major depressive disorder not to let problems or negative thoughts defeat them. Rutgers researchers say those who participated in the study began with 30 minutes of focused attention meditation followed by 30 minutes of oxygen sport.They were told that if their thoughts drifted to the past or the future they should refocus on their breathing,enabling those with depression to accept moment-to-moment changes in attention. Shors,who studies the production of new brain cells in the hippocampus--part of the brain involved in memory and learning--says scientists have shown in animal models that oxygen sport exercise keeps a large number of certain cells alive. The idea for the human intervention came from her laboratory studies,she says,with the main goal of helping individuals acquire new skills so that they can learn to recover from stressful life events. By learning to focus their attention and exercise,people who are fighting depression can acquire new learning skills that can help them process information and reduce the overwhelming recollection of memories from the past,Shors says.

The polluted land,which is mostly in economically developed areas,accounts for one-tenth of the country's total arable land,according to an incomplete survey by the State Environmental Protection Administration,China's top environment watchdog. Pollution on cultivated land threatens the environment,food safety and the sustainable development of agriculture,the administration said. Because of continual,too much use of chemical fertilizer, pesticide and agricultural plastic sheeting, as well as irrigation using polluted water, a large amount of contaminants remain in the cultivated land. The contaminants affect the soil's ecological structure and function,leading to decreased soil productivity, lower crop yield ,and lower quality of agricultural products- It also leads to worse water quality in rural areas. Less than 9 per cent of drinkable water passed checks for bacteria in243 rural water supply stations across the county. Another survey, which took samples of drinking water and groundwater an 69 small towns. in Beijing, Tianjin and Hebei Province of North,China, showed that more than half of the water contains too much nitrate ,which may cause diabetes and damage the kidney.

mmlu_train_77896 | Do you know why different animals or pests have their special colors? Colors in them seem to be mainly used to protect themselves. Some birds like eating locusts , but birds cannot easily catch them. Why? It is because locusts change their colors with the change of the colors of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change into the same brown color as crops have. Some other pests whose colors are different form plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night. If you study the animals' life, you'll find the main use of colors is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters because their colors are much like the trees. Colors are useful not only on the land, but also in the sea. A kind of fish in the sea can give out a kind of black liquid when the fish face danger. The liquid spreads over quickly, so they cannot be found by their enemies and can quickly swim away. That is why they live safely though they are not strong at all.

mmlu_train_18353 | People have always wanted to speak with animals. There are many books about this, especially children books. Now there are also movies, such as Dr. Doolittle. When you watch animals, it seems clear that they can communicate with each other. Many people wonder why people can't also communicate with them. Scientists know how some animals communicate. Bees, for example, use their bodies. They do a kind of dance to give information about food. Birds, on the other hand, share information with sounds. They use certain sounds to protect their homes and to stay together when they fly. Some male birds use lovely songs to attract a female . Other animals communicate with both body movements and sounds. For example, dogs wag their tails when they are happy, and they bark when they are excited. People used to think it was possible to teach human language to animals. Parrots and other birds, for example, can learn to say words. But the birds just repeat the words. They don't understand them. Some American scientists tried to teach English to chimpanzees , close s of human beings. However, this was impossible. Chimpanzees can't move their mouths the right way. They could never learn to speak like people. Then scientists tried to teach human language to chimpanzees in other ways. Some tried with American Sign Language (ASL). Others tried with a simple computer. But chimpanzees could only learn to use a few words. They could never learn to use grammar. Their brains are very different from the brains of human beings. Now some scientists are studying the same points between human and animal language. In fact, some animals use sounds like people do. Dogs, for example, use an unpleasant, low sound to tell other dogs to stay away. People, too, use that kind of voice to say the same things. A dog's noisy bark communicate that something is happening. People use the same high tone when they shout, "Watch out!" Scientists want to understand the language of other animals, such as whales and bears. To do this, they go out to the animals' natural homes. They watch the animals for days or even years. They take pictures and make tape recordings and share the information with other scientists. In this way, they hope to learn more about the way animals communicate, and maybe someday we'll be able to communicate better with them. Bees do a kind of dance to _ . | [

mmlu_train_22829 | Look closely at ,your hands-are they clean? It doesn't matter how many times you was your hands. They're still crowded with microbes, which are also called "germs" or "bacteria". Microbes are everywhere. But don't worry-most microbes don't harm you. and many actually help you stay alive. Now, scientists say the microbes that live on our hands could be used in a surprising way: fighting crime. When police visit the scene of a crime, they often look for fingerprints to try to identifythe criminal. But according to a recent study, investigators could even use microbes to help break a criminal case. Every person has his or her own set of microbes that live on their hands, according to scientists at,the University of:Colorado. That means the mix of different kinds of microbes on everybody's hand is unique-much like one's fingerprint. The scientists wanted to know whether this microbe mix could be used as a new kind of fingerprint-especially in a crime scene where fingerprints might be hard to find. And policemen use forensics such as studying fingerprints to identify the criminal. "Microbe fingerprints are harder to hide," said Noah Fierer, one of the scientists. "You can't sterilize(......) a surface just by wiping it off. " His team compared the bacteria on the hands of 273 people with the bacteria found on each person's computer keyboard. For the study, the keyboards had been used only by the people who were being tested. The study showed that the mix of microbes from each per- son's hands matched the mix of microbes on that person's keyboard. The scientists were easily able to tell the 273 people apart-just by looking at their keyboards. But there are a lot more than 273 criminals. Other scientists wonder whetherthe microbe fingerprint can really be that useful. Fierer agrees that scientists have a lot more work to do before the microbe fingerprint will be a useful tool. What did Fierer's team find through the study? | [

mmlu_train_86295 | Do you know how to be a healthy kid? Here are some rules you should follow. First, eat different food, especially fruits and vegetables. You may have a favorite food, but you'd better eat something different. If you eat diff You can't watch TV for more than two hours a day errant food, you will probably get more nutrients your body needs. Second, drink water and milk as often as possible. When you are really thirsty, cold water is the No. 1 choice. Milk is a great drink that can give you more calcium your body needs to grow strong bones. Third, listen to your body. How do you feel when you are ill? When you're eating, notice how your body feels and when your stomach feels comfortably full. Eating too much will not make you feel comfortable and make you feel fat. Fourth, limit screen time. Screen time is the time you watch TV, DVDs and videos, or using computers. It is good to take more exercise such as basketball, bike riding and swimming. You can't watch TV for more than two hours a day. Fifth, be active. One thing you'd like to do, as a kid, is to find out which activity you like best. Find ways to be active every day. You shouldn't watch TV for _ a day. | [

mmlu_train_25734 | The making of glass is a very old industry---at least 4,500 years old. Glass has many extraordinary qualities and it is often being used in new ways. One of the most interesting new uses for glass is in telephone communication. Scientists have developed glass fibers as thin as human hair which are designed to carry light signal. When the light reaches the other end,it is first changed into electrical signals , which are in turn changed into sound messages. Called lightwave communication, the new system was used successfully in an experiment in Chicago in 1977. During the experiment, two glass fibers were able to carry 672 conversations at the same time. The lightwave cable , containing 144 glass fibers, is able to carry 50,000 conversations at the same time. The lightwave communication system has two important advantages. First, the glass fiber cables are smaller and weigh less than copper cables. Second, they cost less. Perhaps it can be said that telephone communication has entered the age of light. One of the extraordinary qualities of glass is that it can carry _ . | [

mmlu_train_62347 | Computer people talk a lot about the need for other people to become "computer-literate." But not all experts agree that this is a good idea. One pioneer, in particular, who disagrees is David Tebbutt, the founder of Computertown UK. Although many people see this as a successful attempt to bring people closer to the computer. David does not see _ that way. He says that Computertown UK was formed for just the opposite reason, to bring computers to people and make them "people-literate." David Tebbutt thinks Computertowns are most successful when tied to a computer club but he insists there is an important difference between the two. The clubs are for people who have some computer knowledge already. This frightens away non-experts, who are happier going to Computertowns where there are computers for them to experiment on, with experts to encourage them and answer any questions they have. They are not told what to do, they find out.The computer experts have to learn not to tell people about computers, but have to be able to answer all questions people ask. People don't have to learn computer terms , but the experts have to explain in plain language. The computers are becoming "people-literate." We can infer from the text that "computer-lilerate" means _ . | [
