mmlu_train_51826 | Let's say you took violin lessons all through elementary school, but you haven't got the instrument out of its case for years. Were all those lessons a waste of your parents' money because you didn't become a violinist? Even though it has been a long time since you played the violin, a new study shows that as little as one year of music training can have a positive impact on your brain that will last the rest of your life. In an experiment, researchers compared children who had taken music lessons to those who hadn't. Laurel Trainor, who studies music and the mind, discovered that the musically-trained children had better brain responses in certain sound recognition exams. Trainor's findings show the possibility that musical education can actually improve the brain's hearing cortex . "The study's results show that music training affects attention and memory, and helps children develop learning skills. In this way music training might lead to better learning across a number of fields," Trainor said in a statement. The effects of music education are even more obvious on children with difficulty in reading and writing and other language-related disabilities. So, whether you can play a good piece of music or not, it's likely that your years of music lessons have prepared your brain for all the speeches, emails, and adult conversations that are part of your life today. We should help make sure that children today have the same opportunities for music, and help out by volunteering with or donating instruments to your school's music education department. What can we learn from the text? | [

mmlu_train_58808 | With only a click of the mouse, rumours can be forwarded between microblogs very quickly. As an example, recently, sensitive netizens discovered that some photos displayed on microblogs describing Beijing's June rainstorm had actually been Sina.com is one of the major Internet portals in China with hundreds and thousands of users, and a majority of celebrities and famous citizens have their microblog accounts on this portal. As recently as six months ago, the website decided to establish a specialized team to prove rumours and provide accurate information for its users. Tan Chao is in charge of the team. " Before I took the job, I usually couldn't identify what information was real and what was fake. But during the process of identification, we discovered that a lot of information was false, including fake photos, fake news stories and rumours that had been spread through microblogs." It's not just website portals which are taking on fact-checking responsibilities, but also a number of civic-minded netizens, who recently set up a Rumour Identification Federation on Sina.com's microblog system to help netizens identify fake information online. Dian Zizheng is the team leader of the federation. He says they've publicized more than 150 pieces which contradict rumours, which attracted more than 10 thousand visitors within two months. "We live in an age of new media, so we can't use the old methods to prove rumours. We can't wait for the media to prove the facts with related administrative departments and then release a formal announcement. We can't allow rumours to run wild and then deal with it, we need to fight rumours while they're spreading. I think that this is the best way to deal with rumours nowadays." Some experts say this displays the advantages of the internet compared to other traditional media. The open platform allows information to be examined and clarified by netizens. But experts like Ding Wengguo,President of the Journalism and Communication College at the China University of Political Science and Law says this self-correction function of the Internet is still quite limited. "It's still quite different to tell which information is true in such an open environment by just reading a number of different opinions on the same issue. This is something which we need to pay attention to. If society is flooded with too much false information, and it's allowed to spread in such a fast manner, then people will be suspicious of all kinds of information including important information from authorities. It also worsens problems relating to social communications and mutual-understanding, which in turn harms society as a whole." Experts suggest that the government should react more quickly in the Internet age. Once a rumour begins to spread, administrative departments should make announcements as early as possible to drive away rumours before they lead to bad outcomes. Which of the following is true according to the text? | [

mmlu_train_38928 | Two new studies suggest that modern running shoes could increase the risk of injuries to runners. One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine . Sometimes they wore running shoes. Other times they ran barefoot . Researchers from the JKM Technologies company in Virginia, the University of Virginia and the University of Colorado did the study. They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels. The study appeared in the official scientific journal of The American Academy of Physical Medicine. The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland. They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running. Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel. Harvard's Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings. But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured. The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website. What can we learn from the passage? | [
"The way that we run by landing on the front or middle of our foot could avoid damaging our heel.",

mmlu_train_67005 | Vans, Keds, Dollies--they sound like the names of rock bands, but if you have teenagers, you'll know they're actually the latest in teenage footwear. But experts are now warning that the current shoe fashions will be causing teenagers discomfort in the short term and storing up years of foot, knee and back pain in the future. Here, the experts identify the problems caused by teenagers' shoe choice. KEDS/VANS Slip-on shoes with elastic sides are particularly popular among teenage boys-with Keds and Vans the most sought-after brands. The main problem is that they are just too flat--so flat that the heel, which strikes the ground first, also becomes damaged and painful. BALLET PUMPS The worst shoes of all are such light and thin dolly shoes. The problem is partly their flatness, as with Keds and Vans. However ballet pumps, which have no string or heel, have other specific problems. "As the shoe has no fastening device, it relies on the toes to keep the shoe on, causing an awkward gait ,this leads to short-and long-term problems such as calluses ,heel and knee pain." WEDGES AND STILETTOS These shoes can also cause problems with gait, They may look good, but the heels on these are so high they can force the wearer's body weight forward, making them very unstable. Teens who wear these shoes regularly are also in danger of joining those millions of women with constant back pain. SCHOOL SHOES So what do podiatrists have on their wish list, especially for everyday wear? Something in a natural, breathable fabric, with a string to hold it on, with a small heel and a deep toe-box that does not press the toes, such as Clark's, Marks & Spencer or Rhino. If your teen insists on wearing 'bad' shoes, get them some simple foot orthotics in the shoes. These support and correct the movement of the foot and, properly fitted by a podiatrist, can often transform their walk and halt the damage.

Or you've got tickets booked for a Caribbean cruise , but your passport disappeared. Or maybe you've just come back from a grocery store tour and realized...Hey, did I leave my baby in the checkout line? Ok, you've probably never gone to the extremes of our last example (we hope), but most of us experience slip - ups like these on a daily basis. No matter how smart you may be, it doesn't mean your brain won't turn to Swiss cheese every so often, and no amount of e-mail reminders can help you remember where you left your TV remote or lucky penny. But now, there is a new pair of eyeglasses that can help to find all those little things you know must be around somewhere : Let's call it Vision 2.0. The new glasses, which are being developed in a Japanese lab under the code name Smart Goggles,are similar to a Google search engine for your eyes. The high - tech glasses come with a camera that records everything you see on a daily basis, and boast built - in object recognition software that allows them to keep track of whatever comes across their field of vision. If you've got a collection of art sculptures that the camera can't recognize immediately, no problem : Just say the name of each item, and the glasses will memorize them right away. The Smart Goggles' superb tracking abilities mean that whenever you're looking for your keys, your overdue library book, or yes, even your baby, all you have to do is to say the word and the Goggles' camera will show you the last time your desired object appeared on screen, telling exactly where you'll be able to find it. Though the glasses are still too big for general use, the research team in Japan believes that they'll be able to make the modem glasses smaller to the size of normal glasses in the near future, making them the perfect new accessory for yourself or any other absent - minded Professor you know. With these intelligent designs, you'll never lose anything again. Except maybe your glasses. Which of the following statement is true about Smart Goggles? | [

mmlu_train_18834 | Public caught up in argument over safety of genetically modified or simply GM products, report Zhang Lei and Zhong Nan in Beijing. More than 300 people gathered to enjoy a bowl of porridge made from genetically modified food on Saturday, an attempt to quell public fears about the safety of the product. The first China Golden Rice Tasting Event was held at Huazhong Agricultural University in Wuhan, Hubei province, sparking another round in the nationwide debate about the safety of GM crops, often called "Frankenfood" by opponents. Similar events have been held in more than 28 cities since May, the university said. Both the pro and anti camps have posted conflicting comments on the Internet, with each providing evidence to back up their beliefs, but the exchanges are becoming increasingly bitter. Jiang Tao, a senior engineer at the Center for Agricultural Resources Research at the Chinese Academy of Sciences, who is in favor of GM foods, was annoyed about what he called "amateurs" spreading rumors. "Just look at the people who are opposed to GM foods; can you find anyone from a related field in the scientific community?" he asked. Jiang also accused the anti-GM lobby of repeatedly using outdated or inaccurate data to support an "incorrect" stance. Chen Yunfa, an independent researcher into the Yangtze River Delta economy, recently wrote a commentary on the Internet news portal Eastday in which he criticized the actions of the 61 scientists, saying they had gone "beyond their proper duty". He suggested that large multinational corporations might be behind the letter and similar incidents, prompted by a desire to freeze China's patent hybrid rice technology out of the market. To support his contentions, Chen said that GM rice, first produced by scientists in the US, still hasn't gained official approval from the US government. However, the US authorities have actually granted licenses to six varieties of GM rice. The commercial planting of two varieties - anti-herbicide (BAR) transgenic rice LL RICE 06 and LL RICE 62 - produced by the French pharmaceutical company Sanofi-Aventis, was approved in 1999 and a license for cultivation for edible use was granted in 2000. The public outcry for GM labeling and boycotting has hindered the advancement of the technology. Concern about GM foods has been fueled by studies like the one published by French professor Gilles-Eric Seralini in September 2012. Seralini claimed that his research involving rats proved that the GM corn fed to them caused tumor growth. Furthermore, there is growing concern that the pesticides used on GMOs are contributing to the decline of the world's honey bee population, leading to honey bee deaths by infecting the brains of the insects with toxins. Therefore, some experts recommend the labeling of non-GM foods so that consumers can make that decision without a regulatory burden being placed on GMOs. However, we should be cautious about anything that may risk humans' life. Only time will tell. Why did more than 300 people enjoy porridge made from genetically modified food? | [

For the best results, eat within 30 to 60 minutes after exercising, when the muscles are at the best time to take in nutrients. Here are some ideas for meals after exercising. Home-made sports-recovery drink Mix banana, milk, and yogurt to make a fresh and satisfying sports-recovery drink. Dairy products like milk and yogurt work double duty, providing both protein and carbohydrates . A cup of coffee, on the other hand, is a poor choice. Protein-packed sandwich You can't go wrong with a sandwich after exercising --it's got everything in a hand-held package. Sandwiches provide the salt you need to replace what you lost by sweating , while the tomatoes in them supply plenty of Vitamin C. Try using whole-wheat bread to give yourself more fiber. The cheese and fresh vegetables in sandwiches are also great for helping tired muscles recover. Power breakfast An egg sandwich is a perfect post-exercise breakfast. There's protein in both the yolk and the white of the egg. This recipe increases your protein intake while keeping calories and fat under control. Eggs also contain zinc , which helps protect against disease. Plant-based protein Beans are an amazing source of plant-based protein and carbohydrates.

Eighteen-year-old Mach was the youngest person in Poland to receive money from others to develop his company. He started FIVE, a mobile messaging app , for deaf people. The app lets deaf people create their own hand signs to communicate with friends. The app now has more than 10,000 deaf users. And Mach thinks there will be about 150,000 more deaf users next year. Mach says, "I love to create. I will stick to it to the end of my life." William Zhou was born in Beijing and grew up in Canada. He strongly wanted to make a change in education. So he created CHALK. It is a group of programs that supports individual teaching and learning. CHALK is now used in 20,000 schools by more than 100,000 users worldwide. Zhou says you have to find something you truly care about. Or you may just end up giving it up. George was born in Tanzania . He learned about renewable energy in Europe and began thinking about using solar energy in Africa. Tanzania is a place with bright sunshine, but more than 90 percent of people have no electricity to use. After graduation, George returned to Tanzania and started his own company, SunSweet Solar. It has found early success in rural areas. George hopes to create jobs and help build his country. He understands the process will take time. "But I think we are on the right way."

mmlu_train_24480 | They said highly anxious rats which were kept had very low levels of a brain chemical called fibroblast growth factor 2 or FGF2, compared with rats that were more relaxed. But when they improved the anxious rats' living conditions -- giving them new toys to explore and a bigger cage to live in -- levels of this brain chemical increased and they became less anxious. "The levels of this brain chemical increased in response to the experiences that the rats were exposed to. It also decreased their anxiety". Javier Perez of the University of Michigan said in a telephone interview. "It made them behave the same way as the rats that were relaxed", he said. In a former study of people who were severely depressed before they died, the team found the gene that makes FGF2 was producing very low levels of the growth factor, which is known primarily for organizing the brain during development and repairing it after injury. Perez thinks the brain chemical may be a marker for genetic vulnerability to anxiety and depression. But it can also respond to changes in the environment in a positive way, possibly by preserving new brain cells. While both the calm and anxious rats produced the same number of new brain cells, these cells were less likely to survive in the high-anxiety rats, the team found. Giving the rats better living conditions or injecting them with FGF2 helped improve cell survival.

mmlu_train_25393 | French surgeons have performed what they said on Wednesday was the world's first partial face transplant--- giving a new nose, chin and lips to a woman attacked by a dog. Specialists from two French hospitals carried out the operation on a 38-year-old woman on Sunday in the northern city of Amiens by taking the face from a brain-dead woman, who had hanged herself just hours before the operation. Her family agreed on the operation. "The patient is in an excellent state and the transplant looks normal," the hospitals said in a brief statement after waiting three days to announce the pioneering surgery. The woman had been left without a nose and lips after the dog attacked her last May, and was unable to talk or chew properly. Such injuries are "extremely difficult, if not impossible" to repair using normal surgical techniques, the statement said. The statement did not say what the woman would look like when she had fully recovered, but medical experts said she was unlikely to _ the woman who had been the source of her new face. The operation was led by Jean-Michel Dubernard, a specialist from a hospital in Lyon who has also carried out hand transplants, Skin transplants have long been used to treat burns and other injuries, but operations around the mouth and nose have been considered very difficult because of the area's high sensitivity to foreign tissue. Teams in France, the United States and Britain had been developing techniques to make face transplants a reality There was a short-term risk for the patient if blood vessels became blocked, a medium-term danger of her body rejecting the new skin and a long-term possibility that the drugs used could cause cancers. Experts say that although such medical advances should be celebrated, the transplant had thrown up moral and ethical issues. Little is known about the psychological effect of the transplant.

mmlu_train_74607 | Have you ever wondered? 1. Why do airplanes take longer to fly west than east? It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction. 2. What would happen if the gravity on Earth was suddenly turned off? Supposing we could magically turn off gravity. Would buildings and other structures float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string , it goes around in a circle until you let go of the string. Then it flies off in a straight line. 'Switching off' gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly _ upwards at a great speed until they hit the ceiling. Most things outside would fly off into space. What information can we get from the first passage? | [

mmlu_train_19398 | Like people, plants experience stress. And also, like people, the response to that stress can determine success. Bad environmental conditions, such as drought, flood, heat and other stresses, affect yields more than crop pests and diseases. We are trying to find a way to equip plants with the ability to tolerate environmental stress and maintain high yields, said Stephen Howell, a professor of genetics and cell biology. Plant cells produce proteins and ship them to different parts of the cell. Under normal conditions, these proteins are folded into their normal, healthy structures as they are produced. When a plant is under stress, its cells produce poorly folded or unfolded proteins. Then a built-in system senses this and "sets off an alarm in the cell," said Howell. In response to the alarm, another protein (IRE1) starts working and creates a different process which activates the stress response genes whose products bring about defensive measures that help the plant survive. "As it turns out, responses that are activated under stress conditions actually inhibit the growth of plants," said Howell. "This allows them to preserve their energy to survive the stress conditions." For plants in the wild, this response is a help for survival, he said. In production of agriculture crops, however, this response reduces yields. "You don't want crop plants to stop growing," Howell said. "You want them to continue to grow and produce even though they are under stress." With the new understanding of this stress response, the next step may be to silence the alarm system, said Howell. "What may be important is to disable some of these stress responses. That may make the plant more productive under stress conditions." How does Howell intend to make crop plants maintain high yields under stress conditions? | [

mmlu_train_42313 | Career education is instruction intended to help young people identify, choose, and prepare for a career. Such instruction may focus on a person's role in work, leisure, or family life. Career education differs from vocational education, which is designed to teach specific occupational skills. Career education includes the formal and informal learning that occurs in the family, in the community, and in schools. In schools, career education consists of instructive activities included in many courses. These activities are designed to improve the attitudes, knowledge, and skills important for work roles. Career education helps students develop self- understanding and use it to plan their education and working life. A complete career education program in school begins in kindergarten and continues at least through high school. Many colleges and universities also offer career education through their counseling programs. In kindergartens and elementary schools, youngsters learn about different types of work. In middle schools or junior high school, children begin to explore the occupations and leisure activities that interest them most. In high school, students get more specific information about occupations and life styles. They may be in classroom, small group, or individual sessions where they learn how to make career decisions. They also should obtain the skills they need for further study or for a job after graduation. Counselors provide information on such matters as how to locate and apply for jobs and how to be successful in interviews. Teachers and counselors use a variety of methods to provide career education, including films about occupations or industries. Children may invite parents or other adults to come to school and describe their jobs. A student may accompany a worker on the job. Cooperative education s classroom study with practical work experience. According to the passage, which statement is true? | [

mmlu_train_64362 | It's illegal for the police to attach a GPS unit to your car without your permission, as the U.S. Supreme Court settled in 2012.But if the police are in hot pursuit of a bank robber or other escaping criminals that threaten public safety, a GPS tracker is acceptable. But exactly how can the police GPS track a car that is moving fast? The answer to that question comes from StarChase,a new police technology being used by a small but growing number of law enforcement agencies.It allows the police to fire 4.5-inch glue-covered GPS bullet-like projectiles from an air gun fixed in their police cars.If the GPS tracker makes contact with the escaping robber's car, it'll stick no matter how fast the vehicle is going.That way, the police will have a constant read on the car's location and heading.Aside from simply apprehending criminals,it's believed this new technology could help save lives.If the police successfully fire a GPS unit at a speeding criminal,they can pull back from a high-risk chase.Chases can be incredibly dangerous to all involved,including innocent bystanders and other drivers.Once the GPS bullet connects,there's no need for the chase any longer. Now,predictably,a GPS-loaded gun isn't cheap. Police departments need to pay about $5.000 per vehicle for the technology,and individual GPS bullets cost as much as $250 each.That may sound expensive,but remember:The alternative is often thousands of dollars in property damage,and great human cost in injury and lost life.According to Star Chase,their GPS bullet system has an apprehension rate of 80%without any report of inury or property damage.If you'd like to learn more about the StarChase system,Popular Mechanics has just published a good article about it.There's also plenty more information available at the company's website.

mmlu_train_23564 | In the Arctic Ocean waters live the social animals---belugas, which is also known as white whales. Highly intelligent, these whales use different sounds to communicate and find their way. Belugas are also among the smallest kinds of whales. More than 210 belugas, including 31 in the United States, live in aquariums around the world. The Georgia Aquarium has asked for permission to bring 18 more belugas into the U.S. The whales were caught off the coast of Russia. The National Oceanic and Atmospheric Administration (NOAA) is considering the aquarium's request thoroughly. A law called the Marine Mammal Protection Act (MMPA) says the animals can only be brought into the country and put on display if they are caught without being hurt and there is an educational reason for doing so. Georgia Aquarium officials say the 18 belugas will help people learn more about the species and allow scientists to better understand how to protect it. The aquarium would also breed the whales so the U.S. aquariums can continue to display them. "When we can study and observe, we gain a better understanding of their biology and diseases that affect them, and learn how to aid populations in their natural habitats," says William Hurley, Georgia Aquarium's chief officer. "Much of this research would be impossible in the remote locations and extreme climates where the animals live." The Georgia Aquarium would own the 18 belugas and would rent some to aquariums across the country. Meanwhile, many scientists, including Lori Marino, a whale expert, feel strongly that the whales belong in the ocean, not in tanks. These scientists say the whales are being used for entertainment and not for education, and having them in aquariums is not necessary for the species to survive. Marino said, "Not only is it unfair to the belugas but there is no educational value in putting these whales on display." Many scientists are against the request because _ . | [

mmlu_train_57373 | People who are cheerful and relaxed are less likely to suffer from colds. It's possible that being full of vim and vigor helps the body fight illnesses, say the researchers from Carnegie Mellon University (CMU) in Pittsburgh. "We need to take more seriously the possibility that a positive emotional style is a major player in disease risk," says psychologist Sheldon Cohen, the study's lead researcher. In a previous study, Cohen and his colleagues found that people who tended to be cheerful and lively were least likely to develop sniffles, coughs, and other cold symptoms . Those findings were interesting, but they didn't prove that a person's attitude affects whether he or she gets sick. Instead, it was still probable that a person's underlying personality is what matters. Evidence suggests, for instance, that certain people are naturally more likely to be outgoing and optimistic, with high self-respect and a sense of control over life. This would mean that who we are, not how we feel, finally decides our chances of catching colds. To figure out which mattered more (personality or emotions), the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. They told the researchers about the positive and negative feelings they had experienced that day. The results showed that everyone in the study was equally likely to get infected. Their symptoms, however, differed depending on the types of emotions that they had reported over the previous 2 weeks. Among those who reported good moods and had been infected with the flu virus, for example, 28 percent developed coughs and stuffy noses. On the other hand, those symptoms struck 41 percent of people who had been less positive. Scientists argue about whether negative emotions or positive emotions have a stronger effect on how healthy we are. For now, it can't hurt to look on the bright side more often than not!

The spaceship Shenzhou VII blasted off on a Long March II-F carrier rocket from the Jiuquan Satellite Launch Center in the northwestern Gansu Province at 9:10pm.after a breathtaking countdown to another milestone on China's space journey. On board pilots Zhai Zhigang, Liu Boming and Jing Haipeng are expected to orbit the earth for three days, when one of them will float out of the cabin about 343 kilometers above the earth. When they make it, China will become the third country in the world who is able to conduct extravehicular activity (EVA) in space following the former Soviet Union and the United States. President Hu Jintao watched the historic moment at the launch center, joined by Chinese experts and other work staff. Hu briefly met the trio astronauts before they entered the spacecraft Thursday afternoon, wishing them "a complete success in this glorious and sacred mission". "During the mission, you will carry out China's EVA with homemade EVA space suit, which is a great leap for China's space technology." said Hu.

To really benefit from swimming, every swimmer should learn, as soon as possible, these four basic strokes; butterfly, backstroke, Breaststroke, and crawl. I feel that one of these-the breaststroke-is different from the others, since some young swimmers use this stroke naturally, without any training. In swimming there are certain rules every swimmer should follow: 1). Never swim alone! No matter how good you are in the water, don't risk drowning by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble. 2). Don't go beyond your abilities.

mmlu_train_59429 | Lakes, ponds, and beaches mean summer fun and cool relaxation from hot weather. But water also can be dangerous for kids if you don't take great care. Nearly 1,000 kids die each year by drowning. Here are some tips to keep your kids safe in the water: At the Lake or Pond *Don't let little kids swim alone without adult supervision-- lakes or ponds may be shallow near the bank and are suddenly deep sharply further out from shore. *Ponds and lakes may hide jagged rocks, broken glass, or rubbish. *Make sure kids wear foot protection; even in the water, they should wear socks or water shoes. *Watch out for weeds and grass in the water that could trap a leg or arm. *Most boating accidents, particularly among teenagers, are related to alcohol . Be sure teens know about the dangers of alcohol, on and off the water. At the Beach *Teach kids to always swim when and where a lifeguard is on duty. Unlike the calm waters of a swimming pool, the beach has special dangers like currents and tides . Check with the lifeguard when you arrive to find out about the water conditions. *Tell kids never to stand with their back to the water because a sudden wave can easily knock a child over. *Teach kids that if they're caught in a dangerous wave, they should swim parallel to the shore or should tread water and call for a lifeguard's help. Whether at the lake or at the beach, teach your child to get out of the water during bad weather, especially lightning. Swimming at a beach is more dangerous than in a pool because _ . | [

mmlu_train_61573 | We may all like to consider ourselves free spirits. But a study of the tracks left by 50,000 mobile phone users over three months has finally proved that the truth is otherwise. "We are all in one way or another boring," says Albert-Laszlo Barabasi at the Center for Complex Network Research at Northeastern University in Boston, who co-wrote the study. "Spontaneous individuals are largely absent from the population," Barabasi and colleagues used three months' worth of data from a mobile phone network to track the mobile phone towers each person's phone connected to each hour of the day, showing their general location. They conclude that regardless of whether a person typically remains close to home or wanders far and wide, their movements are probably predictable as much as 93 percent of the time. Surprisingly, the mobile phone data showed that individuals' movements were more or less as predictable at weekends as on weekdays, suggesting that routine is rooted in human nature rather than being an effect of work patterns. The mobile phone records were handled to make out the most visited locations for each user. Then the probability of finding a given user at his most visited locations at each hour through the day was calculated. People were to be found in their most visited location for any given hour 70 percent of the time. Not surprisingly, the figure increased at night, and decreased at lunchtime and in the early evening, when most people were returning home from work. The team analyzed the randomness of people's traces to show it was possible in theory to predict the average person's places as much as 93 percent of the time. "Say your routine movement is from home to the coffee shop to work: if you are at home and then go to the coffee shop it's easy for me to predict that you are going to work," says co-author Nicholas Blumm. This predictability was not much affected by differences in age, gender, language spoken or whether a person lived in a rural or urban setting. A phone user's location is shown by _ . | [

mmlu_train_38643 | Laughter Yoga is a unique technique invented by Dr Kataria, a doctor from India, by which you can learn to "Laugh for No Reason". You don't even need a sense of humor, no funny jokes or comedy programs -- just a willingness to laugh -- and in the present climate everyone needs to laugh more. Laughter Yoga is a combination of Laughter Exercises and Yogic Breathing, so that you increase the amount of oxygen in your body while being playful, resulting in you feeling healthier, energetic and alive. This actually changes the physical conditions of your body so that you start to feel happier. Laughter Yoga is generally done in groups although it can be practiced alone. When you make eye contact with someone and you're both willing to laugh, the laughter is increased. However, we do say that you can "Fake it, fake it till you make it" because the body doesn't know the difference between fake and true laughter; as long as you're willing to laugh you'll experience the same health benefits. Laughter Yoga started in a park in Mumbai in 1995 with just 5 participants, and now there're over 6,000 laughter clubs in 60 different countries -- showing the willingness of the world to laugh together. In the UK, Julie was one of the first people to train as a Laughter Leader with Dr Kataria in June 2002. In 2006 she was awarded Laughter Ambassador for her selfless service to promote Laughter Yoga. "Yoga has been part of my life for 30 years but 7 years ago my life changed when I discovered Laughter Yoga. I believe laughter and yoga are both good for your health," says Julie.

mmlu_train_5754 | "Humans should not try to avoid stress any more just as they would not _ food, love or exercise," said Dr. Hans Selye, the first physician to record the effects of stress on the body. While here's one question that continuous stress is harmful, several studies suggest that challenging unexpected and difficult situations can be good for you. In a 2001 study of 158 hospital nurses, those who faced considerable work demands but dealt with the challenge were more likely to say they were in good health. In a study at theprefix = st1 /AcademicCenter, researchers put volunteers through a stressful experience: a timed task that required memorizing a list followed by a short test. Those who did well on the memory test had an increase in levels of immunoglobulin A, which is the body's first line of defense against germs . Stress makes the body produce certain stress hormones. In short bursts these hormones have a positive effect including improved memory function. "They can help nerve cells deal with information and put it into storage," says Dr. Bruce McEwen of Rockefeller University inNew York. But in the long run these hormones can have a harmful effect on the body and brain. "Continued stress is not good for you," says Dr. Bruce," it's the short burst of stress that could be protective." We can conclude from the study of the 158 nurses in 2001 that_. | [

Then do you watch the popular program?"A Bite of China " is a documentary on Chinese delicious food which has been broadcasted by Chinese central television. Is there any holiday that isn't celebrated with a special festival food? Here are several traditional Chinese foods: Eggs hold a special meaning in many cultures, and China is no exception . The Chinese believe eggs mean producing something new. After a baby is born, parents may hold a "red egg and ginger party," where they pass out eggs to announce the birth. In some areas of China the number of eggs represents the sex of the child, for example, an even number(1,3,5,---) for a girl, and an odd number(2,4,6---) if a boy has been born. Noodles are a symbol of longlife in Chinese culture. They are as much a part of a Chinese birthday celebration as a birthday cake with lit candles is in many countries. Since noodles represent long life, it is considered very unlucky to cut it off. Although westerners sometimes may be very sorry to see fish lying on a plate, in China a whole fish is a symbol of richness. In fact, at a party it is traditional to serve the whole fish last, pointed toward the valued guest. Fish also has a special meaning because the Chinese word for fish, yu, sounds like the word for richness or plenty, and it is believed that eating fish will help your wishes come true in the year to come. A very popular dish during the Dragon Boat Festival is Zongzi. This tasty dish is made of rice dumplings with meat, peanut or other delicious food in bamboo leaves. The tradition of Zongzi is meant to remind us of a great man, Qu Yuan.

mmlu_train_20100 | About five years ago, an American electrical engineer named Scott Brusaw and his wife Julie came up with the idea of putting solar panels on the ground rather than the roof. Then they began to develop the Solar Roadway. The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun while providing safer driving conditions, along with power and data delivery. They predict that the Solar Roadway will pay for itself through the generation of electricity along with other forms of income and that the same money that is being used to build and resurface current roads can be used to build the Solar Roadways. Each Solar Road Panel measures roughly 4 meters by 4 meters and contains a microprocessor that monitors and controls the panel, while communicating with neighboring panels and the vehicles traveling overhead. The inventors suggest that this provides a communications device every 4 meters on every road which could be used for example to warn drivers of cars which are moving across a centre line and various other speed control problems. The top of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions _ need. According to the inventors, the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop, or at any business that has paved Solar Road Panels in their parking lots. The inventors say their Solar Roadway has many functions and advantages from main roads to driveways, parking lots, bike paths, sidewalks and runways. The Federal Highway Administration has given Brusaw $100,000 to develop the invention and Brusaw hopes to build a smart-road parking lot in the coming spring .

mmlu_train_18756 | In March 2004, Joe Ryan got a collection notice from a billing agency for Littleton Adventist Hospital near prefix = st1 /Denver,Colorado. The hospital wanted payment for surgery totaling $41,188. Ryan had never set foot in that hospital. Obviously there was some mistake. "I thought it was a joke," says Ryan. But when he called the billing agency, nobody laughed. Someone named Joe Ryan, using Ryan's Social Security number, had indeed been admitted for surgery. He figured clearing this up would take just a few phone calls. Two years later, Ryan continues to suffer from the damage to his credit rating and still doesn't know if his medical record has been cleared of wrong information. Joe Ryan was the victim of a little-known but frightening type of consumer fraud that is on the rise: medical identity theft, which involves using your name to get drugs, expensive medical treatment and even cheating insurance payments. As Ryan discovered, money isn't the half of it. When someone steals your name to receive health care, his medical history becomes part of your record -- and setting the record straight can be extremely difficult. That's because, in part, the information is distributed among dozens of caregivers, from doctors to medicine stores to insurance companies and labs. "I wanted to help straighten this out," says Ryan, "so I went to the hospital, and they had a three-inch-thick record for me, but they wouldn't let me see it. I showed them my ID, and they said that's not Joe Ryan's signature. Well, of course not! They had this other guy's signature." Ryan had fallen into a victim's Catch-22: If your record doesn't appear to be yours, you may not have the right to see it, much less change it. Ryan's next step was a visit to the Police Department. But the cops concluded there was not much they could do; local law enforcement has little experience with medical ID theft, and cases can end up being considered a civil matter. An even worse consequence of medical ID theft is _ . | [

mmlu_train_44179 | The forest in Senegal, a country in western Africa, is full of the chimps' usual noises. Suddenly dogs bark. Larger male chimps drop from the trees to face the threat while the others climb to safety. Then the dogs' young human masters appear. One mother chimp with a tiny baby tries to run. The dogs attack and separate them. The two teenage boys quickly catch the baby chimp. But they don't act out of sympathy --- they save the baby so they can sell it. After the teenagers return to their hometown, they visit a man who is said to be very interested in chimps. When they ask the man, Johnny Kante, if he wants to buy the baby, he replies, "That's not what we do." Kante is a member of a scientific team. Although Kante is angry with the teens for capturing the chimp, he hides his anger and persuades them to take him to the baby chimp. Unsure of what to do next upon seeing the chimp, Kante calls Jill Pruetz, the head of the chimp research team. "I'm really worried," says Pruetz, doubtful that the mother is still alive. But knowing that wild chimps sometimes adopt orphans , Kante and pruetz decide they must try to return the baby chimp to its wild community. Kante pays another visit to the teenagers. After he explains how much trouble they are in, because chimps are an endangered species, he requests they should give him the frightened baby without payment. They agree. Kante takes the baby chimp to his home and feeds her milk from a bottle whenever she cries. The next morning, Pruetz and Kante leave the baby with another team member and begin their search for the wild chimps. Pruetz quickly finds the group in the woods. She recognizes the female that is without her child. Pruetz is so excited that she runs the entire mile back to bring the baby chimp to the tree where the chimps are hanging out. The researchers place the baby on the ground near the tree and back away. Almost immediately, a male chimp drops to the ground and stares at the baby curiously. He carries her back to where the mother is waiting. Pruetz still can't believe how fortunate they were to have reunited the mother and child. "Surprising is the only word I can think of," she says. It can be learned from the passage that _ . | [

Smartphones were the source of 65 % of its Internet traffic and 41 % of its e-commerce, according to a report by the analyst Mary Meeker, titled "Internet Trends 2015". India's Internet boom has started. Within three or four years, almost every adult in India will own a smartphone. They will be used to order goods, read news, monitor crop growth and so on. Indian adults will be very interested in these devices just as young Americans are. 87% of Americans between the ages of 18 and 34 who own smartphones say they never separate from these: "My smartphone never leaves my side." Four out of five say that the first thing they do on waking is to reach for their smartphones. And three fifths believe that in the next five years everything will be done on mobile devices. In the business world, the rise of mobile platforms is dramatically transforming many industries all over the world. What Indian software developers have to do is to start thinking about solutions to old problems by using all the features of these new devices. They need to take advantage of the unique properties of smartphones and tablets. As Indian software developers and enterprises master the smartphone, they will be able to export their solutions to the rest of the world. This will make possible a new tech revolution that is greater than what created India's IT industry in the 1980s and 1990s.

mmlu_train_62934 | The time children spend outdoors could be linked to a reduced risk of being short-sighted, research suggests. An analysis of eight previous studies by University of Cambridge researchers found that for each additional hour spent outside per week, the risk of short-sightedness was reduced by 2%.They said exposure to natural light and time spent looking at distant objects could be key factors . The studies involved more than 10,000 children and adolescents. Dr Justin Sherwin and his research team concluded that short-sighted children spent an average of 3.7 fewer hours per week outdoors than those who either had normal vision or were far-sighted. But they said the reasons were not yet clear.They expected to find that children who spent more time outdoors also spent less time doing activities like reading, studying or playing computer games, but no such link was found in two of the eight studies which looked at this relationship. However, Dr Sherwin said they would now need more precise data to try to understand which factors, such as increased use of distance vision, reduced use of near vision, natural ultraviolet light exposure and physical activity,are most important. "Any increase in time spent outdoors must be weighed against exposure to ultraviolet radiation and the increased risk of skin cancer, cataracts and other cancers."he said."On the other hand, increasing outdoor physical activity could protect against diabetes and obesity, for example." Short-sightedness is a common eye condition that causes distant objects to appear blurred , while close objects can be seen clearly. It is much more common today in the UK and the United States than it was just 30 to 40 years ago. Approximately 1-2% of five-year-olds to seven-year-olds in the UK have short-sightedness.About.five million British people are short-sighted and some 200,000 of them will be seriously short-sighted.
