mmlu_train_55894 | Winter is dangerous for drivers because it's so difficult to know what is going to happen and accidents take place easily. Bad weather can be waiting to meet you. Ice might be hiding under the snow, waiting to send you off the road. The car coming towards you might suddenly move across the road. Here are two rules for driving safely on icy roads: Rule Number One is to drive smoothly. Irregular movements can make a car very difficult to manage. So each time you either turn the wheel, touch the brake or increase your speed, you must be as gentle and slow as possible. Just imagine you are driving with a full cup of hot coffee on the seat next to you. You should drive carefully enough in order that you wouldn't get the coffee out of the cup. Rule Number Two is to pay attention to what might happen. The more ice there is, the farther you have to look down the road. Test how long it takes to stop by gently braking. Remember that you may be driving more quickly than you think. Generally speaking, allow double your normal stopping distance when the road is wet, three times this distance on snow, and even more on ice. Try to stay in control of your car at all times, or you will get into trouble. Driving in winter is dangerous because _ . | [

mmlu_train_67004 | 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. From this passage we can infer_. | [

mmlu_train_6373 | In my first week as a graduate student at Cambridge University in 1964 I met with a fellow student, two years ahead of me in his studies; he was unsteady on his feet and spoke with great difficulty. This was Stephen Hawking. I learned that he had a bad disease and might not live long enough even to finish his PhD degree. But, amazingly, he has reached the age of 73. Even mere survival would have been a medical miracle, but of course, he didn't merely survive. He has become arguably the most famous scientist in the world for his brilliant research, for his bestselling books, and, above all, for his astonishing victory over hardship. Stephen received his "death sentence" in 1964, when I thought it was hard for him to go on with his study. Stephen went from Albans School to Oxford University. He was said to be a "lazy" undergraduate, but his brilliance earned him a first-class degree, an "entry ticket" to a research career in Cambridge and a uniquely inspiring achievement. Within a few years of the burst of his disease he was wheelchair-bound, and his speech was so unclear that it could only be understood by those who knew him well. But his scientific career went from strength to strength: he quickly came up with a series of insights into the nature of black holes (then a very new idea) and how the universe began. In 1974 he was elected to the Royal Society at the exceptionally early age of 32. The great advances in science generally involve discovering a link between phenomena that were previously conceptually unconnected -- for instance, Isaac Newton realized that the force making an apple fall to earth was the same as the force that holds the moon and planets in their orbits. Stephen's revolutionary idea about a link between gravity and quantum theory has still not been tested. However, it has been hugely influential; indeed, one of the main achievements of string theory has been to confirm and build on his idea. He has undoubtedly done more than anyone else since Einstein to improve our knowledge of gravity and he is one of the top-ten living theoretical physicists.

mmlu_train_29264 | Dogs are known for a strong sense of smell. Their noses can be trained to identify different smells. Dogs are often used in search and rescue operations and to sniff for things like drugs and explosives. Some dogs have even been trained to sniff for cancer in people. Researchers have been trying to reproduce the extraordinary sense of smell that real dogs are born with. Now, officials at the Glasgow airport in Scotland are testing a new security device called an "electronic sniffer dog". The electronic sniffer dog represents one of the latest developments in the area of smell technology. A Scottish company, Cascade Technologies, joined with the French security company Morpho to develop it. The device uses lasers to identify explosive materials in gases in the air. The purpose is to identify explosives that may be hidden on a person's body. The machine looks similar to the metal detectors now used at airports. Passengers walk through the machine as the lasers test the surrounding air. People are not required to take off their coats, belts or shoes as part of the security process. And, unlike full-body scanners, the new device does not show images of the passengers. Officials at Cascade Technologies say the machine can process one person per second and produce almost immediate results. They say future development could cut security processing times at airports by screening all passengers at walking speed. Professor Yushan Yan, the head of Chemical and Environmental Engineering at the University of California, Riverside, points out that unlike real dogs, electronic devices do not get tired or need to be walked or require food and water. Professor Yan says real dogs also have other needs. "They also need very extensive training that could be expensive. And when they work they have to have a very skilled handler around them." But Professor Yan says there is an important area where man's best friend still wins compared to technology. "In terms of sensitivity and selectivity, the current technology out there is still _ . The real dog has amazing capability of identifying some really minor amount of explosives." Which of the following is true of the electronic sniffer dog? | [

mmlu_train_65581 | A four-wheeled robot,known as Rover,has been tested by a team at Sydney University.It was used to move a herd of cows from a field to a dairy . Researchers were amazed at how easily cows accepted the presence of the robot.They were not disturbed by it and the gathering process was calm and effective.Because the robot moved in a steady manner it allowed cows to move at their own speed,which was important in reducing injuries among cattle,said Dr Kendra Kerrisk,dairy researcher and associate professor. The robot was adapted from one that was already being used to monitor fruit and trees on farms.A team at Sydney University's Centre for Field Robotics improved the robot so that it could be put in a field with cows in order for the researchers to gather data on robot--cow interaction. The robot needs to be operated by a human but it's hoped that in the future a version can be developed that will be fully automated.As well as gathering cows a new version could also collect information useful for farmers. Using robots to get cows to the dairy will be better for their well-being."The research is in its very early stages but robotic technologies certainly have the potential to transform dairy farming,"said Dr.Kerrisk."When we have discussed this concept with farmers they have been extremely excited and we have had a series of calls and emails asking how they can get hold of one,"she added. The robot could also cut down the number of accidents involving humans on farms.Most dairy farmers in Australia use bikes to round up their cattle and they are one of the leading causes of injury.The team hopes that by using the robot to do the job instead,accident rates could fall.

mmlu_train_17364 | A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to evade policemen after a bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into the home of Mary Parnell. Police say he didn't touch Parnell but that she died after suffering a heart attack that was caused by terror. Can the guy be held responsible for the woman's death? Prosecutors said that he can under the state's murder rule, which allows someone to be charged with murder if he or she causes another person's death while committing or fleeing from a severe crime like robbery--even if he or she doesn't kill someone on purpose. But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women's Hospital in Boston. Absolutely, no question about it. The body has a natural protective method called the fight-or-flight response , which was originally described by Walter Cannon,the chairman of Harvard University's physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the autonomic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to primitive humans. However, in the modern world there is obvious decline of the fight-or-flight response. The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is toxic in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death. Kidney failure, liver failure, those things don't kill you suddenly. By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in intercourse or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, "I can die now", and then he dropped dead. For about seven days after the 9/11 terrorist attacks on the World Trade Center and Pentagon there was an increase of sudden cardiac death among New Yorkers. What activity can we infer is less likely to damage the organs? | [

mmlu_train_88528 | Do you know why you sleep? You may think it's because you're tired. Or perhaps you've been told sleep is good for you. Yet no one knows exactly why or how people sleep. Until the early 1950s, most scientists thought the body and brain rested during sleep. Then a scientist watched people sleep. He noticed that during periods of between 5 and 30 minutes each, sleepers' eyes made rapid movements, as if they were watching something. He called these periods REM sleep, for Rapid Eye Movement. Periods when sleepers' eyes did not move he called non-REM sleep. Whenever the scientist woke people during REM sleep, they were having vivid dreams. Measurements showed that sleepers' pulses went up quickly during REM sleep. Their breathing, heartbeat, and the blood going to the brain also increased. Far from being a time of rest, REM sleep is a time when the body is hard at work. Scientists still don't know the reason for this. Some believe REM sleep makes learning easier. Babies spend a lot of time in REM sleep. Because of this, some scientists believe that REM sleep helps the brain grow. Others think REM sleep is a time for the brain to empty the day's garbage. One thing all the scientists agree on is that sleep is necessary. Without enough sleep, people make mistakes. Most major car accidents happen during the early morning hours, when people are sleepiest. You can decide from the article that REM sleep _ . | [

mmlu_train_6791 | Sports can help you keep fit and get in touch with nature.However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment. Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water.Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses in good condition.This causes major environmental effects.For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas. There are many environment-friendly sports. Power walking is one of them that you can take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse.Simple and free, power walking can also keep you fit.If you walk regularly, it will be good for your heart and bones.Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control. Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials.But the final goal should be "green gyms".They are better replacements for traditional health clubs and modern sports centers.Members of green gyms play sports outdoors, in the countryside or other open spaces.There is no special requirement for you to start your membership.And best of all, it's free.

mmlu_train_19820 | The first step in exercising for most people is determining whether or not they should. This is particularly true with anyone over thirty-five, especially if they have been heavy smokers. Likewise, young adults who have been very inactive should proceed slowly and with caution. A physical evaluation from a physician is recommended, preferably one that includes an exercise-stress test. While a person is exercising, a stress test detects cardiovascular problems that might not show up when the body is at rest. This is done by monitoring blood pressure, pulse rate, oxygen consumption, and the heart's electrical activity while exercising. Whatever exercise program is selected, it is important to start with warm-up periods. These should include stretching exercises, jumping jacks, or active walking. The idea is to increase heart rate and circulation slowly without placing a sudden strain on the heart or the muscles that are starting to work. The next phase in developing an exercise program is to determine the amount of exercise that is enough to condition the muscles and cardiovascular system without excessively exhausting the body. This involves taking one's pulse and finding one's target zone. This target zone, or safe-training pulse rate, is established by subtracting one's age from 220 and then taking 60 percent to 80 percent of that total. If you are just starting to exercise, 60 percent is recommended; 80 percent is recommended if you are already in good condition. Who is the intended reader of the passage? | [

mmlu_train_42771 | "Children should not be left unsupervised to play with a dog." say experts in this week's British Medical Journal. Their advice is part of a review aimed at doctors who deal with dog bites. "Dog bites and maulings are a worldwide problem, particularly in children." write Marina Morgan and John Palmer. Every year 250,000 people who have been bitten by dogs attend minor injuries and emergency units in the United Kingdom, and half of all children are reportedly bitten by dogs at some time, boys more than girls. Accurate death figures are difficult to obtain, but in the past five years, two to three cases a year have made news headlines. Based on the latest medical evidence, _ advise doctors how to examine and treat a patient presenting with a dog bite. They discuss the risk of infection and when to refer to specialist care. For travelers bitten abroad, they suggest assessing the risk of rabies . In terms of prevention, they suggest that children should be taught to treat dogs with respect, avoid direct eye contact, and not tease them. They should be taught not to approach an unfamiliar dog; play with any dog unless under close supervision; run or scream in the presence of a dog; pet a dog without first letting it sniff you; or disturb a dog that is eating, sleeping, or caring for its babies. "Dog owners also need to change their behavior", says Rachel Besser, a children's doctor and lifetime dog owner, in an article. "It is clear that not all dog owners appreciate that children should not be left unsupervised with a dog", she says. Just as some parents are obliged to take parenting classes, she would like to see compulsive classes for expectant dog owners to teach them about the responsibilities of dog ownership. Educational programs are also needed to teach children about some precautionary behaviors around dogs. Finally, she would like to see animal doctors advising dog owners about bite prevention, and doctors promoting bite prevention when treating patients who have been bitten by dogs.

mmlu_train_26995 | Scientists in Argentina have created the world's first cow to own two human genes that will enable it to produce human-like milk, which is matchless up to now. It is a breakthrough in the area of clone. Genetic engineering was used to introduce the "mothers' milk" genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires. As an adult, the cloned cow "will produce milk that is similar to humans" in what will prove "a development of great importance for the nutrition of infants", it said in a statement. "The cloned cow, named Rosita ISA, is the first one born in the world that owns two human genes that contain the proteins present in human milk," the statement said. In April, scientists in China published details of research showing that they had created GM Holstein dairy cows which produced milk containing proteins found in human breast milk. But the Argentine team says the Chinese only introduced one human gene, whereas their research involved two genes meaning the milk will more closely resemble that of humans. Rosita ISA was born on April 6 and was delivered by Caesarean section because she weighed around 100 pounds, roughly twice the normal weight of Jersey cows. Adrian Mutto, from the National University of San Martin said "Our goal was to raise nutritional value of cows' milk by adding two human genes, the protein lactoferrin and lysozyme, which can provide newly-born babies with anti-bacterial and anti-viral protection." Cristina Kirchner, President of Argentina, said that the scientific institute "makes all proud." She also revealed that she had rejected the "honor" of having the cow named after her. "They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more appropriate to call it Rosita."

Because of the disease, Mattie had to get around in a wheelchair, but it did not stop him from staying positive and inspiring others with his message of peace. As a best-selling author and role model, Mattie provided a voice for people who suffer from muscular dystrophy. He spoke to people about the disease and about his dream for world peace. "Mattie was something special, something very special," said Jerry Lewis, the chair of the Muscular Dystrophy Association, a group that works to find a solution to the disease. "He was an example that made people want to reach for the best within themselves." Mattie moved many people through his speeches and interviews, but he may have touched the most people through his poetry. During his life, Mattie wrote five books of poetry. Three of those books were The New York Times best-sellers. His books all had the word "Heartsongs" in the title. Mattie called his inner voice that encouraged him to work for peace his "Heartsongs". When his first book came out, just 200 copies were printed to be handed out to friends and supporters. But after the news of the book spread, 500,000 more copies were printed. People think Mattie's poems are very thoughtful. Mattie first started writing poetry at the age of 3 to help him face the death of his brother, who also suffered from muscular dystrophy.

mmlu_train_44910 | A kitchen that gives step-by-step cooking instructions in French could inspire a revolution in language learning in the UK. By using a new technology, it speaks to you as you prepare a French dish. The kitchen breaks new ground by taking language learning out of the classroom and linking it with an enjoyable and rewarding real-life activity. The new kitchen is designed to be used in schools, universities and even people's homes. It could also be an existing kitchen. The first version of the technology was tested in the kitchens of project partner Newcastle University. The kitchen could be available for schools and universities, and for the UK market by the June of 2014. The Newcastle University team is now working on ways to put it on the market. And the European Union has given money to begin programs in six other languages, including English Italian and Spanish. Finally, versions could be developed for any language cuisine in the world. Professor Paul says, "By international standards, the UK students are now poor when it comes to learning languages--a problem that certainly has an economic influence. We believe that developing skills in a country's language and its cuisine will help change the trend." [( )] On a computer fixed into the kitchen, the user first selects the French recipe they want to follow. Digital sensors built into dishes, containers and other equipment then communicate with the computer to make sure the right instructions are given at the right time, the user can ask the computer to repeat an instruction, or translate it into English, simply by pressing the touch screen. After cooking, the user can test what they have learned by carrying out a short test on the computer. All grammar and vocabulary has been carefully selected to make sure that using the kitchen adds to basic proficiency in understanding French. Now three easy-carrying versions of the kitchen are being prepared. They're to be fixed in Newcastle University and at Institute Francais, a London-based charity devoted to teaching the French language. [( )] Which of the following is TRUE about the kitchen? | [

mmlu_train_20543 | The last five pounds. The vanity pounds. The dream weight. The fantasy weight. The high school weight. Yes, many names are given to the weight - the five pounds - that seems just out of reach no matter how much we exercise and improve our eating habits. But why is it out of reach? Is it all in our heads? Or is it because the body has a set-point or ideal weight - a weight to which it doesn't want to give in? "There is no such thing as ideal body weight," says James, author of "Weight Loss That Lasts." "But your body does resist you when you are trying to lose weight. It gets used to a certain weight over a long period of time and then will defend that weight." In other words, the body's "set point" can be lowered - or raised, he says, but it takes time to reset that new weight. That period of time is at least six months. "I often ask patients, 'What is the lowest stable weight of your adult life?' to get an idea of what is realistic" in terms of weight loss and maintenance , James says. He refers to the body's refusal to change, weight-wise, as an "biological control system that prevents us from going hungry and dying - part of our primitive biology." Some people might get down to their dream weight for a short period but then can't keep it long because the calorie limits are too strict once the body starts defending itself against weight loss. "That's why it's important to set realistic goals," he says. "The idea of the 'ideal weight' or 'dream weight' is really just a useless exercise." But let's say your goal is realistic and has been set by a nutritionist or other weight-loss professionals and _ . What could be going on? The reason is that you need fewer calories the less you weigh. So if you want to continue to drop weight, you have to drop calories and increase calorie-burn. James encourages people to tell the difference between weight loss goals for health reasons and those to do with vanity. "They are different issues," James says. "One is where important health benefits are seen and the other is about vanity - wanting to look good in a bathing suit." According to the passage, what is James' most possible attitude towards t weight loss for vanity? | [

The ban is aimed at controlling the number of deaths from smoking-related diseases, running at a million deaths a year.That figure is predicted to double by 2020.The new smoking ban is an attempt to prevent that prediction coming true. The new rules forbid people from smoking in places like hotels, railway stations or theatres, but not including the office.Employers can warn their staff of the dangers of smoking but cannot forbid them from smoking at their desks. But the new rules have been criticized because they do not describe in detail the punishments for businesses or individuals who _ them.Quite many smokers do not seem to take much notice of them.Often you find people smoking at next table while you are eating your meal or having a drink in a bar.In bus stops as well as in railway stations smoking can also be seen here and there.Business owners are also angry at the efforts to force them to ban smoking on their premises , because many customers refuse to go to restaurants or places of entertainment where smoking is forbidden. It appears that many Chinese people are unaware of the dangers of smoking.Research suggests that only one in four knows the harm cigarettes can cause.Officials say they have to try to persuade people not to smoke to try to reduce the numbers dying from smoking-related diseases.At the same time, however, the local governments make a lot of money from the sales of cigarettes by the state-owned firm that makes and sells tobacco products throughout the country.

What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity of our earth. Wilson begins with an open letter to the pioneer in environment protection, Henry David Thoreau. He compares today's Walden Pond with that of Thoreau's day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Can the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future? Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas. At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may as well read and act on the ideas in this book. We learn from the text that Wilson cares most about _ . | [

mmlu_train_59381 | Speeding off in a stolen car, the thief thinks he has got a great catch.But he is in for an unwelcome surprise.The car is fitted with a remote immobilizer, and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again. The idea goes like this.A control box fitted to the car contains a mini-cellphone, a micro-processor and memory, and a GPS satellite positioning receiver.If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted. In the UK, a set of technical fixes is already making life harder for car thieves." ," says Martyn Randall, a security expert.He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools.But only if the car is more than 10 years old. Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code sent out by the ignition key.In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys.And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system. If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen.The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal. Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle's movements via the car's GPS unit.

mmlu_train_31855 | WASHINGTON--A baby born with the virus that causes AIDS appears to have been cured, scientists announced Sunday, describing the case of a child from Mississippi who's now 2.5 and has been off medication for about a year with no signs of infection. There's no evidence that shows that the child will remain healthy, although complex testing uncovered just traces of the virus' genetic material still lingering . If so, it would mark only the world' s second reported cure. Specialists say Sunday's announcement, at a major AIDS meeting in Atlanta, offers promising clues for efforts to remove HIV infection in children, especially in African countries where too many babies are born with the virus. "You could call this about as close to a cure," Dr. Anthony Fauci of the National Institutes of Health, who is familiar with the findings, told The Associated Press. A doctor gave this baby faster and stronger treatment than usual, starting a three-drug mixture within 30 hours of birth. That was before tests confirmed the infant was infected and not just at risk from a mother whose HIV wasn't diagnosed until she was in labor . "I just felt like this baby was at higher-than-normal risk, and deserved our best shot," Dr. Hannah Gay, a pediatric HIV specialist at the University of Mississippi, said in an interview. That fast action apparently knocked out HIV in the baby's blood before it could form hideouts in the body. Those so-called reservoirs of dormant cells usually rapidly reinfect anyone who stops medication, said Dr. Deborah Persaud of Johns Hopkins Children's Center. Next, Persaud's team is planning a study to try to prove that, with more aggressive treatment of other high-risk babies. "Maybe we'll be able to block this reservoir seeding." Persaud said. No one should stop anti-AIDS drugs as a result of this case, Fauci warned. Which of the following is NOT true? | [

mmlu_train_45734 | Monkeys , face to face DISCOVER magazine once reported on a curious event in the woods : a group of monkeys applied mud to their faces in order to keep away insects , but when they were done they seemed to have lost their ability to recognize each other ---two monkeys that were supposed to be friends even started fighting. "Faces are really important to how monkeys and apes can tell one another apart," explained Michael Alfaro, a biologist at University of California, Los Angeles (UCLA), to the New York -based International Science Times . This is quite different from many other animals , which depend heavily on smells. Since faces play such a crucial part in the social lives of monkeys , could this explain why certain monkey species have such colorful faces while others have simpler, plainer ones ? To test this theory , a group of researchers from UCLA studied 139 monkey species , mainly from Asia and Africa, and analyzed hundreds of headshot photos of those monkeys from their databases. It was found that species that live in larger groups have faces with more complex color patterns than those that live in smaller groups. According to Live Science, researchers believe that this is nature's way of making it easier for monkeys to recognize each other since those living in larger groups have to distinguish between a greater number of faces. This is actually not that hard to understand . Just imagine if there were 10 people standing in front of you, all wearing white clothes. It would be much more difficult to tell them apart than if they wore clothes with colorful patterns. However, if there were only two people that you had to identify, a lack of color wouldn't be much of a problem. Apart from the need to recognize group members , researchers found that geography and environment also affect monkeys' facial colors. Species that live closer to the equator in thick, humid forests were found to have darker faces than those who live in dry areas further away from the equator. This is because darker faces help camouflage the monkeys in the woods so that they go unnoticed by predators . What is article mainly about? | [

mmlu_train_27858 | prefix = st1 /West Virginia--Public schools are using a dance video game to help get students in shape. In these schools, students are often told to turn off their video games and get some exercise. The schools have found a new way for their students to work out while playing a new video game. West Virginiais one of the heaviest states in the country. About half of its fifth-graders are considered to be overweight, and their parents are worried about that. To get them moving on a healthier path, the state's public schools are using a video game called "Dance Dance Revolution". To use the game, players should stand on a special mat in front of a TV screen. Following arrows on the screen, players must move their feet to the specific symbols on the mat. Players must move quickly, touching symbols on the mat at just the right time. With each song, they get more exercise. "It we can get children to change their behavior at a young age, they will hopefully grow up to be healthy and active adults," said Carl Callison of Mountain State Blue Cross, a health care company. West Virginiais ranked among the top three heaviest states. About a third of West Virginians are considred to be obese. Even more are considered to be overweight. Extra weight can lead to serious health problems such as high blood pressure, diabetes, some cancers, and many other health issues. "One out of three children born in West Virginia today will have diabetes by the time they grow up," said Nidia Henderson, a manager for the public employees' insurance program. "That's a terrible thing and not acceptable." All ofWest Virginia's 157 middle schools are using the video game. School officials hope that all public schools in the state will use the game within the next three years. However, officials emphasize that the game is not meant to _ physical education and health classes. The game will be part of physical education classes and after-school programs.

mmlu_train_65596 | Music is really powerful. Without music, movies would lose some of their attraction. No one disagree with the powerful effect music has on individuals. Whether this effect is positive or negative, however, often depends on the type of music listened to. And researches have shown that certain types of music own the ability to relieve one's anxiety, improve brain development in children, uplift one's memory and help patients to recover...just to name a few. It should come as no surprise then, that researchers from the Tufts University have found that background music has the ability to directly affect one's eating habits as well. They counted the bites of food individuals took at meals while listening to different types of music. The diners "ate at an average rate of 3.9 bites per minute", with about a third of the diners requesting more food after clearing their plates. On the other hand, with "spirited tunes, "the diners "sped up to an average of 5.1 bites per minute! "Not surprising however, when "calming flute instrumental" were played, the eating speed of the diners slowed "to 3.2 bites per minute--and the bites became smaller". They didn't request second helpings and praised that the food tasted better. Studies have clearly stated that one safe way of losing weight includes eating slowly. Since it takes about 20 minutes for your stomach to tell the brain that it's full, eating slowly will help you to eat to satisfaction--without overdoing it. With this important piece of information then, it leads one to believe that with the use of calming background instrumental music, one can slow their food digestion, "retraining" both the stomach and the brain to take in less food which could lead to weight lost. Is there any truth to this theory? One will never know unless they try it themselves. Even if it doesn't work for you, at least you'll achieve a bit of relaxing and pleasant environment during your meal periods. A great meal with great music--who could ask for anything more? Which of the following is NOT the benefit of listening to certain types of music according to the passage? | [

mmlu_train_86376 | A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment? As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden and wait for it to flower . A biodegradable mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage users to recycle. Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any poisonous chemicals. British researchers used the new material to develop a phone cover that includes a sunflower seed .When this new type of cover turns into waste, it forms nitrates . These feed the seed and help the flower grow. Engineers have designed a small transparent window to hold the seed. They have made sure it only grows when the phone is thrown away. "We've only put sunflower seeds into the cover so far. But we are working with scientists to find out which flowers would perform best. Maybe we could put roses in next time." said one scientist. As phone technology is developing so quickly, people are constantly throwing their mobiles away. This means producers are under pressure to find ways of recycling them. Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can change this, according to the scientists. ,A, B, C, D,. (10) This type of research is done because _ . | [

We roar to tell each other where we are and to warn strangers to stay away. Meet my new baby brother. His name is Leon. See the spots on his fur? We lions are born spotted or striped . As we grow older, the spots gradually disappear. Lionesses usually spend their entire lives with their birth pride, but Leon will leave when he is about three years old. He'll run around with a male friend or relative for a few years until they take over a pride of their own. But for now, we have lots of fun together.

mmlu_train_73823 | Most of us probably live without vegetables, but a world without chocolate? Now that would be hard! According to chocolate makers it could happen if we don't act soon. There are two main causes of the chocolate shortage --- chocolate's growing popularity and less production of cocoa, the plant from which chocolate is made. With more and more people in India and China loving chocolate, not much can be done about the first cause. Therefore, the only thing we can do is to increase cocoa production. However, new plant diseases and little rain in Ivory Coast and Ghana, the world's largest producers, have reduced cocoa production by 40 percent in the past 10 years. What's worse, many cocoa farmers in Africa and other cocoa-producing countries like Indonesia and Venezuela are changing to easier-to-grow crops such as corn or rubber. This way, the farmers can make more money. To prevent more farmers from changing, researchers at the newly opened International Cocoa Control Centre, in the UK, are trying to create new cocoa plants that are stronger and faster growing. But first they must make sure the new plants are safe to grow. This takes a long time. First, each new plant is stored at the Control Centre for six months to make sure it is healthy. It is then planted in the Centre's fields, studied and tested for another two years. Only after scientists are certain that they're disease-free, will the plants be sent to farmers in West Africa or wherever else they are needed. To create new stronger types of cocoa, scientists at the Centre are combining the best parts from different cocoa plants. Though the world is facing a serious chocolate shortage, there is now hope!

At age 15,Winter Vinecki has already had more successes than most people have in their lifetime."I recently completed a marathon on all seven continents and became the youngest person in the world to do so.And I was really doing this for my dad." Doctors discovered that Winter's father had a rare and deadly form of prostate cancer when she was nine years old.Then he died 10 months later."When he was first diagnosed with prostate cancer I immediately knew I had to do something to help him.That's when I formed Team Winter for prostate cancer research and awareness." Through Team Winter and social media,Winter Vinecki has raised almost 500,000 dollars.She has taken prostate cancer education worldwide through foot races called marathons,on seven continents.In the United States she travels continually to talk about prostate cancer and urge others to act. Winter Vinecki attended a conference recently in Los Angeles,California and spoke at the conference as one of several teenagers who spoke about young people who were living extraordinary lives. "So prostate cancer is much more common but men don't want to talk about it.So that is why a ten-year-old girl had to go out there and start talking about it for them."

The Romans had warm public baths. In some baths, as many 3,000 persons could bathe at the same time. Treating disease by taking bathing has been popular for centuries. Modern medical bathing first became popular in Europe and by the late 1700's has also become popular in the United States. For many years frequent bathing was believed to be bad for one's health. Ordinary bathing just to keep clean was avoided , and _ was often used to cover up body smells! By the 1700's doctors began to say that soap and water were good for health. They believed that it was good for people to be clean. Slowly, people began to bathe more frequently. During the Victorian Age of the late 19th century, taking a bath on Saturday night became common. In the United States ordinary bathing was slow to become popular. During the 18th and early 19th centuries, many Americans were known as "The Great Unwashed!" In one American city , for example, a person was only allowed to take a bath every thirty days! That was a law! Frequency of bathing today is partly a matter of habit.
