mmlu_train_15950 | High in the sky, a group of birds fly past. The 5-foot-tall creatures are whooping cranes, the tallest birds in North America noted for its loud call. The wild animals appear to be following much larger birds. But those aren't birds at all. They are three-wheeled aircraft called trikes , and the pilots flying them are wearing white helmets and white gowns. That plan might sound like a stupid idea, but it's not. The pilots are from an organization called Operation Migration. They are helping the whooping cranes learn to migrate, or move from one area to another when the seasons change. The cranes are endangered. In 1941,the species had dwindled to roughly 20 birds because of hunting and habitat loss. US wildlife officials counted 149 whooping cranes in November 1995,the most since the American government began taking censuses in the 1930s.Today,about 380 remain. In the fall, whooping cranes are supposed to migrate south. However, many of them don't know how. "With so few birds left, young whooping cranes typically don't have parents around to teach them," explains pilot Joe Duff. That's where the trikes come in. Each October, pilots dress up as whooping cranes and take to the skies in Wisconsin. The young birds follow them because they think the trikes are big whooping cranes. It takes about three months to reach south--with plenty of rest stops on the way. The pilots lead the cranes to refuges, or protected areas, in Florida. This spring, the birds will migrate north by themselves--no trikes needed! "It's nice because you know the birds are going to make it," Duff told WR News. We can learn from the passage that whooping cranes . | [

mmlu_train_13084 | Two brightly colored butterflies have just flown by. They seems to be exactly alike, but actually one is a little larger than the other. The larger insect has a wingspread of up to four inches. The smaller one has a wingspread of less than three inches and also a black line on its back wings. At first sight, it is hard to tell them apart. Would you guess from this that they are different-sized butterflies of the same species? Or that they are different species of butterflies but close relatives belonging to the same family? If you said yes to either question, you would be wrong, for these look-alikes belong to quite different families. The larger insect is the monarch butterfly . As a baby insect, the monarch feeds on milkweed, which seems to give the monarch a disagreeable taste and smell. The bright coloring of the monarch acts as a warning sign to its enemy. Birds that eat butterflies soon recognize the monarch and quickly learn to leave it alone. The smaller insect is the viceroy , which feeds on the leaves of trees. Birds would find this insect tasty, but because it looks like the monarch, birds keep away from it. The viceroy's similarity to the monarch gives it some protection from its enemies and helps it survive. There are other pairs of look-alike butterflies, bees and moths. In each case, one either has a disagreeable taste or smell, or can give a painful sting . The larger is called the model. The insect that imitates this model for protection is called the mimic.

mmlu_train_46910 | All right! Enough cookies,cola, and chips! It seems that junk food is all that the children want to eat these days.Television controls their tastes.The kids see well-known personalities eating potato chips, candy and other processed food, and they want to be like their heroes.How do they do it?They eat the same food. I wish there were more characters like old Popeye , the sailor, who ate spinach and not French fries. Now I don't expect my children to eat healthy food because I like brown rice, beans, and fresh vegetables. I'm glad to cook traditional meals of meat and potatoes for them. I really can't be too upset with the kids because most adults aren't careful about what they eat. The other night, my wife and I went to a party where there was plenty to drink but very little for us to eat. They served hot dogs and hamburgers. I can't eat hot dogs, with all those preservatives , and hamburgers are filled with chemicals so that they look better. Besides the meat, they had sugar-filled cookies and cake, and of course, chips. I don't want the world to change because of me, but I think people should realize that there are alternatives to eating meat. They always tell me that I probably don't get my essential proteins.

mmlu_train_74609 | 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. Which of the following statements is not mentioned in the passage? | [

mmlu_train_28480 | Early risers are most likely to be healthy, wealthy and wise, according to the old saying. But those who are early to bed and early to rise do not always have advantages, researchers say. They have found that night owls are generally brighter and wealthier than those who are able to get up early in the morning. Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late showed the kind of intelligence to find good jobs and earn much money. Larks or "morning people", however, often get better exam results, possibly because lessons are held at the wrong time of day for night owls. The researchers examined the habits and body clocks of the young people to determine whether they liked to stay up late and sleep later in the morning, or preferred to go to bed early and were at their best state in the morning. School performance and problem solving ability, were judged and test grades in the major subjects were also taken into consideration. Jim Horne, professor of psychophysiology at Loughborough University, said: "Evening types tend to be the more creative types, the poets, artists and inventors, while the morning types are considered to be civil servants and accountants .

mmlu_train_31445 | The future of pinnipeds looks much brighter today than it once did. At one time, about 100 years ago, it seemed certain that many pinnipeds in the world would be destroyed by human hunters. Today, it appears that most species( ) of pinnipeds are out of danger. Hunting was not controlled during the 18th and 19th centuries, because little was known about the lives of pinnipeds. Whales and pinnipeds were hunted for the oil from their body fat. This oil was used in lamps before electric lights were invented. Millions of seals and other pinnipeds were used to provide oil for the lamps of the world. As a result, the numbers of many pinniped species fell rapidly. Several things happened that helped to save pinnipeds. First, species that were hunted to near extinction were left alone because their numbers were too low and the cost of hunting them went up greatly. At the same time, electric lights were invented and the market for seal oil became smaller. Finally, governments around the world made laws to protect pinnipeds. As a result of all these things, the numbers of most pinniped species have grown in recent years. With some species, such as Northern fur seals, there may be as many animals alive today as there were before all the hunting began. However, oil is still a danger to pinnipeds and all sea animals. But this time it's not because they are hunted for their oil. The oil that puts them in danger is from oil spills in the sea. The oil covers their fur and reduces their body temperatures. Oil also sticks to the foods they eat. This modern danger to pinnipeds and their environment is one we must work to prevent. It can be inferred from the passage that _ . | [

mmlu_train_12310 | Hawaii is an important trading center and about six million tourists visit there every year. With all that traffic in and out, exotic species have plenty of opportunities to reach the islands. According to biologists, exotic species are the number one threat to the state' s economy, environment, and way of life. The question in Hawaii is, can the invaders be stopped? Quarantines are one way to do this. Quarantine is the process of isolating animals or products. In Hawaii, pet dogs and cats coming into the state remain in a special holding facility for four months to make sure they don' t have rabies( ) Many agricultural products are also quarantined to see if they are carrying insect pests or plant diseases. Inspection is a second way to stop biological invaders. At airports, borders, and shipping ports, inspectors examine passengers and their baggage to see if they are carrying exotic species. The inspectors also destroy fruits, vegetables, or other goods that might be carrying harmful pests or diseases. Specially trained dogs also smell goods in the ship for exotic species. What if an exotic species slips by inspectors? Then efforts are made to control the invader. In Hawaii,government agencies control invaders by setting livetraps around wildlife shelters and other places. At Haleakala National Park employees have built miles of fences to keep out exotic pigs and goats. For years these animals ate and walked over native rain forest plants, hut the fences have helped reverse( )this damage. Now native plants grow in places that were bare rock only a short time ago. In some cases biological control helps to solve the exotic species problems. It is the science of controlling one invader with another. In the early 1900s, several exotic predators were imported to Hawaii to eat a harmful exotic pest called the sugarcane leafhopper. The insect was destroying 70,000 tons of sugar a year ,but the predators brought it under control. The efforts of these scientists and other people are vitally important. In Hawaii alone,10,000 different species of native plants and animals still need to be protected. Many of these are found nowhere else on earth. By stopping the spread of the biological invaders, we not only protect ourselves, but we also protect the many other native species that make our planet such a special place to live. Which of the following statements is true? | [
"Animals and products are put in quarantines before entering Hawaii.",

mmlu_train_45100 | Back those photos up The images were striking. Homes on the East Coast were washed away by Superstorm Sandy. People were in tears, picking up faded photographs, among their only remaining possessions. If that doesn't move you to get serious about safekeeping your lifetime of memories, what will? The digital age offers tools never imaginable before--including one-click access to a lifetime of family photos. Here is a brochure on how to back up your photos and save them online, where they can live forever and be accessible in good times and bad. Scanning The first step for those old photos is to scan them and save them to a digital format. Most printers come with scanners these days, so that's an easy but extremely time-consuming step. Storing the photos With your scans in place, import the photos into your computer, and back them up. You could make multiple copies of the disks and spread them to loved ones. Or you could choose external hard drives or USB thumb drive, and add your photo and video collection from your computer. Online backup If you need lots of space, look at a pure online backup service, Caronite. Caronite backs up 300 million files daily. Once you sign up, it starts to pick up everything you have on your hard drive. But photo collection on your computer's main hard drive charges for $59 a year. Cloud Storage For folks who don't need automatic backup, but instead want to take a more active approach, Dropbox, Google Drive and Microsoft's SkyDrive let you store files online by yourself, share and instantly access them. All offer free options--2GB of free storage for Dropbox, 5GB for Google and 7GB for SkyDrive. But if you want more, you need to pay. Bottom Line The hard drive or flash drive is the cheapest and easiest. But drives can fail. Online services are more expensive, but more secure. With more of us switching back and forth between our computers, such services are the best way to get access to our data from wherever we are. Why does the author mention Superstorm Sandy? | [

mmlu_train_74861 | Will it matter if you don't take your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfasts. The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, egg, bread and milk before going to school, he will learn more quickly and listen more carefully. The result is opposite to what some people think. Having no breakfast will not help you lose weight. This is because people become so hungry at noon that they eat too much for lunch. They will gain weight instead of losing it.

mmlu_train_45359 | Primary teachers are responsible for guiding children through the formation of many important life skills, and also watching over their students' social development. Primary teachers come into contact with about 30 students every day, and teach them a variety of subjects. Many hours are spent before and after class on planning, preparation and correction. One should be a very patient, caring, yet firm person to be able to deal with the demands of children in the four to twelve-year-old age group. Secondary teachers teach specific subjects to various groups of students. Just like primary teachers, they spend an amount of time planning and preparing lessons and correcting homework--their duties are not restricted to face-to-face teaching. Dealing with twelve to eighteen-year-olds requires a wide range of skills. If you become a primary teacher, you will need to decided whether to be a "generalist ", teaching a wide range of subjects, or a "specialist", teaching only one or two. Most primary teachers are specialists. Generalist teachers spend the greatest part of their day with one class, which means that they spend more time with the same children. Specialist teachers have more time away from their students. It is therefore very important for generalist teachers to develop a strong working relationship with their students. The unique rapport you can develop with a particular set of students is one of teaching's greatest pleasures. However, the disadvantage of primary teaching is that if you have a difficult student, you will be forced to deal with him or her, all day, every day, throughout the school year. Teachers need to work ot strategies to get themselves and their students through such difficulties. Primary teachers today are generally four-year trained. They usually do a three or four-year under-graduate degree, and if this degree does not include teacher training, they will have to undertake postgraduate study in education as well.

mmlu_train_21344 | Sleep -- or a lack of it -- is probably the most-discussed part of baby care. New parents discover its importance in those first few weeks and months after their babies were born. Actually, the quality and quantity of a baby's sleep affects the well-being of everyone in the family. So how do new parents get their children to bed through the cries? And how much sleep is enough for their children? It all depends on their children' s age. Sleeping charts that list the hours of sleep likely to be required by a baby or a two-year-old may cause concern if individual differences aren't considered. These numbers are simply averages reported by large groups of children of a particular age. There's no satisfactory number of hours required by all kids in a certain age group. Two-year-old Sarah might sleep from 8:00 pm to 8:00 am, while two-year-old Johnny is just as alert the next day after sleeping from 10:00 pm to 5:00 am. Still, sleep is very important to a child's well-being. The link between a child's lack of sleep and his or her behavior isn't always obvious. When adults are tired, they can have low energy, but kids can become overexcited, disagreeable and have extremes in behavior. Most children's sleep requirements fall within a predictable range of hours based on their age, but each child is a unique individual with different sleep needs. Here's a summary of a few ways that may help your child ease into a good night's sleep: Stick to bedtime. Consider playing soft music. Don't give your baby a bottle of milk or any sugar-containing drink to aid sleep. There isn't one sure way to raise a good sleeper, but every parent should be encouraged to know that most children have the ability to sleep well. The key is to try, from early on, to establish healthy sleep habits that may last a lifetime. How should new parents treat the sleeping charts? | [

mmlu_train_68346 | Comets are parts of our solar system. Like the planets, they go around the sun. But comets are not made of solid rocks like planets. A comet is a ball of dust, stones, and ice. Many people call comets dirty snowballs. The "snowball" may be only a few miles across. But when the sun heats the "snowball," much of it is changed to gases. The gases spread out and form the comet's head, which may be thousands of miles across. A comet moves fast in its trip around the sun. But when we see it, the comet does not seem to move. That's because it is so far away. The moon moves fast, but when you look at it, you can't see any motion . That's because the moon is far away. Each year astronomers discover new comets. Some of them are seen only once. They make one trip around the sun and then go away out into space. The sun's gravity cannot hold them. Other comets, like Halley, keep returning. They have been captured by the sun. Halley's earliest visit was probably 3,000 years ago. It may keep returning for another 3,000 years. But every time a comet goes around the sun, the comet loses part of itself. Gases and dust are pulled out of the comet. That's why Halley is now dimmer than it used to be. Next time it visits us, in 2062, it may be even dimmer. Each visit it may get dimmer and dimmer, until it finally disappears. What is this passage mostly about? | [

mmlu_train_11919 | Interactive Home-security Systems Tarik Celebi, who lives in San Francisco suburb, takes his home-security system with him to work, to dinner, just about anywhere.By his cell phone, he "arms" his home-security alarm from his car before he leaves for work.During his workday, he gets e-mail alerts every time his front door opens, even though he's miles away.If the door opens at an unusual time -say midday when no one should be coming or going - he can order a 30-second video clip from the camera that watches the door.If it's just his mother-in-law getting a package delivery, no worries. Celebi is one of the first users of the latest interactive home-security systems.In addition to sounding alarms when the house is broken into and notifying homeowners or police, as traditional systems do, the interactive systems give users new ways to remotely control their systems and their home environment.Different from traditional home-security alarms, which homeowners typically have to press buttons on a keypad to turn on before they leave their homes, the interactive systems enable consumers to arm and disarm systems from smart phones, iPads and PCs, no matter where they are. Most traditional systems are set up to sound an alarm if doors or windows are opened. The interactive systems give homeowners more options.For example, users can elect when they want to be notified.They might want an e-mail or a text every time a door is opened, or only during the hours of 3 to 4 p.m., when kids come home from school.Like Celebi, they can add cameras and get video clips when doors open.That could be helpful in making sure kids aren't bringing friends home when they're not supposed to. Nationwide, about 20% of homes have.traditional home-security systems.About half stop using them because they tire of the trouble.Being able to arm systems even while dashing to the subway or while at work will increase their usage of the new interactive systems.Although the new functions add costs to home security, the interactive-systems are believed to push home-security systems' usage rates closer to 30%, which would be a big movement for an industry that's been largely stuck at 20% for the past decade."We all know it's going to get bigger, though we don't know how long it's going to take," Eric Taylor, an officer from San Francisco Security Department says.

mmlu_train_54472 | Reading is good for you. There is increasing evidence to show that reading isn't merely a way of improving literacy and knowledge, but that it might actually be good for one's mental and physical health, too. In the age of Twitter and short attention spans, reading novels, which requires intense concentration over a long period of time, could be the antidote . Neuroscientists Baroness Susan Greenfield says that reading helps to lengthen attention spans in children and improve their ability to think clearly. "Stories have a structure that encourages our brain to think in sequence, to link cause, effect and significance," she says "It is essential to learn this skill as a small child." "In a computer game, you might rescue a princess, but you don't care about her, you just want to win," she explains, "But a princess in a book has a past, present and future. You can relate to her. You see the world through her eyes" According to professor John Stein, Oxford university, reading is far from a passive activity. "Reading exercises the whole brain," he explains. " When we get lost in a good book, we are doing more than following a story, Imaging what is happening is as good as activating the brain as doing it. In other words, our brains simulate real experiences, and it is just as if we were experiencing them ourselves. This doesn't happen when we are watching a TV or playing computer games." Getting stuck in a good novel appears to be good for one's mental health. Reading helps one not only fights loneliness, but also forget one's own problems for a while. Researchers found that just six minutes of reading could reduce stress levels by more than two-thirds, more than listening to music or going out for a walk. The concentration required to read distracts the mind, easing muscle's tension and slowing the heart rate. Reading may be good for physical health, too, by preventing brain aging and disease.

mmlu_train_22294 | Last year college students in America spent an estimated $700 on textbooks on average. The National Association of College Stores reported more than five billion dollars in sales of textbooks and course materials. The association spokesman Charles Schmidt says electronic textbooks now just make up 2%~3% of sales. But he says that is expected to reach 10%~15% by 2012. Online versions are now available for many of the most popular college textbooks. An etextbook can cost half the price of a new print textbook. But students usually lose access to them after the end of the term. And the books cannot be placed on more than one device ,so they are not easy to share. So what do students think of etextbooks?Administrators at Northwest Missouri State University wanted to find it out. Earlier this year they tested them with 500 students in 20 classes. The university is unusual. It provides laptop computers for all 7,000 of its fulltime students. It does not require students to buy their textbooks either. They rent them to save money. The school aims to save even more by moving to etextbooks. The students in the survey reported that downloading the books from the Internet was easy. They liked the idea of carrying lighter backpacks. And 56% said they were better able to find information. But most found that using etextbooks did not change their study habits. And 60% felt they read more when they were reading on paper. In all,almost half the students said they still liked physical textbooks better. But the survey found that cost could be a big influence.55% said they would choose etextbooks if using them meant their textbook rental fee would not increase. Roger Von Holzen heads the Center for Information Technology in Education at Northwest Missouri State University. He tells us that administrators are disappointed with the etextbooks now available because the majority are not interactive . He thinks growth will come when more digital books include video,activities,games and other ways to interact with the information. The technology is improving. But for now,most of the books are just words on a screen. Etextbooks are not better than paper books in that _ . | [

mmlu_train_44369 | Many grown-ups worry that spending too much time playing video games isn't good for a kid's health. But some doctors have noticed that kids who bring their game players to the hospital seem less worried about being there. They also seem to feel less pain when they are giving all their attention on a car race or other games. At a children's center in Baltimore, Maryland, young kids are finding hospital visits easier to deal with, thanks to a test program called HOPE. Patients in HOPE have a life-threatening condition where their kidneys no longer get rid of wastes from their blood. To get their blood cleaned, these kids must use the dialysis machines at the hospital three times a week, for at least three hours each time. HOPE allows kids to play Internet sports, racing, and other games with each other. They will be able to connect with kids in other hospitals who have the same problem. "We want to use the Internet to bring together kids who are ill, and let them know they are not alone," said Arun Mathews, the doctor of the program. He loved video games himself and got the idea to connect kids all over the country. Many researchers elsewhere are testing video programs that might help young patients. For example, nine-year-old Ben Duskin of San Francisco, California, who was struggling with cancer helped to design a video game where players got rid of cancer cells. That's all great news, because doctors already know that reducing pain and worry helps patients heal faster. Which of the following statements is true according to the passage? | [

mmlu_train_34771 | Why do our eyes open wide when we feel fear? And why do our eyes become narrow when we express disgust ? According to a new research, it has something to do with survival. In a recently published paper, researchers concluded that expressions of fear and disgust changed the way human eyes gather and focus light. They argued that these changes were the result of evolutionary development and were intended to help humans survive, or at least discover, very different dangers. In order to test their hypothesis ,researchers examined two dozen volunteer college students with standard eye-exam equipment, and asked them to show expressions of fear and dislike. It was found that when the students widened their eyes, more light was admitted and their field of vision was expanded. When they wrinkled their noses in disgust, their eyes narrowed. This had the effect of blocking out more light but focusing on a specific point. Although some scientists have admitted that emotional expressions are intended primarily to communicate information, expressions of fear and disgust seem to perform different visual functions. "Eye widening may help to find a potential danger that requires much attention. And this would agree with the hypothesized function of fear," said researchers. "On the other hand, eye narrowing may help to distinguish and avoid different kinds of dangers, such as disease carriers and dirty foods. And this would agree with the hypothesized function of disgust." These findings supported naturalist Charles Darwin's view that expressions are not necessarily for communication and are not arbitrary ."If our expressions were arbitrary, they would show little cross-cultural relationship." researchers said. "But actually, our expressions probably have some universal functional principles." According to the text,which of the following expresses the correct connection? | [
"Fear - eye widening - more light - a coming danger.",

mmlu_train_65422 | Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington, D.C. And on Tuesday, August 23rd, witnesses say she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she's not the only one. In the moments before the quake, an orangutan let out a loud call and then climbed to the top of her shelter. "It's very different from their normal call," said Brandie Smith, the zookeeper. "The lemurs (monkey-like animals of Madagascar) will sound an alarm call if they see or hear something highly unusual." But you can't see or hear an earthquake 15 minutes before it happens, can you? Maybe you can -- if you're an animal. "Animals can hear above and below our range of hearing," said Brandie Smith. "That's part of their special abilities. They're more sensitive to the environment, which is how they survive." Primates weren't the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard ran quickly for _ . The flamingoes (a kind of bird) gathered before the quake and stayed together until the shaking stopped. So what kind of vibrations were the animals picking up in the moments before the quake? Scientist Susan Hough says earthquakes produce two types of waves -- a weak "P" wave and then a much stronger "S" wave. The "P" stands for "primary". And the "S" stands for "secondary". She said she thinks the "P" wave might be what set the animals off. Not all the animals behaved unusually before the quake. For example, Smith says the zoo's giant pandas didn't jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. "I'm not surprised at all," Smith said. According to Brandie Smith, _ . | [

mmlu_train_43506 | While most travelers aim to stay out of the hospital while on vacation, a growing number of medical tourists-people who combine treatment with travel - are crossing international borders for the purpose of getting medical services, which can range from a hip replacement to a tummy tuck. Widespread air travel, increasing healthcare costs in developed countries, long waiting lists and an ageing world population have all contributed to a global increase in medical tourism in the past decade. And Asia takes the lead in terms of world market share. More than 89% of medical tourists travelled to Thailand, India or Singapore in 2010, with Bangkok and Singapore leading the pack. But the cost of hotel rooms and treatment are both far more expensive in Singapore than in the Thai capital, making Bangkok the most popular place for medical tourism in the world. Even after the serious floods of 2011, 19 million tourists visited Thailand in 2011, a 20% jump from 2010, with about 500,000 tourists travelling specifically for medical treatment. Given Thailand's reputation for outstanding service, it is not hard to see why Bangkok has quickly become the medical tourism centre of Asia. The Tourism Authority of Thailand(TAT), which began medical tourism in 2004, has a detailed medical tourism website that lists many of the most popular treatments available, including dental work, dermatology and cosmetic surgery, as well as listing reputed hospitals, making it easy for potential visitors to decide on a procedure. TAT has also recently partnered with Krungthai Bank, the national bank of Thailand, to offer tourists a card called the Miracle Thailand Card, which offers some medical and life insurance coverage in case of an accident. "The hospitals in Bangkok are some of the highest quality in the world,meeting US standards,"said Steven Lash, CEO of a US-based medical travel company that sends tourists to Bangkok as well as to seven other countries, including Turkey and Mexico.

mmlu_train_78071 | The animal kingdom has a new member. On September 12, 2012, researchers made a report to the world that they discovered a new species of monkey. It is called the lesula. And it is only the second monkey species discovered in 28 years. Scientists first saw the lesula in June, 2007 in Congo, a country in Africa. The lesula lives in the rain forests. The monkey was first found as a pet in a local family. When researchers found it, the family told them that they caught the monkey in the wild and then kept it as a pet. The scientists have compared the lesula to the owl-faced monkey. The owl-faced monkey gets its name for having a long nose and a face that looks like an owl . The lesula and the owl-faced monkey are similar in size and both have a stripe on their nose. This shows the lesula and the owl-faced monkeys are close relatives, but different species. Scientists say the lesula usually weighs about twelve pounds. It has long blond hair. It eats like a vegetarian . Scientists say it is important to protect African rain forests because there may be other new species like lesula to be discovered in the future.

mmlu_train_83173 | My interest in Chinese food started many years ago, when I had my first job. I was a young reporter for the Daily Journal in San Francisco. Our office wasn't far from Chinatown. I usually managed to arrange my time so that I could go there at least two or three times a week for a good meal. The first time I ever ate Chinese food I loved it. And since then, it just tastes better and better to me. The first thing I noticed was the fresh tastes of the meat and vegetable. When I learned more about the food, I began to understand why it has this special feature. About 5000 years ago, China lost much of its wood because of over population and poor management of its forest. This loss was very bad for the country, of course, but it turned out to be very good for the food. Wood became very expensive and hard to get, so the Chinese had to learn how to use it better. In order to use less wood in cooking, they started to cut their meat and vegetables into small pieces before they put them in the hot oil. That way, the food cooked faster and they saved their _ . The food prepared in this manner kept its fresh flavor --and it's this flavor that attracts people to the art of Chinese cooking. I often wonder if the Chinese appreciated their solution to that ancient energy problem as much as I do now -whenever I eat Chinese food.

mmlu_train_62105 | Most students try to learn English grammar using grammar textbooks. They study grammar rules and take grammar tests. They use an analytical approach, attempting to memorize, and then apply, a great number of rules. However, research has proved this method inefficient and ineffective. The truth is, the human brain simply cannot consciously remember process and use hundreds of or thousands of grammar rules. Real speech is too fast. Native speakers do not learn grammar in this way, but rather intuitively and unconsciously. They learn in a complete way, not by attempting to memorize individual grammar rules. As a result, native speakers use correct grammar fluently and easily. Fortunately, it is possible for English learners to learn grammar this way. Language teacher Blaine Ray has developed a unique "intuitive" approach to teach English grammar. Her system uses "point of view" stories to teach the patterns of English grammar, allowing students unconsciously to acquire correct grammar without ever studying grammar rules. In this system, the teacher first tells a simple story from one point of view. It may be told about the past, then repeated, but beginning with "since he was a child"; then repeated again, but this time about the future. Listening to these stories allows students intuitively and effortlessly to learn English grammar and makes them be able to use it correctly when they speak. Point of View Stories is a creative new way to study English grammar, and offers hope to millions of frustrated English learners. Why shouldn't the English learners use an analytical approach? | [

mmlu_train_6948 | Coffee is one of the most popular drinks throughout the world today. In fact, according to some estimates, over 30% of all adults in the world drink coffee at least once a day on the average. Coffee contains a kind of drug called caffeine. Caffeine is a chemical that stimulates the nerves of the body. Drinking coffee tends to make people a little bit more awake--at least for a short time--because of this stimulating effect on the nervous system. A cup of coffee has, on the average, about 3% caffeine in it. One story of the discovery of the coffee plant relates to this effect of caffeine. According to the story, coffee was discovered in East Africa. The story says that coffee was first found by a goat farmer named Kaldi. This was about the year 850. Kaldi was leading his animals through the mountains and the goats were stopping repeatedly to eat the plants near the path. Suddenly, some of the goats started jumping up and down in a very strange way. Kaldi figured out that the goats were acting this way because of the plants they were eating. Kaldi himself tried eating some of the green beans that the goats had been eating. He, too, felt the stimulating effect of the beans. Kaldi wanted to prove what had happened, so he picked some of the beans and took them back to the village, where he told his story. The green bean got the name "Kaffa" and later "coffee" because the beans were discovered in a place called Kaffa in Africa. Then for years, people used to eat a few of the green Kaffa beans when they were in the mountains and needed extra energy to do their work. It was later found that the coffee beans could be picked and then dried until they turned brown, and then they could be stored. If the beans were dried and stored, they could be used at any time.

mmlu_train_41277 | People diet to look more attractive.Fish diet to avoid being beaten up,thrown out of their social group,and getting eaten as a result.That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists. The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors."In studying gobies we noticed that only the largest two individuals,a male and female,had breeding rights within the group," explains Marian Wong."All other group members are nonbreeding females,each being 5-10% smaller than its next largest competitor.We wanted to find out how they maintain this precise size separation." The reason for the size difference was easy to see.Once a subordinate fish grows to within 5-10% of the size of its larger competitor,it causes a fight which usually ends in the smaller goby being driven away from the group.More often than not, _ is then eaten up. It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish.Whether they did so voluntarily,by restraining how much they ate,was not clear.The research team decided to do an experiment.They tried to fatten up some of the subordinate gobies to see what happened.To their surprise,the gobies simply refused the extra food they were offered,clearly preferring to remain small and avoid fights,over having a feast. The discovery challenges the traditional scientific view of how boss individuals keep their position in a group.Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves,so keeping their competitors small. While the habits of gobies may seem a little mysterious,Dr.Wong explains that understanding the relationships between boss and subordinate animals is important to understand how hierarchical societies remain stable. The research has proved the fact that voluntary dieting is a habit far from exclusive to humans."As yet,we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature," the researchers comment."Data on human dieting suggests that,while humans generally diet to improve health or increase attractiveness,rarely does it improve long-term health and males regularly prefer females that are fatter than the females' own ideal."

mmlu_train_60369 | For good health, be sure to eat fruits and vegetables, exercise regularly and lie as seldom as possible. A researcher is hoping this advice will someday take hold, based on results of a "science of honesty" study she completed. Half of 110 participants were told to stop telling major or minor ("white") lies for 10 weeks, while the other half (the control group) was given no special instructions about lying. The 110 people ranged from ages 18 to 71 and came from both sexes and all income levels. All came to a laboratory each week to complete health and relationship questionnaires and to take a test showing the number of major and minor lies they had told that week. When those in the no-lie group told three fewer white lies than in other weeks, they complained less of headaches, tenseness, anxiety and other problems than those in the control group. In addition, they reported that their close personal relationships had improved and their social interactions had gone more smoothly. "The link was that clear," said study author Anita Kelly, a professor of psychology at the University of Notre Dame, Indiana. "Lying less was clearly associated with better health for those people." Previous research indicates that Americans average 11 lies per week, from the little white lies to save face or falsely praise others to major lies about serious matters. Kelly said her study differs from former studies because it didn't focus on how to detect a liar, but on the potential health consequences of telling lies. "People might recognize the more harmful effect lying can have on relationships, but probably don't recognize the extent to which it can cause a lot of stress," said Dr. Bryan Bruno at Lenox Hill Hospital in New York City. At the end of the study, some participants had created smart ways to avoid lying. Kelly noted that some realized they could simply tell the truth about their daily achievements rather than exaggerate , while others responded to a troubling question with another question to take the person's attention away. They also stopped making false excuses for running late or failing to finish tasks. "People usually think white lies are acceptable. In fact, white lies are trouble, not just major lies," Kelly said. "As long as you like, you can find effective ways to avoid lying in many cases. It depends on you." "But the goal doesn't have to be the absolute absence of lies ... the goal would be a reduction in lies," she added. Which of the following is TRUE about the research? | [

mmlu_train_7945 | Pregnancy and childbirth kill more than 536,000 women a year. More than half of the cases happened in Africa, according to the World Health Organization. In fact, most of the deaths are preventable with basic medical care. The five leading causes are bleeding, infection, high blood pressure, longtime labor and bad abortions . Mothers' deaths from such causes were largely reduced nearly a century ago in developed countries. Experts say that what kill many women are "the three delays"-- the woman's delay in deciding to go to the hospital, the time she loses traveling there and the hospital's delay in starting treatment. Only about 15 percent of births have dangerous complications . Women lack education and information about birth control. Husbands and inlaws, may decide where a woman gives birth and insist that she stay at home to save money. However, there is no single solution to a problem with so many factors--shortages of doctors, nurses, drugs, equipment, roads and transportation--though hospital officials are trying many things now. One _ measure to solve the problem for the present has been to train assistant medical officers, to perform certain operations. Some African countries are now struggling to train more assistants and midwives , and provide places for pregnant women to stay near hospitals. But there is a long way to go. Only 20 percent of women in the continent give birth at the hospital. More than 50 percent stay at home to give birth, and the rest go to local clinics that cannot handle emergencies.

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