mmlu_train_28402 | An allergy is a strong reaction to a substance. Many things can cause allergies. The most common cause is pollen , which is usually produced by trees in the spring, grasses in the summer and weeds in the fall, as part of their reproductive process. Other causes include organisms, chemicals, plants and dead skin particles from dogs and cats can also cause allergic reactions. So can insect stings and some food. The most common kind of allergic reactions is itchy , watery eyes and a blocked or watery nose. Allergies can also cause red, itchy skin. Some reactions can be life-threatening, for example, when breathing passages become blocked. It is not always easy to avoid allergies. Drugs may offer an effective treatment. Another treatment used in some cases is called immunotherapy. A patient is injected with small amounts of the allergy-causing substance. The idea is that larger and larger amounts are given over time until the patient develops resistance in his body. In the United States, experts estimate that up to 8% of young children have food allergies. Every year these allergies cause about 30,000 cases with severe reactions that require immediate treatment. It can result in breathing trouble and in some cases death. It is said that about 100 to 200 people will die. It is said that most of the reactions are caused by peanuts and tree nuts like walnuts. People can also be allergic to medicines. The American Academy of Allergy, Asthma and Immunology says about 10% of bad reactions to commonly used medicines are allergic. In other words, a person's immune system overreacts and produces an allergic reaction. The most common reactions include skin rashes, itching, breathing problems and swelling in areas such as the face. The best title would be _ . | [

mmlu_train_12748 | Have you ever looked toward the sky on a fall day and witnessed a group of migrating birds? If so, you probably noted the V-shaped formation of the birds or the birds flying in a ball-like formation. Why do birds fly this way? Many theories have been developed to explain the formation patterns of different types of birds. One theory is that birds fly in certain formations to take advantage of the laws of nature. The birds know that flying in a V-shaped pattern will save energy. Like the lead cyclist in a race who decreases wind force for the cyclists who follow, the lead bird cuts wind force for the birds that follow. This decrease in wind force means that the birds use up to 70 percent less energy during their flight. When the lead bird becomes tired, a more rested bird takes over that position. But saving energy is important for more than one reason. Sometimes food is short during migration flights. Keeping energy enables the birds to fly longer distances between meals. When food is sighted, the birds guide one another in a different way. When a bird identifies a familiar feeding area, it might turn around in order to signal the group to change direction. Then, this bird becomes the new leader. It helps guarantee that other birds will know exactly where it is going. Then the whole group makes a change in direction, gently streaming from the sky down to the ground. This formation is like an arrow pointing to the location of food. Scientists have also studied the birds that sometimes fly in a ball-like formation. Researchers believe that the birds come together if a predator is spotted. The predator may then become impatient waiting for a single bird to fly away from the group. The birds will often dip and dive as a group, frustrating even the most persistent enemy. Scientists report that this is a very effective method of defense against an attack. The birds care for their fellow fliers through teamwork. As transportation expert Henry Ford once said, "If everyone is moving forward together, then success takes care of itself." When it comes to teamwork, these feathered fliers are a soaring success!

mmlu_train_13860 | Technology is changing our lives. Our present aerospace companies are gradually disappearing as private space concerns are being born every day. I'm going to discuss three spacebased businesses that are sure to soon influence us all. First we have to make space travel cheaply and safely. Engine design is the main challenge. To make money in space, the cost of space travel will have to diminish . This problem will be the most difficult to solve. Liquid fueled rockets are the only way to get out of Earth's orbit. Finding new ways to power the flight to space is also another big challenge. Finding the key to cheap space travel might be the biggest story of our times. There are a lot of great minds working on this problem. And companies are pouring money into research and development. In the next few years we'll see the first suborbital tourist. And not long after that we should really start to see new and exciting things as competition heats up. Spacecraft design and production will naturally follow rocket technology. All sorts of crafts will be needed for the wide uses they'll be tasked with. Several companies in the United States have already made small, lowcost test vehicles. Resources in space will provide great mining profits to those who can afford the cost of setting up such a huge operation. Can you imagine finding a huge asteroid of pure gold? The benefit to mankind is limitless. Mining on other planets, like Mars, also adds CO2 into the very thin atmosphere. Over time this can lead to the formation of an atmosphere similar to Earth's. Space is going to offer us untold opportunity and wealth. But this is only going to occur if wealthy investors step forward and fund the first steps forward. It is certain that technology will take us to worlds we could never have imagined. What should be done first to make travel in space cheap and safe? | [

mmlu_train_57490 | Two American scientists told the people in industrial nations that they would be much healthier if they ate more of the same kind of foods eaten by humans living more than 10,000 years ago. The scientists say that the human body has changed very little since human first appeared on the earth,but the way we live has changed greatly. Our body has not been able to deal with these changes in lifestyles and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times. So they are called "diseases of civilization ".Many cancers and diseases of the blood system,including heart attacks and strokes are examples of such diseases. Scientists noted that early stoneage people used very little alcohol or tobacco ,probably none. Ancient people also got a great deal of physical exercise,but a change in food is one of the main differences between life in ancient times and life today. Stoneage people hunted wild animals for their meat ,which had much less fat than farm animals. They also ate a lot of fresh wild vegetables and fruits. They did not use milk and other dairy products ,and they made very little use of grains . But today,we eat a large amount of dairy products and grain foods. We eat six times more salt than stoneage people. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C. People today probably do not want to live as people thousands of years ago did,but scientists say that we would be much healthier if we ate as those ancient people did,cutting the amount of fatty,salty and sweet foods.

mmlu_train_47053 | How many things can you see in the night sky? A lot! On a clear night you might see the Moon, some planets, and thousands of sparkling stars. You can see even more with a telescope. You might see stars where before you only saw dark space. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescope you can see more and more objects in the sky. And you can see those objects in more and more detail. But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year. That's because they're invisible. They're the mysterious dead stars called black holes. You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years. As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die. As the star cools, the outer layers of the star pull in toward the center. The star squashes into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe. Imagine if the Earth were crushed until it was the size of a tiny marble . That's how tightly this dead star, a black hole, is packed. What pulls the star in towards its center with such power? It's the same force that pulls you down when you jump - the force called gravity. A black hole is so tightly packed that its gravity sucks in everything - even light. The light from a black hole can never come back to your eyes. That's why you see nothing but blackness. So the next time you stare up at the night sky, remember: there's more in the sky than meets the eyes! Scattered in the silent darkness are black holes - the great mystery of space. Why can't you see light when you look at a black hole? | [

mmlu_train_51423 | He wanted to go to college, and the only thing that might have stopped him was his disability. But this year, Zhang Yan and other physically disabled kids can realize their dream just like any other students. As registration for this year's college entrance examinations draws near, the government has loosened its requirements on physical examinations for new college students. A new rule was jointly decided in March by the Ministry of Education, the Ministry of Health and the China Disabled Persons' Federation. It clearly states that no student should be rejected simply because they have a physical disability. Schools may still advise disabled students on the choice of their major if it is likely to affect their future chances of employment. However,the final decision will be up to the student., "Now I can just go ahead and do my best in the exams.

mmlu_train_16242 | If you are a high school senior graduating and looking to enter college in 2006, you will take the new exam. The biggest change to the SAT will be the introduction of a new writing section. The writing section will consist of two parts: an essay and a multiple-choice section. Students will be given 25 minutes to respond to a prompt and construct a well-organized essay that effectively deals with the task. The essay question may require students to complete a statement, to react to a quote, or to agree or disagree with a point of view. In any case, a good essay will support the chosen position with specific reasons and examples from literature, history, art, science, current affairs, or even a student's own experiences. Essays will be scored based on the procedures for the current SAT II: Writing Test. Essays will be graded by two independent readers On a scale of 1~6, and their two scores will be combined to form an essay subscore that ranges from 2 to 12. Should the readers' scores vary by more than 2 points, a third reader will score the essay; The readers will be high school teachers and college professors who teach composition. To ensure that essays will be scored in a timely manner, they will be scanned and made available to readers on the Internet for grading purpose. The writing section will also include multiple-choice grammar and usage questions. Some of these questions will call upon students to improve given sentences and paragraphs. Others will present students with sentences and require them to identify mistakes in diction , grammar, sentence construction, subject-verb agreement, proper word usage. The highest possible score on the new writing section will be 800. Scores on the essay and multiple-choice section will be combined to produce a single score. A writing subscore will also be assigned. The highest possible scores on the Critical Reading and Math sections will remain 800 each, making 2,400 a perfect score on the new SAT.

mmlu_train_57220 | As a boy, Sanders was much influenced by books about the sea, but by the age of fifteen he had decided to become a doctor rather than a sailor. His father was a doctor. So he was often with the doctors and got along very well with them. When he was fourteen, he was already hanging around the hospital where he was supposed to be helping to clean the medicine bottles, but was actually trying to listen to the doctors' conversations with patients in the next room. During the war Sanders served in the army as a surgeon . "That was the happiest time of my life. I was dealing with real sufferers and on the whole making a success of my job." In Rhodes he taught the country people simple facts about medicine. He saw himself as a life-saver. He had proved his skill to himself and had a firm belief that he could serve those who lived simply, and were dependent upon him. Thus, while in a position to tell them what to do he could feel he was serving them.

mmlu_train_9891 | Nanotechnology is a fashionable word these days. The name "nano" comes from the size of molecules, which are measured in nanometers--or one billionth of a meter. Through operating the atoms and molecules, scientists can change the nature of common materials and even create new materials that have new properties. But scientists are concerned about its possible risks to our daily lives. Clothing merchants claim their nanocloth keeps our bodies warmer in winter, saving us from needing thick coats. Vitamin companies boast their nanopills are easier to absorb. Home decoration companies suggest you use their nanopaint, which has no smell, is waterproof, and free from poisonous substances. Nanomaterials are making our lives better, its creators say. The US National Science Foundation predicts nanotechnology research will grow into a US $-trillion industry over the next 10 years. But ly little is known about the potential health and environmental effects of the tiny particles. Just atoms wide, they are small enough to penetrate cells easily in lungs, brains and other organs. US bestseller "Prey", written by Michael Crichton, paints a doomsday in which a group of tiny nanomachines escapes the lab and threatens to take control of humanity. Studies have shown that some nanoparticles can be poisonous to animal cells. There are fears that exposure can cause breathing problems, since nanoparticles could be taken in through the nose, causing unknown problems to brain cells. Scientists also fear that nanoparticles placed on the skin could damage DNA. "No one knows, and that's the problem," said Pat Mooney, director of the ETC Group.

mmlu_train_51994 | Engineering students are supposed to be examples of practicality and rationality ,but when it comes to my college education I am an idealist and a fool. In high school I wanted to be an electrical engineer and, of course, any reasonable student with my aims would have chosen a college with a large engineering department, many famous professors and lots of good labs and research equipment. But that's not what I did. I chose to study engineering in a small liberal-arts university that doesn't even offer a major in electrical engineering. Obviously, this was not a practical choice; I came here for more noble reasons. I wanted a broad education that would provide me with flexibility and a value system to guide me in my job. I wanted to open my eyes and expand my vision by communicating with people who weren't studying science or engineering. My parents, teachers and other adults praised me for such a wise choice. They told me I was wise and grown-up beyond my 18 years, and I believed them. I headed off to the college and sure I was going to have an advantage over those students who went to big engineering "factories" where they didn't care if you had values or were flexible. I was going to be a complete engineer: technical expert and excellent humanist all in one. Now I'm not so sure. Somewhere along the way my noble ideas crashed into reality, as all noble ideas finally do. After three years of struggling to balance math, physics and engineering courses with liberal-arts courses, I have learned there are reasons why few engineering students try to reconcile engineering with liberal-arts courses in college. The reality that has blocked my path to become the typical successful student is that engineering and the liberal arts simply don't mix as easily as I supposed in high school. Individually they shape a person in very different ways. The struggle to reconcile the two fields of study is difficult. What problem has the writer found in his study at college? | [

mmlu_train_46021 | Trees should only be pruned when there is a good and clear reason for doing so and , he number of such reasons is small . Pruning involves the cutting away of overgrown and unwanted branches , and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way . First , pruning may be done to make sure that trees have desired shape or size . The object may be to get a tree of the right height , and at the same time to help the growth of small side branches , which will thicken its appearance or give it a special shape . Secondly , pruning may be done to make the tree healthier . You may cut out diseased or dead wood , or branches that are rubbing against each other and thus cause wounds . The health of a tree may be encouraged by removing branches that are blocking up the center and so preventing the free movement of air . One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease , but it is a wound that will heal . Often there is a race between the healing and the disease as to whether the tree will live or die , so that there is a period when the tree is at risk . It should be the aim of every gardener to reduce that risk of death as far as possible . It is important to make the area , which has been pruned , smooth and clean , for healing will be slowed down by roughness . You should allow the cut surface to dry for a few hours and then paint it with one of the materials available from garden shops produced especially for this purpose . Pruning is usually done in winter , for then you can see the shape of the tree clearly without interference from the leaves and also it is very unlikely that the cuts you make will bleed .

mmlu_train_29351 | You're not doomed to toss and turn every night. Although you might not be able to control all of the factors that relate to your sleep, you can adopt habits that encourage better sleep. Start with these simple sleep tips. No. 1: Stick to a sleep schedule Go to bed and get up at the same time every day, even on weekends, holidays and days off. Being consistent reinforces your body's sleep-wake cycle and helps promote better sleep at night. If you don't fall asleep within about 15 minutes, get up and do something relaxing. Go back to bed when you're tired. No. 2: Pay attention to what you eat and drink Don't go to bed either hungry or stuffed. Your discomfort might keep you up. Also limit how much you drink before bed, to prevent disruptive middle-of-the-night trips to the toilet. Nicotine, caffeine and alcohol deserve caution, too. The stimulating effects of nicotine and caffeine -- which take hours to wear off -- can ruin quality sleep. No. 3: Create a bedtime ritual Do the same things each night to tell your body it's time to wind down. This might include taking a warm bath or shower, reading a book, or listening to light music. Be careful of using the TV or other electronic devices as part of your bedtime ritual. Some research suggests that screen time or other media use before bedtime has impact on sleep. No. 4: Get comfortable Create a room that's ideal for sleeping. Often, this means cool, dark and quiet. Consider using room-darkening shades, earplugs, a fan or other devices to create an environment that suits your needs. Your mattress and pillow can contribute to better sleep, too. Since the features of good bedding are subjective, choose what feels most comfortable to you. If you have children or pets, set limits on how often they sleep with you -- or insist on separate sleeping quarters. No. 5: Limit daytime naps Long daytime naps can affect nighttime sleep -- especially if you're struggling with poor sleep quality at night. If you choose to nap during the day, limit yourself to about 10 to 30 minutes and make it during the mid-afternoon. If you work nights, you'll need to make an exception to the rules about daytime sleeping. In this case, keep your window coverings closed so that sunlight -- which adjusts your internal clock -- doesn't interrupt your daytime sleep. No. 6: Include physical activity in your daily routine Regular physical activity can promote better sleep, helping you to fall asleep faster and to enjoy deeper sleep. Timing is important, though. If you exercise too close to bedtime, you might be too energized to fall asleep. If this seems to be an issue for you, exercise earlier in the day. No. 7: Manage stress When you have too much to do -- and too much to think about -- your sleep is likely to suffer. To help restore peace to your life, consider healthy ways to manage stress. Start with the basics, such as getting organized, setting priorities and dividing tasks. Give yourself permission to take a break when you need one. Share a good laugh with an old friend. Nearly everyone has an occasional sleepless night -- but if you often have trouble sleeping, contact your doctor. Identifying and treating any underlying causes can help you get the better sleep you deserve. According to the passage, in what situation do you need to contact your doctor? | [

mmlu_train_11808 | About 6 percent of luxury hotels in three major Chinese cities have stopped serving shark fin ,a survey has found. Although the controversial dish remains on the menu at most hotels, Green Beagle Environment Institute, a Beijing-based non-government organization that was the main sponsor of the survey, said the results are encouraging and reflect increased awareness. The survey was carried out in Beijing, Shenzhen and Fuzhou, which were selected as representative cities to collect basic data on shark fin consumption nationwide. In Beijing, 132 hotels completed the phone questionnaire between Nov. 20 and Dec. 12. Only 12 hotels, 9 percent, said they do not serve shark fin. A similar survey of 131 Beijing hotels conducted a year ago found only one hotel that did not serve shark fin, Wang Xue, chief coordinator of the survey, said on Saturday.In Shenzhen, four out of the 85 four and five star hotels surveyed had stopped serving shark fin, accounting for about 5 percent. In Fuzhou, only one of the 40 hotels surveyed did not serve shark fin. On average, about 6. 61 percent of the hotels in the three cities did not serve the food. "The survey reminded us there is still a long way to go to remove shark fins from Chinese hotels and restaurants, but the improved situation in Beijing is encouraging," said Wang. "We found more hotels and restaurants were willing to take action over the past year." International hotels are more active in the "shark-fin-free" project, she noted. China is the world's biggest importer and consumer of shark fin, which has been used in luxurious Chinese dishes for 500 years. Dishes made from shark fin are still regarded as a symbol of honor and respect,especially at business dinners, according to Wang. Research has also found that shark fin contains poisonous elements, but the nutritious value is less than that of chicken or pork. "We hope hotels and restaurants remove shark fin products from their menus," Wang added. Why do Chinese people are fond of eating shark fin? | [

mmlu_train_50229 | One of India's top engineering schools has restricted Internet access in its boarding houses, saying addiction to surfing, gaming and blogging was affecting students' performance, making them lonely and even suicidal. Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. "Now, a student doesn't even know who lives two doors away from him because he is so busy on the Internet," said Prakash Gopalan, dean of student affairs. "The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion." IIT-Mumbai, with about 5,000 students, is one of seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional lifestyles are known to be common among IIT students, and at least nine have committed suicide in the past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming. Starting Monday, Internet access will be banned between 11 p.m. and 12.30 p.m. at IIT-Mumbai's 13 boarding buildings to encourage students to sleep early and to try and force them out of their "shells", Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. "Now they will say we need to listen to a lullaby to go to sleep," said Rajiv, an electronics student.

mmlu_train_53216 | Tears came into this mother's eyes when she talked about waking up her son. Every morning, her ten-year-old boy puts up one finger with his eyes still closed, begging for one more minute to sleep. Why is he so sleepy? Because, like thousands of student "early birds" in China, he has to get up before 6 a.m. every morning. School students usually need eight to ten hours' sleep a night. But in Shanghai, it's reported that 90% of the students do not get enough sleep. And studies show that without a good night's sleep, students seem to be weaker than they should be. Many become near-sighted as a result. Li Ming, a student at Qinghua High School, said that he usually goes to bed after 11 p.m. But when he has exams coming up, he can stay up as late as midnight. This "night bird" lifestyle has made many students nod off in class. Li Ming said that it is during afternoon classes that he feel most sleepy. "My parents are usually happy to see me studying so late," he said. "They think I work very hard and they make me cups of coffee." However, not all parents are happy about this.

mmlu_train_36342 | Learning a second language can improve brain power, scientists believe. US researchers from Northwestern University say bilingualism is a form of brain training -- a mental "work out" that adjusts the mind finely. Speaking two languages well affects the brain and changes how the nervous system reacts to sound, lab tests showed. Experts say the experiment performed by the National Academy of Sciences provides "biological" evidence of this. In an attempt to prove the guess that speaking two languages is good for one's mind, the team monitored how the brain of 48 healthy student volunteers reacted to different sounds. Twenty three of these volunteers were bilingual. The scientists used special equipment to trace the pattern of brainwaves. Under quiet, laboratory conditions, the bilingual students responded in a similar way to the English-only-speaking students, who formed the control group. But the bilingual group were far superior at processing sounds even when there were a lot of people talking in the room. They were better able to focus on to the important information -- the speaker's voice -- and block out other _ noises. Prof Nina Kraus, who led the research, said: "The bilingual's better experience with sound results in a hearing system that is highly efficient, flexible and focused in its automatic sound processing, especially in challenging or novel listening conditions." Co-author Viorica Marian said: "People do crossword puzzles and other activities to keep their minds sharp. But the advantages we've discovered in double language speakers come automatically simply from knowing and using two languages.'' Musicians appear to gain a similar benefit when rehearsing , say the researchers. According to some theories, being bilingual might help avoid dementia .

mmlu_train_59949 | How to Study Smarter, Not Harder Here are some of our favorite study tips that will help any student study smarter, not harder: Recite As You Study Reciting--saying things out loud should first take place as you read through each paragraph or section. Test yourself. This will help you to understand as well as learn faster because it is more active than reading or listening. It will also help you to notice your mistakes and the topics you have trouble understanding. Take Fuller Notes Notes should be in your own words, brief and clear. They should be tidy and easy to read. Writing notes will help you better than just underlining as you read, since it forces you to rewrite ideas in your own words. Study the Middle The best time to review is soon after you've learned something. You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review. Sleep On It Study before going to bed, unless you are very tired. It's easier to remember material you've just learned after sleeping than after an equal period of daytime activity, because your brain continues to think even after you've fallen asleep. Combine Memory and Understanding There are two ways to remember: by memorizing and by understanding. Multiplication tables, telephone numbers, and math formulas are better learned by rote. Ideas are best learned by understanding. The more ways you have to think about an idea, the more meaning it will have; the more meaningful the learning, the better you can remember it. Pay attention to similarities in ideas and concepts, and then try to understand how they fit in with things you already know. Never be satisfied with anything less than a completely clear understanding of what you are reading. If you are not able to follow the thought, go back to the place where you first got confused and try again. Which of the following is NOT helpful for your understanding? | [
"Thinking about an idea in different ways.",

mmlu_train_46952 | Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people's depression, physical activity, and life satisfaction. "No one will argue that an older person is better off being more active, challenged, or stimulated ," Edwards points out. "The problem is how we promote (......) that, especially for those without friends or help. A robotic dog could be a solution." In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner. "I talk to him all the time, and he responds to my voice," says a seventy-year-old lady. "When I'm watching TV, he'll stay in my arms until he wants down. He has a mind of his own." The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns. "At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry, " Beck says. "But it's amazing how quickly we have given up that belief." "Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters' blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people's minds. " In the research, the old people are asked to _ . | [

According to the Sleep Council, "junk sleep" could compete with eating unhealthy junk food as a main worrying lifestyle for parents of teenage children. Among the l, 000 students aged 12 t0 16 who were tested in the survey, 30 percent just slept for 4 to 7 hours a day. Almost a quarter said they fell asleep, more than once a week, while watching TV, listening to music or using other electronic gadgets. "This is a quite worrying trend ", said Dr Chris Idzikowski of the Edinburgh Sleep Centre. "What we are seeing is the appearance of terrible junk sleep - sleep that is of neither the length nor the quality it should be." Nearly each of the teenagers had a phone, music system or TV in his or her bedroom, with around two-thirds owning all three. Almost one in five of the teenage boys said the quality of their sleep had been influenced by leaving their TVs or computers on. The survey also found that 40 percent of youngsters felt tired each day, with girls aged 15 to 16 feeling the worst. "Teenagers need to wake up to the fact that to perform well. They need to do something about their sleep. I'm shocked that so few teenagers have noticed ," said Idzikowski.

A new iPhone application that takes a picture of the meal with the phone and gives a calorie read-out almost at once, may help. The MealSnap was developed by DailyBurn, a fitness social network that has created several other fitness and diet-related iPhone applications. Within minutes of taking a picture of a meal and matching it to the given information of some 500, 000 kinds of food, the application sends users a warning with a range of calories for the meal that was photographed. To start with, we sent it something simple--a Braeburn apple. A couple of minutes later the application replied that it was between 64 and 96 calories. Andy Smith, chief director at DailyBurn, said: "The database can also quickly help recognize the food, how many calories there are, proteins, fat, carbs, vitamins, whatever you may want to know." Mr Smith added that it will take some time to complete calorie counting but the application makes it easier to record the calories in food. That is why it is so popular among those who are trying hard to lose weight. "The pure act of recording something can cause a psychological change that can help people on their health and fitness plan. Just the simple fact of recording it makes me more understand what I'm eating," he said. In addition, MealSnap can serve as a food diary, allowing users to keep a readable record of the meals they have eaten. Mr Smith said:"It's like a food journal, but easier. All you do is take the picture." MealSnap is available on the iTunes store for PS1.79, or $2,99 in the US. Why did DailyBurn invent the MealSnap according to the passage? | [

mmlu_train_63755 | Bottled water has become the choice for people who are healthy and thirsty. Bottled water is all over the world. But some say the planet's health, and people's health may be suffering from it. The idea that bottled water is safer for humans may not be true. The Natural Resources Defense Council of America said, "There is no promise that because water comes out of a bottle, it is cleaner or safer than water from the tap." Another New York City-based action group added that some bottled water is "really just tap water in a bottle--sometimes more clean, sometimes not." It is not proven that bottled water is better than tap water. Nick Reeves from the Chartered Institution of Water and Environmental Management said, "The high mineral content of some bottled water makes them not good for feeding babies and young children." Also, most bottled water doesn't have fluoride , which can make teeth stronger. Kids are drinking more bottled water and less fluoridated tap water, and some say that's behind the recent rise in bad teeth. Storing is another problem. Placed near heat, the plastic bottles can produce bad chemicals into the water. According to the Environmental Protection Agency, some 2.7 million tons of plastic are used worldwide to bottle water each year. The plastic can take between 400 and 1,000 years to break down. In terms of energy use, plastic bottles are also not cheap. One report said that if water and soft drink bottlers had used 10 percent recycled materials in their plastic bottles, they would have saved about 72 million gallons of gas. So, if you are worried about the effect of bottled water on the Earth, you can take the following steps. *Drink from your tap. Unless your government warns against this, it should be fine. *Get a container . Carry your tap water in a steel or a lined drinking container, and clean it between uses. *Keep it cool. Don't drink from a bottle that has been sitting in the sun, don't store it near chemicals, and don't reuse plastic bottles. *Choose glass containers over plastic if possible. When finished, recycle!

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.

mmlu_train_30748 | The time of year a baby is born can shape what profession they will embark on in later life, a new study has suggested. Being born in a certain month appears to indicate the statistical likelihood of what job a person will end up with, the study by the Office for National Statistics found. Researchers have uncovered that the month in which babies are born could also affect everything from intelligence to length of life. A child born December is more likely to become a dentist while someone whose birthday falls in January will tend to a debt collector, they found. A February birth appears to increase the chances of being an artist while March babies appear to go on to become pilots. Meanwhile, April and May are said to have a fairly even spread of professions, births in the summer months mean a much lower chance of becoming a high-earning football player, doctor or dentist. The study was derived by researchers who analyzed the birth months of people in 19 separate occupations using information from the last census, the Daily Mail reported. Although these trends may be difficult to explain, correlations between birth months and specific health problems have a scientific basis. Spring babies are at greater risks of illnesses including schizophrenia, Alzheimer's disease, asthma and autism. They may also be less clever than classmates born in other parts of the year.

mmlu_train_54002 | Can people change their skin color1 without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color1. The gene comes in two versions, one of which is found in 99 percent of Europeans. The other is found in 93 to 100 percent of Africans, researchers at Pennsylvania State University report in the latest issue of science. Scientists have changed the color1 of a dark-striped zebrafish to uniform gold by inserting a version of the pigment gene into a young fish. As with humans, zebrafish skin color1 is determined by pigment cells, which contain melanin . The number, size and darkness of melanin per pigment cell determine skin color1. It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation in the gene for melanin production. This results in less pigmented skin. However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes. Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun , which can cause skin cancer. But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng. "Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color1," said Cheng. The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color1 without damaging it like chemical treatment did on Michael Jackson. ks5u It can be inferred from the passage that _ . | [

When someone is very sick, the doctor has to fly to the person's home. His plane lands on a flat piece of ground near the person's house. Sometimes the doctor has to take the patient to hospital. Flying doctors take about 8,600 people to hospital each year. However, most of the time the person isn't very sick, and the doctor doesn't have to visit. He can give advice on the radio from the office at the flying doctor center. He can tell the patient to use some medicine from a special medicine chest .

Despite its bad name, and the fact that the species was alive during recorded human history, little is actually known about how this animal lived, looked, and behaved. A new study of the only known complete skeleton from a single bird takes advantage of modern 3-D laser scanning technology to open a new window into the life of this famous extinct bird. The study was presented at the 74th Annual Meeting of the Society of Vertebrate Paleontology in Estrel, Berlin. Leon Claessens, Associate Professor at the College of the Holy Cross, and lead researcher on the study said that, "the 3-D laser surface scans we made of the fragile dodo skeletons enable us to reconstruct how the dodo walked, moved and lived to a level of detail that has never been possible before. There are so many outstanding questions about the dodo bird that we can answer with this new knowledge." A complete dodo skeleton, found by an amateur collector and barber, Etienne Thirioux, on the island of Mauritius between 1899 and 1917, has remained unstudied, even though it is the only complete dodo skeleton from a single individual bird known to exist. All other skeletons are incomplete combinations, meaning that they are gathered from more than one individual. In addition, Thirioux constructed a second, partially combined skeleton, which contains many bones that also belong to a single bird. "Being able to examine the skeleton of a single, individual dodo, which is not made up from as many individual birds as there are bones, as is the case in all those other combined skeletons, truly allows us to appreciate the way the dodo looked and see how tall or fat it really was," said Juilan Hume, of the Natural History Museum UK, a co-author on the study. The scans were performed on site in Durban, South Africa, and allow examination of the biology of this mysterious extinct bird in detail for the first time. Using the newest digital tools and techniques, the scans provide an insight into how the flightless dodo may have developed its giant size, and how it walked and lived in its forest home. According to Kenneth Rijsdijk, a biologist from University of Amsterdam, "the skull of the dodo is so large and its mouth so strong that it is easy to understand that the earliest naturalists thought it was related to sharks and other birds of prey , rather than the pigeon family."

The new study, conducted by the National Cancer Institute (NCI), has been published and suggests that coffee does not have a harmful effect on your health. Researchers suggest, based on data examined, older adults who drink a lot of coffee, have a lower risk of death when compared to their non-drinking coffee peers. The team of researchers conducting the study analyzed data on 400,000 U. S. men and women,aged 50 to 71 years; the individuals had participated in the NIH-AARP Diet and Health Study. This study started in 1995-1996 and was tracked until the day a participant passed away, or Dec. 31, 2008. According to a press release on the report, researchers shared that coffee drinkers are "less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the relationship was not seen for cancer." Results indicated participants that drank three or more cups of coffee a day reduced their risk of death by 10 percent. Based on the findings that both caffeinated and non-caffeinated coffee found similar results, researchers are thinking caffeine is not the protective ingredient , although which ingredient in coffee might be, they are not sure. Researchers indicate that despite these observational findings, they caution it is not clear whether or not drinking coffee actually extends life expectancy. "Coffee is one of the most widely drunk drinks in America, but the relationship between coffee consumption and risk of death has been unclear. We found coffee consumption to be associated with lower risk of death overall, and of death from a number of different causes," said Neal Freedman, Ph. D., Division of Cancer Epidemiology and Genetics, NCI. "Although we cannot infer a relationship between coffee drinking and lower risk of death, we believe these results do provide some comfort that coffee drinking does not adversely affect health," Freedman said.

At Beth Israel each patient is assigned to a primary nurse who visits at length with the patient and constructs a full-scale health account that covers everything from his medical history to his emotional state. Then she writes a care plan centered on the patient's illness but which also includes everything else that is necessary. The primary nurse stays with the patient through his hospitalization. keeping track with his progress and seeking further advice from his doctor. If a patient at Beth Israel is not responding to treatment. it is not uncommon for his nurse to propose another approach to his doctor. What the doctor at Beth Israel has in the primary nurse is a true colleague. Nursing at Beth Israel also involves a decentralized nursing administration; every unit is a self-contained organization.

mmlu_train_47969 | Communications technologies are far from equal when it comes to conveying the truth.The first study to compare honesty across a range of communication media has found that people are twice as likely to tell lies in phone conversations as they are in emails.The fact that emails are automatically recorded--and can come back to puzzle you---appears to be the key to the finding. Jeff Hancock of Cornell University in Ithaca, New York, asked 30 students to keep a communications diary for a week.In it they noted the number of conversations or email exchanges they had lasting more than 10 minutes, and confessed to how many lies they told.Hancock then worked out the number of lies per conversation for each medium.He found that lies made up 14 per cent of emails, 21 percent of instant messages, 27 per cent of face-to-face interactions and an astonishing 37 percent of phone calls. His results to be presented at the conference on human-computer interaction in Vienna, Austria, in April, have surprised psychologists.Some expected emailers to be the biggest liars, reasoning that because deception makes people uncomfortable, the indirect contact of emailing would make it easier to lie.Others expected people to lie more in face-to-face exchanges because we are most practiced at that form of communication. But Hancock says it is also crucial whether a conversation is being recorded and could be reread, and whether it occurs in real time.People appear to be afraid to lie when they know the communication could later be used to hold them to account, he says.This is why fewer lies appear in email than on the phone. People are also more likely to lie in real time---in an instant message or phone call, say---than if they have time to think of a response, says Hancock.He found many lies are spontaneous responses to an unexpected demand, such as: "Do you like my dress?" Hancock hopes his research will help companies work out the best ways for their employees to communicate.For instance, the phone might be the best medium for sales where employees are encouraged to stretch the truth.But, given his result, work assessment where honesty is a priority, might be best done using email. According to the passage, why are people more likely to tell the truth through certain media of communication? | [

mmlu_train_22020 | Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness usable wind energy produced by man-made technologies. One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can be transformed into electricity. According to Pradhan's proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts of electricity could be harvested each day. Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device called T-Box that harnesses wind energy from speeding trains. T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers , which does not disturb the normal train operating at all. According to Yanko, around 150 T-Boxes can be fitted along a 1,000-meter railway track. A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box's design won a silver medal in last year's Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei, Taiwan Province. Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn't taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance of the device. We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.

mmlu_train_20388 | Animal moms are great moms. You might be surprised at some of these moms. Octopuses The mother octopus lays about 50,000 eggs. For about 300 days, she stays with the eggs, cleans them and protects them. She does not leave to feed. However, this animal mom dies as soon as the eggs are hatched . Crocodiles A crocodile mother puts a lot of time and effort into raising her babies. She starts by building a nest , which she guards for over two months! When the eggs are ready to hatch, the young crocs call out to their mother, who digs them out and helps them hatch. She then carries them in her mouth down to the water, where she will guard them for several more weeks or months until they learn to hunt on their own. Bats Bats become moms by hanging head up in a cave, giving birth. Catching the youngster before it can fall to the ground below, she puts it in a pouch . Bat moms may carry babies with them when feeding for the first few days. As the little bats get bigger and heavier, moms help them hang on the wall of their caves and return often to feed them. It continues for about three weeks, until the babies are grown up and able to fly on their own. Koalas The animal mom gives birth after a pregnancy of only 35 days. The hairless baby climbs into its mother's pouch and lives there for another five months. When the little koala is between five and eight months old, it leaves the pouch for short periods of time but returns for safety. Once it is too big to return to the pouch, it will climb onto its mother's back and ride there until it is about 12 months old. A bat mom _ . | [
