mmlu_train_17902 | Six volunteers are about to find out what it would be like to live on Mars without ever leaving the Earth. Three men and three women will spend eight months living in a special place on the side of a volcano in Hawaii. They are part of an experiment that is designed to mimic life on Mars. Their mission began on October 15, 2014. NASA says it could send astronauts to Mars as early as the 2030s. The mission would take more than two years, so NASA needs to know how people would react to living in a small group, isolated from the rest of the world, for such a long time. Some people may become depressed or bored living under those conditions. By studying people living in similar conditions here on Eares NASA hopes to learn how to choose the most suitable people for a space mission, and how to help them get along. They will live in a two-story building. The ground floor is about 86 square meters, roughly the size of a small two-bedroom apartment. It includes shared areas like kitchen, dining room, bathroom, laboratory and an exercise room. The upstairs is less than half the size of the downstairs. It contains another bathroom and six small bedrooms. The building is located in an abandoned quarry about 2,400 meters up the side of Mauna Loa, the second biggest volcano in the world. It is constantly monitored for signs of volcanic activity. NASA chose the location because the appearance looks very similar to Mars. To make it more like being on Mars in the future, they are only able to communicate by email during the experiment. Meanwhile, there will be a 20-minute delay between the time when a message is sent and that when it is received. When they go outside, they will have to suit up in full spacesuits, just as if they were on Mars. The commander is Martha Lenio, a 34-year-old Canadian. During the mission, she will run experiments on growing food. The other members have backgrounds in physics and so on. None of them are astronauts. Mauna Loa was chosen as the experimental site because _ . | [

mmlu_train_51578 | A hospital has been forced to ban Pokemon Go players from the site after a monster hub was found in the A&E department. Royal Stoke University Hospital discovered that its casualty unit is on the same spot as a Pokemon Go 'gym' ---- where players can train their newly caught Nintendo creatures. The University Hospitals of North Midlands Trust agreed last week that patients can play Pokemon Go on wards because walking around is healthy. But the Trust has been forced to post a warning on its website about public access to A&E. It said if Pokemon Go becomes a major annoyance it would ask Nintendo---- which decides on the locations of the virtual gyms according using GPS----to have it removed from the premises . Kevin Parker, associate chief nurse, said, "Members of the public who do not need to be at Royal Stoke should not attempt to enter A&E or any other part of the hospital building to play the game. The A&E department is incredibly busy this summer. We want the public to understand that anybody who visits the hospital solely to play the game will provide an unwanted distraction to the important work of the hospital. I'm also aware of various reports in the media of unsafe areas that the game has been played in." "Royal Stoke University Hospital is a safe area where gamers can enjoy Pokemon Go." Michelle Harris, the Trust's manager, said the game could still be played by those already in hospital. "We recognize that the Pokemon Go game encourages walking and exercise, which is something that the Trust is equally keen to promote," she said. There are a number of "walking routes" established throughout the Trust that can be used to combine walking and playing the game. "Walking just 30 minutes, five times a week, can help reduce the risk of preventable illnesses such as obesity, diabetes, and heart disease." There have been several warnings about the game since its UK release. Last week a group of teenagers in Wiltshire were left stranded almost 100ft underground after they got carried away searching for Pokemon Go characters. The four boys, aged 16 and 17, ended up getting lost and had to wait to get a phone signal before they could call for help. Eventually, they contacted Dorset and Wiltshire Fire and Rescue team, who took them to safety. Damien Bence, of the fire and rescue team, said: "Pokemon Go is obviously leading people into dangerous situations." The A&E department is incredibly busy because _ . | [

mmlu_train_60022 | When you travel in South America, you'd better pay attention to the following three kinds of dangerous South American animals. Piranhas Although only a small number of piranhas are considered to be dangerous to humans, the red-bellied piranha is definitely one of those. Evidence has shown that a large group of piranhas can absolutely eat a herd of large animals crossing the river, leaving only bones. This fish lives in the freshwater streams of South America, and they can smell the blood from far away and launch attacks swiftly. It is said that they are only dangerous to humans if the water volumes are less and lower. Anacondas This South American monster of a creature often appears in the films or your nightmares!They have weighed over 230 kilograms. It is often considered to be the biggest snake in the world. You certainly don't want to get caught alone with this snake due to its method of attacking and killing its victim. It is indeed a remarkably different brand of snake type as it regularly coils around all over its target, increasing the pressure until eventually its victim dies. Its jaws are powered by large muscles that produce enough power for its over 100 sharp teeth to pass through the thick skin of an crocodile. They don't have poison. Sometimes they prefer to camouflage themselves so they look like their surroundings and swiftly draw back when humans are near. Golden Poisonous Frogs The golden poison frog might be the most-deadly of the South American animal, which is protected by means of poison. This very small frog, less than 55 mm in length, packs enough punch to take down a pair of African bull elephants. This apparently harmless frog has always been known to have killed people who have touched it directly. It's also been noted that chicken and dogs have died by contacting things on which a golden poison frog had wandered! In intense colors, they normally look attractive to their targets. What can we learn about piranhas from the passage? | [

mmlu_train_84566 | In 1938, a fishing boat off the coast of Africa pulled up its nets. One net held a very strange fish, five feet long and bright blue. Strangest of all, it had fins that looked like legs! In the nets, only this fish stayed alive for several hours. Before the fish began to rot ( ), a young woman made a drawing of it. She sent her drawing to a scientist on sea life, Professor J. B. Smith. Upon seeing her drawing of the fish, Smith couldn't believe his eyes. Could it be true? It just didn't seem possible, but there it was. It could be only one thing, a coelacanth, a fish people believe having died out fifty million years ago. How could the fish be swimming about only a few days before? If we found one, there must be others. The professor put up posters offering a reward for catching such a fish. Other scientists laughed at Smith. They thought the search was a waste of time. Years passed. It seemed the other scientists were right. But Smith never gave up hope. One day, fourteen years later, the professor received a telegram. Afish had been caught that looked like the one in the poster. Would the scientist fly to the region and check the fish? Smith did. With shaking fingers the professor raised the cloth around the fish. It was exactly like the one in the young woman's drawing. It was a coelacanth,a missing link with the past! After the discovery of the coelacanth, scientists began to wonder. Is it possible that an even stranger creature will someday be discovered?

mmlu_train_77397 | Today, people want to keep healthy through sports and exercise. But some of them have some wrong ideas about it. "A plate of chicken is a good meal before games because it has much energy." In fact, the best meal before games should have carbohydrates . Food like potatoes, bread, bananas are rich (......) in it, but chicken and meat are not. "The best time to exercise is early in the morning." No. Morning is a good time to exercise, but it may not be suitable for you. If an afternoon or evening period is suitable for you, and you enjoy the feeling of getting healthier, you can choose any time to exercise. So there is no _ time for you to exercise. "If you drink water when you exercise, you'll feel tired." The fact is that you must have some water during breaks when you exercise. And after exercising, you must have enough water.

mmlu_train_45220 | Finally, there is some good news for older dads. A new study shows that their children and even grandchildren may get a health benefit because of their older age. It's based on research into something called telomeres--tips on the ends of chromosomes Some previous studies have connected having longer telomeres with better health and longer lives. Telomeres haven't been proven to cause those benefits in the general population, but a number of researchers think they may hold secrets for things like longevity and cancer. As you age, telomeres shorten. However, previous studies have shown that the older a man is when he becomes a father, the longer the telomeres his children tend to have. The new research confirms that and finds it's extended to the grandchildren. That's a cheerier result for older dads than some other studies in recent years that indicate their kids are at higher risk for things like autism Carol Greider of Johns Hopkins University, who shared a Nobel Prize in 2009 for telomere research but didn't participate in the new study, said it's no surprise that the telomere effect would extend beyond children to grandchildren. She also said that since older fathers also tend to pass more potentially harmful genetic mutations , it's "not at all clear" whether advanced paternal age gives an overall health benefit to children. In a statement, the researchers who conducted the study said their study shouldn't be taken as a recommendation that men reproduce at older ages because there's a risk of genetic mutations. Some previous studies of the impact of older fatherhood have been less encouraging. In 2010, for example, at least two big studies confirmed a link to having children with autism. In 2008, a big Swedish study strengthened evidence linking bipolar disorder to older paternal ages. According to the latest study, we know that the older dads are likely to _ . | [

mmlu_train_58135 | If you're training for a marathon, a proper plan for water intake is important. Of course, there's the risk of dehydration . But athletes now know they can also get into trouble by drinking too much. Too much water intake can lower levels of sodium in the blood. The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research. Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight. One technique for deciding how much water you need is to get the exact numbers. Runners have to weigh themselves before and after a run to determine how much water they've lost. If their weight drops by more than 2 percent, they have not drunk enough water. Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can't get their rings off, and then they might feel sick. They may not remember where they are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration, the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water. Why do runners have to weigh themselves before and after a run? | [

mmlu_train_46133 | Steve Jobs, Apple's chief executive, made his first public appearance since going on medical leave six weeks ago, taking the stage at a San Francisco media event to introduce the iPad 2, the second generation of the company's tablet computer. Thin but energetic, Mr. Jobs showed off a thinner iPad. " We've been working on this product for a while and I just didn't want to miss this day," he said. His absence has concerned investors, especially since the group has given no details of his condition. He was diagnosed with cancer in 2004 and had a liver transplant during almost six moths of medical leave in 2009. People close to him said last month his health had been changing. Apple's stock rose more than 2 percent in the minutes after Mr. Jobs began speaking, then gave up some of its gain as he detailed the iPad 2. The iPad 2 will go on sale in black and white versions in the US on March 11 and in 26 other countries, including the UK and Germany, on March 25. The table is Apple's biggest product launch since the iPhone three years ago, and is comparable to the iPhone as the most expected in Apple's history. Most of the improvements in the latest version had been expected, including front and rear-facing video, which allows video conferencing between iPads, Mac computers and the most recent iPhones and iPods, a larger speaker, a faster processor and other upgrades. The iPad 2 is one-third thinner than the original tablet and slightly lighter, with a 9.7-inch touchscreen. It can run movies, books, games and a complete range of applications. In the US it will work with AT&T and Verizon, the top two mobile carriers. The pricing will be the same to the 2010 iPad at its introduction, ranging from $499 to $829 in six models. But Apple dropped prices on the older iPad on Wednesday by $100 across the board. Apple has made the most of its year-long head start in tablets, selling 15,000,000 units of the older iPad last year and taking about 85 percent of the market. Forrester predicted that the iPad 2 would clain 80 percent of the US market this year, or 20,000,000 out of 24,000,000 total shipped. This prediction was based on both the technical improvements to the iPad 2, and the distribution difficulties and higher prices for Apple's rivals. Motorola, BlackBerry maker Research in Motion, Samsung and others have brought out competing tablets, many based on Google's Android software. Mr. Jobs said the rest of the field was still catching up with the first iPad and their markets for applications designed for tablets had, at best, 100 small programs. This compares with 65,000 on Apple's applications store. What is the best title for the text? | [

mmlu_train_51160 | The poorer mental function seen among alcoholics, many of whom also regularly smoke cigarettes, may be partly caused by the long-term effects of nicotine , new study suggests. "People who are also smokers are more dangerous," Dr. Jennifer M. Glass, of the University of Michigan's Addiction Research Center, said. In her study, "cigarette smoking had bad effects on IQ and thinking," she said. This finding may seem wrong because many smokers feel better after smoking. Studies show that up to 87 percent of alcoholics smoke cigarettes. Yet, few studies have looked into cigarette smoking as a reason that might explain the cognitive deficits reported among alcoholics. To find out that connection, Glass and her partners examined brain function among 172 men from the same community, including 103 men who are alcoholics. The team found that heavy smokers and those alcoholics both had lower IQ scores. In the further study, the experts found that smoking also appeared to be connected with weaker verbal and visual-spatial reasoning . So, though smoking did not account for all of the poorer mental function among the alcoholics, it did seem to account for some of the effects, the report shows.

mmlu_train_52973 | Albert Hofmann was a Swiss Scientist who was fascinated by nature. This led him to a career in chemistry in which he sought answers to his uncertainties. He worked at Sandoz Laboratories where he nurtured his research work, and there he made a lot of success by working with various plants and changing them into something useful. He became famous when he became the first person to produce lysergic acid diethylamide (LSD) . In addition, he was also the first person to taste it and learn about its hallucinogenic effects. He was deeply connected to the nature and argued that LSD, besides being useful for psychiatry , could also be used to promote awareness of mankind's place in nature. However, he was disappointed that his discovery was being carelessly used as a drug for entertainment. Because of his discovery, LSD fans have fondly called him "The father of LSD". Besides carrying out his scientific experiments, he also authored numerous books and more than 100 scientific articles. In 2007, he featured in a list of the 100 greatest living geniuses , published by The Telegraph Newspaper. Childhood & Early Life Albert Hofmann was born in Baden, Switzerland, on January 11, 1906. He was the eldest of four children. His father was a poor toolmaker in a factory and they lived in a rented apartment. He spent much of his childhood outdoors, and grew up with a very deep connection with nature. He had mind-blowing experiences in childhood, wherein nature was changed in magical ways that he didn't understand. These experiences caused questions in his mind, and chemistry was the scientific field which allowed him to understand them.

mmlu_train_69244 | Who hasn't enjoyed eating peanuts? Did you know that although peanuts look like nuts and taste like nuts, they aren't nuts at all? They belong to the pea family, so they are called peanuts. The peanut grows flowers above ground, but its "fruit" grows underground. It grows in more countries than most other "nuts". The peanut is a native South American plant. Scientists believe that it grew wild in Brazil long ago. They think that for several thousand years the early peoples of South America made it a part of their diet. These peoples were nomads who moved on when a natural food could no longer be found in one area. Along the way they probably let fall some peanuts, which got into the ground and grew. This is believed to be the way the plant reached the place where the Incas lived. The Incas, from about 1100 to 1532, thought highly of peanuts. The peanuts were eaten in several forms and used as sacrificial offerings to the Incan Sun God. Later in the 16thcentury, European soldiers had brought peanuts to other parts of the world, including North America, Africa, Asia, Europe, and Pacific Islands. Although peanuts were found native in South America, they are now grown in almost every country that has warm weather. India produces the most peanuts. China's production is next, followed by the United States. The peanut is special in more ways than one. It can be eaten raw, boiled, roasted, or fried. Hundreds of widely different products have been made from it. Carver, an American scientist, set himself the task of discovering new uses for eating and for many other products. Peanuts are very highly _ and are also high in protein . Americans use about seven-tenths of their protein in the form of meat. In India, where the poor can't pay for meat or milk, peanut meal and peanut milk have been produced. These have been a great help to the poor. New products are continually being made from peanuts, among them peanut cheese and a powder that becomes peanut butter when water is added. The fact is that peanuts are so healthy that they were used by astronauts. The unusual nut that isn't a nut is one of nature's most amazing gifts. What is the purpose of the article? | [

mmlu_train_10084 | Birds that are half-asleep -- with one brain hemisphere alert and the other sleeping -- control which side of the brain remains awake, according to a new study of sleeping ducks. Earlier studies have recorded half-brain sleep in a wide range of birds. The brain hemispheres take turns sinking into the sleep stage characterized by slow brain waves. The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere's eye stays open and alert. Birds also can sleep with both hemispheres resting at once. Decades of studies of bird groups led researchers to predict extra alertness in the end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds tended to watch carefully on the side away from their companions. Ducks in the inner spots showed no preference for gaze direction. Also, birds napping at the end of the line depend on single-hemisphere sleep, rather than total relaxation, more often than inner ducks did. Turning 16 birds through the positions in a four-duck row, the researchers found that compared with 12 percent for birds in inner spots, outer birds half-asleep during some 32 percent of napping time. "We believe this is the first evidence for an animal behaviorally controlling sleep and wakefulness at the same time in different regions of the brain," the researchers say. The results provide the best evidence for a long-standing assumption that single-hemisphere sleep developed over time as creatures scanned for enemies. The preference for opening an eye on the lookout side could be widespread, he predicts. He's seen it in a pair of birds napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror-side eye closed as if the reflection were a companion and the other eye stayed open. Useful as half-sleeping might be, it's only been found in birds and such water animals as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a sleeping animal to surface occasionally to avoid drowning. Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA says he wonders if birds' half-brain sleep "is just the tip of the iceberg." He supposes that more examples may turn up when we take a closer look at other species.

mmlu_train_57575 | The "melting pot" in American cuisine(. ) is a myth, not terribly unlike the idea of a melting pot of American culture, notes chef Dan Barber. "Most cultures don't think about their cuisine in such monolithic terms," he says. "French, Mexican, Chinese, and Italian cuisines each consist of dozens of distinct regional foods. And I think 'American' cuisine is moving in the same direction, becoming more localized, not globalized. " American cuisine is shaped by the natural wealth of the country. Having never faced agricultural hardship, Americans don't have to rely on rotating crops, such as the Japanese, whose food culture now showcases buckwheat alongside rice, or the Indians, or the French and Italians, who feature beans alongside wheat. "That kind of negotiation with the land forced people to incorporate those crops in to the culture," says Barber. And so eating soba noodles becomes part of what it means to be Japanese, and eating beans becomes part of what it means to be French. So if what we eat is what we are, what are Americans? Well, meat. "If Americans have any unifying food identity, I would say we are a mostly white meat culture," says Barber. "The protein-centric dinner plate, whether you're talking about a boneless chicken breast, or a 16-ounce steak, as an everyday expectation is something that America really created, and now exports to the rest of the world." Every single culture and religion uses food as part of their celebrations, says Ellen Gustafson, co-founder of the FEED Project and The 30 Project, which aims to deal with both hunger and overweight issues globally. "The celebratory nature of food is universal. Every season, every harvest, and every holiday has its own food, and this is true in America as well. It helps define us."

Not sleeping enough can also make it harder to think clearly the next day. Sleep experts have long known that getting a good night's sleep is important. It helps kids perform their best during the day. A recent study shows that sleep helps improve problem--- solving skills and creative thinking. For the study, two groups of volunteers answered a math problem. The group that slept for eight hours solved the problem correctly more often than the group that did not get enough sleep. While you sleep, your brain is busy doing its "homework". It sorts out information from your day. Getting enough sleep each night can _ your brainpower. That will help you do your best in school.

mmlu_train_28941 | Holding a cell phone against your ear or storing it in your pocket may be dangerous to your health. This explains a warning that cell phone manufacturers include in the small print that is often ignored when a new phone is purchased. Apple, for example, doesn't want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry's manufacturer, recommends 2.5 centimeters. If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion minutes annually - earn $109 billion for the wireless carriers. Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled. Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population. "Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer. Children are more _ to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid . No studies have yet been completed on cell phone radiation and children, she says. Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains. Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen .

mmlu_train_47135 | Cloning is suggested as a means of bringing back a relative, usually a child, killed tragically. Some parents can understand that wish, but it must first be recognized that the copy would be a new baby and not the lost child. Here lies the difficulty, for the sad parents are seeking not a new baby but a return of the dead one. Since the original would be fondly remembered as having particular talents and interests, would not the parents expect the copy to be the same? It is possible, however, that the copy would develop quite differently. Is it fair for the new child to be placed in a family with such unnatural expectations? Copying is also suggested as a means by which parents can have the child of their dreams. Couples might choose to have a copy of a film star, baseball player or scientist, depending on their interest. But because personality is only partly the result of genetic inheritance , conflicts would be sure to come up if the cloned child failed to develop the same interests as the original. What if the copy of Einstein shows no interest in science? Or the baseball player turns to acting? Success also depends upon fortune. What if the child does not live up to the hopes and dreams of the parents simply because of bad luck? Every baby should be wanted for itself, as an individual. In making a copy of oneself or some famous person, a parent is carefully specifying the way he or she wishes that child to develop. In recent years, particularly in the United States, much importance has been placed on the right of individuals to reproduce in ways that they wish. So I suggest there is a greater need to consider the interest of the child and to refuse these suggested uses of cloning. According to the author, in cloning a lost child parents _ . | [

mmlu_train_24576 | When a big exam is coming up, you probably feel anxious about any wasted time and want to begin school as soon as you probably can. But tens of thousands of British high school students will soon be getting up later. They're taking part in a new experiment by Oxford University to see if later classes can improve their exam results. Grades 10 students in the UK have to take the nationwide General Certificate of Secondary Education (GCSE) exams. They have to pass these exams in order to study more advanced courses, and later apply for universities. The Oxford University project means that GCSE students from more than 100 schools across England will start school at 10 am, more than one hour later than the current start time (8:50 am). The project is based on scientific evidence that teenagers are "out of sync " with traditional school hours, the Telegraph reported. And what they need is more sleep in the morning. "We know that something funny happens when you're a teenager, in that you seem to be out of sync with the world," said professor Colin Epsie, who is leading the study. "Your parents think it's because you are lazy and opinionated and everything will be OK if you could get to sleep earlier. But science is telling us that teenagers need to sleep more in the mornings." Everyone follows a natural cycle of sleep and wakefulne ss. Biology has decided that teenagers go to sleep around midnight and don't feel fully awake until 9-10 am, according to scientists. That's two hours later than adults. And their body clocks stay like this until the age of around 21 for males, and 19 for females. "Society provides school for learning, but the brain provides sleep. So we are exploring the possibility that if you delay the schools start time until 10 am, that will improve learning performance," said Epsie. The results could be positive, based on previous studies. An early study at the UK's Monkseaton High School in 2009 found that starting an hour later improved grades in core subjects by 19 percent. The Oxford project is expecting to publish the results in 2018. It's time to wait and see whether scientists will give us an excuse to get up late. What's the best title of the article ? | [

mmlu_train_71203 | After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered a planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid water. Scientists think there is a chance that the planet could have life. The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion kilometres -500 million times farther away from us than the moon. A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can't live that long, but robotic explorers could make the job easier. However, our fastest spacec raft don't come anywhere near that one-tenth light-speed mark. At present, scientists don't know what the surface might be like on Gliese 581g. What they know is that the planet is at the right distance from its star to have liquid water. It's also at the right distance to have an atmosphere that could protect the water if it is on the surface. Although spacecraft won't be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes towards the planet and search for radiation . By studying the radiation, scientists would find out about the chemicals around the planet and discover if Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea whether the planet has life or not. But it'll probably be many years before we can do this properly. People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.

mmlu_train_46528 | Farm-raised pigs are dirty, smelly animals that get no respect. They're also an environmental hazard. Their manure contains phosphorus ,which, when it rains, runs off into lakes and rivers, consuming oxygen, killing fish, stimulating algae overgrowth and emitting greenhouse gases. Doing away with the pig is not an option. Pigs provide more dietary protein, more cheaply, to more people than any other animal. Northern Europe still maintains the highest pig-to-human ratio in the world (2-1 in Denmark), but East Asia is catching up. During the 1990s, pork production doubled in Vietnam and grew by 70 percent in China--along densely populated coastlines, pig density exceeds 100 animals per square kilometer. The resulting pollution is "threatening fragile coastal marine habitats including mangroves ,coral reefs and sea grasses ,"according to a report released in February by the Food and Agriculture Organization of the United Nations. As it turns out, there is a solution to the pig problem, but it requires a change of mind-set among environmentalists and the public. Two Canadian scientists have created a pig whose manure doesn't contain very much phosphorus at all. If this variety of pig were adopted widely, It could greatly reduce a major source of pollution. But the Enviropig, as they call it, is the product of genetic modification--which is anathema to many Westerners. The Enviropig is one of many new technologies that are putting environmentalists and organic-food supporters in _ : should they remain categorically opposed to genetically modified (GM)foods even at the expense of the environment? Elsewhere, trees grown for paper could be made amenable to much more efficient processing, reducing both energy usage and toxic chemical bleach in waste water from paper mills. The most significant GM applications will be ones that help lessen the problem of agriculture , which accounts for 38percent of the world's landmass and is crowding out natural ecosystems and species habitats. Chances are, farmers will continue to grow their polluting organic pork, their allergenic organic soy and their neurotoxin sprayed organic apples. Worse still, they will make sure that no one else gets a choice in the matter of improving the conditions of life on earth--unless, that is, others rise up and demand an alternative.

The scientists say that the human body has changed very little since human first appeared on earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times. So they are called "diseases of civilization". Many cancers and diseases of the blood system, including heart attacks and strokes are examples of such diseases. Scientists noted that early stone-age people used very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and life today. Stone-age people hunted wild animals for their meat, which had much less fat than farm animals. They also ate a lot of fresh wild vegetables, and fruits. They did not use milk and other dairy products, and they made very little use of grains. But today, we eat a large amount of dairy products and grain foods. We eat six times more salt than stone-age people. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C. People today probably do not want to live as people thousands of years ago did, but scientists say that we would be much healthier if we ate as those ancient people did, cutting the amount of fatty, salty and sweet foods.

mmlu_train_22895 | Have you winterized your horse yet? Even though global warming may have made our climate more mild, many animals are still hibernating .It's too bad that humans can't hibernate. In fact, as a species, we almost did. Apparently, at times in the past , peasants in France liked a semi-state of human hibernation . So writes Graham Robb, a British scholar who has studied the sleeping habits of the French peasants. As soon as the weather turned cold people all over France shut themselves away and practiced the forgotten art of doing nothing at all for months on end. In line with this, Jeff Warren, a producer at CBC Radio's The Current, tells us that the way we sleep has changed fundamentally since the invention of artificial lighting and the electric bulb. When historians began studying texts of the Middle Ages, they noticed something referred to as "first sleep", which was not clarified, though. Now scientists are telling us our ancestors most likely slept in separate periods. The business of eight hours' uninterrupted sleep is a modern invention. In the past , without the artificial light of the city to bathe in, humans went to sleep when it became dark and then woke themselves around midnight. The late night period was known as "The Watch" It was when people actually kept watch against wild animals ,although many of them simply moved around or visited family and neighbours . According to some sleep researchers, a short period of insomnia at midnight is not a disorder .It is normal . Humans can experience another state of consciousness around their sleeping, which occurs in the brief period before we fall asleep or wake ourselves in the morning .This period can be an extraordinarily creative time for some people .The impressive inventor, Thomas Edison , used this state to hit upon many of his new ideas. Playing with your sleep rhythms can be adventurous ,as anxiety may set in. Medical science doesn't help much in this case. It offers us medicines for a full night's continuous sleep, which sounds natural ; however, according to Warren's theory,it is really the opposite of what we need.

But our 21st-century lifestyle is also loud and, if we don't take notice, it can have an effect on our hearing. Most teenagers don't think about hearing loss. But if you experience any of the followingsymptoms , you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people's expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears. iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of itsmaximum volume , and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal. Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss. Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it's like working in a loud factory all day, being amaintenance person under a jet airplane or using ajackhammer on a building site. Similarly, iPod music can cause a short time orpermanent hearing damage. A loud iPod can cause aruptured eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to theauditory nerves that connect to the brain. If this happens, hearing loss becomes permanent. Which of the following shows that you are suffering hearing loss? | [

mmlu_train_86235 | Here are some easy tips for getting to sleep. They can help you deal with tension, stress and anxiety, and enjoy a good night sleep. Not every one of these tips alone will get you to sleep, but a few of them at least should be useful. Get some physical exercise during the day. Even 15 minutes a day of exercise (at least half an hour before going to bed, so your body will have a chance to slow down) will give your body the activity and oxygen it needs to help you relax more and sleep better. Listen to the light music. Play some soft, smooth music that help you sleep. Of course you must have a recorder or CD player that will automatically turn off because if you get up and turn it off in the end, it'll lose its effect. Drink warm milk. A glass of warm milk 15 minutes before going to bed will keep you calm. Keep regular bedtime hours. Your body likes regular routines ,.It likes to know that it's going to get up at the same time each day, eat at the same time, and go to bed at the same time. Keep far away from caffeine, alcohol and tobacco. Before you go to sleep, you'd better not drink coffee or cola which has caffeine. Don't drink wine, beer or champagne which has alcohol and don't smoke. Don't watch TV or read before going to bed. Wait at least half an hour before going to bed after reading or watching TV. If you choose to use the method of listening to music, the writer advises us _ . | [

mmlu_train_8979 | If you're a male and you're reading this, congratulations! You're a survivor. According to statistics,you're more than twice as likely to die of skin cancer than a woman,and nine times more likely to die of AIDS. Assuming you make it to the end of your natural term,about 78 years for men in Australia,you'll die on average five years before a woman. There're many reasons for this--typically,men take more risks than women and are more likely to drink and smoke but perhaps more importantly, men don't go to the doctor. "Men aren't seeing doctors as often as they should," says Dr. Gullotta."This is particularly so for the over-40s, when diseases tend to strike. According to a recent survey, 95%of women aged between 15 and early 49s see a doctor once a year, compared to 70%of men in the same age group. "A lot of men think they're unbeatable,"Gullotta says."They only come in when a friend drops dead on the golf course and they think, Geez, if it could happen to him ..." Then there's the ostrich approach."Some men are scared of what might be there and would rather not know," says Dr. Ross Cartmill. "Most men get their cars serviced more regularly than they service their bodies," Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups. "Prevention is cheaper in the long run than having to treat the diseases.Besides, the final cost is far greater,it's called premature death." Which of the author's statements is the most important reason that men die five years earlier on average than women according to the passage? | [

mmlu_train_39902 | You might notice something new in the next few years as you watch Disney programs: Starting in 2015, there won't be any candy, sugary cereal or fast-food commercials aimed at kids. The Walt Disney Company has become the first major media company to ban ads for junk food on its TV channels, radio stations and websites. It hopes this will stop kids from making poor food choices. First Lady Michelle Obama called it a "game changer" that is sure to send a message to the rest of the children's entertainment industry. "Just a few years ago, if you had told me or any other mom or dad in America that our kids wouldn't see a single ad for junk food while they watched their favorite cartoons on a major TV network, we wouldn't have believed you," said the First Lady, who heads a campaign to help stop child obesity. The ban would apply to Disney-owned ABC stations as well as Radio Disney and Disney-owned websites aimed at families with young children. In addition, Disney plans to make changes to its kids' menus at theme parks and resorts . Fast-food options will be replaced with healthier choices, such as smoothies , apples, vegetables and yogurt. In addition to candy bars and fast-food meals, other foods that don't meet Disney's nutritional standards will be banned from the company's kid-targeted media. Any cereal with 10 grams or more of sugar per serving will be _ . There will be no ads for full meals of more than 600 calories. Juices with high levels of sugar and foods with too much salt will also be pulled. Leslie Goodman, Disney's senior vice-president of Corporate Citizenship, said a company that wants to advertise will need to show that it offers a range of healthy options. Disney isn't the only one pushing away unhealthy foods.

mmlu_train_5611 | Red squirrels have been wiped out from a large area of northern Italy, threatening a further biodiversity crisis for the species similar to its near extinction in the British Isles. There are now no red squirrels left in an area of more than 1,150 square kilometres (sq km) in Piedmont, according to research from the universities of Turin, Genoa and Varese. On the edge of this large region, the species is also under threat from the invasions of grey squirrels. If the spread of the grey squirrel continues uncontrolled, the species could spread as far as France, the scientists fear. They are calling for more research and control and conservation measures aimed at preserving the remaining red squirrel populations and containing the spread of the greys. Grey squirrels were introduced into Italy ly recently, in 1948. They were a gift from the US ambassador and kept in Turin, but escaped into the wild and rapidly colonized the surrounding area - despite warnings from the UK, where importing grey squirrels was forbidden from before the Second World War, when the destructive effects of having imported greys in the 1880s had become clear. Grey squirrels are not only more aggressive than the native European red squirrel, which causes them to invade red-dominated areas and take over, but they also carry a deadly virus, the squirrel pox. While greys are largely immune to the virus, it is deadly to red squirrels, which typically die within one or two weeks of being infected. From only four animals in 1948, at Stupinigi near Turin, the greys spread rapidly in recent years. Until 1970 the distribution of greys was limited to the Stupinigi woods, occupying an area of about 12 sq km. By 1990 this area had expanded to more than 200 sq km, stretching mainly southwards into the Cuneo province. By 2000, grey squirrels occupied 900 sq km and this year, fresh research from the three universities shows that their distribution now extends to more than 2,000 sq km. In more than half of that area, the native reds have been entirely wiped out, and in the remainder they are under severe threat. Which of the following about red squirrels is wrong? | [

mmlu_train_11504 | Babies who watch TV are more likely to show late learning development and language at 14 months, especially if they are watching programs aimed at adults and older children, according to a new study, which would probably surprise those parents who leave their babies in front of a TV set. Babies who watched 60 minutes of TV daily had developmental scores a third lower at 14 months than babies who were watching less TV. Although their developmental scores were still in the normal range, the difference may have been due to the fact that when children and parents are watching TV, they are missing the talking, playing and other communications that are important to learning and development. This new study, which appeared in the Aechives of Pediatric and Adolescent Medicine, followed 259 lower-income families in New York, most of whom spoke Spanish as their primary language at home. Other studies of higher-income families have also come to the same conclusion: TV watching is not only non-educational, but it seems to slow down babies' development. But what about "good" TV, like Sesame Street? The researchers didn't find any difference when compared to non-educational programs designed for small children, like Spongebob SquarePants. Earlier research by some of the same scientists, most of whom are at New York University School of Medicine's Bellevue Hospital Centre, has found that parents whose children watch non-educational TV programs like Spongebob SquarePants spend less time reading to their children or teaching them. At this point, parents reading this will probably be astonished. TV is so often a parent's good friend, keeping children happily occupied so that the adults can cook dinner, answer the phone, or take a shower. But, clearly, this electronic babysitter is not an educational aid. It is best to make sure the babies are fast asleep if you have to watch TV. We can infer from the passage that _ . | [

mmlu_train_12744 | People typically wash their hands seven times a day in the United States, but they do it at a far higher temperature than is necessary to kill germs , a new study says. The energy waste is equivalent to the fuel use of a small country. Amanda R. Carrico, a research assistant professor at the Vanderbilt Institute for Energy and Environment in Tennessee, told National Geographic that hand washing is often "a case where people act in ways that they think are in their best interest, but they in fact have inaccurate beliefs or outdated perceptions." Carrico said, "It's certainly true that heat kills bacteria, but if you were going to use hot water to kill them it would have to be way too hot for you to tolerate." Carrico said that after a review of the scientific literature, her team found "no evidence that using hot water that a person could stand would have any benefit in killing bacteria." Even water as cold as 40degF (4.4degC) appeared to reduce bacteria as well as hotter water, if hands were scrubbed, rinsed and dried properly. Using hot water to wash hands is therefore unnecessary, as well as wasteful, Carrico said, particularly when it comes to the environment. According to her research, people use warm or hot water 64 percent of the time when they wash their hands. Using that number, Carrico's team calculated a significant impact on the planet. "Although the choice of water temperature during a single hand wash may appear unimportant, when multiplied by the nearly 800 billion hand washes performed by Americans each year, this practice results in more than 6 million metric tons of CO2 equivalent emissions annually," she said. The researchers published their results in the July 2013 issue of International Journal of Consumer Studies. They recommended washing with water that is at a "comfortable" temperature, which they noted may be warmer in cold months and cooler in hot ones. What can we learn from the passage? | [
"It's necessary and useful for people to wash their hands frequently every day.",
"We can wash our hands with water that is at a \"comfortable\" temperature.",

mmlu_train_53855 | All plant cells are capable of taking up water. Even dead ones do to a certain degree. Absorption of water by dead cell walls makes wood become larger. In common land plants, the living cells of roots take upmost of the water. Land plants without roots do exist, however. Those greenish-yellow lichens you see on rocks in the high mountains have no roots. Half a billion years ago, when water plants started to enter the land, the first land plants did not have roots. Even among the flowering plants, one finds rootless forms. These flowering plants are "the higher plants" because they evolved recently and are thus considered higher on the evolutionary scale . In the Peruvian desert, there grows one of these rootless higher plants, a bromeliad. It is a relative of the pineapple. Even if this plant had roots, they would be of no use, because where the plant grows, it never rains. The plant gets its water only from the dew it collects at night, when its leaves cool off. Such rootless plants, of course, can be moved with ease, but they will only grow when they are placed out in the open. If they are placed too near a house, the radiation from the heat of the house prevents the leaves from cooling and so prevents dew from forming, and the plant dies. In the southern United States and in Puerto Rico, one sees growing high above the streets on the insulation of electric wires. These plants get their water from rain, and the only soil they ever come in contact with is the dust that may blow on their leaves.

mmlu_train_16269 | Children at a school in Italy have today begun an experiment to replace all their books with personal computers. The pupils involved will each be given a special laptop that contains their entire courses. Until today, the Don Milani di Rivoli elementary school in central Turin was like any other. Children turned up, got out their books and pens and began the process of learning. But now, in what's being described as a unique experiment, 60 fifth-grade pupils and a number of third-graders, will start using computers only. The mini-laptops, which run Windows software, all have a full curriculum programmed into them. The pupils will use the computers to do all their reading and writing. Security systems within the laptops mean the children's access to the Internet is strictly controlled. The machines weigh less than a kilogram, can be dropped from a height of 1.5 metres and are waterproof. Instead of spending 700 dollars a year on books, the laptops, built by the Italian company Olidata, cost less than 400 dollars. One of the teachers involved in the scheme says that, for the first time, schools will be able to verify in a scientific way how a computer alone can improve the learning process. The experiment, which has the backing of parents, is due to last a year. In other countries, such a programme is also being carried out. Venezuela is ordering one million low cost laptops for its school children. The machines will be based on the Intel Classmate laptop that has been designed for school children.

mmlu_train_61596 | Have you ever wondered when dogs first became "man's best friend" and the world's favourite pet? If you have then you're not alone. When and where dogs first began living side-side with humans are questions that have stirred hot debate among scientists. There are a few hard facts that all agree on. These include that dogs were once wolves and they were the first animal to be domesticated by humans. They came into lives some 15000 years ago, before the dawn of agriculture. Beyond that, there is little agreement. The earliest bones found that are unquestionable dogs and not wolves date from 14,000 years ago. However, 30,000-year-old skulls have been discovered in France and Belgium that are not pure wolf and some scientists think could be dogs. With such puzzling evidence, many scientists are now turning to DNA to find out when and where dogs were first domesticated. In one research project, tens of thousands of blood samples have been taken from street dogs around the world. The plan is to compare them with those of wolves. It's even possible to analyse DNA from ancient bones. Tiny pieces of the 30,000-year-old skulls mentioned earlier are currently being studied, and another DNA study has already shown that ancient dogs preserved in the Alaskan ice-fields evolved from Asian wolves, not American ones. Indeed, the ancient DNA may turn out to be more informative than the DNA of living dogs. Because dogs have accompanied humans around the world for thousands of years, their current distribution may tell us very little of their origins. This is why different groups of scientists believe that dogs variously originated in eastern Asia, Mongolia, Siberia, Europe or Africa. But why were the animals domesticated in the first place? The most recent theory is that dogs domesticated themselves, initially living in and around our ancient villages to eat any food thrown out. Today, this is a way of life still shared by three -quarters of a billion unowned dogs worldwide. How did scientists determine the origins of the ancient dogs found in Alaska? | [

You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense. Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo . Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet . The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season. Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health.

mmlu_train_22730 | A cell phone in a vehicle can be a life-saving communication tool in case of emergency. However, actually using a cell phone while driving can be life-threatening. Studies have shown that new drivers are especially prone to have an accident when they use a cell phone while driving. The reason for this is that new drivers have less experience in concentrating on driving during distractions . Also, several studies done on teen drivers found that many teens often send text messages while driving. Since text messaging involves both the hands and the eyes, this is thought to be more distracting and dangerous than when drivers use a cell phone only for speaking and listening while driving. All drivers who use a cell phone while driving are reported to be at least four times more likely to have an accident than drivers who don't use a cell phone while driving. Such studies have inspired many countries, including the United States, to have at least some bans on hand-held cell phone use while driving. However, many people feel that these restrictions are far from enough. Hand-free cell phones were still found in many studies to distract the drivers' attention even though the drivers had both hands on the wheel . In some studies, drivers themselves admitted that they sometimes become distracted when they use any type of the cell phones while driving. Some studies have shown that using a cell phone while driving is actually just as dangerous as driving drunk! Both cases can impair the drivers' concentration as well as their reaction time to other vehicles or problems on the road. If a cell phone is used in crawling traffic such as a traffic jam, it is not as likely to cause danger as when a driver uses a cell phone at even moderate speeds on twisting and turning roads. Why are new drivers who use a cell phone while driving more likely to have an accident? | [

mmlu_train_29331 | Humans have launched themselves into the outer space. They've landed on the moon. They've built habitable space stations that orbit the Earth. The next giant leap for mankind is to reach another planet - specifically, Mars. The problem is that it's no easy task. The planet is 586 times further away from the Earth than the moon, and it'll take around 180 to 220 days to reach Mars, depending on where each planet is in its orbit. Such long periods in space have suggested many potential health problems, including hormonal changes, skin conditions, and muscle and bone deterioration . Here's where some furry friends come in. A wide range of animals have been in space, from fruit flies and spiders to cats, and dogs. Such experiments began as far back as the late 1940s in first tests to see if living things could _ the extreme g-force of a rocket launch. Mice continue to play a very important part in space experiments, mainly because the animals make excellent test subjects. They're small, which makes them inexpensive and easy to care for. In addition, their size and short life span make it possible to do the equivalent of several human years of tests in a much shorter time. Finally, because mice are mammals, they share many common characteristics with humans in terms of genetics, biology and behavior. Astromice have hit the headlines recently, as a team of scientists led by Betty Nusgens, professor of biology at the University of Liege in Belgium, found that the mice suffered a 15 percent thinning of their skin after 91 days aboard the International Space Station (ISS). This experiment was part of a wider NASA mission called the Mice Drawer System (MDS). The Italian Space Agency developed the facility, which allows six mice to be housed, monitored, and automatically fed and watered aboard the ISS, among which three survived during the mission. The mice have participated in 20 separate experiments, to study such effects as osteoporosis , anemia and heart health. Results for the 20 experiments are coming in gradually. But it's clear that mice continue to play an important role in the ongoing quest to conquer the final frontier. According to Betty Nusgens and her team, the mice aboard the ISS _ . | [
