mmlu_train_16973 | New findings suggest that brainy card games such as contract bridge may temporarily raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased levels of immune cells, according to the research reported last week. A researcher, Diamond, studied bridge players from a women's bridge club. She chose bridge players because the game includes skills stimulating a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system. The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland and used by the immune system against diseases. The T cell count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology , whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated systems. What isn't clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It is also not clear whether the increase in T cells could finally be targeted against special illnesses. Which of the following is true according to this article? | [

mmlu_train_52857 | In 1975, George Carlin appeared on a popular TV show, Saturday Night Live, with his famous words about blue food. "Why is there no blue food? I can't find blue food--I can't find the flavor of blue! I mean yellow is lemon; orange is orange and red is cherry. Where is the blue food? " Well, Carlin pretty much has it right--there's not no blue food, but there's certainly not a lot of it. Fresh-picked blueberries are blue, though they become purple when they are turned into jam. The blue in blueberries--like the purple in grapes and the red in tomatoes--is found in nature. But it isn't a hot color for food. People don't seem to prefer blue food. Some diet programs even suggest that those determined to lose weight should make their food blue. Eating, in part, begins with our eyes. Charles Spence--an experimental psychologist from Oxford University--points out that color can change our taste experience. Commonly, we consider red-colored foods up to 20% sweeter than they actually are; and green foods as being more sour. Spence suggests: human expectations may be influenced by our long history of watching - green fruits can become sweet as they grow up and turn red. But what about blue? Except blueberries, much of the blue food we see these days _ blue artificially. Food producers argue that artificial color doesn't do much harm to health. A lot of research shows that some physical problems of kids are related to food dyes--while other studies show no effects at all. Blue birthday cake or even blue-dyed chicken can be served on the dinner table. So what? George Carlin's words are placed at the beginning of the passage to _ . | [

mmlu_train_83205 | Did you sleep the day away on March 21? Well, you should have done that because it was World Sleeping Day. This is the one day of the year when people around the world care about their sleep and ask themselves a lot of questions about sleep. Why do we need sleep? Nobody as yet can give a correct answer to this question. However, tests have shown that lack of sleep over about four weeks leads to a strong drop in body temperature, great weight loss and finally sickness. Different people need different amounts of sleep. Eight hours a night is considered the average amount of sleep. For teenagers the least number of sleeping hours advised by doctors are ten hours for primary school students, nine for junior highs and eight for senior highs. Some people seem to get along just fine with very little sleep at night. Leading American scientist Thomas Edison said that sleep was a waste of time. He did, however, take naps during the day. On the other hand, Albert Einstein, another great scientist, said he needed at least ten hours' sleep a night. Here are some of the most useful suggestions, for a good night's sleep. Go to bed regularly. Use your bed only to sleep. Don't exercise in the evening. Keep the bedroom dark and quiet. Drink a glass of milk before sleep. Which is the best title of this passage? | [

mmlu_train_48158 | It takes two to duet , and one question for scientists is how these coordinated performances arise -- in birds. Are they the result of cooperation, a way in which one pair signals to others that they've got it together? Or are they the result of conflict, evolving to avoid one partner's song interfering with the other's? A study of duetting in Peruvian warbling antbirds suggests that it might be a little of both, and that context is everything. Joseph A. Tobias and Nathalie Seddon of the University of Oxford show in Current Biology that sexual conflict can cause the female of a pair that normally cooperates to "jam" the male's song by singing over it. The researchers exposed antbird pairs to recorded songs of other antbirds and monitored the songs the pairs produced. In one experiment, they played the songs of an intruding pair. In this case, the resident pair "both are likely to lose their territory, so both should cooperate," Dr. Tobias said. And they do. They produce a coordinated duet that in effect tells the intruders to keep away. But when the researchers played the song of a single female, the pair behaved differently. "You'd expect the resident female to be highly motivated to defend her position in the partnership," Dr. Tobias said. And that's what occurs. The male sings its heart out, flirting with the single female, and the female of the pair does its best to interfere with the song by singing over it, apparently to make her mate less attractive to the other female. "It's clear that the male doesn't like what she's doing," Dr. Tobias said. The behavior "breaks up what is otherwise a very cooperative situation into a more complicated signal," he added. It's the first evidence of this kind of signal jamming among pairs, Dr. Tobias said. And in that it leads the male to alter its song to avoid the female's interfering notes, it shows that this kind of conflict could, over a long period, drive the evolution of coordinated song. How did the researchers conduct the experiment? | [

mmlu_train_9953 | Being physically active three times a week reduces the odds of being depressed by about 16%, according to new UCL research carried out as part of the Public Health Research Center. The study, published in JAMA Psychiatry, found a two-way relationship between depression and physical activity. People who increased their weekly activity reported fewer depressive symptoms but those with more depressive symptoms were less active, particularly at younger ages. Researchers followed 11,135 people born in 1958 up until the age of 50, recording depressive symptoms and levels of physical activity at regular intervals in adulthood. They found that each additional activity period per week reduced odds of depression by 6%. In England 19% of men and 26% of women are currently classed as "inactive", and this study suggests that activity could significantly improve their mental as well as physical health. "Assuming the association is causal, physical activity has a protective effect against depression. If an adult between their twenties and forties who isn't physically active became active 3 times per week, they would reduce their risks of depression by about 16%." says Dr Snehal of the UCL Institute of Child Health, lead author of the study. Professor Mark, Director of the Public Health Research Center, said, "Many people are already aware of the benefits of physical activity on their general health, but now we are seeing more evidence that suggest it also has a positive effect on a person's mental well-being. The latest research highlights just how important it is to ensure that people are working and living in environments that allow them to be both physically active and mentally healthy." Which of the following statements is TRUE according to the passage? | [

mmlu_train_44363 | Let's face it -- you're going to get a lot of well-intentioned advice from friends, parents and grandparents about your sleep. Some of this advice is going to be just wrong. Myth 1: Sleeping late on the weekends will make up for lost sleep during the week. Fact: Getting less than the amount of sleep that you need night after night accumulates over time and starts to create a "sleep debt". And like all debts, eventually you need to pay the price. The problem with waiting until the weekend to meet sleep needs is that in the meantime, you are paying the price of being less alert, feeling more moody, thinking slower and having less stimulation. Myth 2: A boring teacher (or warm room, full stomach, etc.) can put teens to sleep. Fact: If you are getting enough sleep on a regular basis, there is no teacher, math book or reading assignment in the world boring enough to make you fall asleep in class. There are basically two things that make people sleepy -- not getting enough sleep and not getting good quality sleep. The environment kids are in, including the room temperature, light level and entertainment value, may unmask underlying sleepiness, but the environment does not cause it! So if you are dozing off in class, don't blame it on bad teaching. Myth 3: Teenagers can pull an all-nighter to study and still be ready for the big test in the morning. Fact: Teenagers are much better off studying less and getting a good night's sleep. Research clearly shows that the ability to concentrate and learn new information, as well as to work efficiently, declines sharply after being awake for 15-16 hours, and continues to bottom out the longer you stay up. Plus, if the big test is at 8:00 am, the problem gets even worse. That's because morning time typically represents a low energy point in the body's normal 24-hour circadian rhythm, especially in teenagers.

But to those who are new to it all, sometimes it can be confusing. October is usually the busiest month in the college calendar. Universities have something called Freshers' Week for their newcomers. It's a great opportunity to make new friends, join lots of clubs and settle into university life. However, having just left the comfort of home and all your friends behind, the prospect of meeting lots of strangers in big halls can be nervewracking . Where do you start? Who should you make friends with? Which clubs should you join? Luckily, there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly.

Scientists are finding evidence that gum chewing may be good for your health.It may even help boost your test scores. This exciting research is just beginning.And in the meantime,companies are also experimenting with adding vitamins,minerals,medicines,and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath. People have been chewing gum for thousands of years.Ancient Greeks,Mayas,and Native Americans,for example,chewed on the sap,or resin of certain types of trees.Today gum is a litde more complicated.Gum manufacturers start by mixing resin,wax,and a molecule called polyvinyl acetate to make a gum base.By varying the types and amounts of these ingredients,scientists can make thousands of formulations. Just what can gum do for your health?Many studies show that chewing gum after meals fights cavities by stimulating the production of saliva.Saliva helps wash away bacteria that damage our teeth.An ingredient called xylitol,which is added to it,provides an extra dose of cavity-fighting power.This is good for more than just the teeth.Research suggests that good oral health decreases the risk of heart disease,and other serious diseases. Chewing gum might also be good for your brain.Chewing gum boosts the flow of blood to participants'brains by 40 percent. But too much chewing can damage the jaw joint.And chewing too much of gum that contains vitamins,caffeine,or a medicine could lead to an overdose.What's a more,no matter how healthy gum chewing proves to be,it will never be a match for a healthy lifestyle.

mmlu_train_52339 | American doctors have been trying to figure out the secrets behind Asians being healthier than Americans since the early 90s - The Japan has the lowest mortality rates in the world and Chinese medicine has been around for thousands of years, since around 2000 B.C. only meant that there's more to Asian health philosophy. In Asian medicine, there's an acknowledgment of the whole-body theory of medicine, instead of isolationism that's prevalent in many American doctor's offices. The main reason behind a better health lies in the difference between Asian and American culture. Diet, exercise, and a holistic approach to medicine all contribute to Asians living longer and healthier than their American counterparts. In addition, the result of the Asian lifestyle has led to a stronger overall immune system and better detoxification efficiency. The more preferred drink in the American lifestyle is soda, beer or coffee. However, in Asian culture, the preferred drink is water or herbal tea. Consumption of water serves to immediately strengthen one's body detoxification program, since water dilutes toxins and helps flush the body. Americans savor red meat and pork, while most Asians prefer chicken, rice and fish. Also, the foods in Asia are mostly organic and lack the hormonal toxins that American food carries. Overall the Asian diet leads to less food-introduced toxins into the body, and allows the body to spend its energy on its immune system rather than toxin control. Also, the fish that Asians consume have very strong immunological effects, providing more antioxidants than the red meat preferred in America. The average American family has more than one car. In Asia, on average there's 1 car per 4 families. In Asian cultures, people use bicycles more than four-wheeled transportation. The Asian lifestyle also involves more labor and physical work, such as agricultural labor and gardening. The American lifestyle praises white-collar jobs which lead to Americans sitting in front of computer screens for hours on end. Exercise helps detoxification in two ways: it speeds up metabolism, and induces sweat. Medicine in Asia centers mostly on natural ingredients that have healing properties. Asian medicine also addresses the mind-body connection and the importance of mental balance. There are more traditional medicine doctors per person in Asia than in America. American medicine costs more and is symptom-focused, often ignoring the overall cause of the symptoms. In America, the prescriptions that are chemically derived are dangerous toxins that stress the body's detoxification system. Using Asian medicine means using only natural ingredients, which the body can easily detoxify while getting the same health benefit. It is not very difficult to adopt the Asian lifestyle and improve your body's detoxification and immune system. You can change your lifestyle today by eating and drinking organic, exercising rigorously at least three times a week, and using organic health alternative therapies over dangerous prescription medicines. ks5u Emma Deangela is the author of detox and fasting site at eDetoxify.com. Combining both Asian and Western philosophy, Emma Deangela has helped many people by giving them health consultation to make their lives better and healthier through natural health philosophy.

mmlu_train_23141 | The average college student in America spent an estimated seven hundred dollars on textbooks last year. The National Association of College Stores reported more than five billion dollars in sales of textbooks and course materials. Association spokesman Charles Schmidt says electronic textbooks now represent just two to three percent of sales. But he says that is expected to reach ten to fifteen percent by 2012. Online versions are now available for many of the most popular college textbooks. E-textbooks can cost half the price of a new print textbook. But students usually lose access after the end of the term. And the books cannot be placed on more than one device so they are not easy to share. So what do students think of e-textbooks? Administrators at Northwest Missouri State University wanted to find out. Earlier this year they tested them with five hundred students in twenty classes. The university is unusual. It not only provides laptop computers to all seven thousand of its full-time students. It does not require students to buy their textbooks either. They rent them to save money. The school aims to save even more by moving to e-textbooks. The students in the survey reported that downloading the books from the Internet was easy.

mmlu_train_50415 | _ (from How Do Animals Move?) Many animals scurry up tree trunks to escape enemies or find food. Some live in the treetops. Many of these animals are not only expert climbers, but they also have found interesting ways to get from tree to tree. How Do Animals Adapt?andHow Do Animals Move? are comprehensive explorations of animal adaptations and movement for young readers. Both are part of a 21 book series,The Science of Living Things. InHow Do Animals Adapt?readers learn how animals adapt to survive with respect not only to climate, darkness, food and defenses but also to offspring and people. These adaptations are well explained in double page spreads with examples clearly depicted in photographs and diagrams and developed through their accompanying captions . As the title suggests, movement is the focus ofHow Do Animals Move?Beginning with a description of the explanation of movement, the reader is exposed to the many different ways of animals movement in the air, on land, under ground and in the water. Several unconventional variations (e.g. looping of inchworms, the rectilinear motion of snakes) are included. Once again, the photographs and diagrams plainly support the double page spread discussions of animal movement. The language of both titles is simple enough for young readers without talking down to them. In both books, terminology is featured in . Some of these words are explained in the basic glossary while the majority are explained clearly in the text. Many of these terms provide readers with some fascinating, uncommon words (e.g. brachiation, potassium, skein, and estimate). As do many of Kalman's book, both of these titles have a table of contents, glossary and index which are all enough to introduce young readers to the nature of these tools.

mmlu_train_26886 | Don't worry, be happy and, according to new research, you will also be healthy. It is estimated that over the course of one year, Americans suffer 1 billion colds. But new research shows that all it may take to avoid this common affliction is a positive and upbeat attitude. People who are energetic, happy and relaxed are less likely to catch a cold than those who are depressed, nervous or angry, finds a new study published in the journal Psychosomatic Medicine. Healthy volunteers first underwent an emotional assessment in which they were asked to rate their tendency to experience positive and negative emotions--how often they felt pleased, relaxed, happy, or anxious, depressed and hostile. The subjects were next given a squirt up the nose of a rhinovirus, the nasty little germ that causes colds. Researchers then watched the volunteers to see who came down with a cold and waited to see how the unlucky ill manifested their cold symptoms. "We found that people who regularly experience positive emotions, when exposed to rhinovirus, are ly protected from developing illness," said Dr. Sheldon Cohen, lead author of the study and a psychology professor at Carnegie Mellon University." Increases in positive emotional styles were linked with decreases in the rate of clinical colds, but a negative emotional style had no effect on whether or not people got sick," Cohen said. So how can your emotions influence your health? In simple terms, when the brain is "happy" it sends messages to our organs that help keep the body healthy and sound." It's like a drug that is released by your state of mind and simply changing the state of mind can produce effects on the rest of the body through the nervous system and hormones," said Dr. Neil Shulman, associate professor of medicine at Emory University School of Medicine and author of Doc Hollywood. "Your chance of developing the common cold, pneumonia, or even cancer may very well be decreased by keeping your brain in a healthy state." In addition, happy and relaxed people tend to better health practices than their negative and stressed counterparts. They are more likely to get plenty of sleep and to engage in regular exercise, and have been shown to have lower levels of certain stress hormones. The experiment states that _ | [

mmlu_train_47870 | The marine environment is fascinating to study and work in due to its beauty, richness, and complexity. It covers three quarters of the surface of the Earth, yet we know more detail about the surface of Mars. In the past, it was seen as both an inexhaustible resource and a bottomless sink for our wastes. Yet the increasing pressures of overpopulation, pollution and the threat to our natural environment mean that there is an increasing need for scientists who can understand how it all works, how it affects us, and how we are affecting it from global warming through to the smallest plankton. From local issues to global concerns, we now know that the marine environment is inextricably linked to our lives, and to our future survival. It is an area where much remains to be discovered, and where only a multidisciplinary approach can cover the breadth of issues to be confronted. This is the approach taken on our Marine Environmental Science degree course. This course takes a multi-disciplinary approach to explore and understand the marine environment. After an initial grounding in basic science, optional choices are available in specialist topics such as marine ecosystems and pollution, coastal navigation and oceanography, among others. Our new harbor side marine laboratory is used for some of the specialist lectures, laboratory and project work, while a week's residential field course in the Isle of Man provides training to prepare for the research project conducted in your final year.

mmlu_train_21458 | Imagine what you could do with a machine that could make things disappear. For inspiration, you could read some books. In the books of J.R.R. Tolkein, Bilbo Baggins finds a ring that can make him disappear. Of course, there's also poor Harry Potter, who used his invisibility cloak to hide from danger. Now that you've got some ideas, it's time for the hard part: building the cloak. To do that, you have to give up science fiction and turn to real science. An invisibility cloak has to cheat anything or anyone who might be watching. In order to understand how something can be seen, it's important to understand how we see. Human beings can only see objects that reflect light waves. These waves enter the eye and are then processed by the brain. However, if an object doesn't reflect light, then the waves don't enter the eye, and the brain doesn't process. So building an invisibility cloak is building something that doesn't reflect light. Cummer was part of a team of scientists from Duke University, including David Smith and David Schurig, who built the world's first version of an invisibility cloak. They had been inspired by the work of a British physicist, John Pendry. He in May said that an invisibility cloak was possible and Pendry was not the only one thinking about a disappearing act. At the same time, a Scottish physicist, UIf Leonhardt published a paper on building invisibility equipment. "It wasn't easy," says Cummer. "As often happens in science and research, it didn't work very well the first time. That first cloak didn't work like Harry Potter's --- the scientists didn't actually see anything disappear. So the research is still under way. " What can be the best title for the text? | [

Now most English families do not have time for afternoon tea at home, but in the past it was a tradition. However, you can still have afternoon tea at many tea rooms around England. Afternoon tea became popular about one hundred and fifty years ago, when rich ladies invited their friends to their houses for an afternoon cup of tea. Later, they started offering their visitors sandwiches and cakes too. During the tea time, friends talked to each other freely and enjoyed themselves. Soon afternoon tea became very popular in England. The English working people do not have afternoon tea. They have a meal at about noon, and a meal after work, between five and seven o'clock in the evening. This meal is called 'High Tea' or just 'Tea' (The traditional 6 o'clock tea). It's usually takes place early evening. High tea is such a big meal that it has many kinds of delicious foods, such as scones, cakes, buns or tea breads, cheese, cold meats and eggs on toast.

mmlu_train_44174 | I bent down in the shade under a sixty-foot-tall cactus , waiting for them to appear. The time was eight thirty in the morning. For seven mornings I had come to the same distant spot in the Sonoran Desert, in southern Arizona. I was here to watch the roadrunner, a small fast-running bird. I spotted two birds under a bush with red flowers. The roadrunners rushed out from under it. The birds moved rapidly on long skinny legs. Their feathers were brown and black. Their tails were seven inches long. Roadrunners use the tail for balance when running. That day, the roadrunners performed a courtship dance. They ran in wild circles. Suddenly, one stopped and stood still, its round eyes full of light. The second bird took hold of a small stick off the ground and presented it to the first, a gift serving as a symbol of their partnership. I returned to the spot each day, leaving bits of boiled chicken hoping they would return. Roadrunners eat snakes, lizards, mice, beetles, and spiders. Food is in short supply in the desert, so my offerings were welcome. The pair grew used to me. Soon after the pair finished building their nest six white eggs appeared in the nest bowl. In about three weeks, six roadrunner chicks, skin as black as coal, cried for food. Their parents brought food such as fence lizards and stink bugs. They fed their young until they were a month and a half old. Early one morning, a coyote came around, nose to the ground, for fresh bird meat. The roadrunners fearlessly drove the coyote away, but it was soon back. After three attacks the coyote went away for good, tail between its legs. I stopped watching the nest when the little roadrunners, at two months of age, were ready to live on their own. It was hard to break away from "my roadrunner family."

Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made "brain". Leading the robot revolution are industrial robots that work in factories. Industrial robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren't as friendly and bright as those you saw in Star Wars.But, their makers say, today's home robots "walk", sense objects in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect. We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths of light, and hear certain sounds. That's because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can't. To understand what their sensing devices pick up is a hard job.

Our biggest enemies are not terrible diseases. We are our own biggest enemies because we sometimes destroy our own good health. Some of us eat too much, drink too much and smoke too much. And though our reason tells us we should control ourselves, we find it difficult. The fact is that most human beings need stimulation. Who doesn't enjoy a drink after a busy day? Only a smoker knows the pleasure of a cigarette with a cup of coffee. The danger is when these innocent pleasures run our lives and so destroy our health. When you find yourself eating between meals or eating too much rich food, when you can only keep yourself going by taking frequent drinks or by smoking one cigarette after another, then it's time to stop and think what you might be doing to yourself. The funny thing is that when we don't control ourselves, simple pleasures are no longer simple pleasures. All right, I know what you're thinking.

Whether the remedy comes from the warmth and comfort of the soup or from actual cold-fighting ingredients in the meal, it is still up for debate. Chicken Soup: Just the Evidence _ The heat, salt, and hydration provided by chicken soup may actually fight the cold virus. Laboratory studies have shown that ingredients of chicken soup with vegetables could kill viral cells and prevent the growth of new ones. The soup may also provide an anti-inflammatory effect that helps reduce cold symptoms. Unfortunately, the benefits of chicken soup appear to be limited by how quickly the soup leaves the body. There is no indication that chicken soup would help in the prevention of colds, but its use as a remedy for symptoms is common. It is largely a safe remedy with no ill side effects, and scientific evidence points more in favor of its cold-fighting properties than against it. The Downside of Chicken Soup Evidence in support of chicken soup's antiviral properties is not yet solid enough to prove true, reliable medicinal effects. Although the evidence based on personal experiences and existing research seem to support a good effect of chicken soup, a clinical trial would be very difficult to perform. In addition, some people with food allergies or sensitivities to salt may experience ill side effects from chicken soup. Unbroken bones may also lead to a chocking risk, particularly for children.

mmlu_train_41526 | Your friends might be in Australia or maybe just down the road, but they are all just a few clicks away. Life has changed for millions of young people across the world who now make friends online. Whether you use chat-rooms, QQ, MSN or ICQ, you are a member of this group. "I don't often talk with my parents or grandparents, but I talk a lot with my old friends on QQ," said Fox's Shadow, the online name used by a girl student in China. "Most of my classmates use QQ after school." QQ is the biggest messaging service in China. A record from Tencent, the company which developed QQ, shows that 4 million people used it one Saturday night in October. And probably Fox's Shadow was one of them. "I _ on Friday nights, and Saturdays or Sundays when I feel everything around me boring. I usually spend about ten hours chatting online every week," she said. "But I never talk with strangers, especially boys or men." Even though she likes chatting, she is careful about making friends with strangers online. "You don't know who you're talking to. You should always be careful about whom you believe in online." Many people would like to meet offline when they feel they have known someone very well. Fox's Shadow once met one of her online friends face to face. It was a girl who was a football fan like herself and they went to a football match together. A 16-year-old Beijing boy, named Bart Simon online, dislikes QQ users. "I used to chat on QQ, but I found that most people were talking about foolish things," he said. Now he chats online in English, using MSN. "I only chat online because I've got friends in Japan, the US and Singapore," he said. "I want to learn more about foreign cultures." But he spends little time chatting on QQ as he sees it as a waste of time and money. "If you are really addicted to it, sometimes you can't give your mind to your lessons," he said. "And friends in your real life are always more important than those so-called friends you meet online." Fox's Shadow thinks QQ is _ . | [

mmlu_train_58598 | 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. Which of the following about the earlier card is TRUE? | [
"Its owner can change the ID code at will.",
"Its user needn't key in the credit card number.",
"It can record its user's spoken password.",
"It can be used by someone who has stolen it."

mmlu_train_17926 | A third of primary schoolchildren in China are suffering from psychological ill-health as a result of classroom stress and parental pressure, according to a study published on Tuesday. The problem is so bad that urgent measures are needed, warns the study, led by British and Chinese researchers. The investigation surveyed 2,191 pupils aged nine to 12 in nine schools in urban and rural Zhejiang, a ly prosperous coastal province in eastern China. Eighty-one percent of the youngsters said they worried "a lot" about exams, 63 percent feared being punished by their teacher, 44 percent had been physically bullied at least sometimes - with boys likelier to be victims than girls - and 73 percent had been physically punished by their parents. Most of the children complained they struggled to cope with the amount of homework they were assigned. Over one-third reported headaches or abdominal pains - psychosomatic symptoms of stress - at least once a week. The most stressed children reported incidence of aches or pains of four times a week. The investigation, led by Therese Hesketh, a professor at University College London (UCL) Centre for International Health and Development, pointed the finger at extreme competitiveness in China's education system, from the onset of primary school. "The competitive and punitive educational environment leads to high levels of stress and psychosomatic symptoms," the authors say. "Measures to reduce unnecessary stress on children in schools should be introduced urgently." The paper appears in Archives of Disease in Childhood, a peer-reviewed journal of the British Medical Association (BMA). The "urban" setting for the study was Hangzhou, the provincial capital of Zhejiang, while the "rural" setting was a poor county in Quzhou prefecture, in the west of the province. The study highlights some of the complexities that, it says, explain the demands for academic excellence and intolerance of failure. One factor is the country's dramatic rise in prosperity, which has created "previously unheard-off possibilities for upward mobility" and in turn stoked pressures on children to do well at school. Other reasons are China's one-child policy and the Confucian traditions of respect for parents and elders, filial piety, obedience and discipline. "The aspirations of many parents, who had limited educational opportunities themselves are now invested in their only children," it says. Previous studies on school-related stress and its impact on health are few and generally come from Scandinavia. A 2008 assessment among 10- to 13-year-old in Sweden found that 21 percent of boys of 30 percent of girls experienced headache, and 17 percent of boys and 28 percent of girls experienced abdominal pain at least once per week. What can we infer from the passage? | [

mmlu_train_41610 | Electronic book publishing has many of the same risks and opportunities as electronic music publishing. By delivering text direct to the user's computer screen, the e-book could cut down costs, and allow creators to deal directly with their audience, bypassing traditional publishers and readers. But it also raises the possibility of mass piracy . Phil Rance, founder and managing director of Online Originals, a London-based e-book publisher, sums it up. "No one wants Napster to happen to books." Indeed, the most popular MP3 have put the frighteners on an industry that generally operates some way behind the "bleeding edge". The Mata Group, a leading US-based market researcher, says publishers are far too concerned about protecting their rights, "We believe all the recent legal control over Napster is like putting a finger in a river that is already overflowing. Publishers need to deal with reality and come up with new ways to develop wide electronic distribution , asking the question: 'How can we use the certainty of wide distribution to our advantage?'" At the moment, most publishers would like to limit the use of e-books to the person who bought them, or to the computer used to download them. If that can be done, e-books become just an extra income stream in a publishing industry that would continue to operate the way it does today, according to Terry Robinson, business manager for Adobe's e-paper group. "If you've cracked digital rights aspect, you've cracked the market," he says. Robert Nichols, Books Director at BOL agrees, "Rights management is absolutely important. Publishers just say that 'until copyright is secure, we're not going to talk'." What do publishers care most about e-books? | [

mmlu_train_25803 | We know that cigarette smoking kills. So, producers made electronic cigarettes as a safer smoking choice - safer than tobacco. Although e-cigarettes contain the drug nicotine like cigarettes, they do not use tobacco and you do not light them. They are powered by battery . However, if e-cigarettes are so safe, why has the United States Center for Disease Control(CDC) seen an increase in telephone calls about e-cigarette poisonings? The answer is children. Most of the calls are from people worried about children who have played with the devices, In the period of one month this year, the Center said 215 people called the Center with e-cigarette concerns. More than half of these calls were for children aged five and younger. The devices had made them sick. Tim McAfee is director of the Center's Office on Smoking and Health, He says the problem is regulation. Meaning, the U.S. federal government does not control e-cigarettes even though they contain liquid nicotine. Mr.McAfee adds that liquid nicotine is a well-known danger. Mr.McAfee explains that nicotine poisoning happens when it gets into the skin, gets into the eyes or is swallowed. It can cause stomach pain or a sense of unbalance. And too much nicotine can kill, Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do.He notes that almost 500,000 Americans die each year from cigarettes. "So, cigarettes are the winner in that contest." E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes. So, the U.S.Surgeon General Boris D. Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use. But McAfee worries that teenagers may think electronic cigarettes are harmless. They could become addicted to the nicotine and then start smoking real cigarettes. In other words, he fears that for young people fake e-cigarettes could be a "gateway" to the real thing. Why did the CDC receive so many calls about e-cigarettes? | [
