mmlu_train_22887 | Americans love peanut butter. The average child will eat 1,500 peanut butter before he or she graduates high school. But there is a controversy over a new peanut butter. It is called STEEM Peanut Butter. This peanut butter adds a new ingredient: caffeine . Coffee is a popular morning drink because it has caffeine and gives people energy in the morning. Even small amounts of caffeine can be dangerous to children. United States Senator Charles Schumer says."Peanut butter, one of the snacks most closely connected with children, might have to be stored in the medicine cupboard rather than in the kitchen cupboard. This will shock the Food and Drug Administration." Schumer wants the U.S. FDA to investigate. He observed that earlier the FDA prevented plans for a caffeinated chewing gum. STEEM, the manufacturer, said, "We are selling the caffeinated peanut butter all over the world. The product provides caffeine in an easily digestible way. Caffeinated foods have been sold in U.S. stores for well over a decade and are in no way a new idea. Customers tell us they want to eat the caffeinated peanut butter so they don't have to drink as much coffee or energy drinks. The peanut butter is not intended for children." "Peanut butter has been a favorite of children for generations," Schumer continued: "Parents across the country have to worry about a scene in which their child might unknowingly bite into a peanut butter that contains more caffeine than two cups of coffee." The American Academy of Pediatrics says caffeine in small amounts can help the physical performance of adults. But the academy urges parents not to allow children to take even small amounts of caffeine owing to caffeine's possible negative effects on a child's heart and brain development.

mmlu_train_23105 | A lot of people say math is not their strong suit. One New Jersey parent wants to help change that. Laura Overdeck grew up with numbers. She always helped measure ingredients when her mother baked, and she learned about angles from her father. She went on to major in astrophysics in college. Overdeck knew she wanted her own children to be good at math, too. "And when our first child was about two, we just started giving her a math problem every night," Overdeck said. The problem was usually a story, involving animals, cars or candies that let the kid count. "Our third child started, at age two, yelling that he wanted his own math problem because he saw his brother and sister doing it. And we thought, 'Wow, we have a household where math is the popular thing at bedtime,'" Overdeck said. In February, Overdeck launched Bedtime Math, an Internet website where she posts daily puzzles for children. Overdeck is particularly keen to hook children on numbers before they go to school. So why introduce little ones to math so early? Sain Beilock, an expert on performance anxiety, says the more fun and familiar math is early on, the less likely children will feel nervous when they start to learn math in school. "My lab has shown recently that kids as early as first grade report feeling anxious about doing math," Beilock said. "You can hear totally educated adults say, 'You know I'm just not that good at math.' or 'I'm kind of afraid of math.' And that's a totally acceptable thing for a well-educated person to say, but you never hear them say, 'Well, you know, I'm just not that good at reading,'" Overdeck said. She wants children and their parents to become as fluent in numbers as they are in Harry Potter. Beilock's attitude towards Overdeck's idea is _ . | [

mmlu_train_38727 | Workers who commute by car, bus or train to the office are more likely to suffer from stress and exhaustion, according to a study. Scientists studied 12,000 employees aged between 18 and 65.They found that those who traveled to work by car or public transport reported higher levels of stress and tiredness compared to active commuters who traveled by foot or bicycle. The negative health of public transport users increased with journey time. It is now expected that the study, from Lund University in Sweden, will encourage further investigation into the health effects of commuting and the best forms of transportation. Researcher Erik Hansson said:"Generally car and public transport users suffered more everyday stress, poorer sleep quality, exhaustion and felt that they struggled with their health compared to the active commuters." According to the Office for National Statistics, the average Briton commutes 54 minutes every day. But now the scientists claim that the advantages of daily travel, such as higher pay or housing conditions, need to be weighed against the negative health effects. Income, family background and environmental factors are other things that need to be considered. It may also have a cost effect on industry. According to a Absence and Workplace Health Survey, the U.K. economy lost 190 million working days to absence last year, with each employee taking an average of 6.5 days off sick, costing employers US$27 billion. Hansson added that findings would help to reconsider the balance between economic needs, health, and the costs of working days lost. However, researchers stress that the findings, published in the journal BMC Public Health, do not prove that commuting causes ill health and further research is needed. The supporters of daily travel will insist that it brings _ . | [

mmlu_train_90480 | In fall 2006,the National Basketball Association (NBA)started using basketballs made with synthetic ,or man-made ,material instead of leather .They made the change be- cause they wanted every basketball they use to feel and bounce the same.Not all leather balls are exactly alike in weight or how they bounce,but the synthetic balls are. 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. Why were the synthetic balls expected to be used in NBA according to the text? | [

mmlu_train_16791 | The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures from the earth. This idea may sound like something from a science fiction , but it is actually being taken seriously by many researchers. This suggests the future for the "red planet" will be the main topic for discussion at an international conference hosted by NASA this week. Leading researchers as well as science fiction writers will attend the event. Turning Mars into a little earth has long been a topic in science fiction," said Dr Michael Meyer, NASA's senior scientist for astrobiology ."Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars." Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal. But many experts are shocked by the idea. "We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet," said Paul Murdin from the Institute of Astronomy, Cambridge, UK.

mmlu_train_34650 | Dogs have an amazing sense of smell thanks to 300million smell receptors in their noses, compared to only five million in the human nose. Medical dogs are trained by smelling samples of people already diagnosed with cancer and those of people without the disease so they can learn to tell the difference. Dr Claire Guest began training her dog Daisy to smell out the killer disease in urine and breath samples when she was young. So far Daisy has found cancer in 551 patients, of which 93 per cent were accurate. And she discovered Dr Guest's breast cancer before it was diagnosed- the first time she has discovered the disease actually growing in someone's body, rather than by smelling a sample. Dr Guest, 50, chief executive of charity Medical Detection Dogs, said: "She pushed against my body with her nose repeatedly - I pushed her away, but she pushed against me again, clearly upset. She pushed me so hard that it hurt me. "Her behaviour was totally out of character - she was normally such a happy dog ... I felt the tender area where she'd pushed me, and over the next few days I discovered the tiniest lump . "If it wasn't for Daisy it would have gone hidden for much longer and could have been more serious," Dr Guest added. "My own pet labrador saved my life." Animal rescue charity Blue Cross presented Daisy with a medal for her achievements. She faced tough competition, including JJ, a bomb detection dog who has saved soldiers' lives in Afghanistan. Steve Goody, the charity's deputy chief executive, said: "Cancer affects the lives of thousands of people and Daisy has made a huge contribution to the diagnosis and early treatment of cancers - she's a very deserving medal _ t."

mmlu_train_12950 | Any foreigner who has tried to learn Chinese can tell how hard it is to master the tones required to speak and understand.And anyone who has tried to learn to play the violin or other instruments can report similar challenges. Now researchers have found that people with musical training have an easier time learning Chinese.Writing in the online edition of Nature Nenroscieme, researchers from Northwestern University say that both skills draw on the same parts of the brain that help people discover changes in pitch . One of the study's authors, Nina Kraus, said the findings suggested that studying music "actually tunes our sensory system".This means that schools that want children to do well in languages should hesitate before cutting music programs.Dr.Kraus said.She said music training might also help children with language problems. Mandarin speakers have been shown to have a more complex encoding of pitch patterns in their brains than English speakers do.This is because in Mandarin and other Asian languages, pitch plays a central role.A single syllable word can have several meanings depending on how it is _ . For this study, the researchers looked at 20 non Chinese speaking volunteers, half with no musical background and half who have studied an instrument for at least six years. As they were shown a movie, the volunteers also heard an audio tape of the Mandarin word "mi" in three of its meanings: squint, bewilder and rice.The researchers recorded activities in their brain stems to see how well they were processing the sounds.Those with a music background showed much more brain activities in response to the Chinese sounds. The lead author of the study, Patrick C.M.Wong, said it might work both ways.It appear? That native speakers of tonal languages may do better at learning instruments.

mmlu_train_32738 | Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives -either recorded or real-may even prevent elephants from damaging farmer's crops. In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away. Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next,Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family. From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place. Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away. Why did Lucy throw a stone into a wild beehive? | [

mmlu_train_58964 | Swearing can provide effective relief from pain - but not if you swear all the time, researchers have found. A study found releasing the strange expletive (=swearing) helped people cope with discomfort in the short-term but the frequency of swearing played an important role. Researchers at Keele University's School of Psychology employed 71 undergraduates who were asked to carry out a cold-water challenge while either repeating a swear word or a non-swear word. The students put their hand in room temperature water for three minutes to act as a control before diving it into cold 5degC water for as long as they could while repeating their word. The level of sensed pain together with a change in heart rate were compared while people swore or said their non-swear word. The group was also asked about how much they swore in daily life and this was analyzed together with their level of pain tolerance. Writing in the Journal of Pain, the authors concluded: "Swearing increased pain tolerance and heart rate compared with not swearing." "Moreover, the higher the daily swearing frequency, the less was the benefit for pain tolerance when swearing, compared with when not swearing." Dr Richard Stephens, a senior lecturer in psychology at Keele, said: "Swearing is a very emotive form of language and our findings suggest that using swear words moderation (, ) can be an effective and readily available short-term pain reliever." "However, if you're used to swearing all the time, our research suggests you won't get the same effect." What's the best title of this passage? | [

mmlu_train_7690 | Living with physical disabilities can be challenging in all kinds of ways.But different from what most parents think, physical disabilities are no barrier to a child enjoying all the benefits that healthy exercise and outdoor play can bring.The importance of exercise has been stressed in recent years as the problems connected with being too fat and poor mental health become ever more widespread.Being physically disabled does not mean that a child cannot be affected by these problems.And being active is a natural and fun way of preventing problems like these from having a bad influence. A swimming pool is one of the best places possible for physically disabled children to enjoy themselves.With proper support,whether from parents or from correctly trained professionals,children can get great benefits from being in the pool.The water provides both support and resistance ,giving a cardiovascular workout as well as making muscles strong.Being able to feel free in a way that is not possible on land is another benefit of swimming. It is possible to play most ball games with a group of children in wheelchairs.Moving and dancing to music is a great social activity for physically disabled children as well as something parents call enjoy with children.A parent or carer can help the child move in time to music or show movements to the child.Playing a modified form of volleyball with a lowered net means that children in wheelchairs can take part and healthy people can sit on chairs to play with them.

mmlu_train_53408 | A few degrees can make a big difference when it comes to food storage.Foods can go bad if they get too warm.But for many of the world's poor, finding a good way to keep food cool is difficult.Refrigerators are costly and they need electricity. Yet spoiled food not only creates health risks but also economic losses.Farmers lose money when they have to throw away products that they cannot sell quickly. But in nineteen ninety-five a teacher in northern Nigeria named Mohammed Bah Abba found a solution.He developed the "Pot-in-Pot Preservation/Cooling System." It uses two round containers made of clay.A smaller pot is placed inside a larger one.The space between the two pots is filled with wet sand.The inner pot can be filled with fruit, vegetables or drinks.A wet cloth covers the whole cooling system. Food stored in the smaller pot is kept from spoiling through a simple evaporation process.Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving.The evaporation process creates a drop in temperature of several degrees.This cools the inner pot and helps keep food safe from harmful bacteria.Some foods can be kept fresh this way for several weeks. People throughout Nigeria began using the invention.And it became popular with farmers in other African countries.Mohammed Bah Abba personally financed the first 5,000 pot-in-pot systems for his own community and five villages nearby. In 2000, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise.This award recognizes people trying to develop projects aimed at improving human knowledge and well-being.A committee considers projects in science and medicine, technology, exploration and discovery, the environment and cultural history.Winners receive financial assistance to help develop and extend their projects.The award is given every two years.The most recent one was given last year.

But we believe at the beginning of the eighteenth century there were 105,000 humpback whales and 120,000 right whales. At the beginning of the twentieth century there were 75,000 humpbacks and 80,000 rights. Since 1900 their numbers have fallen very quickly. Between 1935 and 1950 the number of humpbacks fell from 20,000 to 10,000 and since 1950 the number has fallen to only 6,000. The number of right whales has fallen even faster. In 1935 there were 25,000. The number fell to 6,000 in 1950 and since 1950 the number has fallen to 4,000. Men have always been hunters. Thousands of whales have become victims .

mmlu_train_10672 | The rise in smartphones among young people may be having a direct effect on how successful they become as adults. Research from the University of Nebraska-Lincoln has discovered the average university student checks their phones 11 times per lesson, and more than 80 percent believe this tech addiction is interfering with their learning. A quarter of students across five U.S states also blamed poor grades in exams specifically on the fact they used mobile devices when they should have been concentrating and revising - and these grades could determine the jobs they end up going into. Barney McCoy, an associate professor of broadcasting at the university, surveyed 777 students at six universities across five states about how they used digital devices in the classroom. The students were from UNL and the University of Nebraska at Omaha in Nebraska, Morningside College in Iowa, the University of North Carolina, the University of Kansas and the University of Mississippi. Around two thirds said they used phones, tablets and laptops for "non-classroom purposes" up to ten times during a typical university day, while 15 percent admitted this figure was closer to 30 times. Among the top reasons why students checked their devices so regularly were staying connected and fighting boredom, at 55 percent. Less than half said the devices were used for classwork. Texting was the most popular distraction technique at 86 percent, while 68 percent said they used their phones to check personal emails. Two thirds used social networks, 38 percent surfed the web and eight percent admitted to playing games when they should have been studying. Despite eight out of ten students admitting their devices were distracting, fewer than five percent considered it to be a "very big" distraction. "I don't think students necessarily think it's a big problem," said McCoy said. "They think it's part of their lives." "It's become automatic behavior on the part of so many people - they do it without even thinking about it." He continued, "They've got their laptops open, but they're not always taking notes. Some might have two screens open -- Facebook and their notes." The text is most likely to be found in a section about _ . | [

mmlu_train_42681 | Left-Handers' Day International Left-Handers' Day is August the thirteenth. The International Left-Handers Day, Web site says the Left-Handers Club started the holiday in 1992. It wanted left-handers around the world to celebrate. And it wanted to bring attention to the everyday problems of people who use their left hands. One of these problems is difficulty using equipment and tools, like scissors. In general, most tools and equipment are made for people who are right-handed. The Left-Handers Club tries to educate designers and producers to consider the safety of left-handed people when producing their products. Another problem is that many people have considered it bad to be left-handed. Some teachers and parents have tried to force children who used their left hands to use their right ones instead. Scientists do not really know why some people are left-handed. They have believed the reason is genetic.They say the gene increases the chance of being left-handed. It appears to play an important part in deciding which part of the brain controls different activities. In right-handed people, the left side of the brain usually controls speech and language. The right side controls feelings. However, the opposite is often true in left-handed people. Scientists believe the gene is responsible for this. The gene showed a link with left-handedness in nine to twelve percent of the population. About ten percent of people around the world are left-handed.

mmlu_train_86140 | Dolphins are not fish. They are mammals .They live in groups and speak to each other in their own language. But they are quite different from almost all land animals. Their brain is as big as men's and they live a long life at least 20 or 30 years. Like some animals, dolphins use sounds to help them find their way around. They also use these sounds to talk to each other and to help them find food. They do not use their ears to receive sounds,but use the jaw--the lower part of the mouth. It is strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand,there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903 ,Jack met every boat in the area and showed it the way. In 1903 a passenger on a boat with the name of The Penguin shot and hurt Jack. Luckily the dolphin didn't die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the boat of the Penguin. Today, some people still kill dolphins, but many countries in the world now protect them. In these places, people are not allowed to kill them. Who was Jack? | [

mmlu_train_11297 | Cats like climbing trees and there are logical reasons behind this behavior. Interestingly, due to some of their physical features, cats will meet trouble getting down from the trees after climbing up, which may seem unusual. There are several reasons why cats climb trees, mostly to do with defensive purposes. Cats, as predators , like to understand their environment well. As they are small animals, their scope of vision is considerably smaller. Cats often climb trees to get a better view of their surroundings to help them see any potential dangers. While cats are predators, they are also easy to get attacked from larger animals, such as dogs or even other cats. A tree often provides a safe hiding place. In the wild, cars climb up trees to give them a resting or napping place that is out of predators' range. It also helps disguise their presence. Some cats may climb trees for fun, on occasion, or possibly to work on improving their climbing abilities. Small cats frequently test out their claw skills by trying to climb up anything and everything, from bookcases to trees to a person's leg. Climbing practice is good for cats; it can improve their strength and flexibility and teach them an important defensive skill. If a cat has gotten up a tree and cannot get down, the owner may wonder why its remarkable climbing abilities only work in one direction. A cat's claws curve inward, allowing it to grip onto surfaces while going up head first. Unfortunately, this useful climbing curve does nothing to help the animal get back down again. Eventually, most trapped cats will either jump out of the tree or realize that they can get down by going tail first. Either way, a cat up a tree is usually nothing to worry about; they are intelligent animals and will figure out how to get down sooner or later. What should you do when you see a cat trapped in a tree? | [

mmlu_train_55233 | It can be hard to encourage families of preschoolers to turn off the TV,but there are plenty of highquality shows that promote learning and positive relationships rather than violence,researchers noted. "Although clearly kids watch too much,what's more worrying is that they watch poor quality shows," said Dr Christakis,the lead researcher on the new study from the University of Washington in Seattle.His former survey of parents of threeto fiveyearold children showed the kids often watched violent cartoons and movies that are "totally inappropriate". For their study,he and his colleagues randomly divide 565 preschoolers into two groups.In one group,parents recorded notes about kids' normal TV viewing,without receiving any guidelines to reduce or change those habits.In the other group,researchers made visits and calls and sent monthly newsletters encouraging parents to replace violent TV with educational programming.After six and 12 months,parents reported their kid's angry,aggressive or anxious behaviors on a questionnaire.At both time points,children in the TV intervention program had slightly fewer problems than those in the comparison group.Boys in lowincome families seemed to benefit most from the change in programming,the researchers found. "The point is,this is something that is as effective as other things we do to try to guide behavior in children,and it's fairly simple," Christakis said. Another study published in Pediatrics found the more TV kids and teens watched,the more likely they were to have a crime or other problems in society.Children may imitate violence they see--or more time in front of the TV could simply mean less communication with peers and families,and worse performance in school. The American Academy of Pediatrics recommends kids watch no more than one to two hours of highquality programming each day.Researchers agreed parents should be mindful of what exactly their young kids are watching on TV as well."It's not just about turning the TV off,it's about changing the channel," Christakis said.

mmlu_train_44638 | Rene Descartes' explanation of pain has long been acknowledged in medicine. He proposed that pain is a purely physical phenomenon - that tissue injury makes specific nerves send a signal to the brain, causing the mind to notice pain. The phenomenon, he said, is like pulling on a rope to ring a bell in the brain. It is hard to overstate how deeply fixed this account has become. In medicine, doctors see pain in Descartes' terms-- as a physical process, a sign of tissue injury. The limitations of this explanation, however, have been apparent for some time, since people with obvious injuries sometimes report feeling no pain at all. Later, researchers proposed that Descartes' model be replaced with what they called the gate control theory of pain. They argued that before pain signals reach the brain, they must first go through a gating mechanism in the spinal cord . In some cases, this imaginary gate could simply stop pain signals from getting to the brain. Their most _ suggestion was that what controlled the gate was not just signals from sensory nerves but also emotions and other "output" from the brain. They were saying that pulling on the rope need not make the bell ring. The bell itself--the mind-- could stop it. This theory led to a great deal of research into how such factors as mood, gender, and beliefs influence the experience of pain. In a British study, for example, researchers measured pain threshold and tolerance levels in 53 ballet dancers and 53 university students by using a common measurement: after immersing your hand in body-temperature water for two minutes to establish a baseline condition, you put your hand in a bowl of ice water and start a clock running. You mark the time when it begins to hurt: that is your pain threshold. Then you mark the time when it hurts too much to keep your hand in the water: that is your pain tolerance. The test is always stopped at 120 seconds, to prevent injury. The results were striking. On average female students reported pain at 16 seconds and pulled their hands out of the ice water at 37 seconds. Female dancers were almost three times as long on both counts. Men in both groups had a higher threshold and tolerance for pain, but the difference between male dancers and male nondancers was nearly as large. What explains that difference? Probably it has something to do with the psychology of ballet dancers--a group known for self-discipline, physical fitness, and competitiveness, as well as by a high rate of chronic injury. Their driven personalities and competitive culture evidently accustom them to pain. Other studies along these lines have shown that outgoing people have greater pain tolerance and that, with training, one can reduce one's sensitivity to pain. There is also striking evidence that very simple kinds of mental suggestion can have powerful effects on pain. In one study of 500 patients undergoing dental procedures, those who were given a placebo injection and promised that it would relieve their pain had the least discomfort-- not only less than the patients who got a placebo and were told nothing but also less than the patients who got actual drug without any promise that it would work. Today it is abundantly evident that the brain is actively involved in the experience of pain and is no more bell on a string. Today every medical textbook teaches the gate control theory as fact. There's a problem with it, though. It explains people who have injuries but feel no pain, but it doesn't explain the reverse, which is far more common-- the millions of people who experience chronic pain, such as back pain, with no signs of injury whatsoever. So where does the pain come from? _ . The last sentence of the passage serves mainly to express that _ | [

mmlu_train_66904 | Traffic Management Traffic lights are key tools for regulating traffic How.They are not, however, perfect.Drivers exchange the traffic jams that would happen at unmanaged crossings for a pattern of stop-go movement that can still be annoying, and which bums more fuel than a smooth passage would. Creating such a smooth passage means adjusting a vehicle's speed so that it always arrives at the lights when they are green.That is theoretically possible, but practically hard.Roadside signs wired to traffic lights can help get the message across a couple hundred metres from a crossing, but such signs are expensive, and are not widespread.Margaret Martonosi and Emmanouil Koukoumidis at Princeton University, and Li-Shiuan Peh at the Massachusetts Institute of Technology, however, have an idea that could make the process cheaper and more effective.Instead of a hardwired network of signs, they propose to use mobile-phone applications. For a driver to benefit, lie must load the team's software , named SignalGuru, into his phone and then put it on a special thing attached to the inside of his car's windscreen, with the camera lens pointing forward.SignalGuru is designed to detect traffic lights and track their status as red, yellow or green.It broadcasts this information to other phones in the area that are fitted with the same software, and --if there are enough of them ?the phones thus each know the status of most of the lights around town.Using this information, SignalGuru is able to calculate the traffic-light schedule for the area and suggest the speed at which a driver should travel in order to avoid red lights. Tests in Cambridge, Massachusetts, where five drivers were asked to follow the same route for three hours, and in Singapore, where eight drivers were asked to follow one of two routes for 30 minutes, revealed that SignalGuru was capable of predicting traffic-light activity with an accuracy of 98.2% and 96.3% respectively, in the two cities.This was particularly impressive because in Cambridge the lights shifted, roughly half-way through the test, from their unbusy schedule to their afternoon-traffic schedule, while in Singapore lights are adaptive, using detectors fixed under the road to determine how much traffic is present and thus when a signal should change.In neither case was SignalGuru fooled. Fuel consumption fell, too --by about 20% .SignalGuru thus reduces both annoyance and fuel use, and makes going back and forth to work a slightly less horrible experience. With the information it collects and processes, SignalGuru is able to _ . | [

So what do students of your age eat for lunch at school? Japan High schools have canteens,which serve everything from noodles to rice,but not burgers and chips.Other children bring food from home such as cold rice balls,meat or fish,pickles and vegetables. The United States A typical menu from a US school is made up of a hamburger with fried potatoes or roast chicken,lettuce and pickles,fruit and cookies.School lunches must also provide at least one-third of the daily dietary allowances of protein ,vitamin A.vitamin C,iron,calcium,and calories . Australia Meat pies,sausage rolls and hotdogs are all traditional dishes in Australian school shops.But as the nation pays more attention to children's health,healthier foods have started to find their way onto school menus. Many schools have used a traffic light system.The sale of red-labelled foods including pastries,chocolate and soft drinks,is served only twice a week.Healthier green-labelled foods such as sushi,sandwiches,corn and watermelon,however are served every day. In some schools.students have a choice of up to 89 foods to choose from,including popcorn and rice. South Africa Most of South Africa's schools do not serve meals at all.Classes end at 1:30 pm and students get their own lunches.Many students bring food from home,usually sandwiches. Fast food and fried food sell the best among students,which has led to a rise in obesity among children.But as more people began to realize the fact that being too fat may cause different diseases,some schools in towns have led the way towards better nutrition .Now students at these schools are provided with lunches of porridge with vegetables,such as cabbages,onions,beans,carrots and tomatoes.

mmlu_train_18727 | Internet use appears to cause a drop in psychological health, according to a research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who used Internet less frequently, the two-year study showed. And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling. Researchers are puzzled by the results, which were completely the opposite to their experiences. They expected that the Net would prove socially healthier than television, since the Net allows users to choose the information and to communicate with others. The fact that Internet use reduces time available for family and friends may explain the drop-in well-being, researchers supposed. Faceless, bodiless "virtual" communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that knowing the wider world via the Net makes users less satisfied with their lives. "But it's important to remember this is not about the technology; it's about how it is used," says psychologist Christine Riley of Intel, one of the study founders. "It really points to the need for considering social factors in terms of how you design applications and services for technology." Why did the results of research puzzle the researchers? | [

mmlu_train_17696 | The organization representing British universities has expressed concern about the potential effect of tuition fees after figures showed a drop of more than 6% in student applications with less than a month to go before the deadline for 2013 applications. Data from the Universities and Colleges Admissions Service (Ucas) showed there were 265,784 university applications by UK-based candiates up to 17 Decemeber, 6.3% down on the parallel period in the admissions cycle the year before. While this is less than the 8.4% year-on-uear fall seen in earlier Ucas figures, released in mid-November, the coming January deadline makes it ever more likely that the total 2013 applicant figure will see a second sizeable fall following the introduction of annual fees of up to PS9,000. Nicola Dandridge, the chairman of Universities UK, said : "However, we must be concerned about any drops in the numbers applying to university and in particular, we must look closely at how the increase in graduate contributions in England may be affecting the decisions of promising students. However ,the December figures show a drop in numbers across the UK, suggesting that it is not only a question of tuition fees in England putting off from applying." A report of the Uncas figures to mid-December shows a 6.5% fall for applicants in England and 11.7% for those in Wales, with smaller drops of 3.9% for Scotland and 0.5% for Nortern Ireland. Scotiish students at home insitiutions pay on fees, while those from Nothern Ireland have fees capped to PS3,575 for Northern Irish universities. Dandridge added: "No one should be put off applying to university because of worries about finance." "It is important that no one is put off applying to university because they do not have information about the student support available to them. Most new students don't need to pay directly. There will be more financial support for those from poorer families and everyone will make lower loan repayments thatn they do now once they are in well paid jobs."

mmlu_train_64850 | I am a vegetarian . Many people are quick to think of vegetarianism as strange behavior. I treasure our Earth, and since we only have one, we should protect it and the wildlife that lives on it. But that's only one of the reasons to be a vegetarian. Vegetarians may live longer, healthier lives. There is a connection between red meat consumption and various diseases. From an economic standpoint, it requires less land, money and energy to produce foods for a vegetarian diet. While there are many benefits to being a vegetarian, only a handful of those who attempt to adopt this lifestyle succeed. The most important quality required to be a vegetarian is firmness since surrounded by the _ of meat, we tend to give up vegetarianism easily. Creativity is almost as important as commitment. It's easy to tire of eating nothing but salad. But with a little creativity and some soy products, almost any meal can become vegetarian-friendly. Not everyone wants to be vegetarian. Accepting this is part of being a vegetarian with style. Forcing your beliefs on others is disrespectful. Stylish vegetarians should also be able to turn down a meaty dish politely without annoying their hosts. Being a successful vegetarian has been easy for me, but it may not be so for others. A common mistake is quitting before your body has adjusted to the change. It can be difficult to keep the lifestyle in the beginning because of temptation. However, it fades over time. Another common mistake is quitting because you've been misinformed about the nutritional wisdom of being a vegetarian. That's why it is vital to be educated. Countless people will tell you that it's impossible to obtain the nutrients and protein your body requires without meat, but they are incorrect. People actually need only 44-55 grams of protein a day, and that is easily found in a vegetarian diet. Many meat eaters are consuming three times that amount, which is not beneficial. It leads to diseases. Vegetables can also supply all the vitamins, minerals and nutrients your body needs. However, if you're still not convinced, you can take a multi-vitamin. Which of the following is NOT true? | [
"Many people give up before their bodies can adjust to the transition.",
"Many people quit because they're poorly educated about nutrition.",
"Consuming 150 grams protein a day can be harmful.",
"Vegetarians need multi-vitamins to keep healthy."

mmlu_train_10599 | If you were on the street in Mexico today you might think you were in an operating room, surrounded by doctors. You could see many concerned people with masks trying their best to stop the swine flu . And the masks aren't only being used in Mexico. A friend of mine traveling from New York City to Florida was given a mask and a pair of gloves just after he reached the airport. And another friend went to get a haircut only to be faced with a hairdresser wearing a mask! But do the masks really work? Is covering your nose and mouth the key to stopping the swine flu? To find out the truth, ABC's reporter Sharyn Alfonsi talked with germ expert Dr. Elaine Larsen. It turns out that when you sneeze the air coming out of your mouth at a speed of one hundred miles per hour carries germs which can travel anywhere around you and make people around you infected . However, whether you become infected actually depends on the weather. As Sharyn reported, when you sneeze, the germs leave your body in small drops of water coming out of your mouth. If the weather is wet, the wet air will make the small drops bigger and heavier and they drop down towards our feet. If this happens, we won't become infected. But if the air is dry, those small drops can float higher up, making it possible for them to touch someone else's nose, mouth or their mask. Larsen says the masks can stop the germs well but after a few hours, they start to get wet, holding a lot of germs they come across and causing you to breathe them in. The masks do work, but the key to stopping the germs is changing your masks often. According to Para.1, in Mexico you can see that _ . | [

mmlu_train_45382 | Are you carrying too much on your back at school? You're not alone. Back experts in the USA were worried that young students are having back and neck problems because they are carrying too much in their backpacks (schoolbags). "It hurts my back when I run," said Eglin Reyes, a student in Virginia. "It's hard to get up the stairs with my backpack because it's too heavy." Students have to carry heavy backpacks on their backs for a whole week's study. Beeline is one of them. They have regular backpacks with two straps to carry them, but a number of students with heavy loads have switched to rolling backpacks. The backpacks have wheels and can roll on the ground. Shirley Park's backpack weighs 10 kilos, and she said, "I'll change to a rolling backpack because I am starting to have back pain." How much is too much? Experts say that students should carry no more than 10 to 15 percent of their own body weight. A few students have had a good idea to lighten the load: Less homework. Doctor's suggestions: *Lighten the load. Take home only the books the students need that night. *Wide straps are better. They can send out weight over your shoulders and be sure to wear backpacks with two straps. *The heaviest things should be packed closest to the back. *Bend both knees when you pick up the pack, don't just bend the waist .
