mmlu_train_65479 | Parents whose children think the latest Nike or Adidas shoes may be better than buying old-fashioned plimsolls because they encourage a healthier style of running, researchers said. Big companies, like Nike and Adidas, make millions of dollars from selling highly-cushioned shoes both as fashion and sports shoes. The researchers warn that wearing such shoes from an early age can make it difficult to run in a healthy way. Once we have grown used to running in this kind of shoes, it is very difficult to change our technique, even if we remove our shoes, it can raise the risk of injury. Children should be encouraged to wear shoes with thin soles such as plimsolls from a young age to help them develop a natural "barefoot" running style, experts said. Dr Mick Wilknson, who did the research, told the British Science Festival in Newcastle, "If I would advise someone on what to give their child, I would say don't go and buy them expensive Adidas or Nike, just get them a pair of flexible, flat shoes. Give them basic foot-ware, nothing fancy, nothing particularly cushioned." Running in flat shoes, barefoot, encourages the runner to use the front of their foot which is a better technique for running, especially long distances as the human was designed to do. Around the world, and in particular in the US, running barefoot is becoming more and more popular with many long distance runners training without shoes. Dr Mick Wilknson believes that training and running barefoot or in flat running shoes can help reduce injuries to runners, he said: "Injury rates in running have not changed since the 1970s, despite claims of improvements in running shoes. That has led some to conclude that barefoot running is better." What can we infer according to Dr Mick Wilknson? | [

mmlu_train_63804 | According to the Ministry of Health, 260 million Chinese people have chronic diseases, and 85 percent of all deaths in China are caused by such diseases. Among them, cardiovascular disease has bothered more people than any other kind of chronic disease. According to the WHO(World Health Organization), salt consumption , one of the key causes of high blood pressure that can lead to cardiovascular disease, is much higher in China than in other countries. Douglas Bettcher, the director of the WHO's Tobacco Free Initiative, says, "The average Chinese person consumes about 12 to 14 grams (of salt) per day, while the suggestion of the WHO is consumption of less than 5 grams per day. High salt consumption is a major cause of cardiovascular disease and high pressure in China. Changing the way that food is prepared could reduce salt consumption in China. Another major risk factor in China is smoking. Dr Michael O'Leary, a representative of the WHO, says, "We know already that one million deaths in China are related to smoking, This is an enormous number. It means that we are seeing nearly 3000 deaths a day in China, or two deaths every minute, related to smoking. According to O'Leary, about 26 percent of men who die from smoking-related diseases in China die before the age of 60. People who can still contribute a great deal, in other words, are dying too young. China has tried to ban smoking , but more efforts are needed. More than half of chronic diseases are preventable by changing lifestyles and reducing risks. The four key risk factors are: smoking, diets high in fats, salt and sugar, environments that prevent physical activities, and alcohol consumption. These are the areas on which efforts to make changes need to concentrate. According to the WHO, how much salt should a Chinese person consume? | [

mmlu_train_53679 | A Chinese space capsule carrying three crew members has returned to Earth following a 13-day mission . Images of the capsule landing in Inner Mongolia at 10:05 local time were shown live on television. The astronauts, including China's first woman in space, carried out a successful manual docking with the Tiangong-1 laboratory module. This is a key step towards China's goal of building a space station by 2020. Premier Wen Jiabao praised it as a "complete success". "This is another outstanding contribution by the Chinese people to humanity's efforts to explore and use space," Mr Wen said in Beijing. "It feels so good to stand on Earth, and it feels even better to be home," astronaut Liu Wang was quoted by national broadcaster CCTV as saying. "Tiangong-1, our home in space, was comfortable and pleasant. We're very proud of our nation, " female astronaut Liu Yang said. The crew of the Shenzhou-9 craft successfully carried out the country's manual docking operation earlier in the week. The delicate procedure, which involved bringing together two orbiting objects travelling at thousands of miles an hour, was mastered by USSR and US space teams in the 1960s. The crew also carried out automatic docking of the two crafts in the process. The three astronauts returned to the Shenzhou-9 spacecraft on Thursday and performed a manual separation from the space laboratory. They touched down in Inner Mongolia's Siziwang county on Friday, with the capsule equipped with a parachute to slow its approach. Ms Liu, 33, is a major in China's air force from the central province of Henan. On China's Tencent QQ messaging service, she goes by the name "little Flying knight".

So in the future you won't have to remember a number when you want to use a machine or take money out of a bank. You'll just have to look at the machine and it will be able to tell who you are. The eye-recognition programme is tested in shops and banks in the USA, Britain and Italy. Scientists are working on other systems, such as knowing you from the shape of your face or hand or even your smell! And machines can already tell who you are from your voice or your fingerprint . But eye-recognition will replace other ways of finding out who you are. It is better, because your eyes don't change as you get older, or get dirty like hands or fingers.

mmlu_train_15663 | Bad teeth can be painful and even be deadly. Infections of the gums and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12yearold boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed. Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water. When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel , the hard surface on teeth, to help prevent holes from forming. But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used. Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could _ the correct development of permanent teeth. Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear--usually at around six months. What is the purpose of the author in writing the passage? | [

mmlu_train_6577 | Walking is the exercise of choice for most dieters. You don't need a gym membership to do this effective exercise. Here's how to prepare: The only equipment you really need is a decent pair of walking shoes. What matters most is comfort. When you're shopping for shoes: *Wear the socks you plan to exercise in. That way you'll get the best fit. *Try on both shoes. Most people's feet aren't exactly the same size. Choose a pair that fits your larger foot. *Allow a little extra room. Feet swell when you walk, so buy a pair with about a thumb's width between your longest toe and the toe of the shoe. Sure, walking comes naturally. But the following tips will help you stay comfortable and get the most out of your walk: *Look ahead. Keep your neck straight and your head held high. If you have to look down to see where you're going, lower your eyes, not your head. *Move both arms. Let your arms swing naturally at your sides, and you'll burn up to 15 percent more calories by keeping your arms moving. *Don't carry unnecessary weight. Some people try to get in extra exercise by carrying a couple of light dumbbells , but fitness-walking experts say that's risky: The weights can pull you off balance and tighten muscles in your back or legs. Walking is one of the safest activities. Still, the following tips may be helpful: *If you're walking at night, wear a piece of reflective clothing. *If the path is dimly lit, bring a good flashlight. *When the weather's hot, be sure to drink some water before you set out and better take a bottle of water with you if you plan to walk quite a long time. *If your path is rough, protect your ankles. Consider wearing a comfortable bandage for support. According to the text, which of the following is correct? | [

mmlu_train_88091 | One of the most famous scientists to study adaptations was Charles Darwin . He was born in England in 1809. He wasn't the best student in his school, but when he was 16, his father sent him to a medical school. Charles liked spending time outdoors observing nature more than having medical classes. He dropped out without graduating. Next, Charles' father sent him to school to become a minister . This time he made it to graduation, but he didn't want to do the work of a minister. His friends encouraged him to follow his interest in science. Luckily, Charles was invited to sail on the Beagle as an unpaid scientist after graduation. The Beagle was to travel to South America and then around the world. Their task was to make maps of the places they visited. On December 27th, 1831. Charles Darwin sailed from England on the Beagle. The trip was planned to last two years. In fact, it lasted five. During this time, he saw many amazing things. He collected lots of plants and animals and took them back to England to begin his scientific study. Twenty-three years later, Darwin published a scientific paper with another man named Wallace. Darwin described how some animals have adaptations that help them survive. _ are passed on to offspring . Darwin's ideas about adaptations are still very important to the study of living things.

mmlu_train_64320 | New research is strengthening evidence that eating vegetables may be some of the best health advice. A study of 500, 000 Americans has found that just one extra serving of fruit or vegetables a day may reduce the risk of developing head and neck cancer. Many studies have shown that diet plays a role in cancer. Cancer experts now believe that up to two-thirds of all cancers come from lifestyle such as smoking, diet and lack of exercise. Tobacco and alcohol use increases the risk of head and neck cancer, which affects the mouth, nose, sinuses and throat. Researchers at the National Cancer Institute asked men and women aged 50 and older about their diets, then followed them for five years to record all diagnoses of head and neck cancer, the sixth-leading cause of cancer-related death worldwide. The study found eating six servings of fruit and vegetables per day per 1, 000 calories cut the risk of head and neck cancer by 29 percent compared to eating one and a half servings. An adult needs around 2, 000 calories a day. "One more serving of fruit or vegetables per 1, 000 calories per day reduced head and neck cancer risk by 6 percent,"said Neal Freedman, a cancer prevention fellow at the NCI. A second study in 183, 000 people of California and Hawaii found a diet high in flavonols might help reduce pancreatic cancer risk, especially in smokers.

mmlu_train_10541 | You stare at waterfall for a minute or two, and then shift your gaze to its surroundings. What you now see appears to drift upward. These optical illusions occur because the brain is constantly matching its model of reality to signals from the body's sensors and interpreting what must be happening--that your brain must have moved, not the other; that downward motions is now normal, so a change from it must now be perceived as upward motion. The sensors that make this magic are of two kinds. Each eye contains about 120 million rods , which provide somewhat blurry black and white vision. These are the windows of night vision; once adapted to the dark, they can detect a candle burning ten miles away. Color vision in each eye comes from six to seven million structures called cones . Under ideal conditions, every cone can "see" the entire rainbow spectrum of visible color1s, but one type of cone is most sensitive to red, another to green, a third to blue. Rods and cones send their messages pulsing an average 20 to 25 times per second along the optic nerve. We see an image for a fraction of a second longer than it actually appears. In movies, reels of still photographs are projected onto screens at 24 frames per second, tricking our eyes into seeing a continuous moving picture. Like apparent motion, color1 vision is also subject to unusual effects. When day gives way to night, twilight brings what the poet T.S. Eliot called "the violet hour." A light levels fall, the rods become progressively less responsive. Rods are most sensitive to the shorter wavelengths of blue and green, and they impart a strange vividness to the garden's blue flowers. However, look at a white shirt during the reddish light of sunset, and you'll still see it in its "true" color1--white, not red. Our eyes are constantly comparing an object against its surroundings. They therefore observe the effect of a shift in the color1 of illuminating on both, and adjust accordingly. The eyes can distinguish several million graduations of light and shade of color1. Each waking second they flash tens of millions of pieces of information to the brain, which weaves them incessantly into a picture of the world around us. Yet all this is done at the back of each eye by a fabric of sensors, called the retina , about as wide and as thick as a postage stamp. As the Renaissance inventor and artist Leonardo da Vinci wrote in wonder, "Who would believe that so small a space could contain the images of all the universe?" The visual sensor that is capable of distinguishing shades of color1 is called _ . | [

mmlu_train_37429 | If you are afraid of the dark,it's not a big deal.It's perfectly normal to feel afraid After all,animals do too. "Fear matters,"says Karen Warkentin,an ecologist."It's a good thing," she adds, "because fear makes you do things that keep you alive." Like kids,many animals experience fear and they respond to the feeling in variety of ways.A frightened turtle pulls its head and legs inside its shell.A small fish will swim away when a big,hungry fish approaches. Some animals respond to fear in ways you might not expect.The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red--eyed tree frogs in Costa Rica. In this species,female frogs attach jellylike clumps of their eggs to the undersides of leaves.The leaves hang on branches that dangle over ponds.After they hatch from the eggs,the tadpoles then fall into the water,where they eventually grow into adult frogs. Tree frog eggs usually grow for 6 days before hatching.If they sense that a hungry snake is about to attack,however,they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim,by falling into the water early,the tadpoles can escape. If hatching early helps protect red--eyed tree frogs from snakes,you might wonder why their eggs don't always hatch sooner.It turns out that hatching early brings its own danger.Once tadpoles land in the water,hungry fish and other animals like to eat them too.Staying in their eggs for a full 6 days,then,allows frog embryos to grow big and strong.This extra growth improves their chances of surviving in the water. We are told in the passage that tree frogs _ . | [

mmlu_train_9089 | Joseph Francis Charles Rock (1884-1962) was an Austrian-American explorer, botanist, and anthropologist . For more than 25 years, he travelled extensively through Tibet and Yunnan, Gansu, and Sichuan provinces in China before finally leaving in 1949. In 1924, Harvard sent Joseph Francis Rock on a treasure hunt through China's southwestern provinces--the Wild West of their day. But gold and silver weren't his task: Rock, a distinguished botanist, sought only to fill his bags with all the seeds, saplings, and shrubs he could find. During his three-year expedition, he collected 20,000 specimens for the Arnold Arboretum . Botany, though, was just one of Rock's strengths. As an ethnologist , he took hundreds of photographs of the Naxi, a tribe in Yunnan province, recording their now-lost way of life for both Harvard and National Geographic, and took notes for an eventual 500-page dictionary of their language. His hand-drawn map of his travels through China's "Cho-Ni" territory, in the Harvard Map Collection, includes more than a thousand rivers, towns, and mountains indicated in both English and Chinese, and was so well made that the U.S. government used it to plan aerial missions in World War II. Scientist, linguist, cartographer, photographer, writer--Rock was not a wallflower in any sense. Arrogant and self-possessed, he would walk into a village or warlord's place "as if he owned the place," said Lisa Pearson, the Arboretum's head librarian. In declaring his successful return under the headline "Seeking Strange Flowers, in the Far Reaches of the World," the Boston Evening Transcript ran a large photo of the daring explorer wearing in a woolly coat and fox-skin hat. "In discussing his heroism including hair-raising escapes from death either from mountain slides, snow slides and robber armies, he waves the idea away as if it is of no importance."

On Friday, three men came into the hotel and asked for rooms. Mr. Knight said there were no rooms ready because of the meeting. The men were unhappy. Mr. Knight wanted to help them. He remembered that Room 418, a small room, was empty. He asked them if they could share a room. The three men said they would. Mr. Knight said the room would be thirty dollars; ten dollars for each person. Each man gave him the money and then went up to the room. Mr. Knight soon began to feel sorry. "Thirty dollars is a lot to ask as a price for that small room." he thought. He called his assistant over and said, "Here is five dollars. Take it to the men in Room 418. I asked too much for their room." The assistant took the money. While he was on the way there, he started to think, "How can three men divide five dollars? I'll give them each only one dollar and keep the two dollars for myself. The men will be happy to get something back. And Mr. Knight will never know." So the assistant returned one dollar to each man. Each man had at first paid ten dollars. After the assistant returned them one dollar each, each had actually(in fact) paid nine.

It's hard to see an Arctic bear in snow. Its white fur helps protect it. Chameleons can hide by changing colors. Their skin turns the same color as what is around them. Some chameleons can change colors in five minutes. Many animals try to look bigger than they are to stay alive. Some animals can make other animals think they are very big. If they look very big, animals that are looking for food will run away. Bears can walk on two legs. They look very, very scary. Some animals will run away from them. Many animals try to stay around other animals. This helps them stay alive. Zebras stay close together so that they can help each other look out of danger.

mmlu_train_54130 | If you're looking for a fairly painless way to lose weight, researchers at Brigham Young University have a new solution for you: Put yourself on a regular sleep schedule. People who keep a regular sleep routine have a lower body fat than those who keep irregular sleep hours, says a new study. Led by Bruce Bailey, professor of exercise science, researchers followed 300 female college students aged 19 to 26, who were given activity trackers to watch their movements and activities, including waking and sleeping times . Researchers also measured their body composition before and after the one-week study period. What the researchers found: Body fat varied with sleep quantity. Women who slept between 8 and 8.5 hours a night had the lowest body fat. While those who slept less than 7 hours or over 9 hours had higher body fat. High quality sleep was associated with lower body fat while poor sleep was connected with higher body fat. Waking and going to sleep at the same time every day was most strongly linked with lower body fat. The difference in body weight was greater with more variation in sleep pattern. Women whose sleep patterns varied by 90 minutes a night had higher body fat than those whose sleep patterns varied by 60 minutes or less on average. The study followed up on a body of research conducted over the last few years that ties quality and quantity of sleep to weight loss and better weight control. While researchers don't know exactly how sleep schedules affect body weight and fat, other studies have shown that sleep has an effect on physical activity, appetite , and the hormones that control metabolism , and the signals that tell us we're full. Which of the following about the study led by Bruce Bailey is true? | [

More than 15 percent of the Chinese youth have been found with mental problems,and about 30 million young people under 17 are suffering from depression,the Shanghai-based Wenhui Daily reported. The World Health Organization estimated that before 2020,the rate of children with mental problems will increase to 50 percent,and mental problems will become a major factor behind death and illness in the young worldwide. Deng Xiaohong,the spokesperson for the Beijing Municipal Health Bureau,said rapid social change is one of the reasons behind the rising number of youngsters with psychological problems. If these mental diseases are not _ on time,occurrence of crime,drugtaking and other dangerous behavior are expected to rise. Experts said mental disease could be caused by many factors,such as the inability to handle interpersonal relations well,unstable emotions and pressure from the overload of study. A number of experts have also said the one-child policy is another reason leading to poor mental health in the young. Children were said to be too "spoiled" and "selfish" in one-child families. Schools in many cities were reported to roll out measures to help students maintain their mental well-being. Yin Jingmiao,a teacher of the Beijing No. 105 Middle School,told China Daily that the school invites psychologists to provide counseling to students three times a month. "Students can be arranged to have 40-minute counseling sessions," Yin said.

mmlu_train_44391 | A warm blanket is the ideal sleep aid for a freezing winter night. The right blanket can warm your bones but the wrong one can affect your sleep. I asked experts for advice on picking the perfect blanket for a good night's sleep. Here's what they told me. When it comes to sleep temperature, experts recommend following the principle: not too cold, not too hot, but just right. "People seem to sleep best at temperature between 62 and 70 degrees F," says Dr. Alice Hoagland. When the surrounding temperature falls too low, it can _ you from sleep. A good blanket helps drive the coldness away. At the other extreme, overheating yourself can affect your sleep as well. "Core body temperature typically drops during the first four hour's of sleep," says Dr. Hoagland. This decline in body temperature helps you fall asleep and stay asleep. "In medical care, weighted blankets are one of our most powerful tools for helping people who are anxious, upset, and possibly losing control," says Dr. Karen Moore. These special blankets are filled with weighted pellets. Weighted blankets are also marketed for general use as an aid to sleep and relaxation. Like a firm hug, weighted blankets help us feel safe." This is the reason why many people like to sleep under a blanket even in summer. "If you want to try this type of blanket, the best weight depends on your body size and personal preference. However, 15 to 30 pounds is typical for adults," Moor says. She adds that weighted blankets are not recommended for those recovering from surgery. "People can also have serious preferences for a particular blanket," says Dr. Hoagland. "Regularly using a favorite blanket for sleep can help to develop a conditioned response so that sleep is quicker." In fact, many sleep centers ask patients to bring their own blanket and pillow from home, which helps them fall asleep more easily. What do we know from the passage? | [

Scientists could not control the problem. The bees spread. They went from Brazil to Venezuela. Then they went to Central America. Now they are in North America. They travel about 390 miles a year. Each group of bees, or colony , grows four times a year. This means one million new colonies every five years. Why are people afraid of killer bees? People are afraid for two reasons.

mmlu_train_56324 | None of our early ancestors could digest milk as adults because their bodies never had to -milk drinking simply wasn't an option.As people began to extract milk from animals, though, some people developed the ability to keep drinking it throughout their lives. Scientists mow know of a milk-related mutation in our genes--the chemical instructions for life that we carry in almost every cell in our bodies.People who have a mutated form of one particular gene can drink milk just fine.People without the mutation tend to get sick from milk. To figure out where, and possibly why, milk drinking started, some scientists have been looking at who has the milk-digesting mutation to day Pattems are striking. Most adults in Northern and Central Europe are able to digest milk--and they do.Cheese, butter and other dairy products are popular in countries such as Sweden, Denmark, Germany and England.Because European settlers dominated North America, most people here can handle milk just fine, as well.That may explain why ice cream is such a popular dessert in the United States. In much of Africa, Asia and South America, on the other hand, people tend to avoid dairy products because they lead to diarrhea and other stomach problems.(That's why you won't typically find cheese on the menu at a Chinese, Japanese or Ethiopian restaurant.) Native Americans are also unable to digest milk. Based on these genetic patterns, scientists have long thought that milk drinking started in Northern Europe, where dairy is an institution and the milk-digesting mutation is everywhere. A recent study painted a different picture.With a computer model, Thomas and colleagues looked at the spread of the milk-drinking mutation, farming and other related factors.Working backward, the scientists concluded that the first milk-drinkers lived in Central Europe around what's now Hungary about 7500 years ago.The practice didn't start farther north, as scientists had thought before.

mmlu_train_36218 | About 1 in 15 households drink bottled water today, spending about $ 4 billion a year on it. Although the reasons for the trend are many, bottled water's health benefits fall near the top of the list. Surveys have found that about 25 percent of bottled water drinkers choose the beverage for health and safety reasons; another quarter believe it is pure and free of contaminants . Regardless of its pristine image, bottled water is not necessarily any purer or more healthful than what flows right out of the tap. Consider that the Food and Drug Administration (FDA), the bottled water industry watchdog, does not require that bottled water meet higher standards for quality, such as the maximum level of contaminants, than public water supplies regulated by the EPA. For the most part, the FDA simply follows EPA's regulatory lead. Granted, bottled water is often filtered to remove chemicals such as chlorine that may impart a certain taste. But that doesn't make it any safer. In fact, about 25 to 40 percent of bottled water comes from the same municipal water supplies as tap water. Furthermore, some bottled waters do not contain any or enough of the fluoride needed to fight cavities. The only way to determine whether a certain water contains the mineral is to check with the company that bottles it. This is not to say that bottled water is necessarily any better or worse, from a health standpoint, than tap water. It's certainly preferable to tap water for those who like its taste. The problem is that many consumers pay 300 to 1,200 times more per gallon for bottled water than for tap water because they think bottled water is the more healthful of the two. Bottlers add to the confusion by sprinkling terms such as "pure", "crystal pure" and "premium" on labels illustrated with pictures of glaciers, mountain streams, and waterfalls, even when the water inside comes from a public reservoir. However, the FDA has set forth regulations requiring clear labeling of bottled waters. The mini glossary of bottled waters explains what some of the terms used on bottles really mean.

It's an interesting and exciting new improvement in today's world as we look for better ways to protect the quality of the air we breathe and conserve our natural resources. The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which are used to power a car's engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution. A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144 volt battery pack is actually recharged( ) through the energy that is produced when the car's brakes are used. This is referred to as "regenerative braking", because it generates electricity. Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically ( ; )shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up. Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, "I am low on gas". When it completely runs out, the warning reads, "YOU ARE NOW OUT OF GAS!" Then the electric power supply kicks in to let the driver travel a few more miles to a gas station. Regenerative braking is an important process of the hybrid car because _ . | [

mmlu_train_11048 | China's famous scientist, the Cloth Shoes Academician Li Xiaowen passed away on January 10th, 2015 in Beijing at the age of 67. Hundreds of thousands of citizens sang high praise for him online, showing their respect to the leading authority in remote sensing field. Following Li Xiaowen's last wish, his family held a simple funeral for him, while many admirers from all over the country came to the funeral for remembrance. Some national leaders including Premier Li Keqiang also sent a wreath. Li was a professor at Beijing Normal University and an academician of the Chinese Academy of Sciences. His research achievements have advanced the development of remote sensing science, and made China one of the leaders in this field. He also received several famous science prizes from China. He published 1,878 essays on his blog since 2007. All his students have thumbed up to Li for his contributions to the development of remote sensing. He was known to everyone in the remote sensing circle, but was impressive on citizens for a photo. In recent years, Professor Li's quiet and self-effacing behavior was recognized through social media. In 2014, a photograph of Academician Li was taken by his student, in which he was attentively making a lecture with shabby clothes, grizzled hair and straggling beard, without socks, and wearing black cloth shoes. He looked like an old villager, rather than a famous scientist. The photo became popular on the Internet and earned him the title of the "Cloth Shoes Academician." His simple plain image, kindness to all his students and dedication to his career are three important features on him. All these are precious to educational and academic community. "The society is changeable but Academician Li is quiet. He faced all stuff with his characters of quietness and simplicity. It is clear that he has become the 'Teacher Immortal'." said Ge Yuejing, a senior leader of Beijing Normal University. Which statement is TRUE according to the passage? | [

mmlu_train_69419 | In today's world of modern science and medicine, a more traditional treatment is once again becoming popular-animal friendship. It is now well-known that people with problems such as heart disease or cancer live longer and get better more quickly if they have pets. Keeping pets lowers blood pressure and makes people less worried. Animals are increasingly important in treating older people who have memory loss and other brain problems. These people often feel nervous and upset. Activities with animals help them improve their physical condition and also give them joy, entertainment and loving friendship. Here is a case that shows the benefits of animals. John was a six-year-old _ . He had no physical problems. He just refused to talk. His older cousin, Ned, had a parrot called Sally, and John used to visit it. When he arrived, Net used to say, "Hi, John!" We all know parrots copy what they hear. After a few visits, Sally began saying "Hi, John!" when John came into the room. Then, one day, John turned to the parrot and replied "Hi, Sally!" Staying with the parrot encouraged John to begin talking. Another use of animal helpers is in schools. In some cases, animals are used to help children with physical or personal problems. In other cases, they are used to teach children to get on and share with others, and even to teach them about animals. If you want to know more about animal helper programs, you can get in touch with organizations like Riding for the Disabled or do a search under "animal therapy" on the Internet.

mmlu_train_38895 | Scientists warn today that the Atlantic bluefin tuna faces disappearance unless certain action is taken. They used electronic ways to track the movement of the powerful fish from the Gulf of Mexico to the Mediterranean, and report today in the journal Nature that meals of sushi and sandwiches with tuna worldwide are more dangerous than anyone has imagined. The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A good one can fetch as much as PS 52,000 in the Tokyo fish markets. "In my lifetime, we've brought this big fish to the doorstep of death in the western Atlantic Ocean," said Barbara Block of Stanford University in California. "The electronic way of tracks provides the best scientific information we've ever had to manage these tuna and we must, as an international community, start to act actively to make sure of the future of this fish. " Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore in search of deep ocean fish. Tuna--in the Mediterranean and Japan--have been under increasing pressure for years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since 1969.There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger, eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000 in the east, no one knew whether the limits worked. So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water temperatures. "There are two ways to save the Atlantic bluefin tuna--protect them in their production grounds and in their feeding grounds," Prof. Block said. "This will need immediate action in both the central Atlantic, to reduce the loss of the big fish while hunting, and in the Gulf of Mexico and Mediterranean, where tuna produce as separate populations. " Which of the following is NOT true according to this passage? | [

After they had heated up the oven, they put the chicken and the pan on the center oven rack and set the timer. Then, as they peeled potatoes and carrots to go with the chicken, Amy, Joe and Cindy talked about dinner. Amy said, "Joe, this is too much food for you, me and little Cindy to eat in one night. We'll have leftovers. What can we do with the leftover chicken?" Joe said, "We could make chicken sandwiches or chicken and rice." Amy said, "How about chicken soup?" Cindy said, "I like chicken with Thai noodles with red peppers. We haven't made those in a long time." "That sounds good," said Amy. "We'll make that for dinner tomorrow." "Yum!" said Joe.

mmlu_train_41938 | Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms. Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a $10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to "speak" with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees----anywhere at all! Because of the many changes in computer technology , laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too. At Westlake College, more than 60 percent of the staff use computers.

mmlu_train_6989 | Robots have proved to be valuable tools for soldiers,surgeons and homeowners hoping to keep the carpet clean. But in each case,they are designed and built specifically for the job. Now there is a movement under way to build multipurpose machines-robots that can move about in changing environments such as offices or living rooms and work with their hands. All-purpose robots are not,of course,a new idea."It's been five or 10 years from happening for about 50 years,"says Eric Berger,co-director of the Personal Robotics Program at Willow Garage,a Silicon Valley organization. The delay is in part because even simple tasks require a huge set of capabilities. For a robot to fetch a mug,for example,it needs to make sense of data gathered by a variety of sensors-laser scanners identifying potential blocking objects,cameras searching for the target,force feedback in the fingers that grasp the mug,and more. Yet Berger and other experts are confident that real progress could be made in the next decade. The problem,according to Willow Garage,is the lack of a common platform for all that computational effort. Instead of enlarging the capabilities of a single machine,everyone is designing robots and the software to control them,from the ground up. To help change this,Willow Garage is currently producing 25 copies of its model PR2 (for"Personal Robot 2"),a two-armed,wheeled machine that can switch off the electricity,open doors and move through a room. Ten of the robots will stay in-house,but 10 more will go t o outside research groups,and everyone will share their advances. This way,Berger says,if you want to build the robotic equivalent of a Twitter ,you won't start by constructing a computer."You build the thing that's new." According to Willow Garage,we will make real progress in building all-purpose robots if . | [

mmlu_train_67224 | Experts recently suggested that teens should start adopting early bedtimes. Before you dismiss it as a habit suited only for young kids, consider that there are serious advantages in being well-rested. And now, even more research suggests that putting phones away before going to sleep is important to teens' well-being. A new study from Seton Hall University School of Health and Medicine Science found that 62 percent of kids used their smart phones before bed, and it's causing less sleep and poor performance in school. Those teens who text before bedtime tend to go to sleep later, and get up later in the morning. Such behavior can be associated with mental health issues like depression or anxiety. Besides, once teens do receive a text, experts found, they tend to respond right away. Then the text conversation continues -- resulting in an even later bedtime. The study's co-author Dr. Peter Polos says this leads to excessive stimulation at night. Light from electronic devices can block the secretion of melatonin -- a hormone that promotes sleep, which makes sleep difficult in the face of overuse of smart phones at night. It's true! More screen time means less sleep time; other studies have suggested the same idea. As for a final piece of advice, Dr. Sushanth Bhat says, since getting the proper amount of sleep is very important for brain development and learning in the teenage years, our study should encourage parents and guardians to limit adolescent smart phone usage at night. Keep in mind that teens aren't the only ones addicted to their phones! Adults can also benefit from setting a tech curfew for themselves. After all, kids learn by example!

mmlu_train_32461 | A California man who was feeling sick almost died recently from a shocking cause. 26-year-old Luis Ortiz went to a hospital because of a headache and nausea(,). When doctors examined him, they were shocked to find a tapeworm larva in his brain. The story gets stranger. The larva was still alive. The creature had caused a cyst to form inside his head. The cyst was restricting the flow of liquids to different areas of his brain. The situation was so serious that doctors said they had to perform an emergency operation to remove the larva. A doctor who operated on Ortiz told him he had only 30 minutes to live. When the doctor pulled the worm out of his head, it was still moving. Luis Ortiz was a student at California State University in Sacramento. He began experiencing headaches in late August. But Ortiz said he did not think the headaches were serious. In September, he visited a friend and his parents in another city. That is when the pain got worse. His mother saw Ortiz throwing up and took him to a hospital emergency room. The doctors saved Ortiz's life. However, the surgery also affected him. Ortiz had to drop out of school and move back home. For now, he is not permitted to work or drive a vehicle. The U.S. Centers for Disease Control and Prevention says the U.S. has about 1,000 reported cases of tapeworms each year. The CDC adds that tapeworms are more common in developing countries with poor public health systems. The best way to avoid a tapeworm infection is to wash fruits and vegetables. Also, make sure meat is cooked thoroughly. The CDC suggests cooking all meats to an internal temperature of at least 63 degrees Celsius.

As it turned out, the professors at Geneva Medical College were not fools. They allowed Elizabeth Blackwell to study medicine. In 1848, a year before Elizabeth would graduate, a typhoid epidemic broke out in New York. Elizabeth wrote to Emily. "There's an outbreak of typhoid, and I am going to help. It is dangerous, so if I should not survive, please do me the honor of studying medicine yourself." Emily replied, "Encouraged by your dream and success, I have decided to study in medical school, as well." Having survived the disease, Elizabeth tried to set up a private medical practice.
