mmlu_stem | mmlu_stem_1449 | Once upon a time there were three rabbits, named Winston, Chester, and Francis. Chester was a brown rabbit with large eyes. Francis was grey and white and had messy fur. Winston was black and very fat. They were very happy rabbits who loved to eat. Every day they would leave their home, cross a road, and go through a small forest to get to a meadow of grass. They loved to eat that grass. One day, Chester thought he smelled something interesting. At first he thought it might be dirt. Then he thought maybe some sort of flower. So, he asked a nearby squirrel. The squirrel's name was Acorn. Acorn said that he thought it was mushrooms. However, Francis, the smartest rabbit, went to go look, and he learned that it was actually a garden of carrots. The rabbits were all excited. They all loved carrots! They ate all the carrots.

mmlu_stem | mmlu_stem_11075 | Ashlyn Blocker could break her arm and not know it. That's because Ashlyn, 13, can't feel pain. That might sound like a cool superpower. But without pain, everyday activities can be hazardous for Ashlyn. In fact, they could kill her. When Ashlyn was born, no one knew that she couldn't feel pain. But soon there was hints that something was wrong. When Ashlyn's teeth grew in, she almost chewed off part on her tongue. Ashlyn's parents took her to doctor for tests. The doctors discovered that Ashlyn couldn't feel pain, a condition called congenital insensitivity to pain(CIPA). Fewer than 100 people in the United States have it. There is no cure. . "Sometimes it's frustrating," she admits. But Ashlyn doesn't let anything stop her from doing things she wants to do. "I just have to be careful," she says. For years, Ashlyn didn't know anyone else who had CIPA. That made it harder to deal with her condition. "I felt alone," she says. One night she dreamed that there was a camp for kids like her. In 2011, Ashly's mom made the dream come true. She started Camp Painless But Hopeless. The camp is for children who have CIPA. Every November, they and their families spend four days together. The campers get to do daring activities like rock climbing--wearing safety equipment. Someday, Ashlyn wants to be a director at the camp so she can help others who can't feel pain. In fact, Ashlyn is already helping others. Since 2004, she has let scientists study her to learn more about her condition. What they are finding out could one day help people who suffer from the same disease. That makes her feel great. "I believe there is a reason for everything, " she says, "There is a reason for me."

mmlu_stem | mmlu_stem_13604 | We are all busy talking about and using the Internet, but how many of us know the history of the Internet ? Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn't work well . If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time. At first the Internet was only used by the government, but in 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made " surfing " the Internet more convenient. Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students. The Internet has now become one of the most important parts of peoples' life. The Internet has a history of more than _ years. | [

Koalas are marsupials.This means the mother carries her baby in a pocket while it develops, similar to a kangaroo.The baby koala lives in its mother's pocket for the first six months of its life. The name "koala" comes from a native Australian word that means "no drink". The koalas get almost all their water from the eucalyptus leaves they eat.That's where they get their food too.Koalas eat only eucalyptus leaves, and only the leaves of certain eucalyptus trees.The eucalyptus trees are where the koalas live.It's also where they sleep.Koalas sleep about nineteen hours a day! Why do they sleep so much? Some people think it's because they're lazy.But koalas aren't lazy.They sleep so much because there isn't much nutrition in eucalyptus leaves.Koalas store hardly any fat, so they must save their energy.One way to do this is to move slowly and sleep a lot. After a day of sleeping they like to move around and eat just after sunset.They live alone most of the time.Koalas are very protective of their trees.If a koala sees another koala eating in its favorite tree, it might tell the other koala to leave by "barking" at it.Koalas do "talk" to each other.Besides barks, the males make a deep grunting sound.The mothers and babies talk in soft clicking sounds.If they get scared they may scream like a baby.

Tu is the first Chinese Nobel winner in physiology or medicine. Also, in 2011, she became the first Chinese person to receive the US-based Lasker Award for clinical medicine. Based on a fourth-century Traditional Chinese Medicine (TCM) text, together with her team, she managed to get artemisinin from sweet wormwood through trial and error and developed an important drug that has significantly reduced death rates among patients suffering from _ . Tu delivered a speech titled Artemisinin is a Gift from TCM to the World. She has urged more research into the benefits of traditional Chinese medicine and called for joint efforts worldwide to fight against malaria and develop more potential uses for TCM, which she called a "great treasure" with thousands of years' history and empirical knowledge. She said that by combining TCM with modem scientific technologies, "more potential can be discovered in searching for new drugs " . According to the WHO, more than 240 million people in sub-Saharan Africa have benefited from artemisinin, and more than l. 5 million lives are estimated to have been saved since 2000 thanks to the drug. Apart from its contribution to the global fight against malaria, TCM played a vital role in the deadly outbreak of SARS across China in 2003. Besides treating viruses, TCM has been most effective in diagnosing diseases, cultivating fitness, treating difficult multisource illnesses, and using nonmedical methods such as acupuncture and breathing exercises. However, TCM, which is based on a set of beliefs about human biology, is seldom understood or accepted by the West. Tu's success will bring more recognition and respect for TCM, experts say. The Western world should learn to appreciate the value of the treasures of TCM, which will lead to more basic scientific research into ancient TCM texts and ways to explore research findings worldwide.

mmlu_stem | mmlu_stem_9117 | Pessimistic,anxious and depressed people may have a higher risk of dementia ,US researchers reported on Thursday. A study of a group of 3,500 people showed that those who scored high for pessimism on a standardized personality test had a 30 percent increased risk of developing dementia 30 to 40 years later. Those scoring very high on both anxiety and pessimism scales had a 40 percent higher risk,the study showed. "There appears to be a doseresponse pattern.That is,the higher the scores,the higher the risk of dementia,"Dr Yonas Geda,a neuropsychiatrist at the Mayo Clinic in Rochester,Minnesota who led the study,said in a statement. Geda and his colleagues looked at the medical records of 3,500 men and women who lived near the clinic between 1962 and 1965. They all took the Minnesota Multiphasic Personality Inventory,a standard personality and life experience test,Geda's team told a meeting of the American Academy of Neurology in Miami. In 2004,the team interviewed the participants or family members. Those who scored higher for anxiety and pessimism on the test were more likely,as a group,to have developed dementia by 2004,including Alzheimer's disease and vascular dementia. This did not mean a person who is pessimistic could assume he or she has a higher risk of developing dementia. "One has to be cautious in interpreting a study like this,"Geda said. "One cannot make a leap from group level data to the individual.Certainly the last thing you want to do is to say,'Well,I am a pessimist;thus,I am doomed to develop dementia 20 or 30 years later,'because this may end up becoming a selffulfilling prophecy ." And there is NOT any specific way to prevent dementia,although many studies have shown that a healthy diet,exercise,keeping active in other ways,doing puzzles and other activities lower the risk. What is the passage mainly about? | [

mmlu_stem | mmlu_stem_3774 | Many people will remember the flight of the space shuttle Challenger , in June, 1993.The achievement of Sally Ride, America's first woman astronaut to fly into space, made this flight especially memorable.Students from two high schools in Camden, New Jersey, however, are likely to remember Norma rather than Sally whenever they think about the flight. Norma didn't travel alone.She brought about 100 companions along with her.Norma was an ant, a queen ant who, with her subjects, made up the first ant colony to travel into space.The ants were part of a science experiment designed by the students to test the effects of weightlessness on insects. The equipment designed by the students for their colony functioned perfectly throughout the long space trip.The young scientists and their teachers were very sad to find that their insect astronauts had all died at some point before the container was returned to the school and opened.The problem did not occur in space, but on the ground after Challenger had landed.The container remained in the desert for nearly a week before the ant colony was removed.The hot, dry desert air dried out the colony's container and the ants died from lack of moisture . The project was termed a success because it did provide useful information.Students will continue their efforts to find out exactly what went wrong.They will try to prevent the same difficulties from recurring on future missions .They don't want to be discouraged either by the death of the ants or by the $10,000 shuttle fare they will have to pay to send the next colony of ants into space.

mmlu_stem | mmlu_stem_4340 | Film cameras and digital cameras work in a similar way. Film cameras After all, a film camera is basically a light - proof box. It has a lens system to focus light onto the film at the back of the camera. Let's suppose that we are outside on a beautiful summer day trying to take a picture of the family dog. We are using a film camera. We finally get the dog to lie still. You point the camera at him. What happens? Light goes into the camera lens and hits the shutter. In other words, nothing happens yet. Now let's say that the dog looks really cute and you decide to snap a picture. What happens? When you press the button, the shutter opens for a very short period of time. A small amount of light passes through and hits the film at the back of the camera. This creates an upside-down and reversed image on the film. When you finish the roll of the film, you can take it to the photo shop to develop it and you will have a great picture of your dog! Cameras come with different lens lengths. Why does it matter? Many small cameras have shorter focal lengths, which means that there is a small distance between the lens and the place where the light focuses at the back of the camera. This gives you a large view of the area you are taking a picture of. Lenses with a long focal length show a smaller area but allow you to focus on distant objects and make them bigger. They are often called telephoto lenses. A good example of a long focus lens is one that is used by sports photographers to get photos of football players as if they were standing right beside them. Digital cameras In digital cameras, the light falls not on film but onto a sensor called a CCD (Charge Coupled Device). This digitally converts light and color into a digital information or pixels . The CCD is the heart of any digital camera and usually the most expensive part ---- depending on how good it is. In the "Film cameras" part, you fail to take the picture of the dog because _ . | [

mmlu_stem | mmlu_stem_9746 | Why don't so many Americans accept the theory of evolution? A 2001 Gallup Poll found that 45 percent of Americans agree with the statement "God created the human being pretty much in their present form at one time within the last 10,000 years or so ", while 37 percent preferred a mixed belief that "Human beings have developed over millions of years from less advanced forms of life, but God guided this process", and only 12percent accepted the standard scientific theory that "Human being have developed over millions of years from less advanced forms of life, but God had no part in this process". There are at least four reasons to make people resistant to accepting evolution. 1. The warfare model of science and religion. The belief that there is a war between science and religion where one is right and the other is wrong, and that one must choose one over the other. 2. The belief that evolution is a threat to specific religious tenets . Many people attempt to use science to prove certain religious tenets, but when they do not appear to fit, the science is rejected. 3. Misunderstanding of evolutionary theory. A significant problem is that most people know so little about the theory. In the 2001 Gallup Poll, for example, a quarter of the people surveyed said they didn't know enough to say whether they accepted evolution or not, and only 34 percent considered themselves to be "very informed " about the theory. 4. The fear that evolution degrades our humanity. Darwin revealed us to be "mere animals", subject to the same natural laws and historical forces as all other animals. Believers should embrace science, especially evolutionary theory, for what it has done to uncover the magnificence of the divinity in a depth never dreamed by our ancient ancestors. We have learned a lot in 4,000 years, and that knowledge should never be denied. Instead, science should be welcomed by all who cherish human understanding and wisdom. What is the writer's view on the evolutionary theory? | [

mmlu_stem | mmlu_stem_9624 | Flight Distance Any observant people have noticed that a wild animal will allow a man or other potential enemy to approach only up to a given distance before it escapes. "Flight distance" is the terms used for this interspecies spacing. As a general rule, there is a positive relationship between the size of an animal and its flight distance --- the larger the animal, the greater the distance it must keep between itself and the enemy. An antelope will escape when the enemy is as much as five hundred yards away. The wall lizard's flight distance, on the other hand, is about six feet. Flight is the basic means of survival for mobile creatures. Critical Distance Critical distance apparently is present wherever and whenever there is a flight reaction. "Critical distance" includes the narrow zone separating flight distance from attack distance. A lion in a zoo will flee from an approaching man until it meets a barrier that it cannot overcome. If the man continues the approach, he soon penetrates(,)the lion's critical distance, at which point the cornered lion turns back and begins slowly stalk the man. Social Distance Social animals need to stay in touch with each other. Loss of contact with the group can be fatal for a variety of reasons including exposure to enemies. Social distance is not simply the distance at which an animal will lose contact with his group --- that is, the distance at which it can no longer see, hear, or smell the group --- it is rather a psychological distance, one at which the animal apparently begins to feel anxious when it goes beyond its limits. We can think of it as a hidden band that contains the group. Social distance varies from species to species. It is quite short --- apparently only a few yards --- among some animals, and quite long among others. Social distance is not always rigidly fixed but is determined in part by the situation. When the young of apes and humans are mobile but not yet under control of the mother's voice, social distance may be the length of her reach. This is readily observed among baboons in a zoo. When the baby approaches a certain point, the mother reaches out to seize the end of its tail and pull it back to her. When added control is needed because of danger, social distance shortens. To show this in man, one has only to watch a family with a number of small children holding hands as they cross a busy street. Which of the following one can be the best title of the passage? | [

mmlu_stem | mmlu_stem_4830 | A report on a new software that enables eyes to do the typing appears in Wednesday's edition of the journal Nature. Replacing a keyboard or mouse, eye-scanning-cameras mounted on computers have become necessary tools for people without limbs or those affected with paralysis. The camera tracks the movement of the eye, allowing users to "type" on a virtual keyboard as they look at the screen. And now, researchers from the Cavendish Laboratory at prefix = st1 /CambridgeUniversitysay they have developed software that replaces the standard QWERTY keyboard layout with one that is nearly twice as efficient, more accurate and easier on the eyes. Called Dasher, the prototype program looks into the natural gaze of the eye and makes predictable words and phrases simpler to write. Any off-the-shelf camera capable of scanning eye movement can be used with Dasher, though the person must sit fairly still during the interaction. The letters of the alphabet appear in a single column on the right of the screen, with an underline symbol to represent a space. Each letter is framed by a color1ed box. As the user looks at a particular letter on the right side of the screen and drags it to the left with their eye, another sub-alphabet column begins to emerge inside the box on the right-hand side, along with more letters framed in color1ed boxes. Dasher is designed to anticipate which letter will be needed, so although the successive sub-alphabet columns are initially very small, the letters or combination of letters that appear are most likely to be used next in that sequence. For example, if a person starts with the letter "h", the language models in Dasher will bring up "a" "e" "i" "o" and "u" in the sub-alphabet box, along with a few other possible combinations like "ello" to form the word "hello". Each box has a complete alphabet within it, though the first letters to appear have the highest probability of usage. The letters are then placed together to form a sentence on the left side of the screen. Researchers say people will be able to write up to 25 words per minute with Dasher compared to on-screen keyboards, which they say average about 15 words per minute. With a bit of practice, MacKay said, Dasher offers an easier and more satisfying way for disabled people to communicate, providing them with better tools to write e-mail or create word processor files. Mackay said Dasher could work in most languages. Which of the following is true about Dasher? | [
"It can be used to write ten more words than on screen keyboard per minute.",
"It is easier to use than ordinary keyboards.",
"It can provide hints for possible sentences to be written.",

They have eight players for each team, while we may have the match between two sides with equal men or women players. Of course, they are usually tall, strong and heavy. For a tug-of-war match, we need a long thick rope. Each team stands at one end of the rope, holding it. Then they try to pull the center of the rope, marked in the ground towards each of their own sides. The team which succeeds in pulling the center of the rope away through a certain distance is the winner. Many foreign sport experts think we don't have to be tall, heavy and strong to play tug-of-war. We needn't have endless energy, for a match lasts only a few minutes. The secret is good hands. The players must have big, strong and hard hands. Before they start the match, they put a mixture of oil and petrol on their hands so they can hold the rope better.

Unlike dogs, which generally wave their tails to express good feelings, cats use their tails to send a lot of signals. When a cat waves its tail strongly from side to side, it may be a sign for us to leave it alone, or we may get scrathed . Throwing a little toy for the cat to play with can get it relaxed. When a cat holds its tail upwards with a slight move, it means the animal is very happy to see its owner. We all like to cuddle inside our bed, and cats do that thing, too. Much as little children like to wrap (......) their arms around their Teddy Bears, cats like to wrap their own tails around their bodies to get a sense of safety while asleep. If we notice a cat sleeping in such a position, we should not break its peace. Usually the tip of the cat's tail doesn't draw our attention. But its particular position may also show the cat's feelings. For example, a cat holding the tip of its tail pointed downwards may try to say that it is not feeling comfortable. So at this point, the cat not only feels angry, but also unsafe. This may again be a sign for us not to upset the cat in any way.

mmlu_stem | mmlu_stem_4964 | Getting too little sleep or not spending enough time in rapid eye movement(REM) sleep is connected with being overweight among children, according to a new study. For three nights, researchers studied the sleep patterns of 335 young people, aged 7 to 17. They looked at total sleep time, time spent in REM, time it took to fall asleep. Body-mass index was checked at the start of the study, and 45 persons in the research were overweight, while 49 were at risk of becoming overweight. Compared to normal-weight children, those who were overweight slept about 22 minutes less per night and didn't sleep as well as them, which means shorter REM sleep, less eye activity during REM sleep, and a longer wait before the first REM period. After more research, the researchers concluded that one hour less of total sleep was connected a double increased risk of being overweight. One hour less of REM sleep was connected with a three times increased risk. Although the reasons are still being researched, the relationship between short sleep duration and overweight may be the result of behavioral and biological changes, which are caused by sleep loss, wrote Dr. Xianchen Liu of the Western Psychiatric Institute and Clinic in Pittsburgh and his colleagues. They explained that sleep loss causes changes in hormone levels that may have an effect on hunger, and less sleep also means a person has more waking hours in which to eat. Sleep loss also leads to tiredness the following day, which may lead to less physical activity and fewer calories burned. What is the best title for this passage? | [

mmlu_stem | mmlu_stem_10789 | Watching a child struggle to breathe during as asthma attack is frightening for any parent. So it is only natural that most moms and dads will try just about anything, including spending a lot of money -to keep an attack at bay. Trouble is, more than half of parents are trying strategies that simply do not work and wasting hundreds of dollars in the process. According to Dr. Machael Cabana, a pediatrician at the prefix = st1 /UniversityofMichigan's C.S. Mott Children's Hospital, who led the study, one of the most common mistakes was to buy mattress cover to protect against dust mites for a child whose asthma instead was made by plant pollen . Many of those parents then neglected to do what would have helped a lot more; shut the windows to keep pollen out. Another was using a humidifier for a child who was allergic to dust mites; a humidifier tends to be a place where dust mites like to breed. With those allergies, a dehumidifier works better. Worst of all was the number of smokers with asthmatic children who didn't even try to quit or at least limit themselves to smoking outdoors rather than just moving to another room or the garage. Many smoking parents purchased expensive air filters that have what Cabana called " questionable utility. " Part of the problem, Dr. Caban and his colleagues believe, is that parents are bombarded by television ads that encourage them to buy products such as air and carpet fresheners, ionizers and other remedies that are often expensive but medically unnecessary. And doctors may not always take the time, or have the time, to explain to parents what will and won't work in their child's particular case. For example, allergies are usually a problem for older children with asthma, while kids 5 and younger more frequently have trouble with viral repiratory infections. So make sure you understand what the cause of your child's asthma really is. The intended readers of the passage are _ . | [

mmlu_stem | mmlu_stem_15086 | If you want to watch and know something about birds, you must find a good place near the bird nest . Birds sit on eggs and take care of their babies from April to June. Because the baby birds are too young to leave the nest, parents often go to look for food and come back in several minutes. So it is good to watch birds. When we watch birds, we'd better hide ourselves in a close place to the nest, and it's better to use binoculars . But how to make a bird nest? A good bird nest must be very fine, strong, thick and comfortable. If you want to make one, please follow these: a) Each nest must have six boards . Don't make the boards too slippery . b) Dig a small hole in the front of the nest as a "door". The "door" is big enough so birds can fly in or out easily. c) Make sure the rainwater can't go into the nest. d) One piece of the board should be easy to open. e) Don't forget to color the nest. We have to hide ourselves to _ when we're watching birds. | [

Now scientists are lending a hand, developing tomorrow's super-powered clothing such as coats that can recharge your MP3 player and make you stronger. For example, electronics could get recharged in the future simply by plugging them into your outer wear, because Australian researchers are designing clothing that can collect energy from a person. The coats would include small things that change vibration energy from a person's movements into electricity. High-tech fabrics would carry this energy to batteries . "It will look like an ordinary(common)coat but have super energy," said Adam Best, an Australian head research scientist. " _ has important uses for soldiers in the field and could mean they no longer need to carry heavy batteries,'' Best added. "Above all, they'd be wearing the battery, not carrying it." Besides helping soldiers, these coats could also have common uses for common people, such as powering radios, mobile phones, MP3 players or medical things. Solar-powered handbags could do the same thing. Thanks to self-cleaning fabrics developed by scientists working for the U. S. Air Force, underwear and sports clothing could go weeks without washing. The general idea of clothes that never get dirty can be found in the 1951 film The Man in the White Suit. The new technology helps keep off water, oil and bacteria . High-tech fabrics could also help serve as protection. For example, future fabrics could lead to soft helmets that turn hard in an accident. Not all the possible fabrics of tomorrow are necessarily high-tech. For example, chicken feathers and other things of the farming industry could get changed into wool-like fabrics or cotton-like ones, helping use fewer fabrics made from oil. Scientific development is also creating wool that doesn't become bigger or smaller after washing. And future clothing could help soldiers shoulder heavy bags and help people walk. But not all electronic coats have such uses--some might serve as video game players with high technology and the latest fashion joined together perfectly.

While details about how and why the former paratrooper became attached to these beautiful wild animals are a little summary,he has been tending them in his 25acre Wolvespark located in the German province of Saarland,since 1972.While he currently has a group of 29,over the years he has raised almost 70 wolves belonging to all breeds ranging from Siberian to Arctic,Canadian,European and even,Mongolian.The wolves treat Werner as if he were one of their own.They nuzzle against him,play with him and are generally sheeplike when he is around,just like they would be around a head wolf! This,however,is not accidental-It is a position that Werner works on establishing and maintaining with a simple act,every single day-Whenever it's feeding time,he calls his wolves to come for the raw meat by howling.As the hungry animals rush to get their food,they are always met with this scene-Werner sinking his teeth into the raw meat first.While this may sound a little rude,that is how the position of hierarchy is established in the animal world.It is always the leader male that gets the first meal and only when he signals,can the rest join in.Werner's wolves know this rule quite well and never challenge his authority.

mmlu_stem | mmlu_stem_10342 | Computer technology has become a major part of people's lives. This technology has its own special words. One example is the word mouse. A computer mouse is not a small animal that lives in buildings and open fields. It is a small device that you move around on a flat surface in front of a computer. The mouse moves the pointer on the computer screen. Computer expert Douglas Engelbart developed the idea for the mouse in the early 1960s. The first computer mouse was a carved block of wood with two metal wheels. It was called a mouse because it had a tail at one end. The tail was the wire that connected it to the computer. Using a computer takes some training. People who are experts are sometimes called hakers. A hacker is usually a person who writes software programs in a special computer language. But the word hacker is also used to describe a person who tries to steal information from computer systems. Another well-known computer word is Google. It is the name of a popular "search engine" for the Internet. People use the search engine to find information about almost any subject on the Internet. The people who started the company named it Google because in maths, google is an extremely large number. It is the number one followed by 100 zeros. When you "Google" a subject, you can get a large amount of information about it . Some people like to google their friends or themselves to see how many times their names appears on the Internet. If you Google someone, you might find that person's name on a blog. A blog is the shortened name for a Web log. A blog is a personal Web page. It may contain stories, comments, pictures and links to other Web sites. Some people add information to their blogs every day. People who have blogs are called bloggers. Blogs are not the same as spam. Spam is unwanted sales messages sent to your electronic mailbox. The name is based on a funny joke many years ago on a British television show, " Monty Python's Flying Circus". Some friends are at an eating place that only serves a processed meat product from the United States called SPAM. Every time the friends try to speak, another group of people starts singing the word SPAM very loudly. This interferes with the friends' discussion---just as unwanted sales messages interfere with communication over the Internet. What do we know about hackers? | [

Recently, scientists at Indiana State University have discovered that ducks sleep this way too. They found that ducks sleep half awake so they can rest and watch for danger at the same time. After putting their ducks in a row and videotaping them, some researchers found ducks on the end of each row spent more time asleep with one eye open, apparently looking for _ "The more the ducks felt threatened, the more they slept with one eye open," said lead author Niels C. Rattenborg, a graduate student at Indiana State University, Terre Haute. "The unique aspect is not that they do it, but that they control it. When they sleep at the edge of a group, they tend to realize greater danger, so they spend more time sleeping with one half of their brain." Ducks with one eye open were still awake enough to detect predators, said the authors of the study, which appears today in the journal Nature. The researchers studied four groups of four ducks held in plastic boxes, which were arranged in a row. Ducks on the end were found to sleep with one eye open 31.8 per cent of the time, compared to 12.4 percent of the time for ducks in the central position. Also, ducks in the central position did not open one eye more than the others, while ducks on each end kept the eye facing away from the group open 86.2 per cent of the time. Brain wave readings of the ducks showed that the half of the brain receiving signals from the closed eye indicated that half of the brain was sleeping.

mmlu_stem | mmlu_stem_9028 | Mr. Sankaram, a physics teacher, was known for his antics in his classroom to make the dull lessons in physics lively and interesting. Mixing different chemical drugs in the lab to become new substances in chemistry makes students excited. While studying botany or zoology, students can visit a garden or zoo. But physics limits students to listening to the boring lectures which are hard to understand. For example, why an apple dropping from a tree travels downwards but not upwards. But Mr. Sankaram's classroom antics to cause students to listen to topics such as how sound travels in air or why light travels faster than sound made him stand out from the rest of the teachers. At that time, most students in our school attended the college to please their parents, and some parents were proud of their children for simply attending a college, no-matter whether they benefited or not. They didn't study hard. But a few students were diligent and they wanted to study pre-medical courses to gain admission into the medical school. The schooling of pre-medical courses was very expensive. The college was next to the medical school. The wall separating them was about four feet high. Few tried to jump over the wall to get free pre-medical courses. Doing this was at risk of injuries and the climbing was forbidden. The college where Mr. Sankaram taught was known for unruly and naughty students. The unruly students usually sat at the back of the classroom. When a student from the back of the classroom tried to disrupt the class, Mr. Sankaram would say, "Dare you go ahead to make noise? Can you jump over the four-foot wall to get into the medical school?" The student's face went red and he became silent. In the physics class . I sat in the first row to escape from the troublemakers at the back. One day during the class. Mr. Sankaram unexpectedly asked me, "Can you jump over the four-foot wall?" I shook my head and answered, "No, sir, I couldn't jump over a one-foot wall, let alone a four-foot wall." Mr. Sankaram wasn't satisfied with my reply but waved his hand for me to sit down. He looked at me in the eyes hard and said, "If you can. Believe in yourself!" There were stories about Mr. Sankaram's past history. As a student at same college years ago, he went into much depression for some time when he couldn't get into the medical school. In fact he could have been admitted by the school by his ability of studying. Because his family couldn't afford his pre-medical courses and he didn't dare to climb the wall, he often walked back and forth along the four-foot wall talking to himself and sometimes cried over his failure. Whether this story was true or false it was passed on from year to year. So Mr. Sankaram had a nickname "four-foot." It was true that he left his dream to his students and he began challenging the students' ability to jump over the four-foot wall to get into the medical school. As a student I failed at my attempt to get admission into the medical school. In fact not all students wanted to be a doctor. And years later I ended up as a chemistry teacher at the same college. I thank Mr. Sankaram for his encouragement to me, and I am determined to follow his example to make my class interesting. Mr. Sankaram passed away years ago. He will always be remembered for his wonderful teaching techniques such as dancing movements and his encouraging words. Mr. Sankaram's failing to get into the medical school _ . | [

mmlu_stem | mmlu_stem_2654 | Swimming in the water of Hawaii's Big Island is a fun experience. But it can be more exciting if there are dolphins swimming around and jumping out of the sea too. For many people, it would be a wonderful dream to swim with these lovely animals! However, this may not be good for dolphins. They may get hurt because of human interaction . Dolphins are active and usually look for food at night. In the day, they like to rest in shallow bays . Many people think the dolphins are awake during the day as they swim. But when they sleep they rest half of their brain and keep the other half awake to breathe, so they may be sleeping even when they're swimming in the water. From 2010 to 2013, spinner dolphins of Hawaii's Big Island were exposed to human activities more than 82 percent of the time, according to Julian Tyne, a researcher at Australia's Murdoch University. The National Oceanic and Atmospheric Administration (NOAA) says disturbing the animals in their near-shore habitat could force them to swim to less favorable places, putting them at risk of attack by sharks and other animals. Besides, when people are around, dolphins become more active. Thus, they can't get enough sleep. "Disturbing their resting behaviors can actually affect their long term health and the health of the dolphin population," Ann Garrett of NOAA's National Marine Fisheries Service told the Associated Press. As a result, the NOAA wants to make rules to help protect the dolphins. For example, the agency may ban swimming with the Hawaii spinner dolphins. Or they may stop people from swimming in shallow bays when the dolphins are resting. Tour operators must also be taught to watch for signs to know when the dolphins are in their resting state.

On March 9, 2011, after returning from its final voyage, the world's most traveled spaceship was retired. A crowd of shuttle workers, reporters and schoolchildren waited to greet Discovery at Kennedy Space Center in Cape Canaveral, Florida. Three minutes before noon, they watched as the shuttle appeared in the sky and made one last touchdown. "For the final time: wheels stop," Discovery's commander Steven Lindsey said when the shuttle rolled to a stop. Discovery's final trip was to the International Space Station (ISS), a giant space lab in the sky. Discovery's crew took care of the last U.S. construction project at ISS. They delivered 10 tons of supplies for the ISS. The six-person crew also dropped off an unusual companion for ISS's researchers: a human-like robot named Robonaut 2. Astronauts will assemble R2 at the ISS over several months. Now, NASA is its shuttle programme. NASA is to begin work on new spaceships that can travel longer distances.

Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners _ . Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow "lost or stolen" sign appears on its screen when it is started.

"One customer sent a message saying, 'You are being tracked. I am right at your door'," said Carrie Hafeman, chief executive of the company which produces the program, Retriever. In the latest version, people can add a spoken message. For example, the laptop's speakers will say: "Help, this laptop is reported lost or stolen. If you are not my owner, report me now." The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password immediately if they fear that the thief has also got hold of the access (, ) details. If a thief accesses the Internet with the stolen laptop, Retriever will collect information on the Internet service provider in use, so that the police can be alerted to its location.

Some of the school's students had visited Cancun on a spring break trip two weeks ago. Officials reported 68 U.S. cases of swine flu in five states so far, with the latest in Ohio and New York. Unlike in Mexico, cases in the United State have been mild and U.S. health authorities can't yet explain why. In New York City, Centers for Disease Control and Prevention confirmed that there were 45 cases, Mayor Michael Bloomberg said. About 100 students at St. Francis Preparatory School complained of flu-like symptoms; further tests will determine how many of those cases are swine flu. St. Francis is the largest private Catholic high school in the nation, with 2,700 students. The school canceled classes on Monday and Tuesday in response to the outbreak. Bloomberg stressed that the New York cases were mild and many are recovering, but said that some family members of students also had flu symptoms. In Mexico, health officials say a strain of swine flu has killed up to 160 people and sickened over 2,000. New York officials said the flu strain discovered in the patients here is the same strain as in Mexico, though all the New York cases are mild. Swine flu is a respiratory disease of pigs caused by type A flu viruses. Human cases are uncommon but can occur in people who are around pigs. It also can be spread from person to person.

mmlu_stem | mmlu_stem_6738 | Risk of death is 3.5 t0 5 times greater for obese smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine. The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 t0 92 questions about age, height, weight and smoking behavior. BMI (body mass index) was calculated, with a BMI of 30 t0 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred. The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists. Key Findings: 20 percent of obese adults in the United States smoke. Obese smokers face a greater risk of death from cancer and circulatory disease. Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking. The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death. Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts. While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today. Taking Charge of Your Health Making healthy choices can be difficult when we're constantly bombarded with products that are hazardous to our health, but it's not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you're an overweight smoker worried about gaining weight due to quitting, take heart.

Albert Stunkard of the University of Pennsylvania found from experiments that"80 percent of the children of two fat parents become fat,as compared with no more than 14.percent of the children of two parents of normal weight." How can obese people become thinner through dieting? Well,dieting can be effective.but the health costs are great. Jules Hirsch,a research physician at Rockefeller University,did a study of eight fat people.They were.given a liquid formula providing 600 calories a day.After more than 10 weeks,the subjects lost on average 45 kg.But after leaving the hospital,they all regained the weight.

But months after the study ended,they were back to normal weight and stayed there. This did not mean that people are completely without hope in controlling their weight.It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly 1ower their weight. The findings also provide evidence for something scientists thought was true--each person has a comfortable weight range.The range might be as much as 9kg.Someone might weigh 60--69kg without too much effort.But,going above or below the natural weight range is difficult.The body resists by feeling hungry or full and changing.the metabolism to push the weight back to the range it seeks.

mmlu_stem | mmlu_stem_11663 | When Lady Gaga releases a new, pleasing and easily remembered single, it quickly goes around the world. Now scientists have discovered the same thing happens with the songs of another creature----the humpback whale. The mammals become absorbed by new tunes just like people do, and the most popular original whale songs spread globally like hit singles. Male humpback whales are famed for the loud, long and complicated songs they make during the mating season. Each song lasts for 10 to 20 minutes and the males can sing nonstop for 24 hours. At any one time, all the males in a population sing the same song. But a study shows that this song changes over time and spreads around the oceans. Dr. Ellen Garland of Queensland University, said: "Songs move like cultural communication from one population to another, causing all males to change their song to a new version." Researchers recorded songs from six neighboring populations of whales in the Pacific over a decade. They found that new versions of the songs appear over time and always spread from west to east. It takes two years for songs that appear in the waters off Australia to be heard in French Polynesia. Most of the new songs contain material from the previous year mixed with something new. " It would be like getting an old Beatles song together with U2," she said. " Occasionally they completely throw the current song out of the window and start singing a completely new song". Dr. Garland believes that a small number of whales may migrate to other populations carrying the new songs with them, or that they are heard by passing whales. The researchers suspect whales adopt new songs to make themselves distinct. Dr. Garland said: " we think this male search for new songs is in the hope of being that little bit different and perhaps more attractive to the opposite sex." According to the text, male humpback whales sing new songs to _ | [

The machine will recycle everything from sweat , the water for washing hands, shower water, water used for brushing teeth, and even urine, to make drinking water. It will save NASA millions of dollars each year. At present, each ISS astronaut uses about 4.4 liters of water every day. It costs about $24 million a year to transport water up to ISS. NASA says that a liter of water costs about $11,000. The machine will be sent to the ISS in October 2008. NASA hopes it will recycle about 93% of all water used on the station. Will the water be clean? Scientists say the wastewater will go through a very complicated process . For example, different chemicals will be put in the wastewater; the water will be heated to 130degCto get rid of bacteria .

mmlu_stem | mmlu_stem_5671 | It's not quite a rat. Nor is it a squirrel, or a mouse. It's definitely a rodent , and it's also a brand-new family of mammals. The locals of the Southeast Asian country of Laos call the creature a kha-nyou (ga-nyou). The kha-nyou have long body hair, short legs, and a hairy tail less thick than a squirrel's. They're vegetarians living in the rocky hills of Laos, and they come out at night, but for more information, you'll have to ask the Lao people. "It was for sale on a table next to some vegetables. I knew immediately it was something I had never seen before," said Robert Timmins, a researcher for the Wildlife Conservation Society. Timmins was working in Laos to stop people from selling endangered animals when he spotted the species. Criminals who trade illegal wildlife can make a lot of money, but they also push the animals closer to disappearing from the planet. The kha-nyou live in karsts, or rough rock. Mark Robinson, a scientist with the World Wildlife Foundation, set out with Lao villagers to find a few more of the rodents for study. They climbed onto a karst, trapped with rice, and caught several. "To find something so unusual in this day and age is just extraordinary," said Timmins. "For all we know, this could be the last remaining animal family left to be discovered." It's a big deal to discover an entirely new family of animals. Humans, for instance, belong to the same family as great apes, chimpanzees, and gorillas. So even though kha-nyous look like rats, they're really very different. The last time scientists discovered a new family of mammals may have been in the 1970s, when they found new bats in Thailand. Timmins seems to have the gift for finding new animals in Laos--he discovered a new species of rabbit there in 1999. Scientists call the kha-nyou Laonastes aenigmamus, which means "mysterious mouse that lives among the stones."But if that's too hard, Timmins and Robinson suggest you call them "rock rats".

The volcano, called Mount Vesuvius, formed 25,000 years ago. During its most explosive eruptions, the volcano could blanket nearby cities with hot ash, sometimes also burying them with deadly flows of mud and rocks. One famous eruption occurred nearly 2,000 years ago, in the year AD 79. It lasted 18 hours and destroyed the Roman cities of Pompeii and Herculaneum, killing thousands of people as they tried to escape. Scientists and city officials had supposed that Naples, one of Italy's most populous cities, was far enough away that it would be safe from the volcano's _ . New evidence suggests that this might not be the case. Researchers recently discovered 4000-year-old layers of ash and mud under present-day Naples. Just outside the city, they also uncovered abandoned villages, as well as human and animal skeletons. Most surprising of all, the researchers say, was the discovery of thousands of footprints from the same time period, pressed into layers of wet ash that had rained from the sky. The footprints show that thousands of people were fleeing to the northwest, away from the volcano, as it erupted. Mount Vesuvius hasn't had a major eruption since 1631, but it's still very active. The discovery of the ancient ash layers, skeletons, and footprints is a warning that modern Naples, a city of 3 million people, isn't safe from the volcano, scientists say.

mmlu_stem | mmlu_stem_4279 | The high noise of modern life may affect speech and language development in the very young, according to a study that found the auditory parts of the brains of young mice are slower to organize properly in the presence of continuous sounds. Researchers at the University of California, San Francisco, reared a group of rats in an environment of continuous background noise and found that their brain circuits that receive and interpret sound did not develop at the same rate as animals that were raised in a quieter environment. Edward F. Chang and Michael Merzenich, co-authors of the study appearing in the journal Science, said that the continuous noise delayed the organization of auditory neurons during a critical two-to-three-week period after the rat pups were born. For rats not exposed to the noise, the auditory cortex neurons during this period gathered into a smaller area and began developing a selective response to sounds. But for the noiseexposed rats, this organization was slowed, causing a delay in the development of the ability to discriminate specific sound tones. The researchers said it took three or four times longer for the rats raised in a noisy environment to reach the basic bench marks of auditory development seen in the rat pups not exposed to noises. Although the rat is not a perfect model for what happens in humans, the authors note, the study does suggest that high levels of noise might possibly affect some language learning in babies. "These findings suggest that environmental noise, which is commonly present in contemporary child-rearing environments, can potentially contribute to auditory and language-related development delays,"the authors wrote in Science. The authors noted that although the brain development was delayed in rats exposed to the noise, their brains did eventually mature normally.

The story of the young British naturalist Charles Darwin combines both of these. That is why the author and illustrator Rosalyn Schanzer chose to write the children's book "What Darwin Saw". The book was published just in time for the 200th anniversary of Charles Darwin's birth on February 12, 1809. Rosalyn Schanzer carefully gathered Darwin's thoughts and observations from his diaries, letters and books. Many of the words in the book are Darwin's own. She also traveled to the Galapagos Islands and South America. She researched some of the places Darwin had visited on his trip on the ship, the Beagle in the 1830s. She took thousands of pictures, which helped her create the book's beautiful and color1ful drawings. These pictures show young readers what led Darwin to form his great discovery: the evolution of species through natural selection. "What Darwin Saw" tells of the adventures of a young man who traveled around the world as a scientist. The voyage of the Beagle took Charles Darwin to South America, where he rode horses with cowboys and met Native Americans in Argentina. He reported the eruption of the Osorno Volcano and experienced an earthquake in Chile. Darwin's observations showed him that environments can change very quickly and a great deal over time. Rosalyn Schanzer brings to life the clues that suggested to Darwin that living things evolve, or change, over time. She illustrates the unusual tortoises, birds and lizards that Darwin studied in the Galapagos Islands.

mmlu_stem | mmlu_stem_9495 | MELBOURNE, Australia - A kangaroo frightened by a man walking his dog attacked the pair, throwing the pet underwater and hitting the owner in the stomach with its back legs. The Australian, Chris Rickard, was in stable condition Monday after the attack, which ended when the 49-year-old struck the kangaroo in the throat. Rickard said he was walking his blue dog, Rocky, on Sunday morning when they surprised a sleeping kangaroo in Arthur's Creek northeast of Melbourne. The dog chased the animal into a pond, when the kangaroo turned and knocked the pet underwater. When Rickard tried to pull his dog free, the kangaroo turned on him, attacking with its back legs and tearing a deep cut into his stomach and across his face. "I thought I might take action to drag the dog out from under his grasp, but I didn't expect him to actually attack me," Rickard, 49, told The Herald Sun newspaper. "It was a shock at the start because it was a kangaroo, about 5 feet high, they don't go around killing people." "I was stuck having to hold on to the dog with both hands because it was half drowned and I couldn't really see anything because the kangaroo just attacked me." He added, "All I could do was just keep pushing for the bank and he was trying to push me under the water, so at that point I struck him in the throat and that made him back off a little bit. "I don't think I'll ever be able to watch kangaroo programs quite the same as I used to -- it might bring back a couple of bad memories." Kangaroos rarely attack people but will fight if they feel threatened. Dogs often chase kangaroos, which have been known to lead the pets into water and defend themselves there.

The parents of Tim Berners-Lee both worked on one of the earliest commercial computers and talked about their work at home. As a child he would build models of computers from packing material. After graduating from Oxford University he went on to the real thing. In the 1980s, scientists were already communicating using a primitive version of e-mail. While working at a laboratory in Switzerland, Tim Berners-Lee wrote a program, which let him store these messages. This gave him another idea: write a program that will let academics from across the world share information on a single place. In 1990 he wrote the HTTP and HTML programs which form the basis of the World Wide Web. The next year his programs were placed on to the Internet. Everyone was welcome to use them and improve them if they could. Programmers used this codes to work with different operating systems. New things like web browsers and search engines were developed. Between 1991 and 1994 the number of web pages rose from 10 to 100,000. In 1994 Tim Berners-Lee formed the newly formed World Wide Web consortium , or W3C. More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone can share equally on the web.

Recently more and more hospitals and clinics have been _ the power of music -not only to comfort patients, but to help cure them as well. Welcome to the world of music therapy . After each of the two world wars, musicians visited hospitals and played instruments for injured soldiers suffering from emotional and physical pain. Today's music therapists continue this practice, playing instruments such as guitars and harps to bring comfort to their audiences. Therapist Eric Mammen encourages his patients at a children's hospital to participate with him as he plays. During visits with 13-year-old cancer patient Lawrence Garcia, Mammen encourages Garcia to beat on electric drums while he plays the guitar. The therapy won't cure his cancer, but it does, according to Garcia's mom, take away much of the boy's depression . Music therapy can put patients in better moods and ease the symptoms of depression according to the American Music Therapy Association. Other benefits include relieving pain, calming tension, aiding sleep, reducing worry or fear, and easing muscle tension. Jose Haro personally experienced the benefits of music therapy when he was recovering from heart surgery. During his recovery, he played a piano whose keys lit up, indicating which keys to touch to play along with the background music. Soon he was playing tunes and noticing something strange. "I was searching for my pain." He says of his experience, "but it was gone." While Haro's experience provides an evidence of the power of music to relieve pain, scientific research has proven music also helps patients with Alzheimer's disease and arthritis. In addition, music therapy helps premature babies. Doctors are tapping into a powerful way to teach premature babies that haven't yet learned how to suck. Doctors use a device that comforts the babies by playing music when they suck on a pacifier . Soon the babies learn to suck in return for music, gaining weight faster and going home earlier than those who do not use the device. Even perfectly healthy people are discovering the power of music to calm and heal. Drum circles attract people who find stress relief in beating out rhythms. While music is not a cure-all, it does make life a little easier. What is the best title for this passage? | [

Because the baby birds are too young to leave the nest, mothers often leave and come back to the nest during the time to look for food. So it is good to observe birds. When we observe birds, we'd better hide ourselves in a close place to the nest, and it's better to use binoculars . But how to make a bird nest? It's very easy. If you want to make one, please follow these: Making a nest: A good nest must be very fine, strong, thick and easy. a) Each nest must have six boards. Don't make the boards too slippery. [:Zxxk.Com] b) Dig a small hole in the front of the nest as a door. The "door" is from 3cm to 5cm. So the bird can fly in or out easily. c) Make sure the rainwater doesn't go into the nest. d) One piece of the boards should be easy to open. e) Please don't forget to color the nest.

Children usually choose certain foods above the others and often do not eat those with important nutrients . Sothough the food they are eating is nutritious, it may not always provide all the nutrients the child needs. One nutrient can not balance the shortage of another. Foods like grains, vegetables, fruits and meats should be eaten daily, because different foods in the child's diet can balance against taking too much or too little of any nutrient. Kids grow slower in their childhood than when they were babies or when they develop into adults. Energy output is high, with hard paly perids that include plenty of running, jumping, and testing of new physical skills. So they need a lot of vitamins. Here are some important vitamins and their functions Vitamin D in milk helps your bones. Vitamin A in carrots helps you see at night. Vitamin C in oranges helps your body heal if you get a cut. B vitamins in leafy vegetables helps your body make protein . The children, who are suffering from a sickness called cystic fibrosis, lose vitamin A, D and E. These are main body-building vitamins. Therefore, vitamin supplements may be necessary. Blood tests will telll you whether a child needs vitamin supplements. If babies over nine months of age are receiving whole cow's milk, they'll need a daily vitamin C supplement till their diet provide enough vitamin C. Vitamin D is added to all milks so babies drinking them need no extra vitamin D. Children are greatly in need of vitamin C. If you are 18 years of age or younger, you should get 115 millgrams of vitamin C per day. Those over 19 should get 120 milligrams per day. When do kids have to take a vitamin supplement? | [

Take bladderworts, a kind of such plant, for example. They appear so small and grow in a quiet pond. "But these are the fastest known killers of the plant kingdom, able to capture a small insect in 1/50 of a second using a trap door!" Once the trap door closes on the victim, the enzymes similar to those in the human stomach slowly digest the insert. When dinner is over, the plant opens the trap door and is ready to trap again. Meat-eating plants grow mostly in wet areas with soil that doesn't offer much food nutrition. In such conditions, these amazing plants have developed insect traps to get their nutritional needs over thousands of years. North America has more such plants than any other continents. Generally speaking, the traps may have attractive appearance to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers full of nectar . Hair-like growths along the pitcher walls ensure that nothing can escape, and the digestive enzymes can get to work. A tiny insect can be digested in a few hours, but a fly takes a couple of days. Some of these pitchers are large enough to hold 7.5 liters. Meat-eating plants only eat people in science fiction movies, but sometimes a bird or other small animals will discover that a pitcher plant isn't a good place to get a drink.

But, they can also cause a lot of problems, send you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two. Barry Brown is with the Mobile Life Centre in Stockholm, Sweden. The center studies human-computer interaction, or HCI, especially communications involving wireless devices. He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay. "And they just plugged in an address and then set off to their destination. And, then it wasn't until they were driving for thirty minutes until they realized they actually put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of 'garbage in garbage out'." Mr. Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment. "One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place."

mmlu_stem | mmlu_stem_8188 | A villa designed to resist earthquakes with "self-healing" cracks in its walls, thanks to nanotechnology applications with self-healing polymers , is to be built on a Greek mountainside. The villa's walls will include special particles that turn into a liquid when squeezed under pressure, flow into cracks, and then harden to form a solid material. The NanoManufacturing Institute (NMI), based in Leeds University, will play a key role in an EU project to construct the home by December 2010. The project, called "Intelligent Safe and Secure Buildings" (ISSB) is funded under the EU's Sixth Framework program. This potentially life-saving scheme is led by German building manufacturer Knauf. The villa will be built in Amphilochia, in western Greece, where Knauf currently runs a manufacturing plant. If the experiment is successful, more tremor-resistant homes could be built in earthquake zones across the globe. NMI chief executive Professor Terry Wilkins said, "What we're trying to achieve here is very exciting. We're looking to use polymers in much tougher situations than ever before on a larger scale." Monitors contained in the villa's walls will be able to collect vast amounts of data about the building over time. Wireless sensors will record any stresses and vibrations, as well as temperature, humidity and gas levels. The walls are to be built from new load-bearing steel frames and high-strength gypsum board. Prof Wilkins said, "If there are any problems, the intelligent sensor network will be able to alert residents immediately so they have time to escape. If whole groups of houses are so constructed, we could use a larger network of sensors to get even more information. If the house falls down, we have got hand-held devices that can be used over the ruins to pick out where the embedded sensors are hidden to get some information about how the villa collapsed. Also, we can get information about anyone who may be around, so it potentially becomes a tool for rescue." The villa can resist earthquakes because _ . | [

Larger male chimps drop from the trees to face the threat while the others climb to safety. Then the dogs' young human masters appear. One mother chimp with a tiny baby tries to run. The dogs attack and separate them. The two teenage boys quickly catch the baby chimp. But they don't act out of sympathy --- they save the baby so they can sell it. After the teenagers return to their hometown, they visit a man who is said to be very interested in chimps. When they ask the man, Johnny Kante, if he wants to buy the baby, he replies, "That's not what we do." Kante is a member of a scientific team. Although Kante is angry with the teens for capturing the chimp, he hides his anger and persuades them to take him to the baby chimp. Unsure of what to do next upon seeing the chimp, Kante calls Jill Pruetz, the head of the chimp research team. "I'm really worried," says Pruetz, doubtful that the mother is still alive. But knowing that wild chimps sometimes adopt orphans , Kante and pruetz decide they must try to return the baby chimp to its wild community. Kante pays another visit to the teenagers. After he explains how much trouble they are in, because chimps are an endangered species, he requests they should give him the frightened baby without payment. They agree. Kante takes the baby chimp to his home and feeds her milk from a bottle whenever she cries. The next morning, Pruetz and Kante leave the baby with another team member and begin their search for the wild chimps. Pruetz quickly finds the group in the woods. She recognizes the female that is without her child. Pruetz is so excited that she runs the entire mile back to bring the baby chimp to the tree where the chimps are hanging out. The researchers place the baby on the ground near the tree and back away. Almost immediately, a male chimp drops to the ground and stares at the baby curiously.

mmlu_stem | mmlu_stem_11662 | When Lady Gaga releases a new, pleasing and easily remembered single, it quickly goes around the world. Now scientists have discovered the same thing happens with the songs of another creature----the humpback whale. The mammals become absorbed by new tunes just like people do, and the most popular original whale songs spread globally like hit singles. Male humpback whales are famed for the loud, long and complicated songs they make during the mating season. Each song lasts for 10 to 20 minutes and the males can sing nonstop for 24 hours. At any one time, all the males in a population sing the same song. But a study shows that this song changes over time and spreads around the oceans. Dr. Ellen Garland of Queensland University, said: "Songs move like cultural communication from one population to another, causing all males to change their song to a new version." Researchers recorded songs from six neighboring populations of whales in the Pacific over a decade. They found that new versions of the songs appear over time and always spread from west to east. It takes two years for songs that appear in the waters off Australia to be heard in French Polynesia. Most of the new songs contain material from the previous year mixed with something new. " It would be like getting an old Beatles song together with U2," she said. " Occasionally they completely throw the current song out of the window and start singing a completely new song". Dr. Garland believes that a small number of whales may migrate to other populations carrying the new songs with them, or that they are heard by passing whales. The researchers suspect whales adopt new songs to make themselves distinct. Dr. Garland said: " we think this male search for new songs is in the hope of being that little bit different and perhaps more attractive to the opposite sex." According to the text, we can learn that _ | [

This price also includes an eightweek training course on an island. During their stay, guests would see the sunrise 15 times a day and travel around the world every 80 minutes. Galactic Suite Ltd's CEO Xavier Claramunt says the project will put his company in a leading position of a new industry with a huge future ahead of it, and forecasts space travel will become common in the future. "It's very normal to think that your children, possibly within 15 years, could spend a weekend in space" he told Reuters Television. A promising space tourism industry is beginning to take shape with construction in progress in New Mexico of Spaceport America, the world's first facility built specifically for passengers. British industrialist Richard Branson's space tours firm, Virgin Galactic, will use the facility to send tourists to space at a cost of $200,000 a ride. Galactic Suite Ltd, set up in 2007, hopes to start its project with a single pod in orbit 280 miles above the earth. "It will take a day and a half to reach the pod, and the passengers will join it for three days," Claramunt said. More than 200 people have expressed an interest in traveling to the space hotel and at least 43 people have already reserved it. The numbers are similar for Virgin Galactic with 300 people already paid or signed up for the trip, but unlike Branson, Galactic Suite says they will use Russian rockets to transport their guests into space from a spaceport to be built on an island in the Caribbean.

Edinburgh University already has the equipment to allow a small number of students to use computers during exams. Senior officials at Edinburgh University say that it is unfair to expect students to use pens and paper in exams when the majority of their coursework is done on computers. Undergraduates at the School of Divinity have the choice of using computers with their final answers being collected on a USB stick, but the take-up stands at less than 10 per cent. Dai Hounsell, professor of higher education at the university, said, "We've got to look at alternatives to the handwritten exam. Looking ahead ten years from now, I'm sure there will not be handwritten answers any longer in the exam of certain subjects, but how we get there from here isn't easy. The plan doesn't apply so much to science and engineering subjects where students have to use charts and mathematical formulae . There isn't technology at the moment to allow them to do that on a computer." He adds that the approval of students is the key before anything is carried out. He also said, "We don't want to put students' future at risk by experimenting as there are technical things which can go wrong. There could be a power failure." Nora Mogey, head of Media and Learning Technology Service at the university, said, "A lot of students are not _ enough to make that step in such an important situation.

mmlu_stem | mmlu_stem_4864 | You may have heard adults say they are uncomfortable in the morning without a cup of coffee. One reason they may feel that way is that coffee contains caffeine . Caffeine occurs naturally in coffee, tea, and cocoa beans, which are used to make chocolate. But now food makers are adding it to many products, from potato chips to water. The US government is especially worried about the problem. That's why the Food and Drug Administration (FDA) is studying the health effects of caffeine on young people. Studies show that too much caffeine can make people nervous and unable to sleep. What's more, caffeine is habit-forming. Those who consume it regularly and stop suddenly may experience headaches and feel tired. One of the biggest concerns is the large amount of caffeine added to so-called energy drinks, like Red Bull. A 12-ounce can of cola has about 35 milligrams of caffeine. A similar serving of Red Bull contains more than three times that amount. The Institute of Medicine is also working on caffeine-safety measures. "Teenagers should not drink beverages that contain caffeine. They should be aware of caffeine's effects on health and on how the brain works. Take, for example, teenagers who consume caffeine to stay awake and study for a test. They will remember less of what they just studied," said Stallings, a member of the institute. Companies that make products with added caffeine claim they do not advertise them to kids. However, there is no law to stop children from buying them. So the FDA needs to set limits on caffeine, especially in energy drinks. As for added caffeine in foods, the government should just say no. If not, the amount of caffeine should be printed on food labels to remind consumers. The government must do that. Doctors say kids should avoid caffeine. If you need extra energy, try these natural boosters: eat right, exercise, and get plenty of sleep. The author may agree that _ . | [

To answer those questions, we first have to understand what leaves are and what they do. Leaves are nature's food factories. Plants take water from the ground through their roots. They take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose, which is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis, which means " putting together with light. " A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is what gives plants their green color. As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange colors. Small a-mounts of these colors have been in the leaves all along. Covered up by the green chlorophyll, we just can't see them in summer. The bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color. The brown color of trees like oaks is made from wastes left in the leaves. It is the combination of all these things that make the beautiful colors we enjoy in the fall.
