The central government has asked people entering China from the virus-hit countries to report flu-like symptoms to the authorities.In an emergency notice issued on Saturday night, the country's top quality watchdog ordered the Customs to check passengers' temperature, too. A Beijing airport official Li said Customs officers are on a high alert level. "Three temperature detectors are now in operation.We're ready with protection garments and equipment, too.Passengers flying in from Mexico and other A/H1N1 flu-hit countries are being monitored closely," he said. The Ministry of Health, however, said yesterday there was no evidence to suggest that a person would contract the disease by eating pork. Hong Kong, too, has raised its alert level against the flu to "serious".Secretary for Food&Health, Mr.York Chow urged people to avoid visiting places from where A/H1N1 flu cases have been reported, and said the virus would be added to Hong Kong's list of the diseases which have been noticed. The terrible A/ H1N1 flu has been contracted by about 4000 people in Mexico, and most of the killed were aged between 25 and 45. The virus has also infected about 5,000 people in the US.The US Center for Disease Control said this kind of virus is spreading from human to human, raising fears of a global pandemic.

mmlu_train_21530 | Children and teenagers who spend lots of time in front of screens---especially TVs---are easier to get more weight as they grow, according to a new study. The findings agree with the research suggesting all that inactive sitting and always watching advertisements may lead to poor eating habits. Researchers used results from a long-term study of children who took part in the surveys every two years. Children were between ages 9 and 16 when the study started. Out of 4,300 girls in the study, 17 percent were overweight or obese . Twenty-four percent of the 3,500 boys were also above a healthy weight. The surveys included questions about their height and weight as well as how much time they spent watching TV and DVDs and playing computer and video games. From one survey to the next, each one-hour increase in children's daily TV watching was in connection with an increase of about 0.1 points on a body mass index (BMI) , which measures weight in connection with height. There's an increase of about half a pound in weight per extra hour of TV. "The weight of the evidence is so strong that television watching is connected with unhealthy changes in weight among youth," says Jennifer Falbe, who led the study while at the Harvard School of Public Health in Boston. "It's important for parents to know that all the obesity-causing screens really should be limited in their children's lives." Falbe says. "When children watch TV, there are many food advertisements on TV that might lead them to eat a cookie or drink a soft drink." What's more, she says, "they can get into a hibernating state on the sofa, even if children are sitting down while playing a computer game."

mmlu_train_76117 | Generally speaking, American food is not very thick in taste. Salads are much liked and are served all year round. Many Americans are trying to keep down their weight. This is shown in menus offering "low calorie " or "weight watchers" meals. In markets, one can find "No Cal" drinks (meaning without calories) such as cola. Many Americans drink coffee or tea with their meal. If a waiter in an American restaurant asks "Now or later?", what he means is "Do you want coffee with your meal or later?" When eating out in the USA, we can ask for tea, milk, beer, and so on, if we prefer these to coffee. American restaurants cannot serve beer, wine, or liquor unless they are licensed to do so. The main dish in American meals is usually meat, chicken or fish, but more than one of these is hardly served at the same meal. Most Americans eat quickly during the day--that is, breakfast and lunch--unless it is a social, business, or family situation. The evening meal, however, is usually a family time. Racing through daytime meals is part of the "American pace" of life, for working hours are considered important. The nationwide fast-food restaurants are suitable for the ways of American eating. The standard products, of nearly the same price, are served quickly, and taste the same whether bought in New York City or in Los Angeles. McDonald's is a popular restaurant. It offers many choices of hamburgers, French fries and "cokes". These foods are rich in fats, sugar and salt. Often, they are the major meal of the day of many young working people.

mmlu_train_66689 | One of the 10 things that happy families do is to eat dinner together. As growing up, I thought everyone ate dinner as a family. However, now I realized that is not the case. In fact, most families eat dinner together only about four times a week and 10% of families only eat together twice a week. And as children get older and the number of activities they are involved in increases, the meals eaten as a family decrease. Studies show that families who eat dinner together benefits in a variety of ways. Eating together helps families achieve better communication, children do better in school and are better adjusted, and the entire family enjoys better nutrition . Increased Communication Eating dinner together as a family provides opportunities for communication. A "Family Dinner Experiment " conducted by Oprah Winfrey in 1993 challenged five families to eat dinner together every night for a month for at least half an hour. At first the families found it difficult but by the end of the study they wanted to continue eating dinner together. The biggest surprise for the parents was "How much their children treasured the dependence time with their parents at the table." Superior Academic Performance Family meals also help improve school performance. A 1994 survey by Louis Harris and Associates had 2000 seniors take an academic test and answer a list of personal questions. Researchers found that "Students who regularly ate dinner with their families four or more times a week scored better than those who ate family dinners three or fewer times a week. These results crossed racial lines and were a greater indicator than whether the child was in a one or two-parent family." Better Adjusted A study by Drs. Bowden and Zeisz found that "the teens who were best adjusted ate a meal with an adult in their family at an average of 5.4 days a week, compared to 3.3 days for teens who didn't show good adjustment." The well-adjusted teens were "less likely to do drugs or be depressed and were more motivated at school and had better relationships." Dr. Bowen said, "that mealtimes were a sort of 'marker' for other positive family attributes and seemed to play an important role in helping teens deal well with the stresses of adolescence ."

mmlu_train_63176 | University of Maryland student Ben Simon and his friends couldn't stand to see good food thrown out on their campus."We basically noticed that some of the extra food from the dining hall was going to waste at the end of the day.And we met with the dining services and asked them whether it would be okay if instead of throwing out the food we would donate it.And they were on board," he said. So 18 months ago,the students began what they call the Food Recovery Network.Each night,volunteers would show up at a campus dining hall to pick up leftovers and deliver them to area shelters and food banks.So far,they have donated more than 23 000 kilos of food that would otherwise have been thrown out. Nationwide,$165 billion worth of food is wasted each year,according to the National Resources Defense Council.Spokesman Bob Keefe says that is about 40% of the country's entire food production."If we can reduce our waste in this country by 15%,we can feed 25 million hungry Americans.That is a huge benefit.That is what programs like this Food Recovery Network are doing," he said. Christian Life Center is one of the beneficiaries of the students' efforts.Ben Slye,the senior pastor ,said,"It has been just amazing to see these students take their own time,their own vehicles and own gas money and be able to make an effort like this.Each week we are able with this food probably to feed over hundred people." The University of Maryland's Food Recovery Network now has 200 volunteers and the program has expanded to 18 schools across the country."I want to grow 18 chapters to a thousand chapters within five years.And once we get to the Food Recovery Nation being at every college campus in America,we want to expand to restaurants and farms." said Simon.

mmlu_train_22463 | Getting enough sleep on a regular basis is one important way to protect the health of your heart. Poor sleep is associated with a range of cardiovascular problems, including high blood pressure, heart attack, and heart failure. Both men and women are at increased risk for these conditions. But we continue to learn that when it comes to health problems associated with sleep, the particular risks to men and women are not always the same. A new study suggests that for women who already have heart disease, poor sleep may be particularly dangerous to their heart health. Research indicates that poor-quality sleep--and waking too early in particular--is associated with increased inflammation among women with heart disease. There was no similar association found for men, suggesting that women with heart disease and sleep problems may be at particular risk for inflammation that can be damaging to the heart. Researchers at the University of California, San Francisco investigated the relationship between sleep quality and inflammation linked to coronary heart disease. They also sought information about how an association between sleep and inflammation might differ between men and women. Their investigation included 980 men and women at first, and 626 completed the 5-year study. All of those included were suffering for coronary heart disease. The average age of men in the study was 66. Women were slightly younger, with an average age of 64. Researchers measured sleep quality by asking participants to rate their sleep over the previous month. They also asked for reports of some of the most common sleep problems, including difficulty falling asleep, difficulty staying asleep, waking frequently throughout the night, and waking too early in the morning. After 5 years, researchers repeated tests for inflammation and once again sought reports on sleep quality and sleep problems. When they analyzed data for both men and women together, researchers found no links between inflammations and sleep quality. However, when they analyzed data taking gender into account, researchers found a relationship between inflammation and sleep existed for women, but not for men.

mmlu_train_27080 | In late summer or early fall the large, yellow seed heads of sunflowers will be ripening. If gardeners can keep off the birds and other wildlife trying to eat the seeds, they can have a large harvest. The bright yellow blooms will make a rainbow garden, brightening up any space. However, planting the sunflower seeds is a skilled job. Plant seeds no deeper than the full length of itself. Smaller sized sunflowers can be spaced a foot apart. Larger varieties will need to be spaced as far apart as three feet. This allows ripe plants enough space for the seed heads to ripen without knocking the ripe seeds off before gardeners have a chance to harvest them. Most sunflower seeds, especially those with eatable seeds, are large enough to handle without the need for seed sorters. This is why sunflowers make an excellent choice for a children's garden as well. Gardeners will want to mix plenty of soil fertilizers into the ground as sunflowers tend to be heavy feeders. Sunflowers can be slow starters and the tiny new plants don't seem to grow very rapidly. Gardeners should protect the new plants as they begin to grow. Once they get going, sunflowers are able to _ many weeds, making them easier to grow in the home vegetable garden than many other plants. Most pests and diseases are not a bother to the sunflower, however, more than one gardener has said that their lovely looking plants were destroyed overnight by hungry squirrels, mice or birds. To preserve their harvest, gardeners can cover the ripening seed head with stockings or net cloth to help keep the destroyers off the seeds. Planting sunflower seeds is easy and can help even the smallest gardener feel successful in their gardening attempts. Why do children love to grow sunflowers in their garden? | [

But if your parents are smaller than average, you may want to rethink that professional basketball career! The same goes for your body type. Have you ever heard someone say a person is "big boned?" It's a way of saying the person has a large frame, or skeleton . Big bones usually weigh more than small bones. That's why it's possible for two kids with the same height, but different weight, to both the right weight. Being overweight can run in someone's family, but it may not be because of their genes. Poor eating and exercise habits also run in families and these may be the reasons the members of a family are overweight. And even though some kids gain weight more easily than others, when they eat right and exercise, most kids can have a healthy weight that's right for them. It's true- the way you live can change the way you look. How much your weight is a balance between the calories you eat and the calories you use. If you eat more calories than your body needs to use, you will gain too much weight. If you spend you free time watching TV, your body won't use as many calories as it would if you played basketball, skated, or went for a walk. But if you eat more and exercise less, you may become overweight. On the other hand, if you eat less and exercise more, you may lose weight. _ might be the most important in determining your size and weight. | [

mmlu_train_7699 | Farmers, especially in developing countries, are often criticized for cutting down forests. But a new study suggests that many farmers recognize the value of keeping trees. Researchers using satellite images found at least ten percent tree cover on more than one billion hectares of farmland. That is almost half the farmland in the world. Earlier estimates were much lower but incomplete. The authors of the new study say it may still underestimate the true extent worldwide. The study found the most tree cover in South America. Next comes Africa south of the Sahara, followed by Southeast Asia. North Africa and West Asia have the least. The study found that climate conditions alone could not explain the amount of tree cover in different areas. Nor could the size of nearby populations, meaning people and trees can live together. There are areas with few trees but also few people, and areas with many trees and many people. The findings suggest that things like land rights, markets or government policies can influence tree planting and protection. Dennis Garrity, who heads the World Agroforestry Center, says farmers are acting on their own to protect and plant trees. The problem, he says, is that policy makers and planners have been slow to recognize this and to support such efforts. The satellite images may not show what the farmers are using the trees for, but trees provide nuts, fruit, wood and other products. They also help prevent soil loss and protect water supplies. Even under drought conditions, trees can often provide food and a way to earn money until the next growing season. Some trees act as natural fertilizers. They take nitrogen out of the air and put it in the soil. Scientists at the Center say the use of fertilizer trees can re-duce the need for chemical nitrogen by up to three-fourths. Trees also capture carbon dioxide, a gas linked to climate change. Through the study, the researchers found that _ | [

mmlu_train_28745 | The new iPhone 3G should please everyone . Its look and feel are only slightly improved, but a faster network loads Web pages more quickly , true GPS functionality allows it to easily find places nearby , and the new $199 price(down from $400) makes it an affordable luxury. Before deciding whether to buy, however , make sure you can actually take advantage of the iPhone 3G's high-speed data network. 3G stands for third-generation , which in non-geek speak translates to Web pages and mail messages that, ideally, load about three times faster than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf the Web at the same time . That's great, if you live or work in a place where the 3G network of AT&T (the sole wireless carrier of the iPhone) is active. That's not so great in cities like New York where AT&T's cellular coverage is awful. As one of my colleagues in New York City, who bought the original iPhone , commented , "It's just a toy . You can't make phone calls on it, so I carry my Verizon phone with me all the time."

mmlu_train_22229 | Your teenage daughter is supposed to be doing homework, but you catch her chatting online. She tells you that she's talking about the math test tomorrow. Before your eyes start rolling, listen up: teens are using social networking sites for more than just gossip, according to a new study by the National School Boards Association. The students who took part in the online survey, aged 9 to 17, said they spent almost as much time on social networking online as they did watching television. And it is what these kids are talking about online that is causing such a cheer: education. Of the students who took part in the study 60 percent reported that some of the most popular social networking topics were college planning, learning outside of school, careers, and schoolwork. They also reported posting writing and art projects that might have nothing to do with schoolwork. Ann Flynn, director of education technology for the National School Boards Association, says social networking tools into educational is the way forward. Flynn says a school in Cleveland, Ohio is posting students' book reports on a blog for students of their own ages, parents and other teachers to read and comment on. "If someone reacts other than the teacher, a child is much more likely to take an assignment seriously," Flynn says. Not only students but also parents can benefit. Now parents can go online and know what the class is doing. So, next time your child says her blog is educational, get curious, sit down and check out the blog with her. You might just learn something new yourself. We can infer from the text that Ann Flynn _ . | [

mmlu_train_38755 | Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest. Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes . To achieve giant size, a tree needs three things: the right place to establish its seedling, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees. In some parts of the world, populations of big trees are dwindling because their seedlings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear. Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. "During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic rate increases," explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth. The darks' theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions. Besides, big trees face threats from elsewhere. According to the passage, big trees make great contributions to the ecosystem because _ . | [

mmlu_train_82200 | Spending two or three hours playing outdoors each day can reduce the chance of becoming short-sighted, a research shows. It challenges the belief that short-sightedness is caused by computer use, watching TV or reading in weak light. The Australian government researchers believe that the sunlight is good for people's eyes. They compared the vision and habits of 100 seven-year-old children in Singapore and Australia. In all, 30% of the Singaporean children were short-sighted--this rate was ten times higher than Australian children. Both groups spend a similar amount of time reading, watching television and playing computer games. However the Singaporean children spent an average of only half an hour a day outdoors--90 minutes less than the Australian children. Professor Ian Morgan, from the Australian Research Council's vision Centre, said, "Humans are naturally long-sighted, but when people begin to go to school and spend little or no time outdoors, the number of short-sighted people gets larger. We're also seeing more and more short-sighted children in cities all around the world and the main reason may be that city children spend less time outdoors. Daylight can be hundreds of times brighter than indoor light. But why does playing outside prevent us from becoming short-sighted? Scientists believe that natural light has a special chemical which stops the eyeball from growing out of shape and prevents people from becoming short-sighted. So be outdoors. It doesn't matter if that time is spent having a picnic or having sports. How much time did the Australian children spend outdoors on average according to the research? | [

They are called herbivorous (plant-eating) animals. You may be surprised to learn that there are carnivorous plants as well as carnivorous animals. Plants that grow in poor soil need other food. They trap (catch by a trick) small insects and take their bodies as food. The pitcher plant is a common carnivorous plant. This plant has a clever trap like a pitcher or jar. It even has a lid to keep out of the rain. The mouth of the pitcher is covered with something sweet like honeydew . Insects come to the plant to feed on the honeydew. When they have eaten all that is round the mouth, they go into the pitcher to look for more. There is more honeydew deep in the pitcher and they go down to feed on it. The inner wall of the pitcher is covered with fine hairs. These hairs point downwards so that the insects cannot climb out of the pitcher. They are trapped in it.

"I like to try different dishes at each meal. So I had to throw away a lot of food because the bowls were too big. But now the dining hall offers small sizes.

Scientists are trying to find some answers. Some scientists believe insects will become a staple of our diet. Insects provide as many nutrients as ordinary meat and a great source of protein , they also cost less to raise than cows and use less water. About 1,400 species are suitable as food for humans. Many people have already eaten insects as a part of their diet. Locusts are popular in Africa, wasps are a dish in Japan, and crickets are eaten in Thailand. The Dutch government is preparing for insect farms and has invested one million euros into research. In the future, land and fresh water will be in short supply. It is possible that people need to find a reliable food source in the ocean. Scientists have already found one at the bottom of the food chain---seaweed. It has long been a staple in Asia, and countries including Japan have huge seaweed farms. Such farms can easily work in other countries and be very successful. The great thing about seaweed is that it grows at an amazing rate. It's the fastest growing plant on earth. Scientists are also working in the lab to solve the problem of food shortage. A few years ago, European scientists successfully produced lab meat, also known as cultured meat. They grew muscle tissue using stem cells taken from cows. The experiment was funded by NASA to see if lab meat was a food astronauts could eat in space. In 20 years' time , lab meat is likely to become a popular dish of our diet.

Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future. The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types. Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion ( ). One proposed solution to this problem is the automated highway system. When the auto enters the highway system, a retractable ( ) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car 's movements. The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer ( ) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.

mmlu_train_89467 | Many college students have given up taking class notes by hand. Instead, they type on computers. But scientists say that method is less helpful. If you need to remember something, write it. Writing notes by hand is much better for long-term memory of idea. So, turn off your computer if you want to remember something. Students who type notes on a keyboard often write down what the teacher says word-for-word. They may write without really thinking about what they are writing. These electronic notes contained more words. But scientists say it leads to " _ ." Transcription means to write down something exactly as you hear it. However, students taking notes by writing them, need to first process the information they hear. Then they record just the main parts. They use fewer words. This is because people usually write slower than they type. This kind of process leads to a deeper understanding. The scientists did a research. In the research, students listened to a teacher and then took a test. Some took notes by typing on a computer. The others took notes by writing them down. Both groups performed about the same in remembering facts. But students who typed their notes did much worse on conceptual questions. These questions required them to understand an idea. Also, scientists found that those who wrote their notes remembered conceptual information better a week later. Scientists believe that the students who took notes by writing them had a deeper understanding of ideas. Scientists know that students probably will still use their computers in class.

mmlu_train_15105 | Encouraging pupils to keep noise to a minimum should be a valuable component of all children's education, according to new research. Dr. Helen Lees, from Stirling University's school of education, says that "enforced silence" is seen as a punishment and often acts to _ children's natural ability. But she says that teaching children about the benefits of "enforced silence",--- deliberate stillness that gives them the opportunity to focus and reflect in a stress-free environment--- can have a significant effect on pupils' concentration and behavior. It is the latest in a string of researches to establish a link between the classroom environment and pupils' academic ability. A study almost a decade ago in London found that children's exam results were cut by as much as a third if they were taught in noisy classrooms. Teaching unions have also called for a limit of 26degC to be put on classroom temperatures because teachers and pupils struggle to work in hot conditions, and some educationalists claim that too much clutter on classroom walls can prevent children from concentrating. Dr. Lees said, "When we take some research on school settings and put it all together, what we see is that education without silence does not make much sense. In areas of better learning outcomes, better self- confidence and well-being measures, enforced silence in a person's life and an individual's education is shown throughout the relevant research to be a benefit." Dozens of schools across Britain have already introduced periods of "reflective silence" into the timetable. Kevin Hogston, head of Sheringdale Primary, south London, has just introduced a minute's silence at the start of twice-weekly meetings in which children are taught breathing techniques and encouraged to reflect. The school plans to introduce it into classrooms every day. What would be the best title for the text? | [

mmlu_train_23853 | When a dog loses a leg, the animal eventually figures out the best way to get around on three legs. In a short time, the dog learns to deal with its physical disability. Now, scientists have developed robots that behave in much the same way. We can find robots everywhere. Robots build cars, play chess and can clean your house. They may someday drive your car, too. Two robots, named Spirit and Opportunity, were sent to Mars on a mission to explore the red planet. Jeff Clune is a computer scientist with the University of Wyoming. He says robots also help people in natural disasters. Robots are deployed in search and rescue operations following an earthquake. They may someday also be used to examine the wreckage of a nuclear accident, like the one in Fukushima, Japan. Mr. Clune says robots can be sent to a lot of places said to be unsafe. "The problem is that all of those types of situations and environment are extremely unpredictable and dangerous. And it is very likely that robots and humans in those situations become damaged." He and other scientists are developing technology so that robots will continue operating after the first sign of injury. They want the machines to have the ability to make changes and continue performing until they can be repaired. Mr. Clune and researchers in France have added one more operation to the skill set of robots working under difficult conditions. They say they programmed a hexapod robot, one with six legs, and a robotic arm to learn how to deal with injury. Their findings were reported in the journal "Nature". Mr. Clune said that once the robots become damaged, they use their intuition and knowledge of how their body works to find a way to deal with the damage. He says the robots are also programmed with child-like curiosity. In other words, they are always asking questions and looking for answers. The whole process takes about a minute for the robots to find a way to overcome damage. Why are Mr.Clune and other scientists devoted to developing the technology? | [

mmlu_train_48098 | In the past two decades, the Chinese economy has undergone many reforms in an effort to compete more effectively on the international market.These reforms included allowing foreign hanks to offer credit cards to Chinese citizens, Now, researchers at the University of Missouri (MU)have found about 30 percent of Chinese urban households now own at least one credit card and the growth rate of credit card adoption has been an average of 40 percent per year between 2004 and 2009. Rui Yao, an assistant professor of personal financial planning at MU, says that this large growth in such a small amount of time has positive and negative implications for the Chinese economy. "With more and more people taking advantage of credit in China, it certainly increases potential consumer buying power," Yao said."However, we found that more than 90 percent of non-credit card users were unaware of safety issues existing in credit card use and more than 60 percent had little knowledge of the consequences of credit card debt.Thus lack of knowledge could create problems as credit card ownership is expected to grow at a rate of I percent a year." Yao found that would 72 percent of Chinese credit card holders were never late on their payments, only 55 percent were able to pay the full balance.She also found that 70 percent of Clones credit card holders said that credit cards contributed to overspending. Yao believes the Chinese could benefit from facial education designed to help them plan for their financial future and encouraging the Chinese to take advantage of debt in a responsible fashion is important for the Chinese economy."Appropriate use of debt can help households improve their quality of life as well as spur economic growth through an increase in market purchases."

mmlu_train_5403 | As rain begins to fall from the clouds, it is very pure. However, as it falls through the air it dissolves some of the gases in the air. It also collects bits of dust and microbes that are floating in the air. When the rain reaches the ground it begins to pick up more dust and dirt. Many kinds of mineral substances dissolve in the water. Sand and mud cannot dissolve in water. Since water is so important to us, it is very important that the water we use should be clean. Otherwise, we might get some of the diseases that are carried by water. Many microbes are harmful. They are so small that we cannot see them. These microbes must be removed or killed before the water is suitable for drinking. For example, microbes of diseases like cholera live well in water. If the water supply is not clean, people who drink this water may get these diseases. Thus, to provide people with clean water, the government purifies the water. Purification is a long process and includes three stages: storing, purifying and distributing . The first stage is storing. Man-made lakes are used for this purpose. Water from the rains, other lakes, streams and rivers is collected in the lakes. This water is usually dirty and muddy. In the second stage, water from the man-made lakes is filtered in a special pond. Stones, sand and other unwanted tiny things are caught in it. After that, tiny microbes are still present in the water. These microbes are removed by "airing" the water and by adding a chemical substance called chlorine to the water. This kills all the microbes in the water. After this, the water can be safely used for drinking. The third stage is the distribution of the purified water to homes, hospitals, offices, factories and other places. This is done through a network of pipes of various sizes. These pipes must be made of a suitable material. What is the purpose of adding chlorine to the water? | [

mmlu_train_24769 | People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020. In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races. Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer. "By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. " Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved. ks5u According to Richard Mason, what is the biggest challenge for driverless cars? | [

mmlu_train_32463 | A California man who was feeling sick almost died recently from a shocking cause. 26-year-old Luis Ortiz went to a hospital because of a headache and nausea(,). When doctors examined him, they were shocked to find a tapeworm larva in his brain. The story gets stranger. The larva was still alive. The creature had caused a cyst to form inside his head. The cyst was restricting the flow of liquids to different areas of his brain. The situation was so serious that doctors said they had to perform an emergency operation to remove the larva. A doctor who operated on Ortiz told him he had only 30 minutes to live. When the doctor pulled the worm out of his head, it was still moving. Luis Ortiz was a student at California State University in Sacramento. He began experiencing headaches in late August. But Ortiz said he did not think the headaches were serious. In September, he visited a friend and his parents in another city. That is when the pain got worse. His mother saw Ortiz throwing up and took him to a hospital emergency room. The doctors saved Ortiz's life. However, the surgery also affected him. Ortiz had to drop out of school and move back home. For now, he is not permitted to work or drive a vehicle. The U.S. Centers for Disease Control and Prevention says the U.S. has about 1,000 reported cases of tapeworms each year. The CDC adds that tapeworms are more common in developing countries with poor public health systems. The best way to avoid a tapeworm infection is to wash fruits and vegetables. Also, make sure meat is cooked thoroughly. The CDC suggests cooking all meats to an internal temperature of at least 63 degrees Celsius.

mmlu_train_42625 | The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very _ diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins. An example of the dangers of a restricted diet may be seen in the disease known as "beri-beri", which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted by a germ . He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain, it was thought this would be easier for weak and sick people to digest. Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients' plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain. Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice somehow prevented or cured beri-beri--even that a lack of some ingredient in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.
