mmlu_train_88448 | Almost everyone has dropped some food on the floor and still wanted to eat it.If someone saw you drop it, he or she might have shouted, " 5-second rule!" This so-called rule says food is OK to eat if you pick it up in five seconds or less.But is that true? Professor Anthony Hilton from Ashton University, UK, tested the rule with his students.They found that food dropped for five seconds is less likely to contain bacteria than if it sits there for longer. For the study, Hilton and his students tested a lot of foods----bread, pasta, cookies and candy--to see how much bacteria they had when they made contact with the floor.They allowed the food to lie on the different types of flooring--carpet , laminate and tile -- for three seconds to 30 seconds. Not surprisingly, the longer the food was on the floor, the more bacteria it had.And the type of floor where the dropped food landed had an effect.Bacteria are least likely to transfer from carpet, while they are most likely to transfer laminate or tiled surface after more than five seconds. The study also found that the wetter the food, the more likely it was to pick up bacteria.Although most people are happy to follow the 5-second rule, eating food dropped on the floor still carries an infection risk."It very much depends on which bacteria are on the floor at the time." Hilton told Forbes. According to the article, the infection risk of the dropped does NOT depend on _ . | [

mmlu_train_12351 | Since I became a full--time freelancer , I've found one of the hardest things to do is to get up early. Without the danger of being fired, there just hasn't been a lot of motivation to get out of bed. I've quickly learned that getting up is the key to success and better yet: waking up early is really just a habit. The most important thing to keep in mind is that you must have strong reasons to get out of bed. Motivation is the only thing keeping us from lying in bed all day. Writing down all the big and important things you'll do the next day can give you an extra push in your goal to wake up early and quickly. Don't read in bed. Spending as little time as possible in bed will actually help your body realize that the bed is for sleeping, and not for lying awake for hours. The goal of reading in bed is just to help you fall asleep within 10 minutes. Stress is one of the main causes of poor sleep. Relax yourself before getting into bed. Try controlled breathing exercises or yoga to lower your stress level. These are just a few ways you can use to wake up earlier. Finding the best way is the most important, and it requires a little work. The key thing is that waking up should be a pleasant experience. If you can make waking up something you are looking forward to, you're already halfway on your journey toward becoming an early riser. Which of the following is NOT true about doing yoga? | [

mmlu_train_65938 | Health experts have discovered that adding low-calorie vegetable soup to the start of a meal can actually help to lose weight. Because you feel full sooner, you eat less of your main course. The soup regime was tested by researchers at Pennsylvania State University, led by Dr Barbara Rolls. They found that when people ate a first course of soup before lunch they reduced their total calorie intake by 20 per cent, compared with those who did not begin the meal with soup. But those who _ creamy soups should be careful.Researchers stressed the soup must be low-calorie and based on stock , not cream. All of the soups tested in the study were made from identical ingredients - chicken stock , broccoli , potato, cauliflower and carrots. They were mixed together to create four different textures and thickness from separate stock and vegetables through to pureed soup. Scientists thought that thick soups with chunks of vegetables which required chewing might be more filling, but to their surprise they found all forms had the same effect. The findings were presented to the Experimental Biology conference in Washington, DC, and the research was part-funded by the National Institutes of Health. What's the reason that adding low-calorie vegetable soup to the start of a meal can actually help to lose weight? | [

mmlu_train_36350 | For anyone still doubting the belief that our emotions impact our physical health, a new study from New Zealand should be able to settle the matter. It reports that the physical wounds of healthy seniors healed more quickly if they wrote about their most upsetting experiences. This confirms the results of a 2010 study, and extends those findings to cover older adults-a group that is likely to suffer wounds (as from surgery), and one with less access to other ways of lowering tension (such as exercise). Reported in the journal Psychosomatic Medicine, a research team led by the University of Auckland's Elizabeth Broadbent made a study featuring 50 healthy adults ranging in age from 64 to 97. They were assigned to write for 20 minutes per day for three consecutive days. Half were asked to write about the most upsetting experience in their life, describing their deepest thoughts, feelings, and emotions about the events, ideally not previously shared with others. The others were asked to write about their daily activities without mentioning emotions, opinions or beliefs. Two weeks after the third day of writing, all participants received a standard 4mm skin biopsy on their inner arm. The very tiny wounds caused by the biopsy were photographed regularly over the following days to determine the rate at which they healed. On the 11th day after the biopsy, the wounds completely healed on 76.2 percent of those who had done the expressive writing. That was true of only 42.1 percent of those who had written about everyday activities. "The biological and psychological mechanisms behind this effect remain unclear," the researchers wrote, noting that those who had done the expressive writing did not report lower stress levels or fewer depressive symptoms than the others in the control group. Even if they weren't consciously aware of feeling more relaxed or positive, the expressive writing appeared to have caused some sort of bodily reaction-probably involving their immune systems-that hastened their recovery.

mmlu_train_10988 | Skateboarding has become one of several non - traditional activities that PE teachers around America are introducing to inspire kids to exercise regularly. Some PE classes feature in-line skating, yoga, and even rock climbing. Experts have called those types of activities "the new PE". Such activities are part of a larger effort to help kids develop lifelong fitness habits and to keep them from becoming overweight. Now, 9 million U.S. children and teens are overweight. Obesity can lead to health problems such as diabetes and heart disease later in life. "Our children and youth are becoming unhealthy and obese," says Lindsey Johnson. "Skateboarding is a great activity that keeps kids doing physical movement and gives them new skills and interest." Some schools don't allow skateboarding because they say it is dangerous. Cendali, however, argues that regular practice _ a great deal of the danger. "We teach students how to do it and how to do it safely," he says. Some people say skateboarding teaches life lessons. "Skateboarding teaches kids to believe that if they stick with something they will finally succeed," says education expert Richard Sagor of Lewis & Clark College in Portland, Oregon. Skateboarding inspires kids not to give up in learning difficult skills. "It's natural for kids to want to learn and get better at things," adds Sagor. "When it comes to skateboarding, they'll try a trick hundreds of times before they succeed." That same effort could be made in schoolwork. Eric Klassen agrees that skateboarding requires kids to stop saying a task is too hard for them. "A baby will attempt to walk 600 to 900 times before he or she is successful," says Klassen. "We tell students that they shouldn't say 'I can't do it' unless they've tried 600 to 900 times." Skateboarding is introduced into American schools to _ . | [

mmlu_train_50054 | If I see one more article about how wonderful alternative energy is compared to oil, I will flip . Alternative energy sources can be good---- very good in fact. And it's pretty obvious that we're going to need them, and that our dependence on oil is a Bad Thing. But accepting that does not mean accepting that any kind of alternative energy is a good thing. To be a good thing, it has to have three properties: 1) It has to help reduce our dependence on oil, 2) It has to be no worse for the environment, and 3) It has to be economically practical. Many of the things praised meet one or even two of those properties. Solar panels, for example. They can reduce our need for oil, at least in certain regions, and they're certainly not bad for the environment. But they're expensive. If you spend the money to make your home solar-powered, you probably won't get back your costs for at least 15 years, which approaches the lifespan of the panels. Certainly we need to clean up our act big time and find workable sources of alternative energy. But we also have to keep in mind that every one of these alternative-energy sources comes at a cost, which is something people seem to forget. They hear the phrase "alternative energy" and automatically assume it's got to be good. But green isn't always good, and oil isn't always bad. One seemingly "green" technology that pops up again and again is electric cars. It is praised by well-meaning people as good for the environment and a way to reduce our oil dependence, especially as oil prices continue to rise. Electric cars are dirty. In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins. People in California love to talk about " zero-emissions vehicles", but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something---- usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal plants as well, but by far we get electricity mainly by burning something. In other words, those "zero-emissions" cars are likely coal-burning cars. It's just because the coal is burned somewhere else that it looks clean. It is not. It's as if the California Greens are covering their eyes ---- " If I can't see it, it's not happening. " Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas ( or another fue) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat ---- at the generator, through the transmission lines, etc. A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far ---- so electric cars burn more fuel than gas- powered ones. If our electricity came mostly from nukes; or geothermal, or hydro, or solar, or wind, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources. In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill. And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one lace. Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.

mmlu_train_50548 | Over the centuries the French have lost a number of famous battles with the British. However, they've always felt superior in the kitchen. France has for centuries had a reputation for cooking excellence, and Britain for some of the worst cooking in the world. But according to a recent survey, _ In the survey, 71% of the Britons said they cook at home every day, while only 59% of the French said they cook daily. British home cooks spend more time cooking each week and also produce a greater variety of dishes than French home cooks. The reaction in London was predictably enthusiastic. British food has greatly improved since the 1990s. Once upon a time, the menu for many family meals would have been roast beef, potatoes and over-cooked vegetables, but not now. Home cooks are experimenting with the huge range of ingredients now available in British supermarkets and are preparing all kinds of new dishes, using the cookbooks that sell millions of copies every year. As a result, there's much more diversity in British food now, compared to French food, which tends to be very traditional. Some French people say that the survey did not show the whole picture. They agree that during the week French women don't cook as much as they used to because most of them work and don't have much time. They tend to buy ready-made or frozen dishes, but many of them make up for it on the weekend. There's also a difference between Paris and the country-side. It's true that people in Paris don't cook much, but elsewhere, cooking is still at the heart of daily life. For many French people, opinions about British food have not changed. When Bernard Blier, the food editor at a magazine, was asked about British food, he replied: "I don't go out of my way to try it. It is not very refined. You can say that I'm not a fan at all."

mmlu_train_62018 | If you see someone drowning, speed is very important. Once you get him out of the water, if he isn't breathing, you have four minutes before his brain is completely destroyed. Support his neck, move his head back and press his chin upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn't work, start mouth-to-mouth breathing. Press his nostrils (the two holes at the end of your nose, through which you breathe and smell things) together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until professional help arrives. To bring a child back to life, keep your lips around his mouth and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue-grey colour, and you can feel no pulse , then pressing is the last chance of saving his life. With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don't be too hard or you may break a rib.

mmlu_train_46871 | LONDON (Reuters)--New faces given to a Chinese man after a bear tore off part of his face and a FrenchCaribbean man disfigured by a rare tumor show that such transplants can work and are not medical oddities ,researchers said. The findings give hope to some people with severe facial disfigurement and suggest the transplants could prove longlasting without major problems.Despite the tissue rejection in the first year after their transplants,neither men had psychological problems accepting their new faces and have been able to rejoin society,they reported. Only three people have received face transplants.The world's first was carried out on French woman Isabelle Dinoire in November 2005 after she was disfigured in an attack by her dog.In 2007,her doctors reported that she had recovered slowly and steadily,overcoming two periods of rejection. In 2006,Chinese doctors performed a face transplant on a 30yearold hit by a bear.While there were some complications with tissue rejection following the operation,two years later the man was doing well,his doctors said."This case suggests that facial transplantation might be an option for _ a severely disfigured face,and could enable patients to bring themselves back into society," Shuzhong Guo and colleagues at Xijing Hospital in China wrote. A French team described their work on a 29yearold man who suffered from Von Recklinghausen disease,an illness that changes the shape of his face."The man,who was not named,was given a new nose,mouth and chin in a 2007 operation.He began to work 13 months after the transplant has more function in his face and has not rejected the new tissue," his doctors said.

mmlu_train_15081 | Reducing the amount of sleep students get at night has a direct impact on their performance at school during the day. According to classroom teachers, elementary and middle school students who stay up late exhibit more learning and attention problems. This has been shown by Brown Medical School and prefix = st1 /BradleyHospitalresearch. In the study, teachers were not told the amount of sleep students received when completing weekly performance reports, yet they rated the students who had received eight hours or less as having the most trouble recalling all the material, learning new lessons and completing high - quality work. Teachers also reported that these students had more difficulty paying attention. The experiment is the first to ask teachers to report on the effects of sleep deficiency in children. Just staying up late can cause increased academic difficulty and attention problems for otherwise healthy, well - functioning kids, said Garharn Forlone, the study's lead author. So the results provide professionals and parents with a clear message: when a child is having learning and attention problems, the issue of sleep has to be taken into consideration. "If we don't ask about sleep, and try to improve sleep patterns in kids' struggling academically, then we aren't doing our job", Forlone said. For parents, he said, the message is simple, "getting kids to bed on time is as important as getting them to school on time." What were teachers told to do in the experiment? | [

mmlu_train_42061 | When a caterpillar feeds on a tomato leaf , the plant moves rapidly to meet with a defensive response , systematically releasing " proteinase inhibitors " -- proteins that interfere with the caterpillar's digestion -- throughout the plant , especially in the leaves . But how does the message get from the wounded leaf to the rest of the plant ? Most scientists believed the alarm was spread by chemical messengers until a team of researchers headed by David Weldon-- a biologist at the University of East Anglia in Norwich , England -- made a shocking discovery . An injured leaf , the researchers found , sends an electrical signal to warn neighboring leaves of upcoming danger . It's a " terribly tiny current " driven by an electrical potential difference of only 20 millvolts , says Weldon , who measured the voltage after electrodes were attached to the plant's surface . " Right now , all we can say is that there is a correlation , " Weldon notes . " If you wound the plant , you'll see an electrical signal accompanied by a biochemical response . " To learn more about the reaction , Weldon's team plans to insert electrodes within the pant tissue ( rather than on the surface ) to determine what's going on at the cellular level . The findings may help explain other mysteries surrounding plants . For example , many plants start to flower in springtime , as days grow longer , but plants sense the change in the day length through their leaves , while flowers begin to bloom at the buds . " There must be a signal from the leaf to the growing points , " Weldon says . " So far , no one has come up with a convincing chemical mechanism . Maybe an electrical signal is involved .

mmlu_train_61987 | Our world is a noisy place, but quiet places remain. Eight years ago, audio engineer Gordon Hempton identified the quietest place in the continental United States. He calls the place "One Square Inch of Silence." He has used his symbolic spot in a northwestern rain forest to campaign against noise pollution. But the self-described "Sound Tracker" is now going deaf. For Gordon Hempton, it started with an experience known to many people. "I was lying in the bed in the springtime about a year ago. The sun was shining. The birds could be singing. They should be singing. But I was hearing none. I knew my life was going to be different." Hempton's eyes get watery as he describes his cruel situation. More than 20 years ago he trademarked his nickname as "The Sound Tracker." Sharp hearing defined his career as an Emmy award winning sound recordist. It also led to his activism against noise pollution. He has circled the globe three times in search of the perfect sounds of nature. Hempton says his hearing loss is quickly getting worse but he has to finish his project. "I am running a race to finish the Quiet Planet collection." That's the title of a planned 19-volume set of nature recordings. The sound tracks could be licensed for use in movies, video games, exhibits, plays and the like. Volunteer assistants now help Hempton review and edit sound files and identify imperfections.

mmlu_train_54059 | The next generation of smart phone could combine the date from its gyroscopes with a built-in compass to allow you to track your indoor movements even without GPS. Research described it in the international Journal of Innovative Computing and Applications by Shahid Ayub of Lancaster University, and his colleagues there and at HW Communications, suggests that the embedded inertial sensors in many smart phones have added the facility to be used for localization and tracking applications. The primary benefit of using smart phones is that no additional infrastructure would need to be installed for monitoring personnel movements in a wide variety of situations not least staff, equipment and inventory movements in warehouse facilities, shopping malls and factories. In contrast, other technology being proposed would require new equipment,such as RFID technologies. However, smart phones do not yet have the ability to pinpoint their location without recourse to the GPS system, which is not accessible indoors and has the added disadvantage of using up battery power very quickly even if it could be used. Inertial navigation only provides the necessary information to a specified starting point the team says. This is useful for anyone with a non-GPS smart phone who wishes to track the route they take when walking or jogging if they specify their starting point. The team suggests that pedestrians indoors could be positioned using a combination of the smart phone accelerometer and an built-in digital compass, something that will become available in future smart phones. They have now investigated the potential of three different smart phone placement modes: idle, hand held and listening, which could be used with pedestrian dead reckoning (PDR) techniques to allow users to record the path they follow or for various kinds of workplace or other monitoring requirements. "The technique could be used in underground tube stations, airports , train stations where there is no infrastructure installed for tracking or navigation," Ayub explains, "It can also be used for location-based service applications. In big shopping malls it becomes easier to navigate to a target shop or meeting place, while in large offices and across industry it could be used to track employees and control movements of workers in restricted areas." We can learn from the passage that the recent studies of smart phones _ . | [

mmlu_train_60939 | I have been consistently opposed to feeding a baby regularly. As a doctor, mother and scientist in child development, I believe there is nothing to recommend it, from the baby's point of view. Mothers, doctors and nurse alike have no idea of where a baby's blood sugar level lies. All we know is that a low level is harmful to brain development and makes a baby easily annoyed. In this state, the baby is difficult to calm down and sleep is impossible. The baby asks for attention by crying and searching for food with its mouth. It is not just unkind but also dangerous to say a four-hourly feeding schedule will make a baby satisfied. The first of the experts to advocate a strict clock-watching schedule was Dr Frederic Truby King who was against feeding in the night. I've never heard anything so ridiculous. Baby feeding shouldn't follow a timetable set by the mum. What is important is feeding a baby in the best way, though it may cause some inconvenience in the first few weeks. Well, at last we have _ research that supports demand feeding and points out the weaknesses of strictly timed feeding. The research finds out that babies who are fed on demand do better at school at age 5, 7, 11 and 14, than babies fed according to the clock. By the age of 8, their IQ scores are four to five percent higher than babies fed by a rigid timetable. This research comes from Oxford and Essex University using a sample of 10,419 children born in the early 1990s, taking account of parental education, family income, a child's sex and age, the mother's health and feeding style. These results don't surprise me. Feeding according to schedule runs the risk of harming the rapidly growing brain by taking no account of sinking blood sugar levels. I hope this research will put an end to advocating strictly timed baby feeding practices. What does the author think about Dr King? | [

mmlu_train_8477 | Why can some people sleep through noises like a honking car or flushing toilet, while others are awakened by the lightest sound? To find the answer, sleep researchers at Massachusetts General Hospital conducted an unusual study of 12 self-described deep sleepers. After tests confirmed that the healthy volunteers were solid sleepers, they took part in a three-night study in the university's sleep laboratory. The participants spent the night in a big and comfortable room. But the room also included four speakers positioned near the top of the bed. During the night, the deep sleepers were subjected to 14 different recorded sounds, like street traffic, toilets flushing, an ice machine dispensing and an airplane flying overhead. Next door, the researchers monitored their sleep patterns and brain waves. As expected, all of the participants slept ly well, but there were differences in how they responded to the noisy interruptions. Some of the sleepers didn't wake up even when a sound was blasted at 70 decibels ; others were awakened by sounds at 40 or 50 decibels. The researchers discovered that the difference in a sleeper's reaction to noise could be predicted by the level of brain activity called "sleep spindles''. A sleep spindle is a burst of high-frequency brain activity coming from deep inside the brain during sleep. The source of the spindles is the thalamus, a part of the brain that sends sensory information to the rest of the cortex . Before the study, the Massachusetts researchers theorized that the spindles are the brain's way of preventing sensory information from passing through the thalamus and waking the rest of the brain during sleep. They found that the sleepers who experienced the most sleep spindles during the night were also the soundest sleepers and were least likely to be awakened by noise. Scientists already know that most people become lighter sleepers with age, most likely because older people experience less "slow wave sleep'', which is the deepest stage of sleep. People also produce fewer sleep spindles as they age. But even when controlling for the stage of sleep a person was in, the number of sleep spindles still predicted their risk for awakening because of noise. More research is needed, but the findings suggest that a better understanding of sleep spindles could lead to new behavioral or drug therapies for people with sleep disorders. For instance, future studies may try to determine whether diet, exercise or other behaviors may influence the number of sleep spindles a person produces during the night. Some participants can sleep well through loud noises mainly because _ . | [

mmlu_train_21624 | John von Neumann was the oldest of 3 children of an banker, and his speed of learning new ideas and solving problems stood out early. 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. Von Neumann really was a legend in his own time, and there are a number of stories about him. His driving ability is a part of his legend.

mmlu_train_20860 | Dear Customers, I love slipping into a comfortable chair for a long read--as I relax into the chair, I also relax into the author's words, stories and ideas. The physical book is so elegant that it disappears into the background, and what remains is the author's world. Today, we at Amazon are excited to announce Mindle, a wireless, portable reading device with instant access to more than 90,000 books, magazines and newspapers. We've been working on Mindle for more than three years. Our top design objective was for Mindle to disappear in your hands--to get out of the way--so you can enjoy your reading. We also wanted to go beyond the physical book. Mindle is wireless, so whether you're lying in bed or riding a train, you can think of a book, and have it in less than 60 seconds. No computer is needed--you do your reading directly from the device. We chose the same wireless technology used in advanced mobile phones. But unlike mobile phones, there are no monthly wireless bills, no service or data plans, and no yearly contracts. There is no software to install (,). We want you to get lost in your reading and not in the technology. Mindle uses a new kind of display called electronic paper. Sharp and natural with no strong light, reading on Mindle is nothing like reading from a computer screen. Mindle weighs only 10.3 ounces--less than paperback--but can carry two hundred books. Enjoy learning about Mindle and many thanks! Jeff Bezos Founder & CEO From the passage we learn that Mindle is a device which _ . | [

mmlu_train_70088 | In the Caucasus region , nearly 50 out of every 100,000 people live to celebrate their 100thbirthday, and many don't stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Caucasus people aren't alone. The Pakistani Hunzas, who live high in the Himalaya Mountains, and the Vilcabambans of the Andes Mountains in Ecuador seem to share the secret of long life too. These peoples remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasus people aged 110-140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked, "At what age does youth end?" most of these old people had no answer. Several replied, "Well, perhaps at age 80." The very youngest estimate was age 60. What accounts for this ability to survive (live) to such old age, and to survive so well? First of all, hard physical work is a way of life for all of these long-lived peoples. They began their long days of physical labor as children and never seem to stop. For example, Mr. Rustam is 142 years of age. He remembers his life experience: the Crimean War of 1854; the Turkish War of 1878; the Bolshevik Revolution in 1917. His wife is 116 years old. They have been married for 90 years. Mr. Rustam has no plan of retiring from his life as a farmer. "Why? What else would I do?" he asks. Oh, he's slowed down a bit. Now he might quit (stop working) for the day after 6 hours in the field instead of 10. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 5,000 to 12, 000 feet(1,660 to 4,000meters) above sea level. The air has less oxygen and is pollution-free. This reduced oxygen environment makes the heart and blood vessel system stronger. Another factor that may lead to the good health of these people is their isolation. To a great extent, they are separated from the pressure and worries of industrial society. Inherited factors also play some role. Most of the longest-lived peoples had parents and grandparents who also reached very old age. Good family genes may, therefore, be one factor in living longer. Finally, although these three groups don't eat exactly the same foods, their diets are similar. All of them eat little animal meat. Their diets are full of fresh fruits, vegetables, nuts, grains, cheese and milk. They never eat more food than their bodies need. It is clear that isolation from urban pressure and pollution, clean mountain air, daily hard work, moderate diets, good genes, and a youthful approach to life all lead to the health and remarkable long life of all these people. How do you think the writer feels about these long-lived people? | [

mmlu_train_47591 | More than two million Americans above 65 years of age suffer from depression. And in the next 35 years, twice as many people will find themselves in that age range --including me, and probably you too! So, what activities can prevent depression as we get older? Researchers at UCLA turned to a gentle "Westernized" version of tai chi, the 2,000-year-old Chinese martial art . When a group of adults over 60 on antidepressant drug therapy attended a weekly tai chi exercise class, standard rating scales showed greater improvement in their level of depression, along with improved quality of life, better memory and cognition , and more overall energy when compared to study participants taking the same medicine but going to a weekly health education class. "This is the first study to prove the benefits of tai chi in the management of late-life depression, and we were encouraged by the results," said Dr Helen Lavretsky, a UCLA professor. "We know that nearly two-thirds of elderly patients who seek treatment for their depression fail to achieve relief with a prescribed medication ." In the study, 112 adults above 60 with major depression were treated with the prescription antidepressant medicine for approximately four weeks.Among those participants, 73 who showed only little improvement continued to receive the daily medication but were also assigned to 10 weeks of either a tai chi class or a health education class for two hours per week. "Both groups showed improvement in the severity of depression," said Lavretsky. But greater benefits were noted among those participating in tai chi. This study shows that adding a mind-body exercise like tai chi, which is widely available in the community, can improve the outcomes of treating depression in older adults.With tai.chi, we may be able to treat other, coexisting medical conditions without exposing them to additional medications."

mmlu_train_10671 | The rise in smartphones among young people may be having a direct effect on how successful they become as adults. Research from the University of Nebraska-Lincoln has discovered the average university student checks their phones 11 times per lesson, and more than 80 percent believe this tech addiction is interfering with their learning. A quarter of students across five U.S states also blamed poor grades in exams specifically on the fact they used mobile devices when they should have been concentrating and revising - and these grades could determine the jobs they end up going into. Barney McCoy, an associate professor of broadcasting at the university, surveyed 777 students at six universities across five states about how they used digital devices in the classroom. The students were from UNL and the University of Nebraska at Omaha in Nebraska, Morningside College in Iowa, the University of North Carolina, the University of Kansas and the University of Mississippi. Around two thirds said they used phones, tablets and laptops for "non-classroom purposes" up to ten times during a typical university day, while 15 percent admitted this figure was closer to 30 times. Among the top reasons why students checked their devices so regularly were staying connected and fighting boredom, at 55 percent. Less than half said the devices were used for classwork. Texting was the most popular distraction technique at 86 percent, while 68 percent said they used their phones to check personal emails. Two thirds used social networks, 38 percent surfed the web and eight percent admitted to playing games when they should have been studying. Despite eight out of ten students admitting their devices were distracting, fewer than five percent considered it to be a "very big" distraction. "I don't think students necessarily think it's a big problem," said McCoy said. "They think it's part of their lives." "It's become automatic behavior on the part of so many people - they do it without even thinking about it." He continued, "They've got their laptops open, but they're not always taking notes. Some might have two screens open -- Facebook and their notes." _ was the most popular form of distraction. | [

mmlu_train_30944 | Could smells affect your lifespan? Female fruit flies rid of the ability to smell food outlive their peers.The sense of smell may be linked to the cellular ageing process in many other organisms--even people.A link has recently been found between sensory experiences and lifespan in both worms and flies.For example, Scott Pletcher, a biologist at the University of Michigan, found that eliminating fruit flies' ability to smell enabled them to live nearly 20 percent longer than flies with an intact sense of smell. Pletcher's team reasoned that food smells were the ones most likely to affect ageing, as nutrition and longevity are known to be linked in many organisms.To test the idea that food odors affect lifespan, Pletcher's team eliminated flies' ability to smell carbon dioxide, which is produced by some fly foods.They left the rest of the smelling system intact. This intervention had no effect on male flies, but the females lived 30 percent longer than normal.Pletcher thinks eliminating the ability to smell CO2may deprive flies of information about food availability.This could signal to cells that food is scarce, causing processes that promote survival.Indeed, his team found that the CO2-insensitive female flies stored extra fat and that both males and females immune to CO2were more resistant to stress than normal flies.Pletcher isn't sure why the change in his fruit flies only affected the lifespan of the females, but he suggests that females may simply be more sensitive to the odor of CO2. A smell or taste that stretches lifespan in humans could be a potential preventative for age-related disease, he adds.Although in fruit flies it appears to be the smell of CO2that affects ageing, he says that an analogue in humans might be a smell or taste linked to human food--or a lack of it.Matt Kaeberlein studies ageing at the University of Washington in Seattle. He cautions that we don't know whether ageing and smell are linked in mammals.But " we definitely undergo physiological changes in response to smelling food--I'm getting hungry just thinking about it--so I think it's possible." The purpose of the study by Scott Pletcher is to _ . | [

mmlu_train_64714 | Imagine life without the Internet -- not being able to chat with your friends or look up information for your homework or research project. That is the reality for nearly two-thirds of our world's population, either because they cannot afford WiFi access or are located in remote, inaccessible areas. Now Google has decided to do something about that. Google's Project Loon will attempt to send balloons high up into our earth's atmosphere in 2015. Each balloon will be equipped with a mini computer and a WiFi radio that will send Internet signals over the places it is floating over. The network equipment on Google balloons will communicate with a special antenna attached to each user's home. These antennae are in turn connected to a local Internet Service Provider. Each balloon will also communicate with each other to hand over signals as one floats out of an area, and another floats in. The balloons are 15 meters wide and made of a material that is three times thicker than the plastic bag at the supermarket. This helps them defend themselves against cold temperatures and changing air pressure. Google balloons will circle the earth at a height of 20 kilometers-- in a layer of our atmosphere known as the stratosphere . This is higher than the altitude at which planes fly. Once the balloons reach the desired altitude after being released from the earth, they will ride on air currents. What keeps these balloons from flying away? They will be controlled by people at the Project Loon command center. A pump operating on solar power will fill the balloon with gas to raise it or let gas out to lower it, based on instructions. This allows the balloon to float on different air currents which are moving either clockwise or anti-clockwise. There is no doubt that this technology can bring education to many children, weather information to farmers, and communication to natural disaster areas. However, one big question remains -- will some countries be comfortable with balloons above their heads? There could be concerns about spying and other problems.

mmlu_train_6547 | Cooking food over a smoky fire is found everywhere in the world. It is often difficult to find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun. Solar cookers, or ovens, have been used for centuries. A Swiss scientist made the first solar oven in 1767. Today, people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms. There are three kinds of solar ovens. The first is a box cooker. It is designed with a special wall that shines or reflects sunlight into the box. Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amounts of food. The second kind of solar oven is a panel cooker. It includes several flat walls, or panels, which directly reflect the sun's light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya, for example, panel cookers are being manufactured for just two dollars. The third kind of solar oven is a parabolic cooker. It has rounded walls that aim sunlight directly into the bottom of the oven. Food cooks quickly in parabolic ovens. However, these cookers are hard to make. They must be re-aimed often to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly. You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at 232 degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things. To learn more about solar cooking, you can write to Solar Cookers International. The postal address is nineteen-nineteen Twenty-First Street, Sacramento, California, nine-five-eight-one-one, USA. Or you can visit the group's Internet Web site. The address is www.solarcooking.org. Which of the following is TRUE? | [

mmlu_train_61154 | It is often assumed that people with parents who lived to be very old are more likely to live to a grand old age themselves. "But that's just not true - our study shows that hereditary factors don't play a major role and that lifestyle has the biggest impact." says professor Lars Wilhelmsen, referring to the 1913 Men Study that formed the basis of the current research. Those who did not smoke, consumed mild amounts of coffee and had a good socio-economic status at the age of 50 (measured in terms of housing costs), as well as good physical working ability at the age of 54 and low cholesterol at 50 had the greatest chance of celebrating their 90th birthday. "We're breaking new ground here." says Wilhelmsen. "Many of these factors have previously been identified as playing a role in cardiovascular( )disease, but here we are showing for the first time that they are important for survival in general," He believes that it is significant that the research illustrates so clearly that it is the sum of our own habits that has the biggest impact. "The study clearly shows that we can influence several of the factors that decide how old we get," says Wilhelmsen. "This is positive not only for the individual, but also for society as it doesn't need any major drug costs," The study has been published in the Journal of Internal Medicine. The 1913 Men study started up in 1963. A third of all male 50-year-olds in Gothenburg were called for a check-up that focused on cardiovascular health. Every ten years since, a new group of 50-year-olds has been called in and those who were already taking part in the study have been given another check-up. This has enabled researchers to follow the development of illnesses in a specific age group, and to compare the health of 50-year-olds in 2003 with that of 50-year-olds in 1963, for example. Women have also been included in the study since 2003. Data have been studied over the years. including BMI , smoking habits, cholesterol, exercise habits and blood pressure, The men born in l913 were examined when they were 50, 54,60, 67, 75 and 80. Of the 855 men who took part in the study from the start, lll (13%) were still alive at the age of 90. Over the years the material has brought out many research articles. An interesting result came in 2008 when researchers were able to show that the drop in the number of smokers, combined with lower cholesterol levels and lower blood pressure, between 1963 and 2003 could offer an explanation for the marked downturn in the number of heart attacks during this 40-year period. The earlier men involved in the 1913 Men Study were examined in _ for the second time. | [

mmlu_train_49864 | October 15th2008 is the first Global Handwashing Day, whose goal is to create a culture of hand washing with soap. Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap. 150,000 bars of soap were given to schools in prefix = st1 /Ethiopia, where the Education Ministry asked 1,000,000 schoolchildren to wash their hands for _ . Experts say people around the world wash their hands but very few use soap at critical moments such as after using the toilet, after cleaning a baby and before touching food. The organizers say all soaps are equally effective at removing disease-causing germs . They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least 20 seconds. Then, wash your hands well under running water. Finally, dry your hands with a clean cloth or wave them in the air. They say soap is important because it increases the time that people spend washing. Soap also helps to break up the grease and dirt that hold most of the germs. And it usually leaves a pleasant smell, which encourages people to wash again. They say washing with soap before eating and after using the toilet could save more lives than any vaccine or medicine. It could help reduce cases of diarrhea by almost half. And it could reduce deaths from pneumonia and other breathing infections by one-fourth. Diarrhea is the second leading cause of child deaths, killing more than 1,500,000 children a year. Pneumonia is the leading cause, killing about 2,000,000 children under five each year. Hand washing can also prevent the spread of other diseases. When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.

mmlu_train_25635 | If you look outside, you probably will see some kind of insect. If your first instinct is to kill it, take a moment to think about all of the benefits insects provide to the environment. Entomologists, scientists who study insects, estimate that there are more than 800,000 species of insects found throughout the world. Only a few hundred of these insects are considered harmful. Mosquitoes, for example, are considered harmful. They bite humans and other animals, and their bites can cause skin pain and spread disease. Desert locusts also are considered harmful because they destroy crops causing billions of dollars in damage each year. However, the number of helpful insect species far outweighs the number of harmful species. Some insects make up a vital part of the food chain. Many different birds, reptiles, fish and even plants eat insects. There are also about 500 insects that people in various parts of the world eat. These insects are considered delicious food and prized for their high protein, mineral, and vitamin content. Other insects produce valuable commercial products such as silk, wax, and honey. Of all the insects, perhaps the most important are those that travel from flower to flower and pollinate the plants they visit. Agriculture around the world would be very different without the bees, butterflies, moths, flies and wasps that pollinate many crops. In fact, nearly one-third of the food you eat depends on plants that are pollinated by insects! While it is true that some species of insects harm or annoy us, _ .

mmlu_train_37668 | Raising a baby takes a lot of work, especially when that baby is a king penguin. Now, it looks like climate change will make life even harder for these birds. A new study suggests that warmer waters could make their numbers _ Most king penguins live on the Crozet Archipelago, a group of islands in the Indian Ocean, about 1,000 miles north of Antarctica. After the penguin chicks are born in November (which is summer in the Southern Hemisphere), both parents spend 4 months collecting fish to feed their children. When the fish move to deeper waters in March, the adults leave their chicks alone for months. They swim hundreds of miles south. There, near the Antarctic ice, they spend the winter eating seafood, such as squid, to add their own energy stores. In October, nearly a year after their chicks are born, the parents return to feed and finish raising them. Scientists from the French National Center for Scientific Research (CNRS) in prefix = st1 /Strasbourg,France, have been studying king penguins on the Crozet Archipelago for a decade. Starting in 1998, Yvon Le Maho and other researchers implanted electronic ID tags under the skin of hundreds of penguins. The tags have allowed Le Maho's team to know the details about them, such as how long they live, whether they return from their winter trips, and if their chicks manage to survive the winter. Ocean surface temperatures vary from year to year. And former research had shown that fewer squid, fish and other creatures grow when the water is warmer. Le Maho suspected that this drop in the food supply would make it harder for adult penguins to survive the tough times ahead. King penguins can live for up to 30 years. And for now, the population still appears healthy. But a warming trend could cause big trouble for a bird that depends on cold and ice. What's the main idea of this passage? | [
