mmlu_train_90004 | When kids at Archisha Singh's school in Loudoun County have a birthday, no parents buy them birthday cakes. Some schools are worried that children might become fat or eat unhealthy food, so they have banned cupcakes altogether. What do kids do? Birthday kids can donate a book. The headmaster of their school will then read it to their class. The headmaster also hands out birthday certificates , special pencils, and makes sure the kids' names are read out in the school's morning news. Parents can send stickers , pencils and other things to students. None of the things can be food. If a child donates jump ropes or other sports equipment, that child may get his or her name on a certificate. It will then be displayed at school. Archisha really misses cupcakes, especially those her mother used to make for her kindergarten class, but her school's way is fun, too. "I like both ways," she said. The headmaster says it's important that the school should be not only teaching, but offering healthy choices to kids. "There is a better life without cupcakes. If you eat a cupcake, then it's gone in two seconds, but a book lasts a lifetime. The sports equipment lasts, and the kids can use it day after day." The headmaster thinks the school should _ . | [

mmlu_train_15194 | The US company iRobot made a new kind of sub-marine , called the Seaglider, last week. The robotic submarine was developed by researchers at the University of Washington. It is about 1.8 meters long and weighs about 52 kilograms. It moves through water at a speed of up to 20-25 kilometers a day and can stay at sea for up to six months before needing a battery recharged. This special character results from its special propulsion system . Unlike a traditional submarine, the Seaglider does not have a propeller . It has an air tank that is emptied and filled to adjust depth, as well as a pair of wings that help to guide and lead the submarine. A traditional submarine, on the other hand, "puts water inside tanks to make it heavier, or it will expel the water to make it lighter," explained Frederick, a professor at the University of Washington. Each time the Seaglider comes to the surface, it sends the data which it collects to its controllers by satellite. Operators can also send the submarine new information. For example, they can change its course in their office through giving the computer orders. Seagliders are already being used for scientific research, such as environmental studies. iRobot also hopes to sell the submarine to the military . At $100,000 each, the Seaglider is a cheap way to keep an eye on the ocean. "These things can go out there and monitor large areas of ocean because they're very persistent. They can go for thousands of miles on their own. At the same time, you can tell them to stay in one place and they can circle," says Helen Greiner, chairwoman of iRobot. "This is science fiction stuff in many ways, but it's really out there and working." Nowadays, the Seaglider is being used only _ . | [

mmlu_train_79063 | Spiders are not insects as many people believe. They belong to a class of animals called arachnids . Spiders have eight eyes, four pairs of legs, and can grow a new leg if they lose one. A spider's body is divided into two sections: the abdomen and the thorax .The legs, eyes, and mouthparts are in the thorax section. Most spiders have poison glands and sharp teeth. They use their sharp teeth to force poison into the insects they catch for food. This poison can make an insect lose the ability to move, and the helpless insect is then _ by the spider. Spiders usually have silk glands under their abdomen. They produce a liquid that is thicker than water from their glands. When the liquid comes into the air, it dries into silk. Many spiders use this silk to form webs to catch insects and to make cocoons that protect their eggs. This amazing silk is also used to create lines that spiders hang onto as they travel to new areas. Spiders live in almost everywhere on earth. The only places where there are no spiders are the coldest places, the highest mountains and the seas. According to the passage, which of the following is WRONG? | [

mmlu_train_39167 | Researchers designing the 'classroom of the future' have found that multi-touch, multi-user desks can improve skills in mathematics. New results from a 3-year project working with over 400 pupils, mostly 8-10 year olds, show that cooperation learning increases both fluency and flexibility in maths.It also shows that using an interactive 'smart' desk can have Benefits over doing mathematics on paper. Using multi-touch desks in the new classroom, the children were able to work together in new ways to solve problems using inventive solutions.Seeing what your friends are doing, and being able to fully participate in group activities, offers new ways of working in class, the researchers say.The 'Star Trek classroom' could also help learning and teaching in other subjects. Lead researcher, Professor Liz Burd, said: "Our aim was to encourage far higher levels Of active student engagement, where knowledge is obtained by sharing, problem-solving and creating, rather than by passive listening.This classroom enables both active engagement and equal access." "We found our tables encouraged students to cooperate more effectively.We were delighted to observe groups of students improving their understanding of mathematical concepts.Such cooperation just did not happen when students used paper-based approaches." The teacher plays a key role in the classroom and can send tasks to different tables to individuals and groups.The teacher can also send one group's answers on to the next group to work on and add to, or to the board for a class discussion.A live feedback of the desks goes directly to the teacher who can come quickly to help an individual while allowing the group work to continue. Such a classroom may be some way off being a regular feature of schools across the.World due to the costs in setting it up.However, in just 3 years the project team have noted major improvements in the technology, and a reduction in costs.

mmlu_train_25735 | The making of glass is a very old industry---at least 4,500 years old. Glass has many extraordinary qualities and it is often being used in new ways. One of the most interesting new uses for glass is in telephone communication. Scientists have developed glass fibers as thin as human hair which are designed to carry light signal. When the light reaches the other end,it is first changed into electrical signals , which are in turn changed into sound messages. Called lightwave communication, the new system was used successfully in an experiment in Chicago in 1977. During the experiment, two glass fibers were able to carry 672 conversations at the same time. The lightwave cable , containing 144 glass fibers, is able to carry 50,000 conversations at the same time. The lightwave communication system has two important advantages. First, the glass fiber cables are smaller and weigh less than copper cables. Second, they cost less. Perhaps it can be said that telephone communication has entered the age of light.

That is the Scholastic Aptitude Test, or SAT, an American test for students who intend to apply for college admission. Chen Huanlu, aged 18, from Shandong Province took part in the SAT subject tests (SAT 2) in Hong Kong on June 2. She has also been scheduled to take the SAT reasoning test (SAT 1) in October. "I hope to study environmental engineering at an American university, where I may have more opportunities to get cutting-edge knowledge in this area," said Chen. However, not all SAT test takers want to apply to American universities. "I wanted to see how I would do when faced with plenty of stress and also to evaluate my scholastic level by an American standard. The SATs made my school life more diverse," said Senior 2 student Zhou Yuxiang from Sichuan Province. Zhou, aged 17, a top student in his school, was inspired by some of his friends. They have taken this test and been admitted to American universities, including Harvard and Yale. Last winter vacation he took a 20-day SAT course at Chengdu New Oriental School. "As I prepared for the test in the following months, I was forced to balance my everyday schedule better. Fortunately I was optimistic enough to have undergone the most difficult time," he said. In May and June, Zhou flew alone to Hong Kong to sit for the SAT1 and SAT2. "They are both the standards which have been set for us to reach. What we should do more sensibly is to try harder to prepare for them. Survival of the fittest is true both in America and in China. That is something I have learnt beyond the SAT itself," he said.

For small pieces of weather--to a global forecaster, small can mean thunderstorms and blizzards --any prediction becomes worse rapidly. Errors and uncertainties increase, from dust devils and storms up to continent-size eddies that only satellites can see. The modern weather models work with net-like points sixty miles apart, and even so, some starting data have to be guessed, since ground stations and satellites cannot see everywhere. But suppose the earth could be covered with sensors placed one foot apart, rising at one-foot intervals all the way to the top of the atmosphere. Suppose every sensor gives perfectly accurate readings of temperature, pressure, humidity , and any other data a weatherman would want. Exactly at noon a powerful computer takes all the data and calculates what will happen at each point at 12.01, then 12.02, then 12.03... the computer will still be unable to predict whether Princeton will have sun or rain one month away. At noon the spaces between the sensors will hide fluctuations that the computer will not know about. By 12.01, those fluctuations will already have created small errors one foot away.

Finally they found out the truth. When the birds were flying, they couldn't see into the rooms. All they saw was the reflection of the garden. They thought that they were flying into trees because they saw trees reflected by the window. "Something has to be done to save the birds." the parents decided.

For example, one of my classmates, Mike, doesn't have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others' teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of them. Smiling can help you to feel more confidence and make people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh.

mmlu_train_45223 | Cellphones: is there a cancer link? Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and wi-fi could be responsible for a range of illnesses, from rashes to brain tumors. Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there's a greater than 95 percent chance that power lines can cause childhood leukemia . Also there's a greater than 90 percent chance that cellphones can cause brain tumors. "It's apparent now that there's a real risk," said Carpenter. But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. "I don't support warning labels for cellphones," said Linet. "We don't have the evidence that there's much danger." Studies so far suggest a weak connection between EMFs and illness -- so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been _ for several years. It's funded in part by the European Union, in part by a cellphone industry group. The final report should come out later this year, but data so far don't suggest a strong link between cellphone use and cancer risk.

mmlu_train_54223 | When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky. "What excited me most was whether there were planets in other solar systems where life might exist," he says. "I decided to try to find planets orbiting other stars like our Sun." And he did. "My fellow researcher, Paul Butler, and I found our first planet in 1995," Dr. Marcy says. "We worked for ten years without finding anything! _ and our patience paid off." Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first "family" of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri. At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun. Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter. "Because it's so big, Jupiter pulls comets and asteroids , or they all come and hit the Earth." Dr. Marcy explains. "Without Jupiter , life on Earth would likely have been destroyed." A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life.

mmlu_train_67509 | Millions of stars are travelling about in space. A few form groups which travel together, but most of them travel alone. And they travel through a universe which is so large that one star seldom comes near to another. For the most important part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbour. From this it is easy to understand why a star seldom finds another anywhere near it. We believe, however, that some two thousand million years ago, another star wandering through space, happened to come near our sun just as the sun and the moon raised its tides on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; A large tidal wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and thrown off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets. In the article, the writer mainly wants to tell us _ . | [

mmlu_train_52156 | Reading new peaks of popularity in North America is Iceberg Water which is harvested from icebergs off the coast of Newfoundland, Canada. Arthur von Wiesenberger, who carries the title Water Master, is one of the few water critics in North America. As a boy, he spent time in the larger cities of Italy, France and Switzerland, Where bottled water is consumed daily. Even then, he kept a water journal, noting the brands he liked best. "My dog could tell the difference between bottled and tap water." He says. But is plain tap water all that bad? Not at all. In fact, New York's municipal water for more than a century was called the champagne of tap water and until recently considered among the best in the world in terms of both taste and purity. Similarly, a magazine in England found that tap water from the Thames River tasted better than several leading brands of bottled water that were 400 times more expensive. Nevertheless, soft-drink companies view bottled water as the next battle-ground for market share-this despite the fact that over 25 percent of bottled water comes from tap water: PepsiCo's Aquafina and Coca-Cola's Dasani are both purified tap water rather than spring water. As diners thirst for leading brands, bottlers and restaurateurs salivate over the profits. A restaurant's typical mark-up on wine is 100 to 150 percent, whereas on bottled water it's often 300 to 500 percent. But since water is much cheaper than wine, and many of the fancier brands aren't available in stores, most dines don't notice or care. As a result, some restaurants are turning up the pressure to sell bottled water. According to an article in The Street Journal, some of the more shameless tactics include placing attractive bottles on the table for a visual sell, listing brands on the menu without prices, and pouring bottled water without even asking the dinners if they want it. Regardless of how it's sold, the popularity of bottled water taps into our desire for better health, our wish to appear cultivated, and even a longing for lost purity. Why are some restaurants turning up the pressure to sell bottled water? | [

mmlu_train_16481 | The Italian island of Sardinia recently lost its oldest citizen. Family members say Antonio Todde died in his sleep early this month. Mr. Todde was 112 years old. It was less than three weeks away from his 113thbirthday. Record-keeping experts say he was the world's oldest man. His long life and that of other very old Sardinians are the subjects of a scientific project called Akea. Luca Deiana of Sassari University is directing the study. He says the name Akea comes from a traditional greeting on Sardinia. It means"health and life for 100 years". Professor Deiana and his team started to collect information for the study in 1997. They identified more than 220 Sardinians who were centenarians--100years old or older. His team required three documents to confirm a person's age. They were a government birth record, a church record and a statement by a close family member. The Akea study has produced two major findings. The first is Sardinia's extremely high number of centenarians. The island had about 135 centenarians for every one million people. In other Western countries, the average is about seventy five centenarians for every one million people. The second major finding is an unusual rate of female to male centenarians. Sardinia has two women centenarians for every male centenarian. In central Sardinia there are equal numbers of female and male centenarians. Studies in other parts of the world have shown a much higher percentage of female centenarians. The Akea study collected information about the health and diet of about 140 of the centenarians. About ninety percent of those in the study agreed to provide blood for scientific testing. The study team hope to identify genetic material in the blood that can be linked to successful aging. Study leaders say there is no single reason why people on Sardinia live so long. They believe the answer is a combination of genetic and environmental conditions. Why do Sardinians live so long according to the study? | [

mmlu_train_13886 | Australian cities can keep their native wildlife -- but only if they can kick their habit of urban sprawl . That's the finding of a new study by leading Australian environmental researchers Jessica Sushinsky, Professor Hugh Possingham and Dr Richard Fuller of The University of Queensland. "While urban development usually reduces the number of birds in a city, building more compact cities and avoiding urban sprawl can slow these reductions greatly," says lead author Jessica Sushinsky. "Compact housing development leaves birds' homes untouched, leading to fewer losses of birds." The researchers surveyed native and wild birds in Brisbane's urban areas, including living and industrial areas, public parks and gardens, major roadways and airports. They then used statistical modeling to find out what will happen to the birds as the city grows. The first setting was compact growth -- where multiple homes are built on land that previously had only one house. The second setting was sprawling growth -- a familiar pattern where homes are built here and there beyond the city's current boundaries. The team's forecasts showed that a much greater diversity of species was lost over 20 years in the sprawling setting compared to the more compact setting. "Urban sprawl resulted in the disappearance of many urban-sensitive birds -- birds that only live in areas where there is native vegetation , such as parklands and woodlands," Ms Sushinsky says. "On the other hand, we found the city with the compact development attracted more birds because it kept more of its parks and green areas." Now the Queensland Government has adopted the more compact urban growth strategy, which, Dr Richard Fuller says, is good news for Australia's native birds. These birds are environmental specialists -- they need a particular environment to do well. "While compact development means smaller backyards, it can also make our entire cities more biodiverse," according to Dr Fuller. "The study shows that we should hold on to our green spaces instead of clearing them for sprawling development." This is the first time science has modeled the effects of different urban growth strategies on birds, the researchers say. "Statistical models like these are important because they help us to understand the ecological consequences of a particular decision," says Dr Fuller. What can we learn about the study from the passage? | [

mmlu_train_29349 | 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. Which of the following is helpful to have quality sleep at night? | [

mmlu_train_7677 | The effects of air pollution on natural conditions have been a disturbing problem for many years. Some scientists hold the view that the air inside houses may be more dangerous than the air outside. It may even be one hundred times worse. Most scientists agree that every modern house has some kind of indoor pollution, which can cause a person to feel tired, to suffer eye pain, headache and other problems. Believe it or not, some pollutants can cause breathing diseases of blood and even cancer. What made us feel relieved is that there's growing concern about the problem now. It is true that when builders began constructing houses and offices they did not want to waste energy. they built buildings that prevented or limited the flow of air between inside and outside. For the same purpose, man-made building materials were employed to build houses, which are now known to let out some harmful gases. Facing the serious challenge, scientists have been searching for a way to handle the problem. To everyone's delight, they discovered a natural pollution control system for building--green plants, though they do not really know how plants control air pollution. Scientists suppose that a plant's leaves absorb or take in the pollutants and in exchange gives out oxygen through its leaves and tiny organizations on its roots. Therefore they recommend that all buildings should have one large plant or several small plants inside for every nine square meters of space. Because studies indicate that different plants absorb different chemicals, the most effective way to clean the air is to use different kinds of plants. In conclusion, having green plants inside your house can make it a prettier and healthier place. Why not try? Which of the following statements is TRUR? | [
"Outside air pollution is more harmful than the air inside.",

"Indoor air pollution may cause diseases including cancer.",

We have to remember that we get 2 days' holiday at Easter, 3 at Christmas and 1 at the New Year. There are also 4 Bank holidays. Take those 10 days away and we have 32 days for work. But then we have one and a half hours' lunch every day, and half an hour's coffee break. That comes to 30 days a year. This means that we have only a few days left for work every year! According to the passage, we know that we don't have _ time to work every year. | [

mmlu_train_36239 | Travel is exciting and summer is a busy period for holiday travel. Many people will travel great distances in airplanes, cars or other vehicles. Experts say people should know about other health problems that can strike when traveling by air. One of these is a condition called hypoxia . It results from a lack of oxygen to the brain. Experts say the body begins losing oxygen minutes after an airplane leaves the ground. The air pressure in a plane during flight is lower than at sea level. This makes it more difficult for the body to effectively use the same amount of oxygen as it would on the ground. Fewer oxygen molecules cross the tissues in the lungs and reach the bloodstream. The result is a five to twenty percent drop in the amount of oxygen in the blood. This reduces the amount of oxygen that reaches the organs of the body. One effect of this lack of oxygen to the brain is a headache. When this happens, the heart attempts to _ by beating harder and faster. This can make the traveler feel tired. These signs of hypoxia are not dangerous in a healthy person. But a drop in oxygen level can cause a health emergency in people with heart or lung problems. They might lose consciousness or even suffer a heart attack. Experts say that smoking cigarettes and drinking alcoholic liquids also reduce the body's ability to use oxygen. So they suggest that people not drink alcohol or smoke cigarettes either before or during a flight. They also say persons with heart or lung problems should seek advice from their doctors before flying. According to the passage, what leads to hypoxia? | [

But that Francisco Lopez and Ruby Nostrant track what climate change is doing to five different plants in Tucson, Arizona and they are only in the second grade. "We are collecting data because the weather is changing and the plants are blooming," Ruby explained. Scores of other students at Borton Primary Magnet School and Sunnyside High School in Tucson are heading outdoors to be part of a new scientific push to figure out how the biological timing of the earth is changing. It's a research project that the average person, even a kindergartner, can join in. The National Phenology Network is calling on volunteers to help track early spring blooms and eventually changes in animals caused by global warming. It's called Project Budburst. When it was first open to the public last year, thousands of people participated in 26 states. "All people can contribute to it by tracking the timing of flowering events or leaf-out events for plants and animals in their backyard," said Phenology Network director Jake Weltzin. He calls the volunteers "citizen-scientists." The idea is that tracking flowers blooming--especially lilacs ; which everyday people have helped track for decades--is fairly simple. The Website http://www.Windows.ucar.edu/ citizen _ science/budburst/index.html gives directions on what to look for in different parts of the country. University of Maryland professor David Inouye said it's so easy to figure out what's blooming that a lack of special knowledge isn't a problem. University of Arizona ecology graduate student Lisa Benton coordinated the Tucson high school students as they looked at plants five minutes from their high school. Each student has specific guidelines and she's been happy so far with the data she is getting. For his part, second-grader Francisco said he had fun helping out. "I like going out in the desert," he said. "I want to be an Einstein." Who is primary school student joining in the Project Budburst? | [

mmlu_train_8419 | You are what you eat and fats are a main food for Asia's fast-food generation. Dr.Chwang, director of the Department of Food Nutrition, says children are consuming more meat and soft drinks. That is a thorough departure from the traditional diet of vegetables and rice and little meat." They like big pieces of fried meat with a soft drink. So although they may eat the same volume of food, their calorie intake has increased. Now that 40 to 45 percent of their calories come from fat," says Chwang. Although on the whole Asians tend to thinness, culture--namely Asians' hospitality--is a reason for the fatness of today's generation, according to Chwang. "Asian people love food," she says." Eating and drinking are important social and family functions." In the past, however, big meals were only hosted on special occasions, as people were more careful with money. In today's climate of wealth and remarkable consumption,10-course meals are no longer reserved for significant occasions. "In the past, people had four or more children--now, they have one or two, so they tend to spoil them," says Chwang. "The earliest way is to give them quality food. Parents think feeding them well is showing their love. They feel bad when their children look thin." When describing the physical condition of most overweight Asian children, Chwang says: "there is a clear relation between fatness and indoor play. Children get fat because they don't move, and eventually, they don't want to move because they are fat." Thanks to technology, a growing army of children prefer video games to old outdoor sports. "What do children do when watching TV or sitting in front of the computer playing video games? They eat chocolate and drink Coke," says Chwang. The purpose of this article is to _ . | [

mmlu_train_35951 | The World Health Organization recently reported that the number of cases of tuberculosis(TB) has been _ since 2006 . Also, fewer people are dying from TB. But a study by researchers at the University of California, San Francisco, says smoking could threaten this progress. Nearly twenty percent of all people use tobacco, and millions of non-smokers get sick from breathing the smoke. The new study predicts that smoking will produce an additional thirty-four million TB deaths by 2024. Efforts to control the spread of TB have mainly focused on finding and treating infections. Fewer efforts have been made to understand the causes. Dr Anthony Fauci is the director of the United States National Institute of Allergy and Infectious diseases. He said, "Despite our control efforts, we still have more than a million people each year dying from TB and millions of people getting infected; we realize it's still a very important problem. So we have to do the practical thing and we have to do the fundamental research things at the same time. " Smoking does not cause TB; bacteria cause the infection. But the study says smoking affects the nervous system in a way that makes an inactive case of TB more likely to develop into an active one. Stanton Glantz is the director of the University of California's Centre for Tobacco Control Research and Education and an author of the new study. He says it shows that TB cannot be controlled unless tobacco use is controlled. He said, "It increases the number of people who will get TB by about seven percent." The study is described as the first to identify a direct link between tobacco use and rates of TB infection and death. Professor Glantz says the results should guide those creating health policies and TB control efforts. He said, "If you want to control the infectious disease of TB, you have to control the tobacco industry and the tobacco industry's efforts to increase tobacco use, particularly in developing countries where TB is a big problem." What would Dr Anthony Fauci probably agree with? | [

Cakes and sandwiches are brought in by footmen, yet you never see the Queen touch a thing. She simply sits beside a big silver plate, pouring cups of tea for everyone and carefully avoiding the cakes. At cocktail parties the Queen moves from group to group, chatting informally, and manages to make one glass of diet drink to last an entire evening. Tours abroad are difficult because hosts seem to believe the warmth of their welcome must be shown with wonderful state banquets . But the Queen has perfected the art of appearing to enjoy her meal without actually eating much. During one visit to the Pacific islands ofprefix = st1 /Tonga, a specially-prepared dinner was arranged in a hut made of wood and bamboo leaves. Deep holes were dug in the ground, filled with hot stones and baby pigs, and the pigs were slowly baked over several days. The Queen looked uneasily at her plate when she discovered a whole roast pig was her serving. Then she became uneasy when a turkey, some meat, bananas and an apple were also carried in for each guest. So she depended on her old favorite trick of talking with her host., King Tupou IV, carrying on a warm conversation. At the same time she pushed her food around her plate and only ate a piece of turkey and some fruit. Reporters traveling with her have noted that the Queen will sometimes seem so carried away by a foreign leader's political chat that she simply never has time to finish a meal before it is time to get up and make her speech. She will lift her fork to swallow a mouthful, then put it down again to make another point, leaving almost all of her meal untouched. What probably is the Queen's art of acting at state dinners? | [

But this 19-year-old Swede is anything but ordinary, from the computer in his parents' home he helps the US Federal Bureau of Investigation (FBI) find out the world's most wanted cyber criminals . Jonathan first made headlines when he and another Swede, Fredrik Bjoerck, found out the maker of the "Melissa" virus in March 1999. He came to the aid of the FBI again on May 7, finding out the suspected sender of the dangerous "I LOVE YOU" virus. The suspect was caught in Manila on May 8. Jonathan's special skills are in hot demand as officials around the world express alarm at the "virtual" crimewave. In between studying for final exams, hanging out with friends and refereeing his younger brother's football matches, the quiet, gentle teenager also gives lessons on e-security to large companies. He reads a lot and exchanges information with other computer experts to know much about the latest tricks of the hacker trade. Many companies have already tried to employ him, but he is not interested at the moment. Instead, he plans to begin law school in the autumn at Sweden's Uppsala University and start up his own e-security company. Although he works with the FBI now, his family insists he's just "a regular kid". "Jonathan is a great kid, he has his friends and he does a lot more than just play with the computer," his little sister Tessa said, adding that he helps the FBI because "he likes to help", not because he's looking for fame and recognition. When the world was hit by the "Love Bug" virus, Jonathan was too busy preparing a speech on e-security to look into the problem. "Finally on May 7, I had some free time, so I began looking." Within a few hours, he had found the suspect and e-mailed his method and results to the FBI. He said his work on the "Melissa" virus, which took three weeks to solve, was a big help in finding the suspect so quickly. "This time I knew exactly where to start, I knew what to disregard and what to look at." What do we know about Jonathan? | [

mmlu_train_48730 | The physical memory dump error is a big problem that affects even the most advanced computer systems.Although it's quite a rare error, it's one of the most stopping what you're doing and restarting your computer--making you lose all your unsaved data.This is a big problem, but there is actually a very easy way to fix it. There are two reasons why the physical memory dump happens.The first is pretty simple and is to do with the "hardware", and if any of these pieces are not fit for your system, it will cause the physical memory dump.So, if you've recently added any hardware to your PC, then take that out and see if it works. The other reason is your system, the "registry".The registry is a big database that operates in the background of Windows, storing all sorts of settings and information about your PC.The problem with the registry is that since it has so many important files inside, it's constantly got hundreds of files open every time you use your PC.And because there are so many files to open at once, Windows is constantly getting confused, leading it to save many of these files in the wrong way.These files go wrong when saved wrongly, making them difficult for your computer to read.However, if it can't read the files at all, it has no choice but to stop everything it's doing and restart your PC.This is why the physical memory dump error appears so easily--because when a registry file is so wrong that it can't be read, your computer needs to refresh itself immediately. This latter reason for causing the physical memory dump is actually extremely common and the likelihood is that your PC is suffering from it, if you're seeing this error.Luckily, it's also incredibly easy to fix--you just need to use a software tool called a "registry cleaner" to go through the registry and fix all the problems in there. What does a registry cleaner means? | [

mmlu_train_24384 | Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers conclude that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over. According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers' markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal. After a visit to the United States, Mireille Guiliano, author of French Women Don't Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym. In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity - or extreme overweight - among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17% - and is growing. In what way are the French different from Americans according to Dr. Joseph Mercola? | [
