mmlu_train_68860 | In the sunny night, look up at the clear night sky. You can probably see thousands of stars. The biggest thing you'll see, of course, is the moon. For thousands of years, people have wondered about this big thing in the sky. Earth's moon is a satellite. A satellite is a body that orbits a planet. All moons are satellites, and many planets have them. Some have many moons. Earth, of course, only has one. It's a special moon, though. It's the fifth largest moon in the solar system! In fact, the moon is much smaller than the sun. But it's much closer to Earth, so it looks as big as the sun. The moon is so close that you can see its dark and light spots without a telescope. Men flew and landed on the moon's surface many times by spacecrafts in the 1960s and 1970s. Neil Armstrong was the first human to step on the moon. He walked on the moon on July 20th, 1969. The flights to the moon have helped us learn much about it. Astronauts even brought rocks home with them! There's still a lot to learn about the moon. Now people still can't live on the moon because it does not have oxygen or water like the Earth. But I'm sure that humans can live there one day in the future. ,. What is a satellite? | [

mmlu_train_12394 | A new planet-hunting technique has detected the most earth-like planet yet around a star other than our sun, raising hopes of finding a space rock that might support life, astronomers reported recently. "This is an important discovery to answer the question 'Are we alone?'" said Michael Turner of the National Science Foundation. "The team has discovered the most earth-like planet yet, and more importantly, has proved the power of a new technique that is sensitive to detecting planets that are fit for people to live on," Turner said in a statement. In the last decade, astronomers have detected more than 160 planets moving around stars outside our solar system. Most of these have been gas giant planets like Jupiter, which are unfit for life. But an international team has detected a cold planet about 5.5 times more massive than the earth -- still small enough to be considered earth-like -- moving around a star about 20,000 light years away, close to the center of the Milky Way. To find this new planet, the team used a technique called gravitational microlensing . When a planet is circling the closest star, the planet's gravity can add its own signature to the light. This kind of light signature was observed on July 11 by a group of telescopes in a project known as OGLE, short for Optical Gravitational Lensing Experiment. "The main advantage of microlensing is the signals for low-mass planets: They're not weak signals. They're just rare," Bennett of the University of Notre Dame in Indiana said by telephone. "If there happens to be a straight line between a foreground star with its planet and the background source star, then you're able to detect that planet."

mmlu_train_52587 | Watching the Olympics probably made some people feel a little guilty about not exercising.The truth is that, if physical inactivity were a sport, a lot of us could give a gold-medal performance.Or should we say non performance? Public health experts say physical inactivity is the world's fourth leading cause of death. They estimate that inactivity plays a major part in six to ten percent of deaths from non-communicable diseases. These include conditions like heart disease, diabetes, and colon and breast cancer. Min Lee at the Harvard School of Public Health worked with a team that studied inactivity. She says the findings are conservative and may even underestimate the problem and that Physical inactivity is harmful to health, as harmful as far as deaths are concerned as smoking." So when we did our analysis, we looked at increased risk of disease after taking into account other health habits that might be associated with physical activity. For example, we know that if you are active, you probably smoke less. Additionally we factored out obesity, independent of the fact that active people also tend to weigh less. The researchers compared data on physical inactivity with disease rates in one hundred twenty-two countries. They find high income countries are the most inactive around the world, but low to middle income countries are not going to be far behind as things change, as their economies improve and their people rely more on the improvements that basically engineer physical activity out of our daily lives. It is not just telling someone to go out and be physically active, but how we rely on the transportation sector or how our cities or neighborhoods are designed, how crime can be minimized to help people become more physically active in their neighborhoods, simply walking to the store or walking down and being outside with friends and family and so on. These broader environmental issues are becoming much clearer in terms of their effects. When watching the Olympics, some people may feel sorry because of _ . | [

mmlu_train_5447 | Health insurance can be very expensive. Some working people do not make enough money to pay for it. In the US there is a program called Healthy Families. This program offers people health insurance at a low cost. Families are charged about Y=7.00 a month for every child, and Y=10.00 for every adult. It costs much less than any other kind of health insurance. Having health insurance is very important. With this insurance, people can see a doctor when they are sick or hurt. The program is not expensive at all, but many people are still not enrolling in it. People say that it still costs too much money. They need all of their money to pay for things like food and rent. It would be great if everyone could have health insurance. People are working hard to come up with ways to make this happen. One idea is to make the Healthy Families Program free for some people. It is important for people to see a doctor when they need to. The Healthy Families Program makes it possible for more people to do this. Many ideas are being considered. Hopefully some of them will allow even more families to get health insurance. The Healthy Families Program is made to help those who don't have welfare and cannot earn enough to pay for private health insurance. It is an important program, but officials say that too many people are signing up for it and then dropping out because of the Healthy Families Program's cost.

mmlu_train_20557 | NEW YORK (Reuters Health)--Kids who eat better perform better in school, a new study of Nova Scotia fifthgraders confirms. Students who ate an adequate amount of fruit,vegetables,protein,fiber and other components of a healthy diet were significantly less likely to fail a _ test,Dr.Paul J.Veugelers of the University of Alberta in Edmonton and colleagues found. While a healthy diet is generally assumed to be important for good school performance, there has actually been little research on this topic, Veugelers and his colleagues note.To investigate,they looked at 4, 589 fifthgraders participating in the Children's Lifestyle and Schoolperformance Study, 875 (19.1 percent) of whom had failed an elementary literacy assessment. The better a student's eating habits based on several measures of diet quality,including adequacy and variety, the less likely he or she was to have failed the test, the researchers found,even after they adjusted the data for the effects of parental income and education, school and sex.Eating plenty of fruit and vegetables, and getting fewer calories from fat, was also associated with a lower risk of failing the test. To date, Veugelers and his team say, most research on diet and school performance has focused on the importance of eating breakfast, as well as the ill effects of hunger and malnutrition . "This study extends current knowledge in this area by demonstrating the independent importance of overall diet quality to academic performance.We should not only realize the importance of children's nutrition at breakfast but also that throughout the day," the researchers conclude. Another research from the UK is suggesting that children's diets in the preschool years affects how they perform at school later on.The researchers from the Institute of Education, at the University of London say in fact that what children were eating in those days before primary school has more of an effect than the chicken nuggets they ate at lunchtime.The researchers say they have found that children who ate a diet of "junk food" at the age of three, made less progress in school between the ages of six and ten.They say children's diet at later ages appears to have less impact on their school attainment. .According to Dr.Paul J.Veugelers, students who have a healthy diet _ . | [

mmlu_train_37066 | Astronomers recently found another ring around the planet Saturn -- and it's the biggest one yet. This newly discovered ring stretches about 15 million miles across, which makes a loop big enough to fit a billion Earths inside. It may be even bigger and reach 22 million miles across at its diameter . Saturn's new ring is now the biggest known ring in the solar system. This ring, like Saturn's other rings, is not one solid piece of rock. Instead, it is made up of millions or billions of tiny rocks that orbit the planet all together and give the appearance of a unified ring. Unlike the more visible rings, however, this big one is mysterious -- the pieces are far apart, and the ring cannot be seen from the surface of the Earth. If all the pieces were stuck together, they'd be slightly bigger than a rock a half-mile wide. Astronomers suspect that the newly discovered ring gets its material from Saturn's outermost moon, Phoebe. For example, the dust in the ring circles Saturn in the same path and the same direction as Phoebe. Plus, the surface of Phoebe is marked with holes and places where rock has been knocked away, the result of collisions between Phoebe and other moons and rocks. These collisions could have sent dust out into space to become part of the big ring. The discovery of the ring could help explain other mysteries surrounding Saturn and its dozens of moons. The moon called Iapetus, for example, is two-toned: one side is gray; the other more reddish. Iapetus is within the newly discovered ring, but it orbits in the opposite direction. As a result, some researchers say, debris from the ring may have coated and color1ed one side of Iapetus as it moved through space, and left the other side alone. "The cause of Iapetus' strange color1 distribution ... has been a puzzle that now seems solved," said Joseph Burns, a scientist. But not everyone agrees. Some think the ring alone may not be able to explain Iapetus' funny color1ing. The rocks of the newly discovered ring may be from _ . | [

mmlu_train_58294 | Keeping fish as pets is a popular hobby. Fish take up little room, are inexpensive to feed, and provide an interesting and color1ful display in any room. A tank, or an aquarium , must be chosen carefully. Many new aquarium owners buy too many fish for their tanks. Fish cannot be crowded. Two fish can live comfortably in each gallon of water, only ten fish can live in a five-gallon tank. Can you see why a goldfish would not live long in a tiny , round bowl? If too many fish are kept together, they will not have enough oxygen or room to swim about freely. They will have more diseases. Also, some kinds of fish cannot be kept together. They will fight and may even kill one another. As your interest in fish grows, the number of fish you have may grow, too. Then you may want to _ in another tank. If you start with a ten-gallon aquarium, what kind of fish would be best? The two major groups of tropical fish are those that lay eggs and those that give birth to live young. If you want to raise young fish, guppies would be the best choice because they can produce many babies in a short time. You can buy fish and aquariums in most pet stores.

mmlu_train_41021 | How did a ban on smoking in public places come into place? In 1998 the Smoking Kills White Paper set out a national strategy to reduce smoking prevalence and passive smoking, including in public places. The measures were voluntary and poorly carried out. After a public conference in England in 2004, the Government decided to choose for lawmaking. Scotland went first, with a ban in 2006, followed by the other nations a year later. What is the current law? Any person who smokes in enclosed public places, including pubs, offices, on public transport and work vehicles, is breaking the law. It does not extend to private houses. It is also an offence for people in charge of premises to permit others to smoke in them. How was it received? It was welcomed by most organizations except for some pub owners and restaurateurs. Many workplaces in the UK had already introduced smoke-free policies consistent with the legislation (,) before it was carried out, while others have gone beyond its basic requirements. All railway facilities, including platforms, footbridges and other areas--whether or not fitting the definition of an enclosed public space--are covered, as are all football grounds and some cricket and athletics stadiums. School grounds are not required to be smoke-free under the legislation, but the majority now are. How has it been forced? Compliance in public premises has been high, with inspections suggesting that 99 per cent of places were sticking to the rules. The number of people charged for smoking in cars has been very low, which was due to the problems defining and identifying "work" vehicles. They said that a total ban on smoking in vehicles would end this confusion. Has it improved health? Studies in early adopters of the law, including in Scotland, suggest a reduction in hospital admissions for heart disease, which has been shown to be linked to passive smoking. There is also strong evidence of improved rates of smoking end and a drop in the number of cigarettes consumed by those who continue to smoke. Who might feel unhappy about the law according to the article? | [

Mobile communications account for 28.5 percent of the total long-distance communications business. IP phones have 41.4 percent, while traditional long-distance calls are down to 30.1 percent. China Mobile, the country's largest mobile communication operator, has accounted for nearly 40 percent of taxes in the domestic telecom market. That puts it at the top of the six major telecom operators in the nation, according to the latest official statistics. The other five are: China Telecom, 31.1 percent; China Netcom, 16.6 percent; China Unicom, 13.4 percent; China Satellite Communications Corp and China Railcom, 1.5 percent. China Mobile is being chased by smaller rivals China Unicom and China Telecom, both of which are making significant 3G subscriber gains. That's aided in no small part by deals to offer the iPhone. However, as of March, China Mobile did have 15 million iPhone users on its network. In another ranking, Xiaomi, Huawei, Lenovo, vivo and OPPO came in as the top five mobile phone sellers in China by April, 2015, according to IHS Technology. The report also says that during this period, China produced 82 million handsets. (including GSM, GPRS and CDMA phones) and sold 80 million. Of the phones sold, 37 million were exported to other countries. Analysts point out that China's lack of core technologies and its heavy reliance on overseas technologies have proved to be an obstacle for development of domestic phone makers.

mmlu_train_38255 | Edward Wilson The Future of Life, . Edward Wilson is America's, if not the world's, leading naturalist. In The Future of Life, he takes us on a tour of the world's natural resources . How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity of our earth. Wilson begins with an open letter to the pioneer in environment protection, Henry David Thoreau. He compares today's Walden Pond with that of Thoreau's day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Van the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future? Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas. At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas in this book. We learn from the text that Wilson cares most about _ | [

mmlu_train_54643 | Scientists have created a " human-like robot" that can dance and do the housework. " Mahru" has been developed to imitate humans and can move its lips, eyebrows and pupils . The machine can also move its upper and lower body freely and automatically stop itself when walking. In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions. The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind. "'Mahru' will open the way for the commercial use of humanoid robots doing housework," You Bum-Jae, leader of the development research team ,said. "'Mahru' can dance while walking on its legs and is able to work in place of a human." Through an advanced motion capture system, "Mahru" can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking. State-funded KIST showed the robot during a presentation at its head office in Seoul. People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves. The research team added that they had designed another " Mahru", this time with sensors allowing it to distinguish between faces and objects. The showing of " Mahru" came a week after researcher in Japan said they had created the "most human-like" robot in the world. A team at robotics department of Osaka University in Japan claimed that " robogirl", Repliee R-1, " looks, moves and interacts like a human, and has silicone skin that feels almost human to the touch."

mmlu_train_58688 | A developer edition of Sony's augmented reality smart glasses will go on sale in ten countries next month, the tech giant has announced. Pre-orders for the SmartEyeglass, costing $840 (PS620), are now being taken in the UK and Germany, with Japan and the US to follow shortly. The black-framed glasses are compatible with recent Android operating systems. Last month Google announced that it was withdrawing its smart glasses for redevelopment. Sony's initial model will come with a software development kit to encourage people to design apps for it, the company said. The glasses, which weigh 77g, contain an accelerometer, gyroscope, compass, image and brightness sensors, 3-megapixel camera and a microphone. They also come with a controller, designed to be attached to clothing, which contains a speaker, touch sensor and the device's battery. Text is displayed in front of the wearer in monochrome green. Apple chief executive Tim Cook has been open about his dislike of glasses as a wearable device. "We always thought that glasses were not a smart move, from a point of view that people would not really want to wear them," he told the New Yorker. "They were intrusive , instead of pushing technology to the background, as we've always believed." Stuart Miles, founder of tech site Pocket-lint, said: "I think [Sony is] wasting their time, energy and effort." "Google Glass obviously needed a complete rethink... I can't see how something thick-rimmed and more invasive-looking than Google Glass is going to catch on. "People are keen on wearables like fitness bands and watches, but they care about their faces. Wearing something on your head is a lot stronger than wearing something on your arm," he added. "The industry keeps pushing it but consumers just don't want it."

mmlu_train_34114 | If a noisy neighbor is blasting music at all hours of the day and night, drowning out your phone conversations and interrupting your sleep, you can call the police. But what is a whale to do? Natural noise from waves, wind, rain and even earthquakes is common in oceans. Unfortunately, man-made noise from oil and gas drilling, sonar, and ships is also present. Low frequency noise has doubled off the California coast every decade since the nineteen sixties. The main reasons are ships' propellers . They not only generate continuous low frequency sound, some propellers cavitate , which means they create air bubbles that collapse, creating loud popping sounds. Whales use low frequency calls to communicate across thousands of miles of ocean. They are threatened by noise pollution because it can prevent them from contacting each other and from locating their foods. Endangered humpback and right whales, which use fibrous baleen to strain food from the water, are the most at risk. Scientists studying right whales off Canada's east coast have discovered that whales are sending louder calls through the water to make themselves heard. Because they invest more energy in making calls, they have less energy available for finding food and mating. Other scientists measuring whale calls against background noise pollution have discovered that right whales have lost about eighty percent of their normal communication area. This could seriously affect survival of this already threatened species. Scientists don't have badges and guns, but they are trying to correct the noise pollution problem. By tracking ships and marine mammals and understanding how noise travels, they are creating sound maps. They hope to get shipping lanes moved so that the noise pollution ships create will not overlap with areas most important to the whales. According to the description of whales, we can know that _ . | [

mmlu_train_30227 | Ever since they were first put on the market in the early 1990s, genetically modified (GM, ) foods have been increasingly developed and marketed in many countries in the world, mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would, is it the best solution? Despite what it promises, GM technology actually has not increased the production potential of any crop. In fact, studies show that the most widely grown GM crop, GM soybeans, has suffered reduced productivity. For instance, a report that analysed nearly two decades of research on major GM food crops shows that GM engineering has failed to significantly increase US crop production. Something else, however, has been on the rise, While GM seeds are expensive, GM companies tell farmers that they will make good profits by saving money on pesticides . On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. "The promise was that you could use less chemicals and _ production. But neither is true," said Bill Christison, President of the US National Farm Coalition. At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report. As a matter of fact, scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which "green" farming is supposed to be the first choice.

mmlu_train_13305 | As if there weren't enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic stem cells. In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly 'reprogrammed'. Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos might be grown in selected solutions that change the activity of those genes to improve the technique's success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics. The failure of most cloned animals is due to _ . | [

mmlu_train_72610 | ARE you creative, shy, outgoing? Our personalities reveal a lot about who we are. But what's surprising is that our personality can also say something about our health. That's according to researchers at Duke University, US. During an experiment on 1,000 people, scientists assessed their personalities in two ways: by asking someone they knew, such as a family member or friend; then by asking someone they had just met, such as a nurse. The study found that those who were careful at age 26 were in better health after 12 years. Being careful means that people tend to have a lot of self-control, and are less likely to smoke, the scientists said. Careful people are also more likely to have an active lifestyle and healthy diet. From those who were least careful, 45 percent developed health problems by the age of 38. Such health issues included gum disease and high blood pressure . To compare, only 18 percent of careful people went on to develop health problems. Another positive personality was called "openness to experience", meaning curious and imaginative. People who have more of this personality have higher IQ scores. So they'd be more likely to know how to find medical help to prevent disease. According to the report, if doctors assessed our personalities, it could help doctors to find which young adults need advice on how to live a healthy lifestyle. What's surprising is that stress didn't play a big part on a person's health. Even though stress and anxiety are usually linked to bad health. But can a doctor who knows our personality really improve our health? Or should doctors be kept away from knowing something so personal? Where can you probably read the article? | [

People have enjoyed dancing for a very long time. This story is of a different kind of dance. It is a dance without people or music. Yet this dance is one of the oldest in the world. It is the dance of bees. If you have ever watched bees, you know that they are very clever. They also work hard looking for food and bringing it back to their home. The home of the bees is called a bee hive. Here hundreds even thousand of bees live. They work day and night building small walls. There they make their honey. This is the same honey that we eat. Where does the honey come from? Bees live on food from flowers. Have you seen bees flying around a flower garden? When a bee rests on a flower, it tries to go to the centre of it. There it takes in as much food as its body can hold. Then it flies to take the food back to the hive. At the hive, bees change flower food into honey. Then they fly away for more food. How do the bees know where to find the best food in the sweetest flowers? One bee acts as a guide. When it discovers good flowers, it flies back to the hive and tells the others. It does this by dancing for them. The bee dances on one side. This tells the other bees which way to go to find the flowers. But that is not all. The bee dances for some time. And the length of its dance tells the other bees how far they must fly to reach the flowers. When the bees see the dance, they know where the flowers are. They fly away and return with more food for the hive. Sometimes we hear the music of the bees as they fly around. But few people have ever seen them dance. Yet without that dance we might never have sweet honey to eat. What character do bees have? | [

Parents who lose children in accidents may be able to clone "copies" to replace them then. Although any attempt to clone an entire human would raise complex moral issues, the biologist claimed people would soon overcome their concerns if the technique became medically useful.Cloning was regarded with extreme doubts when it was first developed but became widely accepted after the birth of Louise Brown, the first "test tube baby" He said, "When my first frog experiment.s were done, an American reporter asked how long it will be before these things can he done in mammals or humans I said, 'Well, it could be anywhere between 10 years and 100 years-how about 50 year ?' It turned out that it wasn't far off the mark as far as Dolly was concerned.Maybe the same answer is appropriate." Sir John added that cloning a human being effectively means making an identical twin, and doctors would therefore simply be "copying what nature has already produced" The average vote on allowing parents of deceased children, who are no longer fertile , to create another using the mother's eggs and skin cells from the first child, thinking the technique was safe and effective, is 60 per cent in favor.The reasons for "no" are usually that the new child would feel they were some sort of a replacement for something. .

Just to be clear, those were not 253 calories' worth of tofu, yogurt or carrot.The most popular vending machine items included soft drinks, candy, chips, crackers, cookies, cakes and ice cream.On the plus side , kids also bought low-fat milk, fruit juice and even fruit, the study found. But the eventual effect on kids' diets was not good.Those who bought from vending machines ate an average of 156 grams of sugar per day, compared with 146 grams for those who abstained .They also consumed less fiber, iron and vitamin B. _ Vending machine customers ate 4% less sodium than other students--an average of 3,287 milligrams per day compared with 3,436 mg for those who didn't buy from vending machines.That's probably because the extra snacks made kids too full to eat as much at mealtimes, when dishes are especially Salty.In any event, kids should eat no more than 1,200 to 1,500 mg of sodium each day, according to the Mayo Clinic.Even for adults, the government recommends a daily limit of 2,300 mg. Overall, vending machines in school appear to be a threat to children's health.The researchers calculated that all that snacking adds up to about14 extra pounds per child per school year.For some students this might be a serious contributor to weight issues.The study was based on data collected from 2,309 children nationwide for the third School Nutrition Dietary Assessment Study, which was conducted by the U.S.Department of Agriculture's Food and Nutrition Service.

mmlu_train_44556 | A portable lung which could help those with breathing problems lead a normal life is being developed by scientists. The Swansea University scientists say it could take many years before the device , the size of a spectacle box , is available . Lung patients , who have seen how it would work , have welcomed the research. Its research suggests that one person in every seven in the UK is affected by lung disease---- this equates to approximately 8 million people. As of 6 March 2009, 217 people were on the waiting list for a lung transplant according to figures by NHS Blood and Transplant . Now scientists in Swansea are developing a portable artificial lung which could transform the lives of patients . Researchers claim that in the long term the device could offer an alternative to lung transplant , giving hope to those who suffer from conditions such as emphysema and cystic fibrosis. The device mimics the function of a lung---by getting oxygen into and carbon dioxide out of the blood stream . Professor Bill Johns came up with the idea after his son died of Cystic Fibrosis . It is important that we make something that will help people , who instead of being confined to a wheelchair with an oxygen bottle , can actually walk around and do things for themselves , he said. Although the research has been welcomed by leading charities , caution has also been voiced over the length of time it will take before a portable lung will become available . "We have to stress that this is several years away from being used , even in a trial stage," said Chris Mulholland , head of the British Lung Foundation. Patient Elizabeth Spence from Swansea has been refused the double lung transplant she needs but remains hopeful that one day the new device could save her . " My body will reject the lungs , so this possibly could be an answer--- another way of getting new lungs without actually having the transplant," she said.

mmlu_train_9372 | When English as a foreign language is taught to children at the primary and early secondary levels of education, it is generally taught with a general education aim in mind--that is, it is regarded as a "good thing" for them to learn a foreign language as a part of a broad education. There is usually, however, no immediate and specific requirement for such children to make use of the language in any communicative situation. The purpose of learning the language is essentially a "deferred" purpose, deferred till the tertiary level of education, normally at university, where, it is agreed, a knowledge of English would be helpful in their academic studies. Immediate aims of learning English are defined by the requirements of examinations. Inevitably what is taught to primary and secondary level children is not a communicative knowledge of English language use, but a knowledge of how the rules of English operate. The language system is taught by means of systematic audio-lingual drill and exercise techniques based on habit formation theory of learning and a structural description of English. This may be an effective manner of teaching English usage, but it is less certain that an understanding of how these rules are related to language in use for communicative purpose is an automatic result of this instruction. What the thousands of children succeed in learning in this way is what is necessary in order to pass examinations. Whether such examinations accurately reflect the uses to which English will be put at the tertiary level is another matter altogether. Adults, on the other hand, unless they are learning a foreign language for "pleasure" at evening institutes, as a "cultural" and social experience, are generally highly conscious of the use to which they intend to put it. That use is frequently associated with an academic or professional requirement; without a knowledge of the foreign language, their development in their chosen sphere of work could be restricted or at least adversely affected. According to the author, the current examination system _ . | [

mmlu_train_45869 | Mouth bacteria grow fast in airless conditions. Oxygen rich saliva keeps their numbers down. When we sleep, for example, the saliva stream slows, and sulfur producing bacteria gains the upper hand, producing classic "morning breath". Alcohol drinking, too much talking, breathing through the mouth during exercise, anything that dries the mouth produces bad breath. So can stress, though it's not understood why. Some people's breath turns sour every time they go on a job interview. Saliva flow gradually slows with age, which explains why the elderly have more bad breath trouble than younger people do. Babies, however, who make plenty of saliva and whose mouths contain ly few bacteria have characteristically sweet breath. For most of us, the simple, dry mouth variety of bad breath is easily cured. Eating or drinking starts saliva and sweeps away many of the bacteria. Breakfast often stops morning breath. Those with constant dry mouth find that it helps to keep gum, hard candy, or a bottle of water or juice around. Brushing the teeth wipes out dry mouth bad breath because it clears away many of the offending bacteria. Surprisingly, one thing that rarely works is mouthwash. The liquid can mask bad breath smell with its own smell, but the effect lasts no more than an hour. Some mouthwashes claim to kill the bacteria responsible for bad breath. The trouble is, they don't necessarily reach all offending germs. Most bacteria are well protected from mouthwash under thick layers of mucus . If the mouthwash contains alcohol--as most do--it can worsen the problem by drying out the mouth. Mouthwashes are not an effective cure for bad breath mainly because _ . | [

mmlu_train_81163 | For 21 years,Georges Bwelle watched his ill father traveling to hospitals,which could not offer him all necessary help. Jamef Bwelle suffered only a broken arm at first,but it finally developed into a hematoma. That would affect him for the rest of his life. Bwelle spent years taking his father to overcrowded hospitals. It was not easy. They would leave home at 5 a.m. and ran to the hospital to be the first. There were a lot of patients. Some people could die because they were waiting. The situation hasn't changed much since Bwelle's father died in 2002. In Cameroon,there is one doctor for every 5,000 people while in the United States there is one doctor for every 413 people. And even if they could see a doctor,many Cameroonians couldn't afford it. When he saw his father and so many of his countrymen suffer,Bwelle decided to do something about it. He became a doctor himself.And he started an organization,ASCOVIME. It travels into the countryside on weekends to provide free medical care. Since 2008,he and his group of volunteers have helped nearly 32,000 people. Almost every Friday,his team jam into vans and travel to villages in need. In each trip they receive 500 people. Patients come on foot from 60 kilometers around the village for free treatment. The next morning,the team will do simple operations in a schoolhouse,town hall or home,and work into the early hours of Sunday morning. On Sunday,the team heads back to the city,tired but proud of their work. They know that their help can make a world of difference to those they help.

mmlu_train_37701 | CANBERRA (Reuters Life!) - Think twice before eating those dropped crumbs off your computer keyboard -- you might as well be eating off a toilet seat, according to a new study on the amount of germs on keyboards. A study by British "Which? Computing" asked a microbiologist to examine for bugs on 33 keyboards in a typical London office, a toilet seat and a toilet door handle. Four keyboards were judged potential health hazards and the microbiologist recommended the removal of one keyboard as it had 150 times the pass limit of bacteria -- five times filthier than the swabbed toilet seat. "Most people don't give much thought to the grime that builds up on their PC, but if you don't clean your computer, you might as well eat your lunch off the toilet," said Sarah Kidner, the consumer magazine editor of "Which? Computing" in a statement. The study found that eating lunch at desks is the main cause of a bug-infested keyboard. Dropped crumbs and food encourages the growth of millions of bacteria. Poor personal hygiene, such as not washing hands after going to the toilet, may also add to the dirtiness of keyboards. But despite the health hazard of a dirty keyboard, a survey of 4,000 people by the magazine found one in 10 people ever cleaned their keyboard while another two in 10 never cleaned their mouse. Almost half -- or 46 per cent -- cleaned their keyboard less than once a month. To clear out bugs, the magazine recommends users unplug keyboards, turn them upside down and shake them.
