It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever. Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours' sleep every night. If you go to bed late, you can't have enough sleep. Then you can't think carefully and your homework will be wrong. You will not be wise and you may not become wealthy! Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong. Exercise helps the blood to move around inside the body. Blood takes nutrition to all parts of our bodies. The brains in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better! Our bodies also need air to breathe .

She looked after them very carefully, and when the summer came, they looked very nice. One evening Mrs. Brown looked at her vegetables and said, "Tomorrow I am going to pick them and we can eat them." But early the next morning, her son ran into the kitchen and shouted, "Mother, mother! Come quickly! Our neighbor's ducks are in the garden and they are eating our vegetables!" Mrs. Brown ran out, but it was too late. All the vegetables are finished! Mrs. Brown cried, and her neighbor was very sorry, but that was the end of the vegetables.

The Chang'e-3 spacecraft is the second phase China's lunar rogramme, which includes orbiting, landing and returning to Earth. It follows the success of the Chang'e-1 and Chang'e-2 spacecraft in 2007 and 2010. The launch of Chang'e-3 was successful. The Chang'e-3 is one of the most difficult tasks in China's space programme, the news says. The news adds that exploring the universe and seeking peaceful use of space are dreams of Chinese for thousands of years. With a lander and the moon rover Yutu, Chang'e-3 soft-landed on the moon at 9:11 p.m. Saturday. Yutu later separated from the lander and ran to the moon surface earlier Sunday. China has chosen the name Yutu for its first moon rover, after a worldwide online vote attracted people to come up with names. In Chinese folk tale, Yutu is the white pet rabbit of Chang'e, the moon goddess. Chang'e took her pet and flew towards the moon.

mmlu_stem | mmlu_stem_7185 | Today, many people use plants from other places to design their yards. Well, do they have any influence on animals living nearby? As we know, plants supply food for things like insects and plant-eating animals. In turn, birds and meat-eating animals feed on these insects and plant-eating animals. It is easy to see how important plants are. Although foreign plants may look beautiful, they can cause problems when there are too many of them. I live in Virginia, USA, and sometimes see a plant--commonly known as Kudzu--that seems to cover everything in the area, even climbing over whole trees and houses. Kudzu is an unbelievable plant since it grows very fast. It was first brought to the United States from south-east Asia around the 1870's as a crop that farmers could grow. However, Kudzu quickly came to be considered harmful throughout the southern United States. Since Kudzu grows fast in many different environments, it can completely cover areas of land quickly. The plant is also not eaten by any insects or birds in the United States so it can grow unchecked. Kudzu can cover trees, bushes, and even houses. It costs the United States 500 million dollars a year to just keep Kudzu from growing too fast. The plant is a perfect example of what scientists call an invasive species, which grows more quickly than other native plants. All foreign plants have the possibility to spread quickly. Not only are they costly, but planting them in gardens actually takes away food from insects. If everyone filled their garden with plants native to where they live, many lovely butterflies and other native creatures would be attracted to their backyards! So, take a look out of your window -- how does your garden grow? We can learn from the text that Kudzu in Virginia _ . | [

mmlu_stem | mmlu_stem_4544 | Online clothes shoppers will be told exactly what size is best. for them using new software which combines with their web camera or smart phone to form a"3D tape measure". Scientists from Surrey University and design experts from the London College of Fashion are developing a program which can take precise waist, hip, chest and other measurements from camera images. Using the person's height as a starting point,the software will be able to build up a 3D image and estimate their size at various different points on the body, based on their overall proportions. The result will be a more accurate sizing guide than previous systems based on waist size or a "small/medium/large"scale, which rely on limited measurements and the buyer's perception of their own body size. Shoppers and retailers who choose to sign up for the project could save millions of pounds a year in postage costs by removing the need to order multiple sizes of the same garment and send back ill-fitting clothes, researchers claimed. The project, sponsored by the Engineering and Physical Sciences Research Council(EPSRC), is expected to be brought to market within two years. After choosing an item, the shopper will activate the software, enter their height, stand in front of their webcam or smart phone in their underwear and take a photograph. The software will not store or transmit the image to the internet, but will use it to judge the person's dimensions at various points on their body. Philip Delamore of the London College of Fashion said:"The potential benefits for the fashion industry and for shoppers are huge. Currently, it's common for online shoppers to order two or three different sizes of the same item of clothing at the same time, as they're unsure which one will fit best."

The images had better match---otherwise, you won't be able to get your money. Iris scanning and other technologies, such as fingerprint and voice scanning, have appeared in many science fiction movies in the past. Today, these advanced technologies are part of the real world. They are common at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics , a fast developing area of automatic personal identification technology. Basically, biometrics uses various ways to verify a person's identity, based on the individual's unique characteristics, including fingerprints, signature, and so on. Biometrics identification systems have a number of advantages over password systems. The primary advantage is that an individual has to be physically present in order to be identified. Another important advantage is that there are no passwords to remember, forget, lose, or steal. The voice scan is the simplest and most affordable form of biometrics. It only requires a computer, a microphone, and the correct software. The software records a subject's voice and then compares it to a stored voice sample for identification purpose. For additional safety, fingerprint and handprint scans can also be employed. Fingerprint scans take the image of a fingerprint and compare it to a stored file of prints. Handprint scans identify the unique features of a hand. Which is the most accurate form of biometrics? | [

However,the buyer did not bring any money.He brought the police.The poachers were arrested on the spot but the police knew the orphan was still in danger.They had rescued baby gorillas before and understood that they needed to act quickly.They rushed the young gorilla to the nearby Mountain Gorilla Rescue Centre.The vets there realized that she had not been given enough food or water, but they were much more worried about something else.The baby gorilla,which was later named Dunia,had not been getting enough touch. "Baby gorillas simply don't survive without their mother's constant body contact," says Chris, a vet."They give up the will to live."The project's staff immediately began holding and hugging Dunia,the little baby gorilla. Dunia resisted attention at first, shying away from people who reached for her. "She needed contact, but there is no reason that she should trust people after what she'd been through,"says Christ."Humans had killed her family." Although she became stronger a month after she was recued, her appearance revealed the psychological stress she carried inside--much of her hair had fallen out.That was a delayed reaction to the combined terrible experiences of losing her parents and being kept with a poor diet by the poachers. After six months of loving care, a good diet, and a comfortable home at the centre, Dunia was looking and acting like a healthy, happy young gorilla should. What can we learn about the buyer? | [

mmlu_stem | mmlu_stem_2933 | Certainly no creature in the sea is stranger than the common sea cucumber . All living creatures, especially human beings, have their features, but everything about the little sea cucumber seems unusual. What else can be said about an unusual animal that eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered eatable? For some fifty million years, in spite of all its strange features, the sea cucumber has lived on its diet of mud. It is adaptable enough to live attached to rocks by its tube feet, under rocks in shallow water, or on the surface of mud flats. Common in cool water on both Atlantic and Pacific shores, it has the ability to suck up mud or sand and digest whatever nutrients are present. Sea cucumbers come in a variety of color1s, ranging from black to reddish-brown to sand-color1 and nearly white. One form even has brilliant purple tentacles . Usually the creature are cucumber-shaped--where their name comes from--and because they live in rocks, this shape, combined with flexibility, enables them to press into crevices where they are safe from animal eater and ocean currents. Although they have greedy desire for food, eating day and night, sea cucumbers have the ability to become still and live at a low metabolic rate--feeding a little or not at all for long periods, so that the living things in the ocean that provide their food have a chance to increase by a large amount. If it were not for this natural ability, they would swallow all the food available in a short time and would probably starve themselves out of existence. But the most impressive thing about the sea cucumber is the way it defends itself. Its major enemies are fish and crabs. When attacked, it forces all its internal organs in its body out into water. It also removes attached structures such as tentacles. The sea cucumber will get rid of its organs and grow itself again if it is attacked or even touched; it will do the same if the surrounding water temperature is too high or if the water becomes too polluted.

mmlu_stem | mmlu_stem_5701 | What do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist may be able to put the tooth back in for you, but you have to get to the dentist first.In the meantime, you have to store the tooth so that it will stay healthy. The simplest thing to do is put the tooth back into your mouth, or you could put it in milk.Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth.He tried putting teeth into milk, into water, and into cell-culture medium .He also tried, just drying the teeth in the open air.He used teeth that had to be removed from people's mouths for various reasons.The teeth were put into one of the solutions or stored in the air for one hour.Then cells from the root of the teeth were scraped-off the teeth.Dr.Courts and the others then studied how healthy these cells were. The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth.However, few people keep cell-culture medium handy at home or in school. The next best thing was milk.But Dr.Courts said that the best thing of all was to wash the tooth and put it right back into its socket in the mouth.For some people, though, this is just too painful or upsetting.So milk will do, until you get your tooth (and your mouth)to a dentist.

mmlu_stem | mmlu_stem_7313 | Next Stop: Planet Mars Fly me to the moon? That's not far enough. On September 14, 2011, NASA released designs for a superrocket, the Space Launch System (SLS). This time the final destination will be Mars. The SLS is a huge, liquid-fuelled rocket. If it is fully developed, it will be the most powerful rocket ever built. Its lift capability will be much bigger than that of the space shuttle of Saturn 5, the rocket that sent the Apollo missions to the moon. NASA is planning to launch its first unmanned test flight in 2017. It is hoped that the first crew will fly in 2021 and astronauts will make it to a nearby asteroid in 2025. NASA hopes to send the rocket and astronauts to Mars from the asteroid by the 2030s, according to the Associated Press (AP). NASA used liquid rockets to send Apollo, Gemini and Mercury into space, but later changed to solid rockets boosters because they were cheaper. Tragically, however, a booster flaw caused the space shuttle Challenger to crash in 1986. The new project plans to return to liquid fuel. According to AP, the rockets will at first be able to carry 77 to 110 tons of payload . Eventually they will be able to carry 143 tons into space, maybe even as many as 165 tons, NASA officials said. By comparison, the Saturn 5 booster could lift 130 tons and the space shuttle just 27 tons. However, unlike reusable shuttles, these powerful rockets are mostly one use only. New ones have to be built for every launch. This will be very costly. NASA estimates that it will cost about $3 billion (19 billion yuan) per year, or $18 billion until the first test flight in 2017. NASA hopes to make money by allowing private companies to send astronauts to the International Space Station like giant taxi services, so that the program can be "sustainable". "This is perhaps the biggest thing for space exploration in decades," said Senator Bill Nelson, a former astronaut. "The goal is to fly humans safely beyond low-Earth orbit and deep into outer space where we cannot only survive, but one day also live."

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

But it seemed that the more he believed he could do it, the easier it was. "I'm not a joke now," thought Joe. "Not a joke at all!" But a practice wasn't like a real match and his boots were still not giving him enough power. He should have told his mum and dad about it straight away but, of course, he didn't. He was always shy to ask for things. Finally, late on the night before the match, he could hold himself back no longer. "Dad, I haven't got any proper football boots ..." he said. "Ah," said Dad, "I might be able to help you there." At the words, Joe was excited. New boots! He thought. "He's got me some new boots! He must have got me them for Christmas," thought Joe, "But now that I'm in an important match, he's giving them to me early. Wonderful!" Dad went upstairs. Joe excitedly tried to watch the football preview on TV. He wasn't playing for Manchester United or Liverpool, of course, but he was part of it all now; part of the thrill. His legs twitched with every kick on the screen. His head shook with every centre. And all the time, his mind was racing ahead to his own great game the next morning, in his super new boots. It was ages before his dad came downstairs again. He put a large pair of shiny black boots in front of Joe. As he stared at them, the boy felt as if someone had poured ice into his brain. The boots were awful! "Good, eh?" said his dad. Joe found it hard to speak. He had never seen anything like them before. They weren't low-cut, soft or.... They had big, hard square toes, great big long studs and they were high at the ankle. They were his dad's old rugby boots, polished up. Joe was filled with disappointment. They had been good boots, quality boots. And they were his size. Joe's feet were enormous for his age. But he could imagine what everyone at school would say. " ...," he finally gasped, " should be exactly my size." "At least I won't slip," he thought, "the studs are like sharks' teeth!" Then he couldn't help thinking about those in Ashton's windows, which he had been longing to get. That night, he went to bed early but he didn't sleep much because he was so terrified of being late. He woke at 1.17, 2.49, 3.37, 3.43, 4.55. The numbers jumped off the big face of his digital clock. Then 10.40! Ahhh!!! He jumped out of bed. He seized the clock. 6.03! 10.40 had been only a dream. At eight, breakfast time, it was raining like mad. "Might get called off, Joe," suggested his mum. "Never, Mother. ...will not be like cricket," said his dad. "Will take a lot to stop football." Joe checked everything for the tenth time. He put his boots at the very bottom of his large bag, well out of sight. He had decided to put them on when nearly everyone had left the changing room. Then his classmates wouldn't make fun of him. Soon, it was time to set out. "Good luck!" said his mum, giving him a kiss. His dad had his coat on, ready for his morning deliveries. "Want a lift to school?" he said. "I hope to get down to watch you when I've done the trip to Eccles." "Okay," said Joe. As Dad's van carried him down the hill to school, Joe was thinking about the boots. If only ... but no, he had to stop that kind of thinking. It doesn't matter about the boots, he told himself.

He received agreement from state officials to test this idea at a prison . Prisoners were offered pardons if they took part. One group of prisoners received their usual food, mostly corn. A second group ate meat, fresh vegetables and milk. Members of the first group developed pellagra. The second group did not. But some experts refused to accept that poor food caused pellagra. They thought there were other causes. So Doctor Goldberger put blood from a person with pellagra into his own body. He even took pills that had blood from pellagra patients. An assistant also took part in the experiments. So did Doctor Goldberger's wife. None of them got sick. Later, the doctor discovered that a bit of dried brewer's yeast each day could prevent pellagra. Joseph Goldberger died of cancer in 1929. He was 55 years old. Several years later, researchers discovered the true cause of pellagra: having little of the vitamin B. How old was Doctor Goldberger when he began to study pellagra? | [

mmlu_stem | mmlu_stem_11866 | From our smartphones to our latest weaponry, the technology that underpins modern life would be impossible without rare earth metals. The importance of rare earths has only grown as emerging markets increase their demand for technologies made with it, as does the renewable energy industry. The 17 metallic elements are common in the earth-s crust, but the technique used to extract and refine them is labor-intensive, environmentally hazardous and increasingly costly. Thomas Gradael, a professor of geology and geophysics at the Yale School of Forestry Environmental Studies, explains that thecriticality" of rare earths was only recently understood after China, which dominates the world-s supply of the minerals, cut exports by 40% in 2010, citing concerns over how polluting the rare earth industry was. Along with colleagues at Yale, Gradael decided to investigate the metals used in modern technologies to determine if there were viable substitutes."Twenty or thirty years ago electronics were being made with 11 different elements," explains Gradael. "Today's computers and smartphones use something like 63 different elements." Their findings showed that there were no "readily apparent" substitutes for a metal that would not compromise on quality or performance. However increased mining for these scarce resources can have some nasty side effects for the environment. China, which has intensively mined for rare earths with little regulation, allowing it to dominate the global industry since 1990, has acknowledged the incredible environmental harm caused by the process. "Excessive rare earth mining has resulted in landslides, clogged rivers, environmental pollution emergencies and even major accidents and disasters, causing great damage to people's safety and health and the ecological environment," read a white paper issued by the Chinese cabinet in June last year. Recycling metal has been advocated by some as a possible way of managing these precious resources-the European Parliament adopted a law curbing dumping of electric waste in 2012. But Gradael says that for rare earths, recycling will have little impact. Gradael investigated the use of rare earths in modern technologies to _ . | [

mmlu_stem | mmlu_stem_15015 | Space vegetables are grown from seeds that have been taken to space and brought back to the earth. The seeds are affected by the radiation and low gravity in space. When they are brought back to the earth, these seeds produce vegetables that are bigger and healthier than normal vegetables. However, some people worry about eating space vegetables. They think that space vegetables might not be good for us and could make us get sick because of the radiation in space. However, people should not be frightened because space vegetables are very healthy. Here are some facts that you should know about space vegetables. Space vegetables are grown from seeds that are carefully chosen. When seeds are brought back from space, they are tested to make sure that they will be safe to eat. Space vegetables are better for you than normal vegetables. For example, space tomatoes stay fresh for twenty days, which is one week longer than normal tomatoes. After genetically modified food appeared in the market, people worried that they were eating unknown things. For example, if nut genes are put inside potatoes, people allergic to nuts might get sick from eating these potatoes because they do not know they are also eating nuts. Unlike genetically modified food, space vegetables have not been genetically changed. This means that no new genes are put into the vegetables. Therefore, there are no dangers of eating something unknown. The writer wants to tell us that _ . | [

mmlu_stem | mmlu_stem_6970 | In the hot jungles of Thailand, forest rangers came across a terrible sight one day in 2010. Two tiger cubs lay dead in a wildlife preserve . The rangers were too late to find the cubs' mother. All that remained of her was blood on the ground. Poachers had poisoned the tigers. Then they ran off with the mother's body. If the rangers had not arrived, the poachers would have taken the cubs too. Tigers in trouble One hundred years ago, there were about 100,000 tigers. Today, only about 3,200 remain in the wild. Poachers are a major problem. These killers sell tiger fur, teeth, claws, and other body parts in illegal markets. One tiger's parts can see for $50,000. Because they hunt in huge jungles thick with trees, poachers are hard to find. But they must be caught, says Elizabeth Bennett of the Wildlife Conservation Society. This group works to help endangered animals. Tiger "fingerprints" Finally, after many months, the rangers spotted the poachers again. After an exchange of gunfire, they arrested the criminals. Soon, the police found evidence that the poachers had killed again. The evidence came from a cell phone. On a poacher's phone, police found photos of the men posing with a dead male tiger. The poachers claimed that the photos were from a nearby country where tigers aren't protected. But another photo told a different story. Deep in the Thai forest, the rangers had set up camera traps, which take photos when they sense movement. A camera trap photo showed the same male tiger walking through a wildlife preserve before he was killed. That meant that the tiger came from a protected area. But how could police prove it was the same tiger? Tiger stripes are like fingerprints. No two patterns are the same. When police compared the photos, the stripes on the tiger's head matched. The poachers were given up to five years in prison. That might not seem like much for killing tigers. But since the poachers were caught in July 2011, no tigers have been killed in that wildlife preserve. The author's purpose of writing this story is probably to _ . | [

mmlu_stem | mmlu_stem_6851 | For millions of years, sharks have been the kings of the oceans, the top of the food chain. But these days, the hunter has become the hunted, because of better methods from commercial fishermen who are looking for fins to make expensive soup sold mostly in Asia. Shark fins are far more valuable than shark meat, so fishermen cut the fins off live fish and throw the sharks overboard to maximize the catch they bring back. Shark finning is illegal in the United States, but there're tournament sport fishermen, who target and kill the biggest ones they take from the sea. These tournaments, the prizes of which can reach $5,000 or more, attract large crowds of anglers but also draw protests from animal rights groups and environmentalists. The competitors say they are enjoying a fun and legal sport, the impact on the overall shark population is very small, and most of the sharks caught are returned to the ocean. Dave Johnson, who is from Kennebunkport, Maine, said no one ever comes close to the limit set by the government of killing one shark per day during the three-month season. "I enjoy watching these animals, but I also enjoy catching and releasing them, and very rarely killing them and eating them," he said. "If I thought killing one shark was endangering the species and contributing to their decline I'd stop doing it tomorrow." That is exactly what marine biologists like Luke Tipple want to happen. "I believe that they should just stop it. In fact, we don't need to be targeting, in any way, any of these threatened populations," he said. Up to 73 million sharks are killed annually, and many species are at risk of extinction . Johnson's words suggest that _ . | [

mmlu_stem | mmlu_stem_8080 | What science fiction once told of other worlds far away is now a fact. Astronomers prove the existence of another solar system like ours with some planets in the constellation Andromeda . Geoffrey Marcy is a professor of astronomy and physics at San Francisco State University and says, "What we have found now, for the first time ever, is indeed a fully-grown system of planets around the star Upsilon Andromeda, in which there are three planets, one close in, one at a middle distance, and one farther out." The star is slightly larger than our sun. The planets are huge, like our Jupiter . Marcy's partner in this research, Debra Fischer, describes the solar system, "Here's the inner planet that goes around every 46 days, the middle planet that goes around every 242 days, and then the outer planet that goes around every three and a half to four years." Astronomically, it's not far away, 44 light years. The sun of that solar system, Upsilon Andromeda, is so near and bright that it can be seen by using no equipment during summer and fall. For twelve years astronomers searched the skies in the belief that if our sun has planets around it, surely others do, too. Geoffrey Marcy says, "And then starting three and a half years ago, we began finding for the first time planets singly, one planet here around one star." "When I look up at the stars now at night, I can imagine easily that every one of them has planets around them," says Debra Fischer. It was the tremble in the star that led Marcy to discover the planets. "The star rocks around due to the gravity of the planet much like a dog owner gets pulled around by a little dog." Can they support life? We don't know, because present technology is not advanced enough to determine what the planets are made of. That, Marcy says, is astronomy's next challenge.

Your home printer exactly shoots drops of ink onto a flat piece of paper, creating the robot's 2-D image. "Printing" 3-D objects is different. Take the purple robot. First select a file of the 3-D printer. Immediately, the printer begins making noise, and a nozzle releases plastic material in thin layers. In two or three hours, a 3-D purple robot is standing before you. 3-D printing has developed to the point where printers can now create high-quality objects using a variety of materials, including metals. That means 3-D printers can now make final products that meet high industrial standards. 3-D printers are already being used to make parts for racecars and jets as well as man-made limbs and hearing aids. So far, few homes have 3-D printers. That's because 3-D printing is not only new to most people but also quite expensive. To bring 3-D printing to the masses, some retail stores plan to offer the service. For example, the Staples chain of office supply stores has announced that it will offer 3-D printing in Europe beginning in 2013. Customers will be able to submit their own 3-D designs to Staples website for printing. After the job is done, they'll pick up their item at a nearby Staples store or have it mailed to their homes. This service is sure to encourage many more people to try out 3-D printing. What will customers need in order to submit their designs to Staples? | [

At bedtime we untie them and take them wherever we've chosen to sleep. On most space shuttle flights everyone sleeps at the same time. No one has to stay awake to watch over the space plane: the shuttle's computers and the enginers at the Control Office do that. If anything goes wrong. The computers ring a warning bell and the engineers call us on the radio. On the space shuttle, sleep-time doesn't mean nighttime. During each ninety-minute flight around the earth, the sun "rises" and shines through our windows for about fifty minutes: then it "sets" as our flight takes us around the dark side of the Earth. To keep the sun out of our eyes, we wear black sleep masks. It is surprisingly easy to get comfortable and fall asleep in space, and we sleep differently. Some sleep upside down, some sideways, some right side up. When it's time to sleep, I take my bag, my sleep mask, and my tape player with earphones and float up to the flight platform.

Their eyes will be open but they will appear to be in a dream-like state, and will probably not answer when you talk to them, although they may carry out conversations. Sleepwalking can last a few seconds , a few minutes, or more. Sleepwalking can be an indication that certain parts of the brain may not be relaxing properly at bedtime. It can be caused by illness or fever, tiredness, stress or anxiety. It is thought to occur in the beginning, slow-wave stages of non-rapid eye movement sleep before dream sleep. It may be related to the lack of magnesium , and it is very possible that hormonal changes in body could cause it. Certainly a child is more likely to be a sleepwalker if one of his parents suffered, too . Sleepwalking itself is not dangerous and is generally not a sign of any more worrying problems. But if your child sleepwalks regularly, you have to take safety measures to make sure that he doesn't hurt himself while sleepwalking. Makes sure that any doors can't be opened by a child, and lock doors to the cellar, kitchen and other dangerous places. Check each night before lights go out for sharp objects or, indeed , anything on the floor which your child could trip over or hurt himself on. A child may sleepwalk once and never sleepwalk again. Others may sleepwalk once a month or so. Still others may sleepwalk almost nightly. If you are worried you should consult your doctor. Which of the following is true according to the passage? | [

As the weather gets colder and there is less sunlight, people are more likely to get sick. Adults in the US usually have two to four colds each year. Young children suffer from six to eight colds per year, especially in winter months, according to the American Lung Association. One of the best ways to keep healthy during winter is to stay warm. There are many ways to stay warm. A living room should be around 18-21 C, and you can also use a hot water bottle or at least 16 C. blanket to keep warm while in bed. Getting plenty of exercise is always a good idea. Take a walk on a sunny afternoon, do a long distance run or skip rope. These things keep your blood moving and your metabolism fired up. Food gives us energy and helps to warm us from the inside. High-protein foods, like fish and meat, provide a lot of energy. Add some things to your winter dishes, such as ginger, pepper and garlic. These things can make you warm. A winter coat warms you up from the outside. Add several layers of thin clothing, for example, a shirt and a thin sweater, to stay even warmer. Clothes made from wool are usually very warm. How to make winter days colorful? Is it too cold to play outside? Don't worry. Here are some tips for having fun at home. Give it a try! # Enjoy a movie with your parents. There are a lot of choices, such as Spy Kids. You can also talk about the movie with your parents after it's over. # Cook a meal with your parents. You can cook some simple dishes, such as scrambled eggs with tomato. You may need your mother's help for the first time. # Clean your bedroom.

If you don't have a schedule or plan for studying, you will have no way of allocating your valuable time when the unexpected arises. A well-thought-out timetable can be a lifesaver. It is up to you to learn how to develop a schedule that meets your needs. Change it if necessary, but most important, follow it . All timetables should be made with the idea that they can be changed. A good one will keep you from wandering off course. A good timetable should make every hour count--every class ,social event and other activity you engage in .You must focus on the other "free time" available and how you will use it .Make a weekly schedule and divided each day into one-hour increments. Indicate times for classes, socializing, and work time. Also block off a period for sleeping every day. In the precious hours left over, plan time for study. This gives you a rough road map of the time available. Of course, you can change your schedule as circumstances need. The timetable you develop should guide you in how to distribute the available time in the most productive manner. Sticking to your schedule can be tough, but don't dribble away valuable time. Avoiding study is the easiest thing in the world. It is up to you to follow the schedule you've prepared. A good deal of your success in high school and with any future study depends on this simple truth. Remember, there is a learning curve. You learn the most in the first 30 minutes of study; after that, it progressively deteriorates. After four or five hours of studying the same material in the same way, you are learning virtually nothing. The solution is to keep switching subjects and study styles. The following are characteristics of a good timetable EXCEPT that _ . | [

mmlu_stem | mmlu_stem_10630 | Auckland, New Zealand After two months of learning, Monty, and Porter were able to drive an automobile around a racetrack. "We wanted to prove how smart rescue dogs are," animal behaviorist Mark Vette says. Vette first used voice commands and treats to teach the dogs how to turn a steering wheel and how to change gear . The dogs' ride only accelerated up to 7.5 miles an hour, and trainers could stop the auto using a remote control. GOLDEN ZEBRA Kailua-Kona, Hawaii Zoe the zebra's markings are special. The animal has white and golden stripes. Zoe's appearance resulted from a rare condition called amelanosis . Her body doesn't make enough melanin, the substance in an animal's skin and hair cells that produces color. "Only 25 other golden zebras are known to exist in the world,"says Ann Goody, who runs the wildlife refuge where Zoe lives. In the wild, life may be difficult for animals with amelanosis because predators can easily spot them. But Zoe is protected at her refuge. COCKATOO MAKES TOOLS Vienna, Austria When Figaro the cockatoo spots food lying just out of reach from his cage, he builds a tiny wooden tool to sweep the tasty prize in his way. The bird first revealed his talent when a stone he was playing with rolled out of his cage. The cockatoo couldn't reach the stone. So he flew away and returned with a small branch, slipping it through the fence to slide the stone toward him. Wondering if he would do it again, scientists placed a nut exactly where the stone had been. This time, Figaro pulled out a small piece of wood in his cage and dragged the nut toward him. What' s special about Figaro the cockatoo? | [

mmlu_stem | mmlu_stem_10583 | Many scientists today are convinced that life exists elsewhere in the universe---life probably much like that on our own planet. They reason in the following way. As far as astronomers can determine, the entire universe is built of the same matter. They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in the same way as our own solar system. What we know of life on earth suggests that life will arise wherever the proper conditions exist. Life requires the right amount and kind of atmosphere. This eliminates all those planets in the universe that are not about the same size and weight as the earth. A smaller planet would lose its atmosphere; a larger one would hold too much of it. Life also requires a steady supply of heat and light. This eliminates double stars, or stars that flare up suddenly. Only single stars that are steady sources of heat and light like our sun would qualify. Finally, life could evolve only if the planet is just the right distance from its sun. With a weaker sun than our own, the planet would have to be closer to it. With a stronger sun, it would have to be farther away. If we suppose that every star in the universe has a family of planets, then how many planets might support life? First, eliminate those stars that are not like our sun. Next eliminate most of their planets; they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out. This process of elimination seems to leave very few planets on which earthlike life might be found. However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist. What kind of planet might NOT support life? | [

According to an internet survey, the incidence of _ during the festive shopping season is on the up. Christmas shopping increased blood pressure to dangerous levels in 50 percent of shoppers. This can lead to hypertension. Heart rates increased by an average of 10 per cent during Christmas shopping. In the study of 16 men and 16 women, men had the worst beating in heart rate during a 90-minute shopping. Samuel Thompson, 30, said: "I had to buy five items and had an hour and a half to buy them." "Normally, I know exactly what I want to get and do it as quickly as possible. But having to make on-spot decisions, like we did in the test, makes it more stressful." "Lack of time and the crowds were the biggest pressure points. I got frustrated by other people slowing me down by stopping to chat in the street. And I could feel myself sweating in queues. Everything took longer than planned." Dr Turner drew the conclusion: "Samuel's heart rate was good at the start but it had almost doubled by the end. Combined with his systolic blood pressure up by nearly 15 percent, it could put him in line for stroke . Systolic blood pressure relates to the pumping out of blood by the heart." Men suffer twice as much as women and are therefore in greater danger of dying on the High Street in the coming weeks. Remember, a husband is for life and not just for Christmas.

mmlu_stem | mmlu_stem_11836 | To what degree can a computer achieve intelligence?The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet. If you ran into Smarter Child online, you would be surprised at this kid's huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season. He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get strange answers. A question about Smarter Child's age returns, "One year, 11 days, 16 hours, 7 minutes, and 47 seconds!" Asking where he lives gets, "In a clean room in a high-tech building in California." Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www.intellicast.com. Some scientists believe that by joining the many systems of the Internet, an artificial being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However, if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I. Artificial Intelligence, he must solve two problems. The first is that computers find it difficult to read web pages because the files are sorted in different ways. That's why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself. Another problem is that while Smarter Child can process information more exactly and faster than any human, he lacks common sense--a basic grounding of knowledge that is obvious to any young child.

Lichens live on rocks, branches, houses, and even metal street signs. You can find these colorful organisms almost everywhere -- from deserts to rainforests, and from Antarctica to Africa. They've traveled in outer space, and some scientists think there might even be lichens on Mars. What you probably don't realize is that a lichen is more than a single thing. It includes two different types of living organisms: a fungus and an alga . Neither of these organisms is a plant, so the lichen isn't a plant either. Through photosynthesis , the alga gets the sun's energy to make food for the fungus, which is the place for the alga to live in. However, the alga cannot leave the fungus. Around the world, scientists have found tens of thousands of types of lichens. Many may not even have been discovered yet. As scientists continue to find new kinds of lichens, they are also working to understand how they are connected to one another.

mmlu_stem | mmlu_stem_3310 | Organic foods are foods produced according to strict guidelines set forth by the government. These guidelines state that organic foods must be produced without modern man-made processes and materials, such as man-made pesticides and chemical fertilizers . For most of history, almost all foods were organic. However, during the 20th century, the principles of the Industrial Revolution were applied to agriculture. This led to the development of many man-made processes that were believed to improve farming techniques. In other words, small farms grew larger as the ideas that were used by factories and big business were put into action to grow more food. Over time, the organic movement started to get back to the old, traditional methods of farming. Those in favor of organic foods believe that man-made chemicals and pesticides used in modern farming can be harmful to your health. They also believe that organic foods are more nutritious . If you go to the store, you will notice that organic foods may be more expensive than non-organic foods. Are organic foods worth the extra cost? Some people believe they are. Despite the lack of scientific findings to support their thoughts, many people still prefer organic foods because they think they taste better, while others don't care much about that because they say they haven't found out the differences. If you wonder whether you should choose an organic food instead of a non-organic one, the best thing you can do is to try it by yourself and see which you prefer. Although organic foods were once only available in health food stores, you can find them today at most stores. From the passage, we know that _ . | [

mmlu_stem | mmlu_stem_11827 | Kids love the all-knowing Google. Your kids likely use Google to help them find everything from information for homework assignments, to funny cat videos, and everything in between. Sometimes kids can take a "wrong turn" on Google and end up in a dark part of the Internet where they shouldn't be. Thankfully, Google has some parental control features that parents can implement to at least help reduce the volume of crap that ends up in search results,which can enable you to help keep your curious kids from ending up on the wrong side of the tracks. What is Google SafeSearch? Google SafeSearch is one of the primary parental control options offered by Google to help parents police search results. SafeSearch helps to filter explicit content out of search results. It is mainly designed to target sexually explicit material (images and videos) and not violent content. How to Enable Google SafeSearch?1. From the "Search Settings" preferences page, place a check in the box with the label "Filter explicit results". 2. To lock this setting so that your child can't change it, click the "Lock SafeSearch" link. If you are not already logged into your Google account, you will need to do so in order to lock SafeSearch to the "on" position. Enable SafeSearch on Mobile Devices. In addition to your computer, you will probably also want to enable SafeSearch on any mobile device that your child uses regularly. For instructions on how to enable SafeSearch on a variety of mobile devices, check out Google's SafeSearch Mobile support page. As we all know, kids are going to be kids and try to test their boundaries. We put up one roadblock and they go around it.

mmlu_stem | mmlu_stem_9843 | A new satellite is travelling 1.5 million kilometers over a 110-day period to enter an orbit of the sun. It is called DSCOVR--the Deep Space Climate Observatory. It will replace a satellite that has been observing space weather. DSCOVR will begin its work during the worst of the 11-year-long solar cycle. This is a time when extreme weather on the sun can have the greatest effect on planet Earth. DSCOVR will gather information about a continuing flow of particles from the sun. We are protected from these particles by the Earth's magnetic field and atmosphere. But we are not fully protected from what scientists call Coronal Mass Ejections. These are strong storms that can happen on the sun's surface. Thomas Berger is the director of the Space Weather Prediction Center at the National Oceanic and Atmospheric Administration, or NOAA. He says these ejections are much more dangerous than solar particles. He says the Coronal Mass Ejections are extremely large magnetic clouds that are expelled from the sun at extremely high speeds. He says when they impact Earth, it is like a hurricane impacting Earth in terms of space weather. Violent space weather can make electric systems stop working. It can block satellite signals to Earth. It can interfere with radio signals and air travel. Mr. Berger says we cannot stop the ejections from affecting us, but we can prepare for them if we know when they will happen. When the DSCOVR satellite records an ejection, it will release a warning. Mr. Berger says the warning will provide NOAA about 15 to 60 minutes to let people know that a very strong storm is coming in to the Earth. He says that is enough time for power grid operators to take protective action. He says it is also enough time for workers to place satellites on a safe operating method if necessary. Mr. Berger says scientists would like even more time, of course. He says researchers are developing instruments that will give an earlier warning. The warnings from DSCOVR will be for the whole planet. But Mr. Berger says a new system may be able to give more-targeted warnings. He says future models will be able to tell exactly what part of the world will be more at risk from a solar storm.

mmlu_stem | mmlu_stem_4206 | The current Ebola outbreak in western and central Africa has infected at least 3,069 people, including 1,552 dead, making it the largest outbreak in history. Ebola is a deadly virus --about 60 percent of people infected with it have died. How is Ebola doing its harm? When a person becomes infected with Ebola, the virus damages the body's immune cells, which defend against infection, said a researcher at Lancaster University. But if a person's immune system can stand up to this attack, then he is more likely to survive the disease. The patients that survive it best are those who don't get such a bad disadvantage in immune system. But if the body isn't able to get rid of this attack, then the immune system becomes less able to regulate itself. This means the immune system is more likely to run out of control, leading to a drop in blood pressure, multi-organ failure and eventually death. What are the common symptoms of the disease? Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body. How to prevent the spread of Ebola? Ebola can be spread primarily via direct contact with patients, specifically the blood and fluids of an infected patient. We should avoid contact with infected patients and objects such as clothing, bedding, and needles used by them. Avoid areas where infections have been reported. For now, the disease has only been confirmed in central and West Africa, four cases in America and Europe. Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals, probably through the meat of primates . If you're in an area where the disease has been reported, avoid purchasing, eating, or handling wild game to stay on the safe side. Wear protective medical clothing if you're around infected patients. Extreme caution is necessary. Hospital workers must use masks, gloves, goggles, and gowns, which needed to be worn at all times if you're around infected patients. How Do People Survive Ebola? Doctors don't know for certain who will survive Ebola, and there is no specific treatment or cure for the disease. Although in the minority, some people do recover from infection. Our suggestions include: Maintain your electrolytes and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygen-rich environment. Quickly address any symptoms of infection. Be honest about when and where you're feeling pain.

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. Which of the following is true according to the passage? | [
"Young elephants ignore African honeybees.",
"Waterfalls can make elephants stay in one place.",
"Elephants do not go near trees with bees living in them.",

mmlu_stem | mmlu_stem_14569 | Many people like animals such as dogs and cats and keep one or more of them as pets. If you keep a dog or a cat as a pet, you must know how to look after it. A grown-up dog needs two meals a day --not more. It can eat meat, fish, rice and some other things. Dogs like large bones , but you can't give them chicken bones. Remember to give them much clean water. A dog should have a clean, dry box for sleeping. Washing it once a week is good for its health. If it is ill, take it to a doctor. A healthy dog will bring you more pleasure. Be careful when you choose a cat. A cat has two meals a day with some meat or fish. It drinks a little milk every day. Sometimes you can give it vegetables to eat. Don't forget that it needs clean water to drink. Take good care of your pets, they will be your good friends.

mmlu_stem | mmlu_stem_6191 | Animals are considered to be endangered if the species is close to extinction throughout all or most of its environment. Animals become endangered for a variety of reasons. Some animals become endangered when their habitats contain resources for humans. For example, commercial forest cutting in the Amazon Rainforest has seriously reduced the population of many animal species and lead to the extinction of other groups. Land itself is an important resource to humans since it provides us with living space, and when people replace animal habitats with human habitats, it can lead to larger loss of natural species. Commercial and industrial operations may reduce land or water for animals and pollute their environment. Due to water pollution, the baiji, a fresh water dolphin native to China, was declared extinct, meaning it's unlikely the population can recover. Even noise pollution from human activities can lead to the disorder of animal behavior. Another cause that makes animals become endangered is over-fishing or over-hunting. Over-hunting whales led to near extinction of many species of whales. The introduction of a non-native species to a habitat may make animals become endangered. The native species may not defend against a new one, and the effects can be dangerous. In Australia, the introduction of the common house cat led to the extinction of the red-fronted parakeet and has seriously damaged the populations of several small animals. Introduced species can also bring new diseases with them. As a result, animals become endangered. Native animals may not have the power to fight against non-native diseases, and population levels can suffer. Another cause of disease is human-introduced chemicals. The use of DDT is believed to be one of the leading causes in driving the California Condor to near extinction. When animals become endangered, the entire food chain can be affected. For example, in 2008 disease seriously harmed the honeybee, which is largely responsible for pollinating plants, including many fruits and vegetables. Without their pollination, a very large part of the human diet could be reduced. In fact, if the honeybee should become extinct, our life would be affected and billions of dollars would be lost. Therefore, many people argue that when animals become endangered it is in man's own self-interest to protect them. The passage is mainly about _ . | [

If the item goes out of your phone's 150-foot range, it can still be found on other smart phones with the same app. When you drive the app on your phone, it shows you, with green bars that increase or decrease, how close or far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost object--a dog, for example, or a stolen bike--go out of your own phone's 150-foot Bluetooth range, you can set it as a "lost item". If any of the phones with the Tile app comes within range of your lost item, a message will be sent to your phone, telling you its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it.

mmlu_stem | mmlu_stem_11830 | Wolves travel in groups, and they perform almost all the other activities of their lives in the company of fellow wolves. This is one of the most important facts that modern science have learned about wolves and one of the things that most clearly explain their way of life. The pack is usually a family group. It is made up of animals related to each other by blood. The centre of a pack is a pair of wolves----an adult male and female that have produced young. The other members of the pack are their offspring : young wolves ranging in age from pups to two- and three-year-olds. Most packs have 6 or 7 members, although some may include as many as 15 wolves. Relationships among creatures that live close together in groups are often very complex, and this is true of the ties that connect the members of a wolf pack. Scientific studies of captive wolves and wolf packs in the wild have shown that many complex rules of behavior seem to govern the way that the animals relate to each other. When wolf pups are born into a pack, one of the most important things they must learn is the "language" of the group, the method by which pack members keep in touch with each other, sharing information and communicating their feelings. Scientists have discovered that wolves have a very complex system of communication. The most famous wolf sound is, of course, the howl, and it is a very important part of wolf language. When people think about howling, they usually imagine a sad, lonely sound made by a wolf sitting all alone on a hilltop in the moonlight. However, this picture in most human beings' mind is not completely true. Wolves howl at any time, not just at night, and they often howl together, not alone. Group or chorus howling is another means by which the members of a wolf reaffirm their ties with each other and their closeness as a group. One wolf----often the male leader----will point its nose at the sky, open its mouth, and start to howl. Immediately the other members of the pack rush to stand beside him, shoulder to shoulder, and join their voices to his. Each wolf howls on its own note so that a big chorus of slightly different sounds is produced. Chorus howling often takes place before a wolf pack goes out to hunt. At the end of a successful hunt, the pack may also celebrate with a group howl. While wolves are on the track of prey ,they are usually silent. There are occasions when a wolf will howl by itself. This may happen when an animal is separated from the pack. Pack members seem to recognize each other's voices and will keep responding to the howl of their wandering relative until the group is reunited. Because howling is a sound that carries over a considerable distance, it is very useful in communications among separated members of a pack. Howling is also used when members of different packs have to get in touch with each other to pass on information about their locations and their purposes. What most likely happens to young wolves after the age of four? | [

"They leave the pack to form packs of their own.",

mmlu_stem | mmlu_stem_4369 | A deal has been signed to turn by-products from a Scottish distillery into fuel for cars. In what is declared to be a world first, the Tullibardine distillery in Perthshire has linked up with a spin-out company from Napier University in Edinburgh. They plan to use bacteria to feed on the "leftovers" from the whisky making process. This will produce butanol which can be used to fuel vehicles. More than 90% of the stuff that comes out of a whisky distillery is not whisky. It is leftovers like draff and pot ales -- both produced in the early stages of the process. They are high in sugar and are currently used for things like fertiliser and cattle feed. Napier University's Biofuel Research Centre (BfRC) has already shown that the right bacteria can feed on those by-products to produce butanol--a direct replacement for vehicle fuel. Now the spin-out company, Celtic Renewables, and independent whisky producer Tullibardine have signed an agreement. Together they will apply the process to thousands of tons of the distillery's leftovers. Professor Martin Tangney, founder of Celtic Renewables, said "Our partnership with Tullibardine is an important step in the development of a business which combines two important Scottish industries -- whisky and renewables. This project shows that creative use of existing technologies can _ resources on our doorstep to benefit both the environment and the economy." Douglas Ross, managing director of Tullibardine, which spends PS250,000 disposing of its by-products every year, said "We are delighted to be partnering Celtic Renewables in this creative business, the obvious benefits of which are environmental. It takes a cost to us and turns it into something that has social as well as commercial value." The project is being supported by a grant from the Scottish government's Zero Waste Scotland initiative. Celtic Renewables said it eventually aimed to build a processing plant in Scotland, with the hope of building an industry that could be worth PS60m a year.

mmlu_stem | mmlu_stem_3750 | NASA on September 28, 2015 announced the strongest evidence yet for liquid water on the red planet, increasing the possibility that astronauts journeying to Mars could someday rely on the planet's own water for their drinking needs. You may feel like you've heard about the hunt for liquid water on Mars before--and the researchers involved know it may seem played out. But science has yet to truly prove that water flows on Mars once and for all, and doing so could completely change the way we view the planet. This new data is a big step in the right direction. "Liquid water is an attractive topic, and we like the thousandth time someone has discovered water on Mars," Lujendra Ojha, the Georgia Tech PhD candidate who led the research announced Monday, told The Post. But there's a good reason that liquid water is so "attractive": Mars is now the only planet in our solar system to show evidence of the stuff on its surface, other than _ . Other worlds have it in subsurface oceans, or scattered around as vapor in the atmosphere. But Mars is the only place where we have solid evidence for liquid that sits right there in the open air. While it would be a major leap to suggest that Mars might harbor life--even microbial life--liquid water at least makes it possible that parts of the planet are habitable. The study builds on research from April, when scientists using data from the Curiosity rover noted that the planet had the seasonal potential for liquid water. We know that because of the extremely low pressure on Mars, water has a boiling point of just a few degrees Celsius, after which it evaporates. The April study noted the presence of perchlorates --a kind of salt--which could make the boiling point of Mars' water much higher, theoretically allowing it to remain liquid. They affirmed that the planet's temperature would be right for liquid, perchlorate-filled water to form every day during winter and spring. The best title for the passage can be " _ ". | [

mmlu_stem | mmlu_stem_8172 | Surgeons in Spain have successfully carried out the world's first organ transplant using new stem cell technology. Some people are calling it the greatest medical breakthrough so far this century. But what are stem cells? As we know, most cells in our bodies are designed to serve specific purposes - for example, a liver cell develops to work in the liver and cannot become a heart cell. But stem cells are different. They are very young, and in the laboratory scientists can grow them into different types of cell. Claudia Castillo needed a new windpipe after getting a serious disease. Scientists from the University of Bristol in the UK took a donor windpipe, or trachea, from someone who had recently died. They used strong chemicals to remove the donor's cells, leaving a tissue scaffold . This was refilled with cells from Ms Castillo's windpipe, and stem cells from her bone. After four days the cells had grown sufficiently for the windpipe to be transplanted into Ms Castillo. Currently, transplant patients have to take drugs for the rest of their lives to prevent their bodies rejecting the new organs. These drugs can have bad side-effects, and do not always prevent rejection. But by using Ms Castillo's own cells, doctors were able to trick her body into thinking the new windpipe was her own organ. Five months on, Claudia Castillo is in perfect health. This ground-breaking procedure could be used in other transplant operations in the future. Scientists also believe stem cells might be used to treat Parkinson's disease, Alzheimer's disease, heart disease, stroke, arthritis, diabetes, burns and so on. However, stem cell research is extremely controversial. The most effective stem cells do not come from adults but from embryos created in laboratories and which are just a few days old. Many people have religious or ethical objections to growing embryos, even if they can be used to cure diseases. This transplant is considered the greatest medical breakthrough because _ . | [

The mission went perfectly without incident--at least that's what every one believed. However, that view has changed since February 22, after NASA released a digital recording of strange music heard by the space travelers.Then as they were re-entering the zone where they could communicate with ground control.One of the astronauts asked if they should report it.In response, Stafford expressed his doubts if anyone would even believe them.But they needn't have worried. When NASA experts listened to the recordings,they thought the strange sounds were radio interference. Michael Collins--the Apollo 11 pilot--said that the only reason why he was not shocked upon hearing them was that he had been forewarned by NASA officials.Collins also said that the music stopped as soon as the lunar module landed on the moon. So why did it take NASA over 40 years to release the digital recording of the awful music only after it was featured in a recent television series NASA's Unexplained Files? The US Space Agency says they have not been hiding them.In the press release that accompanies the release of the recording,NASA officials state,"The Apollo 10 audio clips were uploaded in 2012, but the mission's sound recordings have been available at the National Archives for anyone that wanted to hear them since the early 1970s." Eugene Cernan, Apollo 10's pilot who heard the sounds first,also released a statement saying,"I don't remember that incident excited me enough to take it seriously.It was probably just radio interference.Had we thought it was something other than that,we would have briefed everyone after the flight. We never gave it another thought." While most people are ready to accept this logical explanation,there are some that believe otherwise. They guess the music proves the presence of aliens. Among them is Apollo 15 astronaut Al Worden,who thinks the sounds came from a source in outer space.In the episode of NASA's Unexplained Files, which discusses the origin of the strange music,the astronaut says, "Logic tells me that if there was something recorded on there,then there was something there."

They pointed out that major college entrance tests are changing now to include a writing part. Educators know that teaching students to write well is not easy. One problem is the amount of time needed to read through large amounts of work. So some companies have developed computer programs. These can grade student writing much more quickly than a person can. Writing tests can also cost less to carry out by computer than paper-and-pencil. These computer systems are known as e-readers. They use artificial intelligence to think in a way like teachers. In the state of Indiana, computer grading of a statewide writing test began with a test of the system itself. For two years, both a computer and humans graded the student writing. Officials say there was almost no difference between the computer grades and those given by the human readers. The entrance test commonly used by business schools, the GMAT, already uses e-readers. The GRE and TOEFL tests might start; officials are deciding. The GRE is the Graduate Record Examination. TOEFL is the Test of English as a Foreign Language. Systems are also being used to grade writing in college classes. The computers read a few hundred examples of student writing already graded by humans. Then the systems compare new writings against those already examined. How do teachers feel all about this? Many say machines can never do the job as well as people can. A computer can find spelling and grammar mistakes. But these teachers say it can never really understand what a writer is trying to say. Critics say a program cannot follow a thought or judge humor or understand a beautifully expressed idea. But inventors of the programs say computer grading guarantees that each piece of writing is graded in the same way. They also say the systems are meant to judge knowledge more than creativity. Which of the following is NOT the advantage of e-readers? | [
"Saving much of teachers' time.",
"Saving a lot of money.",
"Being fair and objective.",
"Appreciating humor and beauty"

mmlu_stem | mmlu_stem_8017 | A small group of people around the world have started implanting microchips to link the body and the computer. Mr. Donelson and three friends, who had driven 100 miles from their homes in Loockport, New York, to have the implants put in by Dr. Jesse Villemaire, whom they had persuaded to do the work, are part of a small group, about 30 people around the world, who have independently put in microchips into their bodies, according to Web-based reports. At a shop William Donelson was having a four-millimeter-wide needle put into his left hand. "I'm set,"he said with a deep breath. He watched as the needle pierced the fleshy webbing between his thumb and a microchip was set under his skin. At last he would be able to do what he had long imagined: strengthen his body's powers through technology. By putting the chip inside--a radio frequency identification device (RFID)--Mr. Donelson would have at his fingertips the same magic that makes safety gates open with a knock of a card, and bridge and tunnel traffic flow smoothly with an E-Zpass. With a wave of his hand he plans to connect with his computer, open doors and unlock his car. Implanting the chip was relatively simple task but very meaningful to Mr. Doneselson, a 21-year-old computer networking student so interested in the link between technology and the body that he has data-input jacks inside his body. _ might lead to an imagined future when people can be connected directly into computers. His new chip is enclosed in a glass container no bigger than a piece of rice and has a small memory where he has stored the words "Technology". Some doctors have done the piercing in people's homes, and others have implanted chips in their offices after patients signed forms showing the fact that long-term studies have not been done on their safety. Piercers treat the implants much like any other medical operation steps, instructing people to keep the site dry, and advising them that swelling and redness should last a week. With a RFID implanted, which of the following will Mr. Donelson be able to do? | [
"Make a safety gate open with a knock of a card.",
"Make bridge and tunnel traffic flow smoothly with an E-Zpass.",
"Open doors and unlock his car with a wave of his hand.",
"Turn his body and brain directly into computers."
