mmlu_train_10203 | It seems that many parents have a lot to learn about what their children are doing online. According to a recent survey by the Symantec Corporation, which makes many kinds of security software for home and business computers, there's a "significant digital divide between parents and their kids." Parents of children under the age of 18 were asked to estimate how much time their kids spent online each week. The parents said about three hours a week on average. The kids - ages 8 to 17 - who took the survey said they're spending an average of seven hours online each week. "I really think that's due to the time they spend on their mobile phones and computers, when their parents don't even know they're online," says Symantec's Bill Rosenkrantz. "Remember, cell phones, PDAs and video game machines all make it possible to access the Internet. You don't have to sit in front of a computer screen." And what are the kids doing on the Web? "They're doing things like downloading music, they're going to social networking sites, they're actually shopping online when parents don't think they're doing those kinds of activities," says Rosenkrantz. "They're also, we think, doing some things with research papers and other kinds of activities with homework maybe where they're getting content online and they really shouldn't be." Nearly a quarter of the kids (23 percent) admit to doing things their parents would not approve. So how does a modern parent deal with this type of situation? "The first thing we strongly recommend is that parents spend time with their children online," Rosenkrantz says. "Sit down with them and understand what they're doing. Secondly, have a dialog about it. Have a dialog about what's an acceptable activity, what's an unacceptable activity, and set some ground rules -- time online, things you can and can't do. Really have those conversations. That's the most important." There are a lot of bad people on the Internet. That's why it's so important for parents to know what their kids are doing online.

mmlu_train_10477 | The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms. After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London. Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London. "The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire. At the peak of the cycle, violent outbursts called coronalmass ejections occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots. Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available. The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares and explosions as they occur. Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advance warning, we'll be able to reduce the damage. _ According to the passage, NASA will launch a satellite to _ | [

Try think about sheep jumping over a fence. If you are still awake, take a sleeping pill. People who take pills often become dependent on the drugs. So you lie awake knowing that the new workday will soon arrive. If you have been in such condition for at least one month, you may have primary insomnia . A new study has found that you might fall asleep more quickly and stay asleep longer if you try "cerebral hypothermia." It is not a complex medical process. It just means cooling down your brain. Eric Nofzinger and Naniel Buysse from the University of Pittsburgh Medical School led the study. They examined twelve people who had sleeping problems. Twelve others had no sleeping problems. Each of them wore a soft plastic cap on their head at bedtime. The caps had tubes inside filled with water. The researchers moved the water through the tubes and then changed the temperature of the water. Other studies showed that people who had sleeping problems often had more chemical reactions in the front of their brain. The researchers thought cooling down the brain might help. On the first two nights of testing, the patients wore caps with no water. On the next two nights, the caps were worn, but the water was not cooled. Then the researchers cooled the water a little for another two nights. On the final two nights of the study, the temperature of the water was made much cooler. The researchers found that the water caps didn' t help the patients until the temperature was about 14degC. Most of the patients fell asleep faster and slept better when the coolest water was moving around their head. Dr Nfzinger and Dr. Buysse noted that this was only the beginning of the brain temperature study. But they believed they had discovered something important that needed more research.

mmlu_train_62717 | All people need to sleep. Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep. Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the likelihood of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for mainly sleep. TVs, computers and other things should not be in your bedroom if at all possible. Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time. Develop a regular exercise program. Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate your body and make sleeping more difficult. Establish a pre-bedtime rule that will help focus you on sleep. You can try meditation ,reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is the best for you. Things such as room temperature, noise and light levels and even your bed mattress can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights.

mmlu_train_16307 | Recently a study, led by Pedro Hallal of the Federal University, suggests that nearly a third of adults, 31%, are not getting enough exercise. That rates of exercise have declined is hardly a new discovery. Since the beginning of the industrial revolution, technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently have enough good data been collected from enough places to carry out the sort of analysis Dr Hallal and his colleagues have engaged in. There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men--34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, move more than their male countrymen. Malta wins the race for most _ country, with 72% of adults getting too little exercise, and Swaziland and Saudi Arabia are in close behind, with 69%. In Bangladesh, just 5% of adults fail to exercise enough. Surprisingly, six Americans in ten are active enough according to Dr Hallal's study, compared with fewer than four in ten British. These high rates of inactivity are worrying. Human beings seem to have evolved to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span as smoking. According to the study, women of Luxembourg _ . | [

mmlu_train_31172 | More and more people are coming under the umbrella of fatness in modern times. Not just adults,but even children are getting overweight. Today some of the newborn babies are also born fat. It has been proved that the people living in the developed Western countries are more likely to become overweight. There are a number of causes behind this. The people in the developed countries including the United States almost enjoy all the comforts of life. Almost all the things in the lives of the people living in these countries are at their fingertips. A very limited amount of movement and physical effort is required to do any kind of job. Because of the fact that these countries are quite developed,most of the jobs that the people take up are desk jobs. So the lifestyle of them is just around the office desk. Most of the developed Western countries are cold ones. Nature demands that people eat the food that can somehow make them stand the coldness. Therefore,wine,fatty dairy products,bread,junk food and red meat become an important diet in these countries. However,the blame cannot be entirely put on the unhealthy eating habits of the people. Technology allows them to import almost all the food products that they do not grow. Although some healthy food are grown in the countries nowadays,the quantity is very limited. It is not enough to meet the demand. So when they are not available and fatty foods are cheaper,then people prefer to go for the eating habit that they have always been following.

mmlu_train_11860 | That day It's 4 am,and Danilo C.Dequina is already awake. Holding a flashlight and a bucket, he is walking in the pre-dawn darkness along the shore of Old Poblacion Beach in the town of Maitum,Sarangani,in the far south of the Philippines. A few minutes later,he spots a patch of sand that appears to have been disturbed by a turtle. Dequina studies the area carefully,figuring out where the eggs have been buried, and then starts digging slowly. After clearing away several centimeters of sand, he uncovers a large group of eggs,roughly the size of ping-pong balls. He picks them up and puts them in the bucket. Dequina carries the eggs to his hatchery , some 50 meters away from the seashore. The hatchery is really just a sandy patch of land under the coconut trees enclosed by a black fine-mesh fence. It is here that he buries the turtle eggs he has collected. Today,Dequina scoops out a hole,puts the eggs in it,and covers them with sand. After 45 to 70 days, the eggs will hatch. Dequina will then carty the hatchlings to the shore,and release them into the sea. He admits to feeling sorrow as he sets the hatchlings free most are hunted down by natural predators,and just one percent survive to adulthood. According to the Philippine Department of Environment and Natural Resources (DENR), eight species of sea turtles face extinction,including four that come to the shores of Sarangani to lay their eggs --the Hawksbill,Olive Ridley,Loggerhead and Green Turtles. After learning about their _ , Dequina attended a DENR training session on turtle conservation and decided to take action. He helped the local government to set up the Pawikan Nesting Sanctuary next to his house in 2003. The hatchery drew the attention of the locals. "They started to change their attitudes towards sea turtles,"52-year-old Dequina says. "If they see turtle eggs,they will either bring them to me or inform me of the nesting places."

mmlu_train_51363 | In the 1950s, a family that owned a farm near Beulah, Michigan kept a bull chained to an elm . The bull paced around the tree, dragging the heavy iron chain, which led to a groove in the bark . The groove deepened over the years. Though for whatever reason, it did not kill the tree. After some years, the family took their bull away. They cut the chain, leaving the loop around the tree and one link hanging down. Then one year, agricultural disaster struck Michigan in the form of Dutch Elm Disease. All of the elms lining the road leading to the farm became infected and died. Everyone thought that the old elm would be the next. The farm owners considered doing the safe thing: pulling it out and cutting it up into firewood before it died. But they simply could not bring themselves to do it. It was as if the old tree had become a family friend. So they decided to let nature take its course. Amazingly, the tree did not die. Nobody could understand why it was the only elm still standing in the county! Plant experts from Michigan State University came out to observe the tree. They observed the scar left by the iron chain, now almost completely covered by bark. The experts decided that it was the chain that saved the elm's life. They reasoned that the tree must have absorbed so much iron from the chain that it became immune to the virus. It's said that what doesn't kill you will make you stronger. Or, as Earnest Hemingway put it, "Life breaks us all, but afterwards, many of us are strongest at the broken places." Which of the following statements is TRUE? | [

mmlu_train_24594 | Sharing not only exists between humanbeings.As is often seen that some plants and anima1s live close together, and they depend on each other. They are usually very different from their partner, and yet all live easier lives because of each other. It is nature's idea of sharing. An example of a partnership is the shark and pilot fish. The pilot fish is a little fish only about nine inches long. He would be. helpless if he hung around by himself in the mighty ocean. He makes up for his size with his smartness. He cleverly swims along beside the shark. When the shark eats, the pilot fish gets the leftovers. And the pilot fish needn't worry about his safety. The shark also gets benefits from this relationship. The pilot fish cleans food scraps and insects from the shark's hide. Another example of depending on each other is the sea anemone and striped clown fish. The sea anemone looks like a flower and has petals that contain poisonous stinging cells. When small fish swim into the petals, the anemone traps and paralyzes them. However,the striped clown fish is able to swim into the poisonous petals without being harmed. When he is in danger, he quickly swims into the sea anemone and is unable to be seen by his enemies. To pay for his safety,the clown fish brings food to the anemone. He also guides other fish into the anemone's deadly trap. Large mammals such as the ox, antelope, rhinoceroses and African buffalo form such a relationship with the red-billed ox-peeker. They provide daily meals for the bird. In fact the bird eats insects. The various large mammals act as a restaurant with a varied menu for the ox-peeker. What do they get in return from the bird? Free beauty treatments! Some plants live together in a beneficial relationship of symbiosis. The fungus does not have chlorophyll that plants need to make food. However, green algae does contain chlorophyll. It is, therefore, able to feed the fungus along with itself. But nothing is free! The fungus repays it by protecting the algae.

This funny-looking animal has feet and is a kind of warm-blooded mammal. While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus'mouth is not really like ducks'at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater. Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles , with legs on the sides of their bodies rather than under them. Though pretty, in a special way, the platypus is actually one of the few mammals that are poisonous. A male platypus has knife-like bones on its back legs which have enough poison to kill a dog.

mmlu_train_40598 | Lucy, whose skeleton was discovered in Ethiopia in 1974, died shortly after she fell out of a tree, according to a new study published Monday in the British journalNature. For their research, Kappelman and Dr. Richard Ketcham used a CT scanner to create more than 35,000 "slices" of Lucy's skeleton. Scientists named her Lucy from the Beatles song "Lucy in the Sky with Diamonds", which was played at the camp the night of her discovery. The following analysis of the slices showed sharp, clean breaks seen at the end of Lucy's right humerus are similar to bone breaks seen in victims of falls. The researchers concluded that these and other breaks in her skeleton show that Lucy, who is believed to have stood about 3 feet 6 inches and weighed about 60 pounds, fell feet first and used her arms to support herself -- but that the injury was too severe to have been survivable. The researchers estimate that Lucy was going about 35 miles an hour when she hit the ground after falling from a height of roughly 40 feet, according to the statement. That sounds _ . But other scientists are doubtful. "There are countless explanations for bone breaks," Dr, Donald C, Johanson, director of the Institute of Human Origins and one of the scientists who discovered Lucy, said, "The suggestion that she fell out of a tree is largely a just-so story and therefore unprovable." Johanson said it was more likely that Lucy's breaks occurred long after she died, saying that "elephant bones appear to have the same kind of breaks, It's unlikely they fell out of a tree. " But the new research focused on "a small number of breaks" that are consistent with "high-energy bone-to-bone influences" and which differ from the sorts of breaks commonly seen in other collected bones. Kappelman responded in an email, "These appear to have occurred at or near the time of death." Which of the following would Johanson probably agree? | [

It's a way of saying the person has a large frame, or skeleton . Big bones usually weigh more than small bones. That's why it's possible for two kids with the same height, but different weight, to both the right weight. Being overweight can run in someone's family, but it may not be because of their genes. Poor eating and exercise habits also run in families and these may be the reasons the members of a family are overweight. And even though some kids gain weight more easily than others, when they eat right and exercise, most kids can have a healthy weight that's right for them. It's true- the way you live can change the way you look. How much your weight is a balance between the calories you eat and the calories you use. If you eat more calories than your body needs to use, you will gain too much weight. If you spend you free time watching TV, your body won't use as many calories as it would if you played basketball, skated, or went for a walk. But if you eat more and exercise less, you may become overweight. On the other hand, if you eat less and exercise more, you may lose weight. If two kids are of the same height _ . | [

mmlu_train_23312 | Remembering your dreams will require some efforts on your part. But what your dreams can offer and tell you about yourself will be well worth _ Here are some tips to help recall your dreams: 1. Before going to bed, keep a clear mind. Tell yourself that "I will remember my dreams when I wake up". This is actually a proven and effective way to recall your dreams. 2. Have a regular bedtime and wake-up time. Make this your routine. Going to bed and waking up at a regular time every day could aid in dream recollection. 3. Avoid alcohol consumption and taking medicine before going to bed. These things may prevent you from remembering your dreams. 4. Keep a pencil and a notebook next to your bed so that they will be within reach as soon as you wake up. Having a small lamp by your bedside is also a good idea, so you wake up in the middle of the night and can record your dreams immediately. 5. Do not get out of bed immediately. Upon waking from a dream, lie still in your bed, keeping your eyes closed and moving as little as possible. Let your mind wander among the images of what you have just dreamed. 6. Write down as many details in your dreams as you can, no matter how seemingly unimportant they may be. Do not judge the content or worry if they make sense. 7. Sometimes it may help to draw pictures. A picture is worth a thousand words, as the saying goes. Even if you are not an artist, a simple drawing can help to recall details of your dreams.

mmlu_train_30175 | Northern Europeans spend a lot of time in their cold and cloudy winters planning their summer holidays. They are proud of their healthy color when they return home after the holiday. But they also know that a certain amount of sunshine is good for their bodies and general health. In ancient Greece people knew about the healing powers of the sun, but this knowledge was lost. At the end of the nineteenth century a Danish doctor, Niels Finsen, began to study the effect of sunlight on certain diseases, especially diseases of the skin. He was interested not only in natural sunlight but also in artificially produced rays. Sunlight began to play a more important part in curing sick people. A Swiss doctor, Auguste Rollier, made full use of the sun in his hospital at Lysine. Lysine is a small village high up in the Alps. The position is important: the rays of the sun with the greatest healing power are the infra-red and ultra-violet rays; but ultra-violet rays are too easily lost in fog and the polluted air near industrial towns. Dr. Roller found that sunlight, fresh air and good food cure a great many diseases. He was particularly successful in curing certain forms of tuberculosis with his "sun-cure". There were a large number of children in Dr. Roller's hospital. He decided to start a school where sick children could be cured and at the same time continue to learn. It was not long before his school was full. In winter, wearing only shorts, socks and boots, the children put on their skis after breakfast and left the hospital. They carried small desks and chairs as well as their school books. Their teacher led them over the snow until they reached a slope which faced the sun and was free from cold winds. There they set out their desks and chairs, and school began. Although they wore hardly any clothes, Roller's pupils were very seldom cold. That was because their bodies were full of energy which they got from the sun. But the doctor knew that sunshine can also be dangerous. If, for example, tuberculosis is attacking the lungs, unwise sunbathing may do great harm. Today there is not just one school in the sun. There are several in Switzerland, and since Switzerland is not the only country which has the right conditions, there are similar schools in other places. According to the passage, when did sunlight begin to play a more important part in the treatment of disease? | [

mmlu_train_84997 | Sometimes people are not clear about what kind of food is healthy, and what kind of food may do harm to our health. The USDA has prepared a food guide to help people learn about which kind of food is the healthiest to eat. The food guide describes six main food groups: meat (like fish and chicken), dairy (like milk and cheese),grains (like bread and rice), fruit and vegetables. The last group is fats and sweets. The USDA also suggests how much of each food group is healthy to eat daily. Though this guide was prepared by the US government, it is very useful for people all over the world. As a _ of years of study, we know that too much animal fat is bad for our health. For example, Americans eat a lot of meat and only a small amount of grains, fruit and vegetables. Because of the way they eat, they have a high rate of cancer and heart disease. In Japan, people eat large amounts of grains and very little meat. The Japanese also have a very low rate of cancer and heart disease. The Japanese live longer than anyone else in the world. However, when Japanese people move to the US, the rate of heart disease and cancer goes up as their eating habit changes. And as hamburgers, ice creams and other high-fat foods become popular in Japan, the rate of heart disease and cancer is going up there as well. People are also eating more meat and dairy food in other countries, in which the disease rate is going up along with the change of the way people eat. Doctors everywhere suggest people eat more grains, fruit and vegetables and less meat and dairy food. Eating healthily is important for children as well as their parents. When parents have poor eating habits, their children usually do, too. After all, children eat in the same way as their parents. When parents eat healthy food, the children will learn to enjoy it, too. Then they will develop good eating habits. Doctors suggest parents give their children healthier food such as fruit, vegetables and juice. Everyone wants to live a long, healthy life. We know that the food we eat affects us in different ways. For example, doctors believe that fruit and vegetables can really protect people from many different diseases. On the other hand, animal fat can cause diseases. We can change our eating habits now and enjoy many years of healthy living. What is the USDA in the passage? | [

mmlu_train_16518 | Doctors in hospital emergency rooms often see accidental poisonings . A frightened parent arrives with a child who swallowed a cleaning liquid. Or perhaps the harmful substance is a medicine. Or it might be a chemical product meant to kill insects. These are common causes of accidental poisoning. In cases like this, look for medical help as soon as possible. Save the container of whatever caused the poisoning. And look on the container for information about anything that stops the effects of the poison. Save anything expelled from the mouth of the victim. That way, doctors can examine it. In the past, some people forced poisoning victims to empty the stomach. They used a liquid syrup of ipecac to do this. But an organization of children's doctors no longer advises parents to keep syrup of ipecac. The American Academy of Pediatrics says some poisons can cause additional damage when they come back up the throat. Millions of people know a way to save a person who is choking on something trapped in the throat. The method is commonly known as the Heimlich Maneuver or abdominal thrusts. The American Red Cross says a rescuer should first hit the person on the back five times between the shoulder bones. These back blows may ease the choking. If the airway is still blocked, the Red Cross suggests pushing hard five times along the victim's abdomen. The abdomen is the area between the chest and the hip bones.

mmlu_train_6392 | Do you suppose Darwin, one of the greatest scientists of all time, really did fools' experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish? Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important. Charles Darwin didn't settle for just thinking he knew something. And, he believed all things could be important however simple they seemed to be. Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn't be worth anything. But this simple experiment is important. It explains part of our present day understandings of physics ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.

mmlu_train_8010 | You may think your bathroom is often full of bacteria and so you give it a complete cleaning once a week. But how often do you clean out and disinfect your fridge? Well, probably not often enough, according to a recent study, which found out that the fridge is the second dirtiest place in your house, just behind the bathroom. Fridge temperatures were often set too high, allowing the growth of bacteria, which included E.coil, Enterobacteria, and S. aureus, all of which will give you an easy access to food poisoning. So what can you do to ensure your fridge---and your food in it---is not a health threat? For starters, clean the fridge weekly---wipe it and repeat. Make sure your fridge is at the correct temperature for storing food, between 0 and 5 degrees centigrade. Your freezer should be below-18 degrees centigrade. You can use fridge and freezer thermeters to make sure this is the case. Some modern fridges have zones to store different types of food ,such as meat and vegetables. Make sure you don`t store meat in the vegetable zone, as the temperature there might be higher. Make sure you don not leave the door open too long as the temperature in the fridge will quickly rise, creating a breeding ground for bacteria. Cover food that has not been finished, and eat it within a couple of days. Keep bottles and jars closed. Keep raw meat away from cooked meat. Both should be well covered to prevent pollution. Store raw meat at the bottom of the fridge to stop juices dripping onto other foods. Finally, use common sense, and throw away old food.

mmlu_train_59673 | Space travel is definitely bad for astronauts' bones, reducing their bone density after only a month of weightlessness, according to French research published on Friday. Laurence Vico and his fellow workers at St Etienne University called for more research into the effects of microgravity, after their study of 15 astronauts from the Russian MIR station showed bone loss continued throughout space flights. "Bone loss was especially striking in four astronauts, " the scientists reported in the Lancet Medical Journal. They measured the bone mineral density (BMD) of bones in the forearm and lower leg of the astronauts who had spent one to six months in space. The BMD loss was significant in the tibia of the lower leg, a weight-bearing bone, but barely changed in the radius of the forearm. "Our results indicate the need to investigate not only different bones, but also different areas of the same bone since not all sites of the skeleton are similarly affected by space conditions, " they added. Without gravity the body isn't bearing any weight so there is no need for calcium which makes bones strong, and it becomes empty into the bloodstream. The research team suggested in future scientists should try to determine if the loss of bone density was only on weight-bearing bones on longer flights, also the possible recovery after returning to Earth. Scientists have found that _ . | [

Men and women in France are seeking relief using the world's best medicine-----laughter. In the past year, more than 15 laughter clubs have been set up across the country. People of all ages go to release their stress with an hour group laughs. "People telephoned me and said they have forgotten what it is to laugh. They want to find a place where they can escape all their problems for a while. So they come," said 40--year--old Jocelyne Le Moan. She usually takes a class of around 60 people through a series of laughter techniques. Her pupils range from teenagers to 70 years old, but most are middle---aged white collars seeking 60 minutes of relaxation at the end of a busy day. Le Moan takes them through the "Lion Laugh"and the "Laugh Contest", where participants "speak"to each other in different ways. And instead of talking, they break into fits of laughter. At the end there are 15 minutes of "meditation", when they lie on their backs and let the laughs burst out of their mouths. "I love it. It's an experience that has changed my life. Through it I rediscovered the child's laugh inside me,"Said Romain Jouffroy, 24. "US President George W. Bush should give it a try. He has lost his laugh,"she joked . Like Jouffroy, many laughter club members find themselves changed into children again, and why not ? The average preschooler laughs up to 400 times a day. The average adult only a day seven to 15. The physical benefits of laughter are already well--recognized. Doctors say the act of laughing releases good chemicals into the blood--stream, while the quick breathing that accompanies it helps massage the digestive organs and strengthens the heart. "A full hour is like having your inside go jogging!One finishes out of breath, but feels revitalized(.

mmlu_train_27450 | For centuries, medical pioneers have refined a variety of methods and medicines to treat sickness, injury, and disability, enabling people to live longer and healthier lives. "A salamander (a small lizard-like animal) can grow back its leg. Why can't a human do the same?" asked Peruvian-born surgeon Dr. Anthony Atala in a recent interview. The question, a reference to work aiming to grow new limbs for wounded soldiers, captures the inventive spirit of regenerative medicine. This innovative field seeks to provide patients with replacement body parts. These parts are not made of steel; they are the real things --- living cells, tissue, and even organs. Regenerative medicine is still mostly experimental, with clinical applications limited to procedures such as growing sheets of skin on burns and wounds. One of its most significant advances took place in 1999,when a research group at North Carolina's Wake Forest Institute for Regenerative Medicine conducted a successful organ replacement with a laboratory-grown bladder. Since then, the team, led by Dr. Atala, has continued to generate a variety of other tissues and organs from kidneys to ears. The field of regenerative medicine builds on work conducted in the early twentieth century with the first successful transplants of donated human soft tissue and bone. However, donor organs are not always the best option. First of all, they are in short supply, and many people die while waiting for an available organ; in the United States alone, more than 100,000 people are waiting for organ transplants. Secondly, a patient's body may ultimately reject the transplanted donor organ. An advantage of regenerative medicine is that the tissues are grown from a patient's own cells and will not be rejected by the body's immune system. Today, several labs are working to create bioartificial body parts. Scientists at Columbia and Yale Universities have grown a jawbone and a lung. At the University of Minnesota, Doris Taylor has created a beating bioartificial rat heart. Dr. Atala's medical team has reported long-term success with bioengineered bladders implanted into young patients with spina bifida (a birth defect that involves the incomplete development of the spinal cord). And at the University of Michigan, H. David Humes has created an artificial kidney. So far, the kidney procedure has only been used successfully with sheep, but there is hope that one day similar kidney will be implantable in a human patient. The continuing research of scientists such as these may eventually make donor organs unnecessary and, as a result, significantly increase individuals' chances of survival.

mmlu_train_7639 | In a recent study, researchers have estimated the energy required to produce bottled water, including the energy required to manufacture plastic, make the plastic into bottles, process the water, fill and seal the bottles, transport the bottles, and chill the bottles for use. Combining all the energy input totals for treatment and distribution, researchers found that producing bottled water requires between 5.6 and 10.2 million joules of energy per liter, depending on transportation factors. That's up to 2, 000 times the energy required to produce tap water. To break down the energy requirements, researchers found that producing the plastic bottles and transporting the bottles greatly dominated the energy input. Although some companies are experimenting with producing lightweight bottles or using recycled materials, the researchers calculated that the manufacturing cost is about 4 million joules of energy per plastic bottle weighing 38 grams, and the cap weighing 2 grams. "Our previous work had suggested that bottled water production was an energy intensive process, but we were surprised to see the results, " the researchers said. Transportation costs vary depending on the distance and mode of transport and both factors depend on the type of bottled water. There are two main kinds of bottled water in the US:"spring water" which comes from an underground spring and "purified water",which is city tap water that has received further treatment. For purified water distributed locally by truck within Los Angeles, the total transportation energy is about 1.4 million joules per liter. In the second situation, spring water shipped from Fiji (such as Fiji Spring Water) across the Pacific to Los Angeles, and then delivered locally by truck requires about 4 million joules per liter for transportation. For the spring water, the transportation energy equaled (in the case of Fiji) the energy required to produce the bottle. With this data, the researchers hope that future studies will have the ability to make specific estimates for different situations, and possibly find ways to cut energy costs. To reduce the energy required to produce bottled water, some companies are trying _ . | [

mmlu_train_84009 | We know that many animals do not stay ill one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but others move to get away from places that are too crowed. When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration is probably the migration of the fish, which is called "salmon" . This fish is born in fresh water but it travels many miles to salt water. There it spends its life. When it is cold, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mouse. They leave their mountain homes when they become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea. Recently, scientists have studied the migration of a kind lobster . Every year, when the season of bad weather arrives, the lobster get into a long time and start to walk across tile floor of the ocean. Nobody knows why they do this, and nobody knows where they go. So, sometimes we know why humans and animals move from one place to another, but at other times we don't. Maybe living things just like to travel. ,. The lobster move _ . | [

Bea was diagnosed with this disease when she was five months old. Since then, the hospital has become her second home, medicines for food, and all kinds of treatments her friends. Bea received a very special treatment when she was four years old, which would allow her to be like a normal child if successful. After that, she spent two weeks in ICU before living for four months on a separate ward . Bea was allowed home in February but still needed a special tube in her nose to send in medicines every two days. Her parents clean the house from top to bottom every two days and hoover each morning to make sure Bea is free from any possible bacteria. Anna, Bea's mother, said, "she is weak but so strong. We've never seen any child stronger than her. It seems as if nothing in the world could beat her. We really hope to send her to school next year." She used to drive on the local playground, but Bea was only allowed to watch sitting in the car. "It was heartbreaking to see Bea staring at the running and laughing children there. She never stopped fighting the disease. I know she's dying for such a normal life." Hearing of Bea's story, the Make-A-Wish Foundation has paid for a play park to be built in her back garden.

mmlu_train_55041 | It seems like every day there's some new research about whether our favorite drinks are good for us. One day, science says a glass of red wine a day will help us live longer. The next day, maybe not. It seems journalists are pretty interested in wine research and the same might be said for coffee. Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed",admits Neal Freedman who led the coffee study and published his findings in a medical journal recently. "There's been some evidence that coffee might increase the risk of certain diseases and there's also been maybe more recent evidence that coffee may protect against other diseases as well". Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400,000 Americans ages 50 to 70 participating in the study. "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers, he said. Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease injuries, accidents and infections. Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.

mmlu_train_37865 | You're in your office when you learn there's someone with a gun wandering outside. You can hear gunshots and screams. What do you do? That's the challenge for users of a new virtual reality program called SurviVR, designed to train employees how to deal with an active shooter situation in the workplace. The program works with HTC Vive, the virtual reality headset released earlier this year. An active shooter situation is when an armed person or people actively shoot in a small, populated area with the intention to kill. There were 20 such situations in the United States last year and 20 the year before, according to FBI statistics, resulting in a total of 231 deaths. This year saw the deadliest active shooter situation in US history , with 49 people killed in a nightclub in Orlando. In the training situation, users have four choices. They can lock themselves in the office. They can hide, perhaps in the office closet. They can run for an exit. Or they can use something in the office--a computer or a cup a pair of scissors-as a weapon to fight the shooter. This is an improvement on standard active shooter training. Gallo says, which typically teachers people to lock themselves in place and hide. The "lock down" method is often ineffective, he says, and has resulted in many deaths in recent years. In the training's basic level, no one gets killed. But as the trainings become more advanced, players who make a wrong choice be shot. There's no blood; the screen simply turns black slowly. If this sounds terrifying, that's the point, says Gallo. There are plenty of training programs to teach employees how to deal with workplace violence, sometimes involving role play with toy guns. But these trainings are basically games. Gallo says, with employees relaxed and even enjoying themselves. To teach people what they really need to know for an active shooter situation, they need to be scared. "SurviVR will take the fear and turn it into confidence." Gallo says.

mmlu_train_10357 | Thousands of people in the world are a hundred years old - or more and certain parts of the world are famous for the long lives of their inhabitants: the Vilacamba Valley in Ecuador, and the home of the Hunzas in the Himalayas. Why do so many people live to a healthy old age in certain parts of the world? What is the secret of their long lives? Three things seem to be very important: fresh air, fresh food and a simple way of life. People work near their homes in the clean mountain air instead of traveling long distances to work by bus, car or train. They do not sit all day in busy offices or factories, but work hard outdoors in the fields. They take more exercise and eat less food than people in the cities of the West. For years the Hunzas of the Himalayas did not need policemen, lawyers or doctors. There was no crime, no divorce and not much illness in their society. They were a happy, peaceful people, famous all over India for their long, healthy lives. Do you want to live to a hundred years old? Here are some rules for success. First, live in the right place. Second, choose the right kind of job. Doctors, dentists and bus-drivers die young. Farmers, priests and orchestral conductors live much longer. If you are in the wrong kind of job, you can still improve your way of life. An old man in the Caucasus was talking about his past life. "I was young then," he said, as he described his 87th year. His secret was: "Think young and stay young." An old woman from Missouri, the USA, gave this advice, "Drink a little whisky and some warm beer every day." An English lady just said, "Take a cold bath every morning." The shortest, simplest piece of advice came from Mr Jim Chapman, aged 103. "Just keep breathing," he told reporters.

Professor Worm says species have recently been disappearing from oceans at increasing speed. At this rate, he says, all seafood species could collapse by 2048 and seafood supplies from the world's ocean could be almost gone by then. Other studies have also warned about the dangers of overfishing and the effects on ocean environments. But not everyone thinks the oceans are likely to be empty in fifty years. Some scientists said parts of the world do have problems, but others are doing a good job of protecting fish populations. Government officials in several countries with large fishing industries also questioned the research. The study appeared earlier this month in Science magazine. The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems. These complex systems help control water quality. The scientists say the loss of different kinds of sea life appeared to increase the risk of fish kills and beach closures from harmful algae growth. The scientists examined the results of thirty-two experiments and observed forty-eight protected areas. They also looked at records of catches worldwide.

Most animals must live in a group, and even a plant grows close together with others of the same kind. Sometimes one living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they create a food chain . Some food chains are simple, while others are not. But all food chains begin with the sun, and all food chains become broken up if one of the links disappears. All life needs sunlight to live on. But only plants can use sunlight directly. Plants are 'factories'. They make food from sunlight, water and things in the soil and air. Plants feed all other living things. Animals can only use the sun's energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly. What about humans? We are members of many food chains. We eat rice, vegetables, and fruits and so on. We also eat meat and drink milk. But we often break up the food chains. We kill wild animals and also make rivers, lakes and seas polluted. When these rivers, lakes and seas are polluted, the fish in them can not be eaten. If we eat the fish, we will get strange illnesses. Each form of life is linked to all others. Breaking the links puts all life in danger. Which living things can use the sun's energy directly? | [
