mmlu_train_56901 | (This selection was originally published in 1992. Pluto is no longer classified as a planet.) Pluto is in many ways the strangest of the planets. It is small and has a large moon(called Charon). Its orbit is unusual, which may cause it to have seasons in the sense that when it is close to the sun, the liquid methane on its surface boils to form a kind of atmospheric haze . When the planet moves farther away from the sun, it starts to snow solid methane. Pluto is not dark. Despite its great distance from the sun, the surface of Pluto is probably as bright as a moonlit night on Earth. The reason is all that methane, which is as white as newly fallen snow. The discovery of Pluto was more accident than design. The American astronomer Percival Lowell had predicted the existence of a ninth planet(he called it Planet X)based on what he took to be irregularities in the orbit of Neptune. Today astronomers argue that these "irregularities" weren't real, but the result of instrumental error. Nevertheless, Lowell produced predictions about where Planet X ought to be(although, to be honest, the predictions changed occasionally when he redid the calculations).In any case, in 1930 Clyde Tombaugh, doing a systemic sky survey that would have found the planet no matter where it was, discovered the planet we now call Pluto. By coincidence, its position was pretty close to where Lowell's last prediction said it should be. Was it just luck? We'll never know. On Pluto's surface, liquid methane boils to form an atmospheric haze, which would be most similar to _ . | [

mmlu_train_69366 | Scientists have made the world's first human-sheep----with the body of a sheep and half-human organs . Amazing, but true. The sheep is15percent human and 85 percent sheep. The breakthrough makes it possible to use animal organs in human bodies in the future. Professor Esmail Zanjani of University of Nevada, US, has spent seven years And over $9 million on the work. Zanjani took stem cells from the human body and put them into the sheep while it was still in its mother's body. The stem cells made other cells that grew into organs. Zanjani believe that in the future such sheep might be used to help humans. Two months later a human-sheep is born, it has a liver , heart, ling and brain that are part-human. These organs could be used to help people in need of them. There are different opinions about his work, however. Some say that scientists don't have the right to create new creature . Using animal organ might bring animal viruses into human bodies. Others are afraid that the work might change sheep. But Professor Anjani has said that this is impossible.

mmlu_train_64729 | Have you ever walked outside thinking it was one temperature but quickly discovered it felt colder? That is because of the "wind chill" effect. Wind chill is how cold people and animals feel when they are outside, not the actual temperature on the thermometer . It is based on how quickly your body loses heat when it is exposed to wind and cold. When the wind is strong, your body quickly loses heat, making the temperature of your skin drop. When scientists first started calculating wind chill, they used research conducted in 1945 by explorers to Antarctica who measured how quickly water froze outside. But water freezes faster than exposed skin, so the wind chill index based on that data wasn't accurate. In 2001, the US government began to measure wind chill more precisely by testing how quickly people's skin froze. Twelve volunteers were placed in a chilled wind tunnel. Equipment was stuck to their faces to measure the heat flow from their cheeks, forehead, nose and chin while they walked three miles per hour on a treadmill . The experiment revealed how quickly exposed skin can be damaged, particularly unprotected areas like your fingers, toes, the tip of your nose and your ear lobes. In fact, 40 percent of your body heat can be lost through your head! Signs you might have frostbite are when the skin turns white or pale and you lose feeling in that area. The information collected from the volunteers helped scientists work out the math to compute wind chill. It involves wind speed and air temperature. If, for example, the temperature outside is zero degrees Fahrenheit and the wind is blowing at 15 miles per hour, the wind chill is calculated at 19 degrees below zero. At that wind chill temperature, exposed skin can freeze in 30 minutes. You can find a calculation table at www.nws.noaa.gov/om/windchill/index.shtml. Experts advise in cold weather that you wear loose-fitting, lightweight, warm clothing, worn on top of each other. Air caught between the clothes will keep you warm. The best cold-weather coats have head coverings made of woven material that keep out water. So next time the temperature drops and you want to play outside, listen to your parents when they tell you to wrap up warm! When might a person have frostbite according to the passage? | [

mmlu_train_32736 | Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives -either recorded or real-may even prevent elephants from damaging farmer's crops. In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away. Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next,Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family. From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place. Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away. We know from the passage that elephants may be frightened of _ . | [

mmlu_train_18053 | This year, Face book, the social media website announced that it would cooperate with several news organizations -- including The New York Times, The Guardian, and the BBC -- to place news stories directly into users' personal Face book webpage. Stories published using Face book Instant will load more quickly and keep the style of the original publisher, who will keep all the advertising income the stories earn -- at least for now. The deal shows how important social media has become to news organizations, and is a clear sign of how the world of news is changing -- and has been for a while. Many thought of it as the death of the newspaper, when Google News began in 2002. It had no human editor. Instead Google used, and still uses, a secret computer program that selects and displays news stories according to the reader's personal interests, More recently, Associated Press and Yahoo have been publishing computer-written articles. Both use special software to automatically produce stories about company financial results and sports reports -- areas where the quality of writing is felt to be of secondary importance to the accuracy of the data. I think we should be concerned about such developments. One concern is that Facebook, Google and other social media websites see journalism as a sideline , a way of putting people in front of advertisements. _ isn't their primary function -- so if it stops making them lots of money, they're likely to stop doing it. There's another concern that computer-written articles are not actually journalism at all, because what a human news team produces is actually quite complex. A well-written news story puts information in context, offers a voice to each side of an argument and brings the public new knowledge. Although economics and speed of delivery mean readers will probably choose a computer-written story over a carefully shaped article -- at least for daily news -- I don't think the computers will be writing any in-depth articles for a while yet. Computer-written news reports have so far focused on sports and finance because _ . | [

mmlu_train_66342 | Do you always forget where you placed your keys or your purse? What was the name of the movie you saw last week? The major cause of your forgetfulness may be linked to what you store in your body, not in your short-term memory bank. Tests continue to show that people with enough Vitamin B-2 do well in memory exams. The "B" could stand for "brain", if you're one of many with limited instant recall. And the number one source of that vitamin is sunflower seeds. Even when you're sleeping or relaxing, your brain is still at work. Although it makes up just two percent of your total body weight, it uses up to 30 % of the calories you take in each day. For it to work properly, it must be fed. Even if you're not a breakfast eater, that meal is the best way to prepare your brain for the day. A quick and easy English _ with peanut and butter in it, a glass of milk, and an orange, might be what your brain may be asking you the first thing in the morning when you feel your head is in a fog. Having sunflower seeds and fruit between meals adds more muscle to that hungry, demanding organ. Vitamin B-1 also helps the memory, and that is found in eggs, meats and nuts. In Chinese culture, walnuts are known as the fruit for a long life because it is believed that they feed both the kidneys and the brain. And according to Chinese culture, if you keep those two important organs in good working order, you'll live longer.

Mrs.Obama said that the campaign was designed to encourage people to live healthier lives,but admitted that she herself was not immune to the temptations of junk food. "I love burgers and fries.And I love ice cream and cake.And so do most kids," she said.But,she added,"We're not talking about a lifestyle that excludes all that." "The question is how we help people balance their diet so that they're not facing lifethreatening,preventable illnesses,but they're enjoying their food,they're eating their vegetables,they're doing their running,walking and playing,and they still have time to get a good,fun meal every once in a while." One in three American children are overweight or obese,putting them at the higher risk of developing diabetes ,high blood pressure,high cholesterol and other illnesses. Billions of dollars are spent every year treating obesityrelated conditions. "None of us wants this future for our kids," Mrs.Obama said at the White House. "We have to act,so let's move." Her campaign has four parts:helping parents make better food choices,serving healthier food in school vending machines and lunch menus,making healthy food more available and affordable,and encouraging children to exercise more. The campaign,which Mrs.Obama starts,is aimed at solving the childhood obesity problem in a generation,so that children born today can reach adulthood at a healthy weight. "This isn't like a disease where we're still waiting for the cure to be discovered.We know the cure for this," she said at the opening ceremony. President Barack Obama praised his wife for solving what he called one of "the most urgent health issues facing the country".

mmlu_train_59615 | Car companies are developing vehicles that will plug into electric sockets,just like many laptops,digital cameras,cell phones and Mp4 do.Called"plug-in vehicles",these cars will get most of their power from electricity. Their drivers won't have to stop at gas stations as often as usual. The technology is more than just cool. In our car-filled world,plug-in vehicles could reduce the amount of gas we use,which keeps rising in cost now and then. Besides,driving around in these vehicles may even help the environment.Gas-burning cars produce a lot of greenhouse gas,which causes globe warming. The first company-produced plug-in vehicles could hit the roads by 2010. But engineers still have a lot of work to do to make the technology practical and inexpensive. Batteries are the biggest challenge. In the plug-in-vehicle world,Li-ion batteries are getting the most attention.These batteries can store a large amount of energy in a small package,and they last a longer time between charges.Li-ion batteries can fit laptops,cell phones,heart instruments and other similar pocket ones. But because cars are so big and heavy, it would still require a suitcase-sized Li-ion batteries to power about 12km of driving.What's more,the batteries are much expensive. "A car filled with batteries could go a long distance,"says Ted Bohn, an electrical engineer in Chicago."But it couldn't pull any people.and it would cost $100,000." So researchers need to work out how to make batteries smaller and cheaper,among other questions. "The answers don't exist yet,"Bohn says,"As a kid,I thought someone someplace knows the answer to everything.All of these questions haven't been decided.That's what engineering is about-making a guess,running tests and getting fine results."

mmlu_train_30065 | Last March, the H7N9 virus hit Shanghai, Anhui, Jiangsu, Zhejiang and so on. It seemed that most people who were infected with H7N9 had the common flu . Some people suffered from a fever or a cough. Don't be afraid--it's not easy to be infected with the virus. Here is some advice to help you protect yourself when it comes. Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet, and after you touch animals, because your hands may carry viruses. Cover your nose and mouth. When someone sneezes or coughs, flu viruses can travel as far as one meter through the air, so you'd better stand a proper distance while talking to someone who has a cold. And always cover your mouth and nose with a piece of paper when you sneeze or cough, and then clean your hands. Wear a mask . Some doctors say that masks can stop the flu as much as 80%, but if you don't wash your hands often, it's no use wearing a mask. And it's necessary to wear the mask in the groups of people. Do sports often. Exercises will help make your body strong enough to resist the virus. When did the H7N9 virus hit Shanghai? | [

On Friday, three men came into the hotel and asked for rooms. Mr. Knight said there were no rooms ready because of the meeting. The men were unhappy. Mr. Knight wanted to help them. He remembered that Room 418, a small room, was empty. He asked them if they could share a room. The three men said they would. Mr. Knight said the room would be thirty dollars; ten dollars for each person. Each man gave him the money and then went up to the room. Mr. Knight soon began to feel sorry. "Thirty dollars is a lot to ask as a price for that small room." he thought. He called his assistant over and said, "Here is five dollars. Take it to the men in Room 418. I asked too much for their room." The assistant took the money. While he was on the way there, he started to think, "How can three men divide five dollars?

It is thought that we won't have to go shopping because we will be able to get most things which are sold in shops on the Internet. There will be fewer books because we will be able to get all texts from computers. The Internet will be used to play games, see films and buy food. Most telephone calls will be made by computers, too. Some people are glad about these new ways of shopping and communicating . Others do not think that computers will replace our old ways. Let's take books for example. Some people think that one day we won't read books made of paper. Instead, we will buy and read books using computers. We will read texts on small pocket computers. The computers will keep many different books in them at the same time. We won't need to turn lots of pages and paper will be saved. Computerized books will be used more and more. Is Internet shopping such a pleasure as going to the shop? Many people say it is not. It is a pleasure to go into shops and look at things you want to buy. It is also unlikely that many people will want to read large texts on our computers. Because paper books will perhaps be more friendly. Maybe computers won't change these two habits .

mmlu_train_40636 | Wouldn't it be great if you could just look up at the sky and read the weather forecast right away? Well, you can. The forecast is written in clouds. If you can read that writing, you can tell something about the atmosphere. With some practice, you can become a pretty good weather forecaster. Who knows, you might even do as well as meteorologists . Meteorologists use much more information than just the appearance of the clouds to make their forecast. They collect data from all over the world. Then they put it into powerful, high speed computers. This does give the meteorologists an advantage, because they can track weather patterns as they move from west to east across the country. But you have an advantage, too. You can look at the sky and get your data directly. A meteorologist uses a computer forecast that's several hours old to make a local forecast. What are you seeing when you look at a cloud? "A picture of moisture is doing in the atmosphere," says meteorologist Peter Leavitt. There's moisture throughout the atmosphere. Most of the time you don't see it, because it's in the form of an unseeable gas called water vapor. Sometimes, the temperature of the air gets cold enough to cause the waster vapor to change to liquid water. It's called condensation , and we see it happen all the time (for example, when humid air from the shower hits the cold glasses of a mirror). When enough water vapor condenses , droplets come in the air. These droplets scatter light. A cloud is seen. Watching clouds over a day or two tells you a lot more than a single cloud about the weather to come. Changes in clouds show changes in the atmosphere. You should begin to notice patterns. Certain clouds, following each other in order, can signal an approaching storm. But don't take our word for it; see for yourself. Meteorologists can make their weather forecast _ . | [

mmlu_train_41854 | Rain and cold weather this summer saw honey yields from hives fall by almost three-quarters, the British Beekeepers Association(BBKA)said today. The average crop per hive was down 72% compared to last year, with just 3.6kg (81b) of honey produced compared to an annual average, the annual honey survey by the BBKA revealed. The survey of 2,712 beekeepers in England, Northern Ireland and Wales found that 88% said this summer's bad weather caused the _ in honey yields. The bad weather made it difficult for bees to excrete ,which led to disease easily, and the bad weather also increased the risk of keeping bees for heavy rain caused the places which bees regularly visited to meet natural disasters. The bad weather also influenced the plants flowering which increased the cost of keeping bees. The BBKA issued a midsummer warning to feed bees if necessary to avoid dying from hunger. But in London, which recorded the worst results with just 2.5kg (5.61b)of honey harvested on average, beekeeping experts said that in addition to the bad weather there was a lack of food for bees in the city. Angela Woods, secretary of the London Beekeepers Association, said, "Rather than putting beehives on office roofs, we encourage companies in London that want to help to look at different ways of supporting bees and beekeepers. We need more food for the bees and better-educated beekeepers." Elsewhere, the weather was the main problem. Peter Hutton, a beekeeper in Tunbridge Wells, Kent, said, "It has been the most difficult year I have known in my 53 years of beekeeping. Bad weather in spring prevented bees in many areas from collecting nectar from early-flowering crops such as oilseed rape ,and the rain continued in many places throughout June and July, preventing honeybees from searching for food on later crops." The BBKA warned that as well as reducing the honey harvest, the bad weather is likely to have a longer-term influence as it will have affected the normal process of breeding for the queens, which mate on the wing on fine, still summer days. As a result they may have mated poorly and be unable to produce enough new babies to see groups through the winter. What caused the lack of food? | [

mmlu_train_16458 | Why are people interested in eating raw foods or whole foods ? One reason is that eating these types of food reduces the risk of acid accumulation in your body. Raw and whole foods are usually digested more efficiently than cooked foods. When we cook foods, we destroy the natural enzymes that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is overweight. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive system, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs. Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we've had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells. The body's metabolism becomes inactive, and the result is weight gain and obesity. The accumulation of acid in the digestive system makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common. To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It's also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach. One effective way is to choose raw and whole foods appropriately according to your health conditions and personal preferences. It can be inferred from Para. 2 that _ . | [

mmlu_train_28803 | A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again. Instead of satellites, Locata uses ground-based equipment to send a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim that the receivers can be shrunk to fit inside a regular cell phone. Even the US armies, which invented GPS technology, signed a file last month agreeing to a test of Locata at the White Sands Missile Range in New Mexico. "This is one of the most important technology developments for the future of the positioning industry," says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia. As for the Locata's correctness, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18cm along any axis . Morin said it should be possible to get the _ down to 5cm. The tests were performed in an open desert where GPS also worked beautifully, but its signal was weak--like a car headlight from 20,000 kilometers away--and easily cut off by solid objects . Locata's signal was far stronger, though not guaranteed to work in a complex urban environment, said David, speaker of the UK' s General Lighthouse Authorities. Locata's technology will face competition in the race to transform indoor navigation. But it could shine in specific areas, Gambale said. Robots with Locata could easily navigate inside buildings without the complex optical systems they need at the moment. And the process that handles correct location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. It would be small and cheap enough for smart phones and it should be available within five years--a similar path to the one GPS took on its way towards the world, he said.

mmlu_train_32737 | Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives -either recorded or real-may even prevent elephants from damaging farmer's crops. In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away. Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next,Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family. From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place. Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away. As mentioned in the passage, Lucy | [

mmlu_train_52388 | In many parts of the world, cars play an important role in daily life and many societies would not exist without them. So the idea that in 20 years' time, no one will own cars may be hard to believe. But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by car manufacturers. The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. The team there believes that by 2020 all cars will be computerized. That will mean much saving, no accidents and better use of roads. The super-intelligent car in the future will drive itself. And it will not be owned by one individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing. According to Dr. David Davis, who leads the research team, these predictions are based on the rising cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths than both world wars put together. Davis says, cars will be fitted with some intelligent devices to regulate the distance between one car and another. The car will automatically speed up, or slow down, to match the speed of the car in front. computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people. By 2016, Dr. David Davis believes, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead on to the car's windscreen. And by 2020, cars will travel in line, linked to each other electronically. Cars will be connected by an electronic tow bar to the car in front to form "road-trains". "The front vehicle in such a train burns the normal amount."says Davis. "but all the others in the train would burn about ten percent of the normal amount, and so produce about ten percent of the pollution."

This is one of the "pearls of wisdom" that are supposed to help us live a healthy life. Such common beliefs, however, lack scientific basis, according to a paper published recently in theBritish Medical Journal. Do you believe in the following everyday wisdom? Reading in dim light ruins your eyesight. In dim light, you might blink more, feel discomfort from drying and have trouble focusing. But the majority of eye experts believe it is unlikely to do any permanent damage. We must drink at least eight glasses of water a day In 1945, the Nutrition Council in US suggested that people need to consume 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total. We only use 10 percent of our brains. This myth arose as early as 1907. People have long argued about our power of self-improvement and our brains' potential abilities. But detailed imaging shows that no area of the brain is silent or inactive. Shaving your legs causes hair to grow black faster and thicker. This theory is also illusion.

mmlu_train_20833 | Think about what you usually have for a meal: Is it a hamburger? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet? It can--in a big way. Scientists attending the American Association for the Advancement of Science meeting in Chicago presented new studies showing how food and its production affect the globe and its warming climate. It is generally believed that global warming is caused by the large amounts of greenhouse gases released into the atmosphere. One of these greenhouse gases is carbon dioxide. What does this have to do with food? A big part of the carbon dioxide comes from the process of making and eating food, the scientists reported in Chicago. The production of meat contributes to a lot of that carbon dioxide. The process of making a hamburger, for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow manure is a major source of methane --an especially powerful greenhouse gas. By the time a hamburger is finally served on a dinner plate, it has done great harm to the environment. The message from the research is clear: We can greatly reduce the production of greenhouse gases by eating less meat. All kinds of meat, the scientists reported, are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide or other greenhouse gases into the air. So shifting our diet to less meat and more vegetables ,as it turns out, may do the world some good. According to the passage , the writer seemingly intends to _ . | [

mmlu_train_54096 | Except for the sun, the moon looks like the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter is only 2,160 miles (3,389 km), or a little more than a quarter of the diameter of the earth. Once a month, or more exactly, once every 29.5 days, at the time we call "full moon," its whole _ looks bright. At other times only part of it appears bright, and we always find that this is the part which faces towards the sun, while the part racing away from the sun appears dark. People could make their pictures better if they kept this in mind -- only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It only throws back the light of the sun, like a huge mirror hung in the sky. Yet the dark part of the moon's surface is not ly black; generally it is just light enough for us to be able to see its outline, so that we speak of seeing "the old moon in the new moon's arms." The light by which we see the old moon does not come from the sun, but from the earth. We know well how the surface of the sea or of snow, or even of a wet road, may throw back uncomfortably much of the sun's light onto our faces. In the same way the surface of the whole earth throws back enough of the sun's light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark. Why is the dark part of the moon not completely black? | [

mmlu_train_16673 | "Hey, don't read in the hallway. Your eyesight will be damaged." You must have heard such warnings many times. Don't read in dim light! This is one of the "pearls of wisdom" that are supposed to help us live a healthy life. Such common beliefs, however, lack scientific basis, according to a paper published recently in theBritish Medical Journal. Do you believe in the following everyday wisdom? Reading in dim light ruins your eyesight. In dim light, you might blink more, feel discomfort from drying and have trouble focusing. But the majority of eye experts believe it is unlikely to do any permanent damage. We must drink at least eight glasses of water a day In 1945, the Nutrition Council in US suggested that people need to consume 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total. We only use 10 percent of our brains. This myth arose as early as 1907. People have long argued about our power of self-improvement and our brains' potential abilities. But detailed imaging shows that no area of the brain is silent or inactive. Shaving your legs causes hair to grow black faster and thicker. This theory is also illusion. Shaving has no effect on the thickness or rate of hair growth, studies say. Just over time, the edge of hair gets worn away and thus the edge of long hair becomes finer . So hair that is newly grown gives the impression of darkness. This passage is most likely to be found in _ ? | [

mmlu_train_41675 | Anyone who ever wondered why a dying plant, say, a freshly-cut red rose may appeal to a lady friend, might take some comfort in science, which once again offers us a reasonable answer to one of the world' s great mysteries. Beyond a common preference in people for blue, "the long history of color preference studies has been described as 'confusing and contradictory '," write scientists Anya Hurlbert and Yazhu Ling of England' s Newcastle University, authors of a new study in the journal Current Biology. "This fact is perhaps surprising," they said, "though the popularity of the concept that little girls differ from boys in preferring pink." But the scientists believe they have an answer to this scientific mystery, discovering women's preference for red, hidden above the average liking for blue. In their study, the pair quickly flashed color cards, displaying many different aspects, at 208 volunteers, mostly Britishers but with a number of Han Chinese, who moved to the United Kingdom recently. Tested in three different experiments, the researchers found out a small but significant preference for reddish colors in the female volunteers. Puzzled, the authors realized that most of the difference between men and women came in the form of a preference for green VS red in the color cards, regardless of the other slight differences such as the slightly blue ones that everyone liked. Why might this be? Evolution might offer an answer, they reason. Human color perception , the assessment of three separate color types -- red -- green -- blue-- in our vision is a relatively recent addition to our line of mammals Adding weight to their argument, they found the women who are most typically feminine on a psychological survey also had the biggest preference for reddish colors. "My love is like a red, red rose," wrote the Scottish poet Rober Burns in 1794. According to the passage, _ . | [

mmlu_train_8295 | The year is 2094. It has been announced that a comet is heading towards the Earth . Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth. On 17 July , a piece four kilometers wide enters the Earth's atmosphere with a massive explosion . About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned. Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won't escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero .Crops are ruined. The sun won't be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive. Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared.

mmlu_train_21539 | -American office workers spend an average of 52 hours a week at their desks, according to a statistic survey. Some might argue that not all that time is spent working,but still all those hours in windowless offices with artificial light can have an influence. A few green additions could have a large effect on worker happiness,according to the survey led by Tina Cade from Texas State University. "We pretty much found out that if you had windows and plants or even if you just had plants in your office, you were more satisfied with your job," Cade told LiveScience. "We thought it was important for offices because a lot of times people are looking for ways to keep employees happy and do all these expensive things like building a gym. Maybe for less investment they could put in a few plants in important places." The team surveyed 450 office workers in Texas and the Midwest,asking questions about job satisfaction and the work environments. When asked about their overall life quality,82 said they felt "content" or "very happy". Only 69 percent of those who work with plants but without windows,and 60 percent of those who have windows but no plants, said they felt this way. The group of people who work without plants or windows were the most dissatisfied,with only 58 percent of them saying that overall they were "content" or "very happy". While no one who works with plants,windows,or both reported they felt "miserable", 0.8 percent of those who work in offices without either said they were "miserable". "I was really surprised that having a plant in your office appeared to be more beneficial than having a window in your office," Cade said. "Everybody says, 'I need a window!' but actually it seemed like a plant could be a suitable alternative." Among the 450 people surveyed, _ . | [
