mmlu_train_15763 | Many of today's parents fondly remember childhood days spent playing outdoors. When children make mud pies and observe ants, it may seem like just fun and games, but the truth is the outdoor play is an important part of growing up healthily. The National Association for the Education of Young Children reports that outdoor play reduces (make...less) stress and restlessness in children and improves their attention. Outdoor play is the perfect way to fight against the childhood's obesity(being fat).Research shows that children who play outdoors are more fit and thin, according to the National Center for Physical Development and Outdoor Play. Children who spend time outside on a regular basis also have healthier immune systems. And playing outdoors is a good way to get enough vitamin D. Playing outside enables children to relax , reduces tension and helps them solve problems. When children play outdoors, they learn to share and cooperate (work together) with one another. Kids who feel confident outdoors are likely to become able clever adults. The outdoors is a giant laboratory for learning that improves creative thinking and problem solving. Researchers have found that children learn best when their body, mind and spirit are involved , and this appears in outdoor play. Outside activities develop all five senses, which create a powerful learning environment. The outdoors also lets children have the chance to explore , experiment, form questions and create their own ideas about how the world works. Although there are the many advantages of outdoor play, time spent outside has been reduced for many of today's children. Kids today spend much more time in front of electronic media than children a generation ago. The lack of outdoor play is tied to the childhood widespread obesity. And experts predict that the situation is so serious that this generation will have much trouble when they grow up. To get kids involved with the outdoors, encourage them to collect rocks, fly kites, climb trees, garden, camp, swim, go fishing, watch birds and butterflies or play games with other children.

mmlu_train_52542 | "Any time! Any where! Decades ago there was no such thing" - "Communication". Then, September 7th 1987, the global system for mobile communication or GSM was born. And international agreements that laid out the standards, regulations and practices gave rise to a global mobile phone industry. To be honest, the world's first mobiles were not so attractive and the range of effectiveness wasn't very good. But they became a must-have among those wealthy people who could afford that. However, by advantage of GSM which has many different elements to it, we can all enjoy the ability to go around the world in 217 countries, land in that country and know that a phone would work. There are other cell phone systems using different technology in the world. The majority of the United States and parts of South America have been using something called CDMA which is very rare in Europe. In some Asian countries like China, GSM and CDMA both exist at the same time. But the GSM Association claims 85% of the global mobile phone market. They estimated there are now about 2.5 billion different users who make more than 7 trillion minutes of calls everyday, and that's not all. 20 years later, the mobile phone is so much more than just a phone. You can use it to send text messages, take pictures, show video, even surf the internet. "The phone itself is involved from just being a communication tool, to be a tool for round-the-clock connectivity, you can not live without it even in a minute." Mobile consultant Nick Lane also points out with so many customized styles and features, your mobile phone will become a symbol of you. Where will the global mobile phone industry be in another 20 years? Certainly, there will be more connections than better coverage. As for where else technology will take us, one can only imagine.

When 18th-century European museums were first sent specimens of a large furry animal with long curved white claws, they named it"bear-like sloth "because its claws resemble those of South American sloths. Later scientists realized that the species was a tropical bear unrelated to sloths, but its wrongheaded name remains the sloth bear. Rangingprefix = st1 /India,Nepal,Bhutan,Sri Lanka, and possiblyBangladesh, these 150 to 300-pound bears feed on fruits and insects. They sound like bellows when using their flexible noses and lips to blow away dirt and suck up ants.

Yognand often talks with villagers to help avoid conflicts."Attacks can be prevented if people avoid certain places."

mmlu_train_26286 | Entire populations of American toads breed within the same few days at the same time each year, usually late April or early May. The toads hop to their breeding ponds after the ground has warmed and the first hard spring rain falls. To get there, many of the toads will cross roads that cut through their habitat. It will be a grand view of hopping toads as well as a disastrous killing by cars! The toads are "slow in moving at that time of year--it's still cool, they've been inactive--and they get killed" by cars when crossing roads, said Serrao, a naturalist. An April night five years ago, when Serrao went out to a country road to watch the moving of the toads, he counted 100 toads; 95 were hit by cars. A similar story can be told for several other species of toads, frogs, crocodiles and turtles around the world. The world's amphibians are reducing, and road-killing is just one factor behind it. Other better-known causes of the decline include global warming, insecticides , and the loss of wetlands. Serrao says unless these animals get help crossing the road, their local populations will disappear. Jackson, a biologist, said one way to help amphibians survive road crossings is to construct "amphibian tunnels" beneath the road. Jackson says tunnels should be a 0.6-meter-by-0.6-meter box, open at the top, and fitted with an iron grate to allow enough air and light into the tunnel. In addition, fences or walls should extend out from either side of a tunnel for about 30 meters, which guide amphibians toward the tunnels. European countries have built amphibian tunnels for decades. Jackson led a team that installed the first such tunnel in prefix = st1 /Americain 1987, which helped over 3/4 of the local amphibian population safely cross the road. Jackson says that there are about a hundred amphibian tunnels in the UStoday, but many of them were not carefully designed and probably not working well because land developers wanted to save money.

mmlu_train_25430 | A US student has just spent 30 days on an "insect diet " - eating insects three times a day. Camren Brantley-Rios says traditional meats such as pork and beef are unable to continue and he wanted to try out what many consider the diet of the future. Many people would not like the idea of eating insects distasteful, even if it were not disgusting. Not so long ago Brantley-Rios was among them. But for the last month he has been eating insects for breakfast, lunch and dinner. "I'm mainly sticking to three kinds," he says. Occasionally he has included different insects. Preparing these he "actually cried", though he insists they were surprisingly good. Insects consume fewer resources than animals, like pigs and cows, to produce the same amount of protein , Brantley-Rios says - and more than two billion people worldwide include insects in their regular diet, according to the UN Food and Agriculture Organization. "There's not really a need to eat insects in America because we have it so nice," Brantley-Rios says. "We have finer meats and we're lucky to have that luxury , so there's not much of a pressure to eat insects right now. But what a lot of people are trying to do is make it a little bit more marketable." He has ordered insects from farms that usually supply zoos, which need them "to feed certain animals". He has always made sure the insects have been fed on an organic diet, he says, and only bought species he knows are safe to eat. He knows that one person eating insects won't make much difference. To have a real environmental effect, millions would have to follow his example. Why has the US student tried out an "insect diet"? | [

mmlu_train_55173 | It's time you started eating sensibly. Experts at the first Chinese Students Nutrition and Health Festival in Kunming last week listed eight bad eating habits. *Watching television while having meals or snacks. Doing this means you don't pay attention to your food, forget how full you are, and so overeat. It can also cause digestion diseases. One way to avoid this is only to eat in certain areas of your home. * Replacing meals with snacks. Many students think that eating small snacks can help them diet. But it often results in overeating and health problems related to a lack of vegetables, carbohydrates ,proteins and vitamins. Snacking only works if it is well planned and includes healthy foods such as nuts, vegetables, fruit and yogurt. *Having drinks rather than water. Fizzy drinks and fruit juice are usually high in calories and sugar, which can cause weight problems. Water is important in making your brain cells and every organ in your body work properly. For your body to burn fat, it needs at least eight glasses of pure water a day. Liquids like soda and coffee actually take water away from your body. *Refusing to drink milk. Milk is the best natural food--it provides you with protein, which makes your bones strong and teeth healthy. * Choosing meat and certain vegetables over others. Different foods provide different kinds of nutrition. If you don't have a balanced diet, this can result in malnutrition and a weaker body. *Eating in front of the computer and staying there after meals. Take a walk after eating and it helps your stomach digest the meal. *Buying from roadside snack bars. If you shop at these places, be careful--many are not clean enough. * Eating throat tablets as if they were sweets. If you eat throat tablets when you have no throat disease, they may affect the bacteria in your mouth and cause real throat problems.

mmlu_train_9788 | In the United States, 30 percent of the adult population has a "weight problem.". To many people, the cause is clear: We eat too much. But scientific evidence does little to support this idea. Going back to the America of 1910, we find that people were slimmer than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn't watch television. Several modern studies, moreover, have shown that fatter people don't eat more on average than thinner people. In fact, some investigations (researches), such as a 1970 study of 3,545 London office workers, report that, on balance, fat people eat less than slimmer people. Studies show that slim people are more active than fat people. A study by a research group at Stanford University School of Medicine found the following interesting facts. The more the men ran, the greater loss of body fat. The more they ran, the greater their increase in food intake . Thus those who ran the most ate the most, yet lost greatest amount of body fat.

mmlu_train_5825 | American black bears appear in a variety of colors despite their name. In the eastern part of their range , most of these bears have shiny black fur, but in the west they grow brown, red or even yellow coats. To the north, the black bear is actually gray or white. Even in the same litter , both brown and black furred bears may be born. Black bears are the smallest of all American bears, ranging in length from 5 to 6 feet, weighing from 300 to 500 pounds. Their eyes and ears are small and their eyesight and hearing are not as good as their sense of smell. Like all bears, the black bear is shy, clumsy and rarely dangerous. However, if cornered, the black bear can become a fearful enemy. Black bears feed on leaves, roots, fruit, insects, fish and even larger animals. One of the most interesting characteristics of bears, including the black bear, is their winter sleep. Unlike many other animals, bears do not actually hibernate . Although the bear does not eat during the winter months, its temperature remains almost normal, and it breathes regularly four or five times per minute. Most black bears live alone, except during the mating season . A litter of one to four cubs is born in January or February and they remain with their mother until they are fully grown or about one and a half years old.

It is very easy to cook it instantly by putting the noodles into the boiling water and add in those MSG packets, together with your other ingredients like eggs or vegetables. However, have you ever wondered whether this is the correct way of cooking it? When you first took out the noodles from the packaging, you will notice that the noodles are joined together nicely as a piece. In order to make the noodles joined together nicely side by side, it needs some form of wax coating to achieve an attractive instant noodles in front of us. Many people who enjoy eating instant noodles frequently do not really bother too much of it, as it seems very normal to everyone to have it nicely displayed in front of us. However, researches have shown that the layer of wax coating on the noodles is quite harmful to our body and we should not eat it too frequently. It is advisable to have a break of 2-3 days before we start to eat another packet of instant noodles as our body need about 3 days to clear that layer of wax coating away from our body system. Do you know the danger of having too much wax coating stored in our stomach? It will lead to CANCER if it is stored in our body system for a long period of time. There are 2 keys points to take note while preparing instant noodles: 1) Wash the instant noodles with warm water first, stir it and pour away the water containing the wax coating. 2) Repeat Step 1 and try to stir the noodles again to wash away the wax coating on the noodles before cooking it in a new pot of water.

It may even help improve your test scores. This exciting research is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath. Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That's because the lining of our cheeks can absorb certain substances more quickly than our stomachs and intestines can. That discovery could help other researchers develop medicine-containing gums that fight colds, ease headaches, battle nervousness, and more. Scientists might even create antimicrobial gums that cure bad breath. Those projects may take years, but gum scientists have already had at least one recent success: They've created a gum that could help us stay awake. Researchers have produced a gum called Stay Alert. Each stick has as much caffeine as a cup of coffee. It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert _ in just a few minutes. The gum is easy to transport and it's stable in cold and hot climates. Unlike a pill, it doesn't require water to swallow. Those qualities make it easy for soldiers to use.

" There is a great push so that people can live from 120 to 180 years," he said. " Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years." However, many scientists who research into aging are doubtful about _ and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death. Scientists also disagree on what kind of life the super aged might live. "It remains to be seen whether you could be healthy enough to have good quality of life when you pass 120." said Leonard Poon, director of the University of Georgia Gerontology Center. " At present people who could get to that point are not in good health at all." By saying " we are knocking at the door immortality", Michael Zey means _ . | [

mmlu_train_16391 | Centuries ago, man discovered that removing moisture from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind. In this way the North American Indians produce pemmican(dried meat ground into powder and made into cakes), the Scandinavians make stockfish and the Arabs dried dates. All foods include water--cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish, anything from 80% to 60%, depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is checked. Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. Various methods are used, but in general, the fruit is spread out on trays in drying yards in the hot sun. Nowadays most foods are dried mechanically. The method of such dehydration is to put food in chambers through which hot air is blown at temperatures of about 110degC at entry to about 43degC at exit. This is the usual method for drying such things as vegetables, minced meat, and fish. Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to the climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them. Usually it is just a case of replacing the dried-out moisture with boiling water.

The findings agree with the research suggesting all that inactive sitting and always watching advertisements may lead to poor eating habits. Researchers used results from a long-term study of children who took part in the surveys every two years. Children were between ages 9 and 16 when the study started. Out of 4,300 girls in the study, 17 percent were overweight or obese . Twenty-four percent of the 3,500 boys were also above a healthy weight. The surveys included questions about their height and weight as well as how much time they spent watching TV and DVDs and playing computer and video games. From one survey to the next, each one-hour increase in children's daily TV watching was in connection with an increase of about 0.1 points on a body mass index (BMI) , which measures weight in connection with height. There's an increase of about half a pound in weight per extra hour of TV. "The weight of the evidence is so strong that television watching is connected with unhealthy changes in weight among youth," says Jennifer Falbe, who led the study while at the Harvard School of Public Health in Boston. "It's important for parents to know that all the obesity-causing screens really should be limited in their children's lives." Falbe says. "When children watch TV, there are many food advertisements on TV that might lead them to eat a cookie or drink a soft drink." What's more, she says, "they can get into a hibernating state on the sofa, even if children are sitting down while playing a computer game."

What a great snack choice! Not only is an apple low in calories, they contain absolutely no fat. Thus, eating apples as snacks, as opposed to chips or cakes, will help reduce the risk of cancer. On top of reducing the risk of cancer, the low sodium amounts in apples also help reduce high blood pressure and heart disease. They are cholesterol free. They are also rich in vitamin A, which helps strengthen vision along with bone and tooth development. Now that we know the nutritional facts, let's take a look at some of the fun facts--That's right! Apples can be fun, as well as healthy! If an apple is fresh, it will float on water. Twenty-five percent of an apple is air, thus allowing it to float. Can you imagine bobbing for apples that sink?

At 17, his father tired to persuade him not to become a mathematician because he may lead a poor life being a mathematician, and so von Neumann agreed to study chemistry as well. In 1926, at 23, he received a degree in chemical engineering and a Ph.D. in mathematics. From then on, mathematics provided well enough for him, and he never had to turn to chemistry. In 1930, von Neumann visited Princeton University for a year and then became a professor there. His first book was published in 1932. In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics(Einstein was one of the others) World War II hugely changed von Neumann's areas of interest. Until 1940 he had been a great pure mathematician. During and after the war, he became one of the best mathematicians who put mathematics theories into practice. During the last part of the war he became interested in computing machines and made several fundamental contributions After the war, von Neumann continued his work with computers, and was generally very active in government service. He received many awards, was president of the American Mathematical Society and was a member of the Atomic Energy Commission. He died in 1957 of cancer. Von Neumann made several great contributions and any one of them would have been enough to earn him a firm place in history. He will be remembered as one of the greatest minds of the 20th century.

mmlu_train_48871 | A house of cards? Sounds unbelievable, doesn't it? Not if the architect is 31-year-old Bryan Berg. He's made a career out of building fantastic card houses, stadiums, capitols, castles -- and the world's tallest card tower. How does he do it? Bryan's structures are amazing because they are made entirely of perfectly balanced, freestanding playing cards. He never uses glue, tape, or anything else to hold the cards together. Nor does he fold the cards. He's discovered another way to make a strong house of cards, using a trick from nature. To make plants strong, nature builds them with cells that have tough walls. Rows and rows of these cells form a grid that helps leaves and stems keep their shape. Bees use the same kind of repeating pattern to create strong honeycombs, where they live and store honey. Bryan designs similar grids, using cards to create a repeating pattern of cells. He begins with a single cell made by balancing four cards against one another to form a box. Then he repeats the cell over and over, expanding outward to form the grid, which makes a good foundation for a strong card structure. The larger the grid, the more weight it can carry. Sometimes Bryan uses several cards, instead of just one, to construct the cell walls, making the grid even stronger. The trick, he tells kids when he speaks in classrooms, is to place your cards as tightly together as possible when laying out your grid, making sure the cards are not leaning at all. After building this solid base, Bryan lays cards across the top to make the floor for the next "story" of the building. He may add towers, columns, steeples, or domes. Using the principle of repeating cells, Bryan builds structures of amazing strength. In the Cards Not surprisingly, Bryan has always been interested in building things. Growing up on a "big, old farm" in rural Iowa, he had plenty of room to play. "We were in the middle of nowhere," Bryan remembers, "with lots of space to do whatever we wanted. I was always making something, using things like sticks or bales of hay." Bryan's grandfather taught him how to stack cards. Bryan's two interests -- building and card stacking -- soon combined. But stacking in his family's farmhouse was challenging. "Our old house had wood floors that weren't all level," he reports. "And they weren't very firm. When people walked around, it was like 'earthquake action.' It was a challenge to build something that wouldn't fall down immediately." Bryan constructed tower after tower; he went through a lot of trial and error before he built anything taller than himself. When he placed a few decks of cards on top of his grid, he discovered how strong it was. Bryan's towers began to grow taller. How Tall Is Too Tall? Bryan's first Guinness World Record for the world's tallest card tower came in the spring of 1992, when he was in high school. Learning that the world record was 12 feet 10 inches, Bryan built a slim tower that topped out at 14 feet 6 inches. Done as a project for his geometry class, it took him 40 hours and 208 decks of cards. Since then he's gone on to win world records for even taller buildings. His latest winner measured 25 feet 3.5 inches and used about 2,400 decks of cards. _ Why don't these towers fall down? The key is in a good solid base, a repeating pattern of stories, and a tapering top. Bryan likes to point out how card buildings resemble real ones. They are built cell by cell, story by story. The separate parts make one strong whole. The heavier the building, the stronger and more stable it is. But the weight can't all be at the top. After spending so much time building something so cool, Bryan admits it's sometimes painful to see his structures destroyed. But he compares his work to the building of a sandcastle or an ice sculpture. "They wouldn't be as special if they were permanent," he points out. "My buildings are like snowdrifts, or clouds in the sky. They can't last forever. According to the article, which natural structure is a model for Bryan's card structures? | [

mmlu_train_63965 | 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 _ | [

mmlu_train_4959 | Scientists from England's Newcastle University have discovered that bacteria have the ability to detect smells, according to a study by the university on Sunday. The team of scientists, led by Dr. Reindert Nijland, discovered that bacteria can detect certain types of smell- producing chemicals, including ammonia that is produced by other bacteria. Once they sense the smells from other kinds of bacteria, the bacteria will gather together to form a colony and form a layer of slime in order to force the competitors out of their area. The response decreases as the distance between the two bacterial colonies increases. That slime, also known as biofilm, is one of the primary causes of infection on many medical implants . Biofilms also slow down ships and are believed to cost the marine industry millions of dollars annually. However, they can also be used to clean up spilled oil floating on the sea, as they grow strong on it. "This is the first evidence of a bacterial 'nose'able to detect potential competitors," Dr. Nijland said in the August 15 statement, which confirms that bacteria possess qualities similar to four of the five senses that humans enjoy (sight, hearing, touch, taste, and smell), the others being touch, taste, and sight. "The fact that bacteria formed slime when exposed to ammonia has important significance for understanding how biofilms are formed and how we might be able to use them to our advantage," he added. Their findings were published in Sunday's edition of biotechnology journal, and could change the way scientists look at how each of the senses developed over time. "It was thought for a long time that smell existed only in complex living creatures," Dr. Nijland said. "Now we see that bacteria are able to do the same, so the indication is that the ability may have developed even earlier." Which of the following describes bacteria correctly? | [

mmlu_train_36886 | People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking. They try to find a solution by trial and error. However, when all these methods fail, the person with a problem has to start analyzing. There are six stages in analyzing a problem. First the person must recognize that there is a problem. For example, Sam's bicycle is broken, and he cannot read it to class as he usually does. Sam must see that there is a problem with his bicycle. Next the thinker must define the problem. Before Sam can repair his bicycle, he must find out the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific. Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully. After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels. Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels. Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. he has solved the problem.

mmlu_train_52858 | In 1975, George Carlin appeared on a popular TV show, Saturday Night Live, with his famous words about blue food. "Why is there no blue food? I can't find blue food--I can't find the flavor of blue! I mean yellow is lemon; orange is orange and red is cherry. Where is the blue food? " Well, Carlin pretty much has it right--there's not no blue food, but there's certainly not a lot of it. Fresh-picked blueberries are blue, though they become purple when they are turned into jam. The blue in blueberries--like the purple in grapes and the red in tomatoes--is found in nature. But it isn't a hot color for food. People don't seem to prefer blue food. Some diet programs even suggest that those determined to lose weight should make their food blue. Eating, in part, begins with our eyes. Charles Spence--an experimental psychologist from Oxford University--points out that color can change our taste experience. Commonly, we consider red-colored foods up to 20% sweeter than they actually are; and green foods as being more sour. Spence suggests: human expectations may be influenced by our long history of watching - green fruits can become sweet as they grow up and turn red. But what about blue? Except blueberries, much of the blue food we see these days _ blue artificially. Food producers argue that artificial color doesn't do much harm to health. A lot of research shows that some physical problems of kids are related to food dyes--while other studies show no effects at all. Blue birthday cake or even blue-dyed chicken can be served on the dinner table. So what? . Which of the following statements of blue is true? | [

mmlu_train_10646 | A new report said scientists may not be far from giving apes the ability to think and talk like humans. The report is about experiments which transplant human cells into animals for medical purposes. It claimed that concerns about the creation of talking apes should be taken seriously. It should also draw people's attention to the possibility that the medical research about creating "humanised" animals is going to generate monsters. A regulatory body is needed to closely monitor any experiments that many risk creating animals with human-like consciousness or giving them any appearance or behavioural traits that too closely resemble humans, the report said. Scientists would, for example, be prevented from replacing a large number of an ape's brain cells with human brain cells until more is known about the potential risks. This has already been done in simpler animals like mice, which is judged to be less risky. Under the new UK guidelines, the power to regulate tests on animals containing human material would be transferred to a body with wider responsibility for animal testing in the Home Office. While there is no risk from experiments currently being carried out in Britain, it is possible that ethical boundaries could be crossed within the next few years if scientists are not careful, the experts said. Professor Thomas Baldwin, a member of the Academy of Medical Sciences working group that produced the report, said the possibility of humanised apes should be taken seriously. He said, "The fear is that if you start putting very large numbers of human brain cells into the brains of primates you might transform the primates into something that has some of the abilities that we regard as distinctly human, such as speech, or other ways of being able to _ or relate to us." Professor Martin Bobrow, chair of the academy working group that produced the report, said, "The very great majority of experiments present no issues beyond the general use of animals in research and these should continue to proceed under the current regulations." Lord Willis, chair of the Association of Medical Research Charities, said, "AMRC only supports research that is absolutely necessary and where no suitable alternative methods are available."

There is an amazing new product on sale in prefix = st1 /Japanwhich does exactly this. It is an LP (a long-playing record) of sounds from inside a mother's body, which a hospital doctor recorded. In tests with the record she played the LP to 403 crying babies. After 41 seconds not one baby was crying and 161 of them were sleeping. The record began as an experiment by Professor Hajime Minooka of the Nippon Medical University near Tokyo. He was looking for something natural that helped new-born babies go to sleep. The sound of the mothers' heart-beat and other body sounds are the things the babies heard inside their mothers. They feel safe and happy when they hear these sounds again. And they go to sleep. Hospitals in Osaka and Tokyoare using the LP. 10, 000 young couples are using it too. Toshiba Music Company who makes and sells the records is very happy.

mmlu_train_27791 | We live in a sweet world. The average American kid consumes more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn't good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to conduct a study on the negative effects of sugar. They found it could have serious effects on people's health. Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers. During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice were 26% less territorial and produced 25% fewer offspring than the other mice. Scientists often use mice for research because they have a similar genetic structure to humans. "Since most substances that are dangerous in mice are also dangerous in people, it's likely that those physical problems that cause those mice to have increased deaths also work in people," says study author James Ruff of the University of Utah. Findings from this study reveal negative effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives. Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation's sugar desire will provide for a truly sweeter future. The study conducted by researchers aimed at learning about _ | [

When an automatic washing machine is switched on, water pours in. The machine waits until the water is hot before washing the clothes. It does this by "feedback". Information about what is happening is "feedback"into the robot to tell it what to do next. Our eyes,ears and other senses are our feedback. They tell us what is going on around us. So robots are like people in two ways:They work and they have feedback. There are robots all around, making our lives easier. Some of them, like the pocket calculator, can work much more quickly than human beings can. And they rarely make mistakes. In some ways robots are better than people. They work quickly, but do not make mistakes. They do not get bored doing the same job over andover again. And they never get tired. Robots are very useful in factories. They can be taught to do many different jobs. First their electronic brains must be shown how the job is done. A person moves the robot's"arm"and"hand"through each part of the job. The robot's brain remembers each move. When the robot is put to work on its own, its brain controls the rods, wheels and motors which move its arm. When the robot is needed for a new job, its electronic memory is"wiped clean."Then it is taught how to do its new task. If the robot's hand stops working, or if something gets in the way, it cannot do the next part of the job. So it stops and signals for help, then a human engineer repairs it. The most"intelligent"robots can move and see. Their eyes are cameras. Their metal fingers can feel shapes and even find out how hot and cold objects are. These robots have computer brains, linked to their eyes and fingers, which control their actions. What does the author of this story want you to feel about robots? | [

mmlu_train_49881 | Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful animals feeding on meat. They feast on marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches (ten centimeters) long. They are known to grab seals right off the ice. They also eat fish, squid , and seabirds. Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator . Killer whales hunt in deadly groups, family groups of up to 40 individuals. There appear to be both permanent and temporary group populations of killer whales. These different groups may hunt different animals and use different techniques to catch them. Permanent groups tend to prefer fish, while temporary groups target marine mammals. All groups use effective, cooperative hunting techniques that some are similar to the behavior of wolf packs. Whales make a wide variety of communicative sounds, and each group has various noises that its members will recognize even at a distance. They use echolocation to communicate and hunt, making sounds that travel underwater until they meet objects, then reflect back, showing their location, size, and shape. Killer whales are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a 17-month pregnancy. Killer whales are immediately recognizable by their special black-and-white coloring and are the intelligent, trainable stars of many aquarium shows.

And are there any ways parents can help kids stay away from bad games? US researches are trying to find answers to these questions.

mmlu_train_48528 | The koala is possibly one of the best known Australian animals, and is found in four states: Queensland, New South Wales, Victoria and South Australia. The word "koala" comes from an Australian aboriginal word meaning "no drink". Sometimes people call them "koala bears" but koala is not a bear. It belongs to a special group of Australian mammals, called marsupial . Female marsupials have a _ where the baby animals live after they are born. Koalas have soft, thick, grey or brown fur on their backs. The fur on the stomach is white. Koala that live in the south have thicker fur than those in the north because of the cold winters, whereas the koalas in the northern part of the country live in warm to hot weather most of the year so have thinner fur. A koala has a large hairless nose and round ears. Koalas don't have tails. Adult koalas measure between 7 and 14 kilograms. Koalas spend nearly all their time in the trees using their sharp, curved claws and long toes to climb about and to hold on to the tree branches. They sleep most of the day, and feed and move from tree to tree mainly at night. The reason koala sleep for much of the day is because their food eucalyptus leaves are very tough so they use a lot of energy to digest. Sleeping saves energy. Eucalyptus leaves are poisonous to almost every other animal. Koalas rarely drink water; they get water from the leaves they eat. Each koala has a home range made up of several trees that they visit regularly. They normally do not visit another koala's home trees except that a male is looking for a female to mate with. Why do koalas sleep much in the day? | [
