mmlu_train_24309 | My house is made of wood, glass and stone. It is also made of software. If you come to visit, you'll probably be surprised when you come in: Someone will give you an electronic PIN to wear. The PIN tells the house who you are and where you are. The house uses this information to give you what you need. When it's dark outside, the PIN turns on the lights near you, and then turns them off as you walk away from them. Music moves with you, too. If the house knows your favorite music, it plays it for you. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings. Of course, you are also able to want something. There is a home control console which is a small machine that turns things on and off around you. The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you the key to my car, you can use my car. The car works for you because you have the key. My house works for you because you wear the PIN or hold the console. I believe that in ten years from now, most new houses will have the systems that I've put in my house. The systems will probably be even bigger and better than the ones I've got. I like to try new ideas. I know that some of my ideas will work better than others'.

mmlu_train_16445 | Sharks have lived in the oceans for over 450 million years, long before dinosaurs appeared. There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely. Every year, we catch and kill over 100 million sharks, mostly for food and for their fins. Dried shark fins are used to make shark fin soup, which sells for as much as $50 a bowl in fine Hong Kong restaurants. Other sharks are killed for sport and out of fear. Sharks are vulnerable to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring . Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of shark injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea lions and other marine mammals. They sometimes mistake human swimmers for their normal prey, especially if they are wearing black wet suits. If you are a typical ocean-goer, your chances of being killed by an unprovoked attack by a shark are about 1 in 100 million. You are more likely to be killed by a pig than a shark and thousands of times more likely to get killed when you drive a car. Sharks help save human lives. In addition to providing people with food, they are helping us learn how to fight cancer, bacteria, and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system allows wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research. Sharks are among the few animals in the world that almost never get cancer and eye cataracts . Understanding why can help us improve human health. Chemicals taken from shark cartilage have killed cancerous tumors in laboratory animals, research that someday could help _ your life. Sharks are needed in the world's ocean ecosystems. Although they don't need us, we need them. We are much more dangerous to sharks than they are to us. For every shark that bites a person, we kill one million sharks.

mmlu_train_61683 | Rae and Bruce Hostetler not only work very hard,they also relax just as well. Numerous vacations help the couple to maintain their health and emotional well-being-and it's no surprise to health care professionals. "Rest,relaxation, and stress reduction are very important for people's weLl-being and health. This can be accomplished through daily activities,such as exercise and meditation,but vacation is an important part of this as well," said primary care physician Natasha Withers from One Medical Group in New York. Withers lists a decreased risk of heart disease and improved reaction time as some of the benefits from taking some time off. "We also know that the mind is very powerful and can help with healing,so a rested,relaxed mind is able to help the body heal better," said Withers. Psychologists confirm the value of vacations for the mind. " The impact that taking a vacation has on one's mental health is great," said Francine Lederer,a clinical psychologist in Los Angeles who specializes in stress and relationship management. " Most people have better life perspective and are more motivated to achieve their goals after a vacation,even if it is a 24- hour time-out. " The trips could be good for their health,good for their family and good for their .businesses. The online travel agency Expedia conducted a survey about vacation time in 2010,and according to their data the average American eamed 18 vacation days-but only used 14 0f them. France topped the list,with the average worker earning 37 vacation days and using all but two of them. Americans' responses may not be surprising in a culture where long hours on the job often are valued,but that's not always good for the individual,the family or the employer. Psychologists have also found that people who don't take enough time to relax may find it harder to relax in the future. "Without time and opportunity to do this,the nerve connections that produce feelings of calm and peacefulness become weaker,making it actually more difficult to shift into less-stressed states," Mulhern said.

mmlu_train_63773 | Airtight plastic bags can help farmers protect their harvests without the use of harmful chemicals. These bags are designed to keep air out of crops in storage. Using them is a simple way to fight insects and keep crops fresh. Ten countries in West and Central Africa are involved in a project to improve the storage of cowpeas, also known as black-eyed peas. Farmers can lose much of the harvest to insects called bruchids , which grow from egg to adult in a few weeks and then lay forty to sixty eggs. They can destroy the whole harvest within months. Farmers can sell their crops immediately. But selling at harvest time means more competition and lower prices.Or they can use pesticides to kill the bugs. But a crop scientist Dieudonne Baributsa says, "They end up misusing or overusing the pesticide. In Nigeria, they have reported a lot of cases of death. They usually call cowpeas 'killer beans' in Nigeria." Mr. Baributsa is a researcher at Purdue University in Indiana, America. The project is called PICS---Purdue Improved Cowpea Storage. He says the storage bags are thick enough that any insects already in the cowpeas willdie from a lack of oxygen. The lack of air will also help prevent the growth of bacteria that can ruin the harvest. The bags cost about two dollars each. Mr. Baributsa says that is not much, especially if it means farmers can wait long enough to get a better price for their crops. The bags are produced locally. Donors currently support the project, but the groups involved are working to build a lasting market for the bags because donation for the project will not lastforever. A company based in the United States called GrainPro makes another kind of airtight bags. These are called SuperGrainbags. Phil Villers, the company's president, says storing a harvest safely not only helps farmers earn more money, but also reduces the amount of the harvest loss to insects, spoilage and mishandling. "What does not get wasted and eaten means it is possible to feed a hungry world," said Phil Villers. What is the best title for this passage? | [

mmlu_train_32944 | Women should not drink any alcohol during pregnancy. A report released by NICE says. It says if they must drink, they should not do so in the first three months and should limit to one or two ounces once or twice a week afterwards. It replaces previous guidance of saying small daily amounts were fine. NICE decided to tighten its guidance partly because of the concern that people are now drinking more than in the past. Previous draft guidance suggested women should drink an ounce of alcohol a day once they were past the first three months of pregnancy. The Department of Health in England changed its guidance last year, calling for no drinking while pregnant or while trying to get pregnant. Drinking heavily in pregnancy can cause fetal alcohol syndrome , which can leave children with features like small heads, widely spaced eyes and behavior or learning problems. The experts said there was no evidence that several ounces once or twice a week would do any harm to the baby but could not categorically rule out any risk. National Childbirth Trust agreed women should limit their drinking during pregnancy. "Pregnant women who have had a few drinks often worry a great deal about whether they have harmed their baby. In general, it is believed that if a light infrequent drinker, in good health, drinks to the point of drunkenness on one occasion, the risk to her baby is small." NICE also made a number of other recommendations for the care of women in the UK who were pregnant or planning to get pregnant. It said vitamin D and folic acid supplements should be offered by health staff to help avoid conditions such as rickets and spina bifida . Officials also called for local health officials to ensure equal support plans where mothers encourage new parents to breastfeed are set up. NICE also called for improvements in the care of pregnant women with diabetes. About 20;000 pregnancies each year are affected by diabetes and, therefore, carry, higher risk of miscarriage and still birth. The guidance said women should get access to advice and support, in particular to achieve good blood sugar control before they get pregnant. According to the passage, miscarriage is caused most probably by _ . | [

mmlu_train_22690 | They are most likely to be healthy, wealthy and wise, according to the old saying. But those who are early to bed and early to rise do not always have the upper hand, researchers say. They have revealed that night owls are generally brighter and wealthier than those able to get up early in the morning. 1 Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late demonstrated the kind of intelligence associated with honored jobs and higher incomes. 2 The researchers examined the habits and body clocks of the youngsters to determine whether they liked to stay up late and sleep in later in the morning, or preferred to go to bed early and were at their peak in the morning. 3 School performance and inductive intelligence, or problem solving, were measured and academic grades in the major subjects were also taken into account. The results showed that evening types scored higher than morning types on inductive reasoning, which has been shown to be a good estimate of general intelligence and a strong indicator of academic performance. 4 They also had a greater capacity to think conceptually as well as analytically. Such abilities have been linked to innovative thinking, more admired occupations and better incomes. Famous night owls include President Obama, Charles Darwin, Winston Churchill, Keith Richards and Elvis Presley. George W Bush, who is regularly in bed by 10pm, Thomas Edison, Napoleon, Condoleezza Rice, who wakes at 4.30am, and Ernest Hemingway are among those known as larks . Jim Horne, professor of psychophysiology at Loughborough University, said: 'Evening types tend to be the more active and creative types, the poets, artists and inventors, while the morning types are the deducers , as often seen with civil servants and accountants.' A previous study of US Air Force recruits found evening types were much better at thinking laterally to solve problems than larks. According to the passage, which of the following is true? | [

mmlu_train_25477 | How many hours do you spend sitting in a chair every day? Eight hours in the office plus three hours in front of the TV after work is the norm for many people. You probably don't need an expert to tell you that sitting too much is not good for your health--from an increased risk of heart disease and obesity in the long term,to reduced cholesterol maintenance in the short term,not to mention the strain on your neck and spine. To make matters worse,many researches show a good diet and regular exercise call't reduce the negative effects of sitting too much. A 2010 study of nearly 9,000 Australians found that for each additional hour of television a person watched per day,the risk of dying rose by 11 percent.Another study tracked the health of 123,000 Americans between 1992 and 2006.The death rate for men who spent six hours or more per day sitting was about 20 percent higher than for men who sat for three hours or less. So what can we do about it? Health experts suggest we break up those many hours spent sitting with more hours spent standing. The BBC conducted a simple experiment with a group of 10 volunteers who usually spent most of the day sitting.They were asked to stand for at least three hours a day.The researchers took measurements Oil days when the volunteers stood,and when they sat around.When they looked at the data there were some striking differences,the BBC reported. Blood sugar leveled off much quicker on the days when the study subjects stood compared with the days they spent in a chair.Standing also burned more calories----about 50 calories an hour.A member said although doing exercise offers many proven benefits,our bodies also need the increase in muscle activity that standing provides. The researchers believe that even small adjustments,like standing while talking on the phone,will help. What is the purpose of the experiment in the text? | [

mmlu_train_54995 | We've used the wind as an energy source for a long time. The Babylonians and Chinese were using wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that. Wind power was used in the Middle Ages, in Europe, to grind corn, which is where the term "windmill" comes from. We can use the energy in the wind by building a tall tower, with a large propeller on the top. The wind blows the propellor round, which turns a generator to produce electricity. We tend to build many of these towers together, to make a "wind farm" and produce more electricity. The more towers, the more wind, and the larger the propellors, the more electricity we can make. It's only worth building wind farms in places that have strong, steady winds, although boats and caravans increasingly have small wind generators to help keep their batteries charged. The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains - places where the wind is strong and reliable. Some are offshore. To be worthwhile, you need an average wind speed of around 25 km/h. Most wind farms in the UK are in Cornwall or Wales. Isolated places such as farms may have their own wind generators. In California, several "wind farms" supply electricity to homes around Los Angeles. The propellors are large, to obtain energy from the largest possible volume of air. The blades can be angled to cope with varying wind speeds. Some designs use vertical turbines , which don't need to be turned to face the wind. The towers are tall, to get the propellors as high as possible, up to where the wind is stronger. This means that the land beneath can still be used for farming. What can be a suitable title for the passage? | [

And sure enough, in 2009, at around the 36 kilometer point of the Beijing Marathon I experienced what runners call "hitting the wall". I had been doing well until that point, but suddenly I felt a sharp pain in my leg. My pace slowed down dramatically and every brain cell in my head seemed to be screaming "stop!!!" The last 5 kilometers were not fun; in fact, they were really hard work. Keeping motivated to run those last few kilometers was one of the hardest things I had ever done. But that is what makes running a marathon such a rewarding experience -- if it were easy everyone would do it. I have to admit it is sometimes not even easy to find the motivation to get out of bed, pull on your running shoes and head out into the morning to go for another run.

mmlu_train_86052 | Everybody hates rats. But in the earthquake places of the world - Japan, Los Angeles, Turkey - rats will soon be man's new best friends. What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can't get into small spaces. So now a new research project is using a smaller animal to save lives: the rat. How does it work? First, the rat is trained to smell people. When this happens, the rat's brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat's brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person. Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, " 'Robot' noses don't work well when there are other smells around. Rats are good at that." Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don't need electricity. The " rat project" is not finished, but Julie Ryan of International Rescue Corps in Scotland says, " It would be fantastic. A rat would get into spaces we couldn't get to and a rat would get out if it wasn't safe."

mmlu_train_21081 | In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us. Studies have shown. for instance. that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues( ). like plate size and lighting, have been shown to affect portion size and consumption. A new study suggested that our shot-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they'd eaten but rather by how much food they'd seen in front of them --- in other words, how much they remembered eating. This difference suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal. says Jeffrey M . Brunstrom , a professor of experimental psychology at the University of Bristol. "Hunger isn't. controlled solely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal." Brunstrom says. "This shows that the relationship between hunger and food intake is more complex than we thought." These findings echo earlier research that suggests our perception of food can sometimes trick our body's response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie milkshake on two separate occasions produced different levels of hunger-related hormones, depending on whether the shake's label said it contained 620 0r 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake. What does this means for our eating habits? Although it hardly seems practical to trick ourselves in to eating less, the new findings do highlight the benefits of focusing on our food avoiding TV and multitasking while eating. The so-called mindful-eating strategies can fight distractions and help us control our appetite, Brunstrom says. What does Brunstrom suggest we should do to control our appetite? | [

mmlu_train_69134 | Food wasting is often seen in China. It's reported that food waste has produced 70% of the country's increasing rubbish. Especially in restaurants, plenty of food is wasted every day. Huge food waste is usually seen in wedding banquets , birthday banquets and business meals. However, when many people waste food, there is still a large number of people who do not have enough food to eat. Luckily, when dining out is part of everyday life, more and more people have realized packing up the leftovers when dinning might be the right thing to do. Now here is some advice about how. When packing leftovers, take staple foods such as steamed bread. However, leftovers of cold dishes should not be packed up, because the cold dishes can not be heated after being brought home and may go bad and cause illness. Also, leftovers should be kept in the right way after being brought home. Food should be kept at temperatures below 10 degC or higher than 70 degC.But if the packed food is put under room temperatures, they should be eaten within four hours. Packing leftovers in the right way is important, but it's more important to know how to order the right number of dishes. Don't be afraid of losing face by ordering less. After all, food doesn't come easily. What's passage mainly about? | [

mmlu_train_61322 | Smoking is the single worst thing you can do for your health. Fortunately, it's never too late to get the benefits of quitting. If you've tried to quit before and failed, it's time to make up your mind and try again. Smoking is responsible for one of every five deaths. That includes 29% of all cancer deaths, 87% of all lung cancer deaths, and nearly 20% of all deaths from cardiovascular disease. But long before smoking kills you, it ages you. You can see for yourself that smoking accelerates the drying and wrinkling of the skin. But there are less obvious effects as well. Indeed, smoking takes years away from your life. Nearly half of all chronic smokers die an average of 20 to 25 years before their time. Besides an early death from cancer or heart disease, smoking can cause lung disorders. People who smoke over a pack a day have almost three times the risk of contracting pneumonia than that of nonsmokers. By lowering levels of estrogen in men and women, smoking speeds bone less. If a woman smokes a pack of cigarettes every day, she will enter menopause with 5 to 10% less bone mass than a nonsmoker. The good news is that no matter what your age is or how long you've smoked, you'll live longer if you quit today. The Coronary Artery Surgery Study examined nearly 2,000 long-term smokers over age 54. Those who quit had significantly lower death rates six years later than those who didn't. Even the oldest ex-smokers had a higher survival rate. Not only will live longer if you quit, you'll feel better, breathe easier, and find that you have more energy. You'll have fewer respiratory infections,headaches, and stomachaches. What's more, you'll save money. Your clothes and breath won't smell unpleasant any longer. And your habit won't annoy--or threaten the health of --the people who live and work with you. According to the passage, the percentage of deaths due to smoking is _ . | [

mmlu_train_37463 | More than a decade ago, cognitive scientists John Bransfgord and Daniel Schwartz, both then at Vanderbilt University, found that knowledge was not the ability to retain facts or apply previous knowledge to a new situation but a quality they called "preparation for future learning." The researches asked fifth graders and college students to create a recovery plan to protect bald eagles from extinction. Shockingly, the two groups came up with plans of similar quality (though the college students had better spelling skills). From the standpoint of a traditional educator, this outcome indicated that schooling had failed to help students think about ecosystems and extinction, major scientific ideas. The researches decided to go deeper, however. They asked both groups to generate questions about important issues needed to create recovery plans. On this task, they found large differences. College students focused on critical issues. The college students had cultivated the ability to ask questions, the foundation of critical thinking. They had learned how to learn. Museums and other institutions of informal learning may be more suitable to teach this skill than elementary and secondly schools. At the Exploratorium in San Francisco, we recently studied how learning to ask good questions can affect the quality of people's scientific inquiry. We found that when we taught participants to ask "What if?" and "How can?" questions that nobody present would know the answer to and that would spark exploration, they engaged in better inquiry at the next exhibit--asking more questions, performing more experiments and making better interpretations of their results. Specially, their questions became more comprehensive at the new exhibit. This type of learning is not limited to museums of institutional settings. Informal learning environment tolerate failure better than schools. Perhaps many teachers have too little time to allow students to form and pursue their own questions and too much ground to cover in the curriculum. But people must acquire this skill somewhere. Our society depend on them being able to make critical decisions about their own medical treatment, says, or what we must do about global energy needs and demands. For that, we have a robust informal system that gives no grades, takes all comers, and is available even on holidays and weekends.

mmlu_train_42654 | Many people enjoy an adventure story. Others like mysteries that lead the reader to an exciting discovery. The story of the young British naturalist Charles Darwin combines both of these. That is why the author and illustrator Rosalyn Schanzer chose to write the children's book "What Darwin Saw". The book was published just in time for the 200th anniversary of Charles Darwin's birth on February 12, 1809. Rosalyn Schanzer carefully gathered Darwin's thoughts and observations from his diaries, letters and books. Many of the words in the book are Darwin's own. She also traveled to the Galapagos Islands and South America. She researched some of the places Darwin had visited on his trip on the ship, the Beagle in the 1830s. She took thousands of pictures, which helped her create the book's beautiful and color1ful drawings. These pictures show young readers what led Darwin to form his great discovery: the evolution of species through natural selection. "What Darwin Saw" tells of the adventures of a young man who traveled around the world as a scientist. The voyage of the Beagle took Charles Darwin to South America, where he rode horses with cowboys and met Native Americans in Argentina. He reported the eruption of the Osorno Volcano and experienced an earthquake in Chile. Darwin's observations showed him that environments can change very quickly and a great deal over time. Rosalyn Schanzer brings to life the clues that suggested to Darwin that living things evolve, or change, over time. She illustrates the unusual tortoises, birds and lizards that Darwin studied in the Galapagos Islands. She shows how Darwin came to understand that these island animals had differences, developed over time, that helped them survive. And she explains the theory of evolution through natural selection in a way that both children and adults will enjoy. Rosalyn Schanzer took thousands of pictures in order to _ . | [

mmlu_train_75901 | TOKYO, JAPAN--What do you do when you see a cockroach ? Do you hit it with a newspaper? Do you step on it? When researchers at Tokyo University see a cockroach, they take the remote control and make the cockroach turn around, run left or right, or go forward. These scientists are changing the cockroaches into robots. Each cockroach has a very small pack that has in it a microprocessor .Then researchers can send signals from the remote control to the pack. The signals control the movements of the cockroaches. Why does anyone want to control a cockroach? "Insects can do many things that people can't," says Isao Shimoyama, head of robot research at Tokyo University. In a few years, he says, these robot insects will carry very small cameras. They will be able to move through earthquake rubble to look for people or move under doors to find information about someone. This may seem strange, but the Japanese government thinks the research is very important. The government is giving the scientists $ 5 million for this research. First, the researchers breed hundreds of cockroaches. They use only the American cockroach because it is bigger and stronger than other cockroaches. Then they choose the best cockroaches and remove their wings and antennae . They put small packs where the antennae were. The packs weigh about three grams, or about two times the weight of the cockroaches themselves. "Cockroaches are very strong," says Ralph Holzer, who is a researcher at Tokyo University. "They can lift 20 times their own weight. " With a remote control, the scientists send signals to the packs. When a cockroach gets the signal, it moves. The problem is that the cockroaches don't always move in the right direction. What problem do the rcscarchcrs meet with? | [

They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior. In colonies that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone , chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit. In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs.

mmlu_train_49453 | Career success could be predicted as early as kindergarten, according to a 20-year study recently published in the American Journal of Public Health. Researchers from Pennsylvania State University and Duke University tracked more than 700 children from across the US between kindergarten and age 25 and found a significant correlation between their social skills as kindergartners and their success as adults two decades later. In 1991, teachers assessed how the kindergartners interacted with each other socially using a range of criteria like whether they cooperate with their peers without prompting , if they're helpful to others, whether they're good at understanding feelings, and if they can solve problems on their own. Researchers then kept track of whether the students went on to graduate high school on time, get a college degree, and find and keep a full-time job by 25. They also monitored the participants' involvement with crime, drug abuse, public assistance, and mental health issues. The results showed that socially competent children were far more likely to earn a college degree and have a full-time job by 25 than those with limited social skills. Those with limited social skills also had a higher chance of getting arrested, binge drinking, and applying for public housing. "This study shows that helping children develop social and emotional skills is one of the most important things we can do to prepare them for a healthy future," said Kristin Schubert, program director at the Robert Wood Johnson Foundation, which funded the research, in a release. "From an early age, these skills can determine whether a child goes to college or prison, and whether they end up employed or addicted." The good news, according to Damon Jones, lead author of the study, is that intervention at a young age can help improve social and emotional skills. "This research by itself doesn't prove that higher social competence can lead to better outcomes later on," he said. "But when combined with other research, it is clear that helping children develop these skills increases their chances of success in school, work, and life." What has the 20-year study found? | [

mmlu_train_66093 | Teens who become addicted to their cellphones may be placing their health at risk by harming their ability to sleep well,a new Swedish study suggests. "The message is that teenagers who use their cellphones excessively are much more stressed, much more restless, much more tired, and have a great tendency to develop sleep deprivation as a result of their calling habits, " said the study author Dr. Gaby Bader. He focused on the experiences of 21 healthy Swedish boys and girls between the ages of 14 and 20. The teens kept what the authors described as "regular working/studying hours" and were not previously diagnosed with any particular sleep irregularity. He observed that the above-15 call group kept more irregular sleeping hours than the lower-use group,had more difficulty falling asleep,more difficulty waking up,and experienced more sleep disruptions . Bader said that among young people,a ly recent technological invention like the cellphone has quickly become existed nearly everywhere,giving rise to considerable pressure to keep in touch. And this pressure can develop into an addiction,with serious negative results for teenager health. "We see more and more people--especially the young generation-- who grew up with these kinds of items and gadgets in their hands," Bader said. "And they become dependent on the technology. So,we have to teach young people to be structured. To know when to have the cellphone on,and when to switch it off. To avoid becoming the slave of technology,instead of the master. " Dr. Mary Carskadon expressed little surprise with the finding. " Interpersonal contact is one of the things that's best at keeping us awake," she observed. "And so,a young person receiving cellphone texts or phone calls is going to have more deep disturbances. And they are going to be tired and restless,and probably,as a result,going to use more stimulants .And judgment is not always the best in our teenage years. So, that's where I think parental attention to this issue may be useful. " According to Dr. Mary Carskadon,how to deal with the problem? | [

mmlu_train_90447 | Many companies use guards and expensive alarm systems to protect their property . Soon a new kind of protection will be used--robots. Engineers have been working on the first mobile robots for businesses. The robots will guard factories, warehouses and museums at night. The mobile robots will move around slowly on wheels. They will be able to detect(,) people through walls and pick up sounds, such as breaking glass. They can be fixed with loud sirens to frighten thieves, or radios to signal police or guards. To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot's small, built-in computer. A floor map could be programmed into the computer's memory, for example. A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won't be able to tell the difference between friends and enemies. Because of that, people will have to be prevented from entering the area it moves. One kind of mobile robot will be able to "sense" whether a chair or a box has been moved and go around it. This robot will also judge size well enough so that it won't send an alarm if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot is hard to be stolen anyway. It weighs about 200 pounds. U.S. companies pay almost $10 billion a year to protect their property with alarm systems and human guards.

mmlu_train_19823 | Bamboo is one of the nature's most surprising plants. Many people call this plant a tree, but it is a kind of grass. Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe . There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains. Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green. Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong. In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills can help to make the poor thirsty fields be watered. How is bamboo like grass? | [

mmlu_train_24805 | Eating a diet high in processed food increases the risk of depression , research suggests. What's more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found. Data on diet among 3,500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants into two types of diet--those who ate a diet largely based on whole food,which includes lots of fruit, vegetables and fish,and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat,refined grains and high fat dairy products After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic diseases, they found a significant difference in the future depression risk with the different diets. Those who ate the most wholefood had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58% higher risk of depression than those who ate a diet low in processed foods. Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by lifestyle factor they had not accounted for. He also pointed in a paper that a Mediterranean diet was associated with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood of you eating a Mediterranean diet is not very high. Dr.Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health. He added people's diets were becoming increasingly unhealthy. The UK population is consuming less nutritious, fresh produce and more saturated fats and sugars.

mmlu_train_66727 | Everyone knows how a fishing calendar works: it tells you when you have the best chance of catching the most fish. This year, though, Kelson Poepoe, a conservationist on Hawaii's prefix = st1 /MolokaiIsland, helped publish an unusual version on this model. Poepoe and his colleagues decided to print a calendar telling people when not to fish. Many of the Homestead's residents still follow an existence lifestyle, gathering roughly one-third of their food by fishing in nearby Mo'omomi Bay. But, even though overfishing has exhausted fish populations throughout Hawaii, Mo'omomi Bay's fishery is booming, with a higher fish density than nearly anywhere else in the main islands. The new calendar is based on the ancient fishing practices that have helped keep those populations strong. Hawaiians have long known that carefully tended resources will renew themselves. To make this process easier, fishermen traditionally worked hard to understand and adapt to fish behavior. For example, they closely monitored where and when key species gathered to reproduce, and they prevented fishing during those times. By contrast, most of today's fishermen see spawning periods as a chance to get large numbers of fish, which can cause population break down. While these traditional methods have largely died out, they are still practiced by Poepoe and his fellow men at Mo'omomi Bay. "We have a rule of conduct that basically says, take only what you can eat fresh, don't stock your fridge, and don't take the fish when they spawn," Poepoe said. In 1993, Poepoe helped found the conservation group Hui Malama Mo'omomi to teach _ to new generations, and publishing the calendar is a key part of this move. It follows the lunar cycle, declaring when certain species are not available or "taboo." It also includes helpful hints about fish lifecycles, detailing exactly where in the bay certain kinds of fish like to gather, how to tell males from females, and which fishing methods are least likely to harm fish populations long-term. So far, these methods have helped keep Mo'omomi Bay's fish number totals far higher than elsewhere in the surrounding islands. With hopes of copying this success, a number of local groups are interested in creating similar calendars for other coastal areas. But that's a difficult project, partly because fish habits are highly local, meaning that the information in the calendar applies mainly to Mo'omomi Bay. Still, these groups believe the basic methods are transferable. To use a similar new calendar for other coastal areas, people have to _ . | [

mmlu_train_91276 | Health officials in Canada are very busy these days. They are placing chickens at fixed points all along their 2,500 km border with the United States of America. It's not a joke, nor have the Canadians gone mad. They are using these chickens to see if the West Nile virus is still around. The virus infects birds, so the chickens have a chance of catching the virus and fall ill. The West Nile virus is spread among humans. It killed seven people in New York last year. Countries around the world are realizing that it may just be possible to stop certain kinds of people from entering their land. However, it is very difficult to stop viruses traveling from one end of the earth to another. When they travel to new places, they get used to the environment very easily and sometimes start destroying the local plant and animal life. These biological polluters are called smart polluters. These smart polluters can be carried across borders of countries unknowingly. Just as we humans are travelling across the world more often than earlier, these biological polluters have also started journey much more. They slide into airplanes through their wheels. They dig into objects that travelers may be carrying from one country to another. There are some good examples of how these polluters work. The water hyacinth of South America is blocking lakes in China and Africa. Tree snakes from Papua New Guinea are busy eating up some birds in the country of Guam, which breaks its natural balance. That's why the customs officials in many foreign countries prevent people from bringing in a small plant, or an object made of wood that is in its natural form. The customs officials have these rules because these varieties of plants are special to certain places. The plants have the power to spread new illnesses among native plants and animals. Biological polluters always create problems in places where they do not belong. They could be special varieties of plants, bugs or even animals. Which of the following is TRUE? | [

Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those of people who didn't drink diet soda."What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler. The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly l0 years. While the findings are surprising, they also offer some explanations. Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet soda, they don't lose weight at all."We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers. So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet soda, and so over-compensate for the missing calories( ). A related study found some sweeteners raised blood sugar levels in some mice." Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said study researcher Helen P.Hazuda, professor at the University of Texas's school of medicine.
