mmlu_train_54760 | October 15th is Global Handwashing Day.Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap. Experts say people around the world wash their hands but very few use soap at so-called critical moments.These include after using the toilet, after cleaning a baby and before touching food. Global Handwashing Day is the idea of the Public-private Partnership for handwashing with soap.The goal, they say, is to create a culture of handwashing with soap.The organizers say all soaps are equally effective at removing disease-causing germs.They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap.Rub it into all areas, including under the fingernails.Then, wash well under running water.Finally, dry your hands with a clean cloth. The Partnership says soap is important because it increases the time that people spend washing.Soap also helps to break up the dirt that holds most of the germs.And it usually leaves a pleasant smell, which increases the chances that people will wash again. It also says that washing hands with soap before eating and after using the toilet could save more lives than any medicine.It could help reduce cases of diarrhea, which is the second leading cause of child deaths, killing more than one and a half million children a year, by almost half. What does the author intend to tell us in the passage? | [

mmlu_train_54025 | Chinese students aren't the only ones who have a sleep loss problem. In Australia, teenagers are also missing out on, on average, one hour's sleep every night during the school week. Organized activities and homework push bedtimes later, the first large-scale Australian study of children's sleeping habits has revealed . Their sleep deprivation is enough to cause "serious drop-offs in school performance, attention and memory", and governments should consider later or flexible school start times, said the study's leader, Tim Olds. ks5u His survey, of more than 4,000 children aged 9 to 18, found those who slept least did not watch more television but spent their time socializing with family or friends or listening to music. "Almost all children get up at 7 or 7:15 -- they have to get to school on time," said Olds. He favors a later start over an earlier finish because he believes organized sports and activities would still consume the latter end of the day. Olds' research also establishes lack of sleep as a cause of weight gain in children, and a possible source of future problems with depression, anxiety and increased susceptibility to illness. It was already known that overweight children sleep less, but Professor Olds found sleep duration was strongly linked to weight across the full range of body sizes. The thinnest children sleep 20 minutes more than the _ . This showed being overweight had no specific effect on sleep patterns, and it was more likely that shorter sleep times stimulate appetite and make kids hungry. The US National Sleep Foundation says teenagers aged 13 to 18 need eight to nine hours' sleep a night. Younger school-aged kids need 9 to 11 hours. On that basis, Professor Olds said, half of Australian children are under-sleeping on weekdays and a quarter on weekends. The Australian students surveyed don't sleep enough because they spend more time on the following EXCEPT _ . | [

mmlu_train_40073 | A town in Oxfordshire has become the first in the UK to have biomethane gas from human waste piped to their homes for gas central heating and cooking. Up to 200 families in Didcot now receive the gas via the national gas power system. Head of energy and technology at British Gas, Martin Orrill, said customers wouldn't notice any difference as the gas is purified to the highest standard and has no smell. The gas is produced at a sewage treatment works plant in Didcot. The entire process takes only less than three weeks, with the sewage being collected and sent first to settlement tanks. The solid waste material is then fed into digesters, where anaerobic bacteria digest the sewage, with the aid of enzymes to speed up the process. The digestion process produces methane, which can be burned to drive machines to produce electricity, or can be purified and fed into the gas network and piped to homes and businesses. British Gas says supplying the gas rather than electricity is far more efficient since around two-thirds of the energy is lost in producing electricity. Partners in the Didcot project, British Gas, Scotia Gas Networks, and Thames Water, all hope to expand the process to other towns, and other companies such as Ecotricity and United Utilities have also announced biomethane projects being planned. One of these projects, in Manchester, could be supplying 500 homes with biomethane by mid next year. Another British Gas project in Suffolk will provide gas from digestion of brewery wastes to around 235 families. The Didcot project cost PS2.5m and was influenced by promises of government aids aimed at encouraging companies to develop renewable technologies. An EU directive means the UK must ensure at least 15 percent of its energy is from renewable sources by 2020. The UK produces about 1.73 million tons of sewage annually. If all sewage treatment works in the UK were fitted with the technology, they could supply gas for up to 350,000 families. According to British Gas, the biomethane gas had better be used _ . | [

Noise can be caused by many kinds of machines, such as motorcycles, jet planes and farm tractors . Rock music is also noise. What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant loud noise can cause a loss of hearing. Scientists use a unit of measure called decibel to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands can measure over 120 decibels.

mmlu_train_54829 | Most people today think of sleep as one continuous period of downtime.This is not the way people used to sleep.According to researchers,in earlier times,people divided sleep by first sleeping a few hours,waking up,then going back to sleep.In the first period,you would typically sleep until midnight or shortly afterwards.Halfway through the night,you came out of first sleep,you would stay in bed and relax quietly.It was called the watching period.Then you would start to feel sleepy.so would return to bed and tall asleep again for your second sleep.This period would continue until early morning when daylight arrived.With no artificial lighting in homes,people naturally woke up early to take advantage of sunlight. Before the 18th century, people had no gas or electricity in their homes.Fire,candles,or oil lamps were the common forms of lighting.This lack of artificial lighting in homes contributed to people's sleep patterns.It made sense for people to go to bed early. Today,human may consider divided sleep a strange habit,but sleep researchers say that it is actually a more natural sleep pattern.Dr.Thomas Wehr of the U.S.National Institute of Mental Health has studied human sleep.He thinks that modern sleep problems occur because the older, natural way of sleep is breaking through the more recent continuous sleep pattern.Wehr and other scientists believe that artificial lighting has altered the way people sleep.In a research study,he asked 15 adults to rest and sleep in darkness for 14 hours(from 6:00 P.M.to 8:00 A.M.).At first,the subjects took a few hours to get to sleep,and then slept 11 hours a night.Then overtime,they switched to divided sleep.They fell asleep for about three to five hours in the evening,stay awake for an hour or two,and then slept again for four hours till early morning. We modern humans generally do not practice divided sleep.However, many of us have the experience of waking up in the middle of the night.We usually consider this a sleeping"problem".but perhaps we should look at it as natural behavior.Divided sleep may be the way we should all be sleeping.A first sleep followed by a relaxation period and a second period of sleep could help all of us to beat the stress of our fast-paced lives.

mmlu_train_66006 | The New Year holidays bring delicious food, but no one wants a weight problem after they are over. American Food psychologist Brian Wansink has recently published "Mindless Eating: Why We Eat More Than We Think". The book explains why we eat what we eat and how we can control our eating. Most of his suggestions are based on scientific studies he has conducted as director of Cornell University's Food and Brand Lab. Here are 10 of his tips for the holiday season: 1 People tend to eat more when distracted by conversation or a game on TV. Setting your chopsticks down and giving full attention to the conversation will prevent overeating. 2 See it before you eat it. Eating chips from a bowl led one group to consume 134 fewer calories than others who ate straight from the bag. 3 Keep the evidence on the table, such as chicken bones, cake papers, and candy wrappers . Studies have shown that leaving the wrappers and remains of food on the table leads diners to eat less. 4 Budget calories. Do not eat the appetizer if you know you want dessert. It will be easier to count how many calories you consume. 5 Sit next to the slowest eater at the table and try to eat slower than him or her. Always be the last one to start eating, and set your chopsticks down after every bite. 6 Don't avoid the food you really want, but eat it in smaller portions . 7 The more variety, the more people will eat. When there are a smaller number of dishes on the table people eat less. 8 Put foods that are unhealthy in the back of the cupboard , the back of the refrigerator, the back of the freezer. You can also "hide" food that is bad for you. Office workers ate 23 percent less candy when it was in a white, covered candy dish than in a see-through one. 9 Use small bowls. A study found that people serving themselves from smaller bowls ate 59 per cent less. 10 Use tall, narrow glasses for drinks. Even experienced waiters poured more into short, wide glasses than into thin ones. According to the tips, people can control their eating and drinking by _ . | [

mmlu_train_54133 | Running like the wind, roaring like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China. This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund. The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950s, there were over 4,000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species. Sixty-six of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves. "Breeding has damaged the quality of the species," said Pei Enle, deputy director of the Shanghai Zoo. To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts and can hunt wild animals by themselves at the African base. "South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in," said Lu Jun, office director of the National Wildlife Research and Development Centre. "We tried in Fujian Province, but it was not successful as there was not a complete eco-chain and there was a lack of space." The tigers should return to China in 2009 when the reservations in Fujian are ready. What is the main reason for the South China tiger becoming one of the world's top ten most endangered species? | [

mmlu_train_67673 | A 15-year-old student who invented a flashlight getting power from the holder's body heat is going home today from California with a big prize and a chance to do further research. Ann Makosinski was the only Canadian among the four winners at Google's international science competition. Thousands of young scientists from around the world took part in the competition. Winning the science and technology competition was "a surprise". Ann said, "I think it will have a great influence on my future." Ann thanked her family for encouraging her interest in science and said that her first toy was a box of transistors . The ideas for the invention came from seeing unwanted batteries and her friend's experience. When Ann visited a friend in the Philippines, she saw the friend couldn't study when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries - Hollow Flashlight. In her project, Ann wrote "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5degCtemperature difference between the holder's body and the environment around to produce light." A video of Ann explaining how she created the flashlight has been watched more than 1.4 million times on the Internet. Though Ann was successful, she has not made a decision about her career path. Ann hope that she can find a way to join her love of film and science together. The four winners were chosen from 15 final competitors from eight countries.

mmlu_train_66702 | Nature is full of color, from rainbows and roses to butterfly wings and peacock tails. Even the fruits and vegetables you eat have different colors: blue blueberries, red strawberries, green broccoli, and orange carrots. Plant and animals often use color to attract attention. The substances responsible for these colors belong to a class of chemical called antioxidants . Plants make antioxidant to protect themselves from the sun's ultraviolet(UV) light. Ultraviolet light causes chemicals called free radicals to form within plant cells. They can destroy parts of plant. Free radicals also have damaging effects on human beings. Some of these effects like wrinkled skin can be seen. The damage is caused by the free radicals attacking cells in our bodies. Certain cancers and heart disease are linked to free radicals. Our bodies have natural defences for fighting off free radicals. While we are young, our defences are pretty strong. However, they get weaker as we get older. The body's built-in defences can only go so far without extra help. The key to fighting free radicals with fruits and vegetables is to mix and match colors. It's like sunscreen for the inside of your body. Go for a range of very bright colors. Colorful foods contain hundreds of healthy chemicals not found anywhere else. Research into how chemicals in blueberries affect the brain's function in rats suggests that these chemicals may help our own brains work more efficiently. Don't just blame the sun. Ultraviolet light isn't the only source of free radicals. If you breathe polluted air such as smog, automobile exhaust , or wasted gas from a factory, you take in chemicals that also cause such damage. And, the body itself produces free radicals as it processes food. Which of the following not true? | [

mmlu_train_20785 | A clinic in West Kalimantan, Indonesia, works to support the health of people and forests. Kinari Webb is an American doctor who helped start the non-profit group that operates the clinic. The group is known as ASRI. Dr. Webb says most communities value the local forests, but illegal logging was often their only way to earn money to pay for health care. "Villagers know that if they protect the forest, that's good for their long-term well-being. But if they have no money to see a doctor, they have to do illegal logging," said Dr. Webb. The clinic is in Sukadana, a village outside Gunung Palung National Park. Each month someone from ASRI visits the surrounding villages to see if they are actively logging or burning land within the park. Communities that do not take part in illegal logging pay about 40 percent less for health care than those that do. Also, the clinic uses a barter system. Patients can pay with things like handmade baskets, labor exchanges, young trees or fruit they grow. Patients learn about environmental conservation as they wait to register at the clinic. Many of the 70 staff members also help communities learn about organic farming and other ways to earn money. In May, ASRI started a program to identify forest "guardians". These guardians work with the community to try to prevent illegal logging. One of the guardians says he entered the program because ASRI helped his son recover from tuberculosis . The clinic is small, but very busy. However, people did not trust the clinic at first. They wanted to go to the only hospital in the area. Yet its resources are limited and villagers often have to travel more than two hours to get there. Now, people happily share stories about the clinic. Amelia's mother is one of them. She started going there when her daughter was eight months old. She says the treatment is good. Dr. Webb smiled when she heard that. Dr. Webb said: "Health care is an incredible key. And everyone everywhere around knows that we really care and that we are helping save their lives." We can infer that _ . | [

mmlu_train_55326 | People who drink moderately , exercise, quit smoking and eat five servings of fruit and vegetables each day live on average 14 years longer than people who adopt none of these behaviors, researchers said on Tuesday. Much evidence has shown these things contribute to healthier and longer lives, but the new study actually quantified their combined effect, the British team said. "These results may provide further support for the idea that even small differences in lifestyle may make a big difference to health in the population," the researchers wrote in the journal PLoS Medicine. Between 1993 and 1997 the researchers questioned 20,000 healthy British men and women about their lifestyles. They also tested every participant's blood to measure vitamin C intake, which shows how much fruit and vegetables people ate. Then they assigned the participants aged 45-79 a score of between 0 and 4, giving one point for each of the healthy behaviours. After allowing for age and other factors that could affect the possibility of dying, the researchers determined people with a score of 0 were four times as likely to have died. Also a person with a health score of 0 had the same risk of dying as someone with a health score of 4 who was 14 years older. The lifestyle change with the biggest benefit was giving up smoking, which led to an 80 percent improvement in health, followed by eating fruits and vegetables. Moderate drinking and keeping active brought the same benefits. With this information, public-health officials should now be better encouraging behavior changes likely to improve the health of middle-aged and older people.

mmlu_train_51364 | In the 1950s, a family that owned a farm near Beulah, Michigan kept a bull chained to an elm . The bull paced around the tree, dragging the heavy iron chain, which led to a groove in the bark . The groove deepened over the years. Though for whatever reason, it did not kill the tree. After some years, the family took their bull away. They cut the chain, leaving the loop around the tree and one link hanging down. Then one year, agricultural disaster struck Michigan in the form of Dutch Elm Disease. All of the elms lining the road leading to the farm became infected and died. Everyone thought that the old elm would be the next. The farm owners considered doing the safe thing: pulling it out and cutting it up into firewood before it died. But they simply could not bring themselves to do it. It was as if the old tree had become a family friend. So they decided to let nature take its course. Amazingly, the tree did not die. Nobody could understand why it was the only elm still standing in the county! Plant experts from Michigan State University came out to observe the tree. They observed the scar left by the iron chain, now almost completely covered by bark. The experts decided that it was the chain that saved the elm's life. They reasoned that the tree must have absorbed so much iron from the chain that it became immune to the virus. It's said that what doesn't kill you will make you stronger. Or, as Earnest Hemingway put it, "Life breaks us all, but afterwards, many of us are strongest at the broken places." What actually saved the elm? | [

mmlu_train_10706 | People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular. Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco burns, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person's breathing muscles. Smokers usually take in small amounts that the body can quickly break down. Nicotine can make new smokers feel dizzy or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers' risk of heart disease and stroke. Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.

mmlu_train_36816 | William Herschel was born on November 15th, 1738 in Hanover in a family of musicians. In 1757,he fled to England and began earning a living as an organist and later composer and conductor. In 1772, he convinced his sister Caroline to join him as a singer. In their spare time the brother-sister team became occupied in astronomy. William died at his home in Slough, near Windsor on August 25th,1822,and Caroline on September 1st,1848. Herschel's first major discoveries were to show that Mars and Jupiter exhibit axial rotation . Herschel struck fame in 1781,when on March 13th he discovered the planet Uranus while engaged in work aimed at determining stellar parallax .This being the first new planet discovered since ancient times, Herschel, until then a mere amateur astronomer relatively unknown even in England, became world-famous. Adopting a historically proven strategy, Herschel named the new planet Georgium Sidum,in honor of the then ruling English king GeorgeIII. The trick worked once again, as King GeorgeIII gave William and Caroline the titles of"The King's Astronomer"and"Assistant to the King's Astronomer", an honor which came with a life's pension for both. In 1782 they moved to Bath, and shortly thereafter to Slough, and from this point on William and Caroline could devote themselves entirely to astronomy. The Herschels went on to discover two moons of Uranus in 1787. While Caroline became increasingly occupied with the search for comets at which she was quite successful, William became for a time interested in the Sun. Inspired by Wilson's 1774 work, he put forth the theory of sunspots ,an opinion that continued to exist well into the nineteenth century. In 1800,he became interested in the solar spectrum ,and uncovered the first evidence for solar energy output outside of the visible spectrum, in what is now known as the infrared .In 1801, he published two papers that effectively started the field of solar influences on Earth's weather.

mmlu_train_14640 | Every year, World Blood Day is celebrated by blood services worldwide on 14 June, the birthday of Nobel Prize winner Karl Landsteiner, the man who discovered the ABO blood group system. If you have every thought of becoming a blood donor, just register to do it. And you should never worry about the donation. Just under a pint (around 470ml) of blood is taken at one sitting. This amount is no more than 13 percent of your total blood volume, and is quickly replaced by your body. It may come as a surprise, but whole blood is only rarely used. Different blood components are used to treat a range of conditions. None goes to waste. Read blood cells are frequently used to replace heavy blood loss after an accident, surgery or childbirth. White blood cells and antibodies are used to help people fight infections if their immune system doesn't appear to be responding to antibiotics . Plasma ,the straw-coloured fluid which carries the blood cells and contains proteins, are used to treat burned patients. First-time donors should be aged between 17 and 65, weigh at least 50kg and be in good health. If you have donated before, you can start being a donor again up to your 70th birthday. Although most people are able to give blood, some people who pose health risks or are at a higher risk of having come into contact with an infectious disease are no tasked to be donors. Pregnant women or those who have had a baby in the last 9 months should not donate blood. Blood has a very short shelf life. Some blood components can be kept longer than others, for instance red blood cells will keep for 35 days but platelets for only five. Remember, you should wait at least 16 weeks before donating blood again. People should never worry about the donation mainly because _ . | [

mmlu_train_59989 | Visiting animals in their natural homes may sound like a great idea that helps to save them, but is it ? Researchers writing in Trends in Ecology & Evolution on Oct9 said that the interactions between wild animals and friendly eco-tourists who want to take their pictures may put animals at greater risk of being eaten. It is clear that many people visit protected areas every year. "Recent data showed that protected areas around the globe have 8 billion visitors per year; that's like each human on Earth visited a protected area once a year, and then some!"said Dainel Blumstein of the University of California, Los Anglels. "This amount of nature tourism and eco-tourism can be added to the long list of ways in which humans cause fast environmental change. The basic idea of the report the report is that humans change the ways animals act and those changes might affect other parts of their lives, according to Science Daily. Those changes in behavior and activity may put animals at risk. "When animals spend time in 'harmless' ways with humans, they may let down their guard," Blumstein said. As animals get used to feeling comfortable with humans, they may become braver in other situations, he says . "If this bravery continues when they meet real predators , then they will die more often when they meet them." Eco-tourism is in some ways similar to making animals live in human homes or in cities. In all three cases, regular interactions between people and animals tame. Evidence has shown that silver foxes that live with people become more laid-back and less fearful; this results from evolutionary changes but also from spending time with humans. Simply put , as Blumstein asked in the Scientific American magazine:"Does eco-tourism make animals _ ?" And that's not all - humans can also scare away natural predators , creating the so-called "human shield effect" and a safe environment for smaller animals that might make them braver, too. When humans are around, for example, vervet monkeys don't see as many leopards trying to eat them. Blumstein says they hope to do more research into humans' interactions with wildlife. Scientists will "now have to understand better how different species and species in different situations react to humans and when humans might put them at risk.

mmlu_train_34128 | The coyote , that clever animal of wide-open spaces, has come to the nation's capital. In fact, coyotes have spread to every corner of the United States, changing their behaviors to fit new environments and causing researchers to deal with a troublesome new kind of creature: the city coyote. The coyote originally lived in the middle of the continent. One of its most obvious characters is its smartness, which has made the animal a notorious pest. Hunters trapped, shot and poisoned more than a million coyotes in the 1900s. It's still one of America's most hunted animals. Yet the coyote has survived. How has the coyote shown this extraordinary ability? "I guess if you wanted to use one word, it'd be ' _ '," says Eric Gese, an expert at Utah State University. Coyotes can live alone, in pairs, or in large packs like wolves; hunt at night or during the day; occupy a small region or an area up to 40 square miles; and live on all sorts of food, from lizards and shoes, to ants and melons. Unbelievably people helped coyotes increase when they killed most of the wolves in the United States. The spreading of coyotes into city areas, though, is recent. They travel at night, crossing sidewalks and bridges, running along roads and ducking into culverts and underpasses. No one knows why coyotes are moving into cities, but experts explain that cleverer, more human-tolerant coyotes are teaching urban survival skills to new generations. Occasionally, coyotes might attack human beings. There have been about 160 attacks on people in recent years. Therefore, people have been consistently told not to feed coyotes or leave pet food unsecured. That, plus a large trapping program in the neighborhood, has cut down on the coyote population.

mmlu_train_44441 | The economic growth that many nations in Asia and increasingly Africa have experienced over the past couple of decades has transformed hundreds of millions of lives - almost entirely for the better. But there's a _ to that growth, one that's evident - or sometimes less than evident - in the smoggy, smelly skies above cities like Beijing, New Delhi and Jakarta. Thanks to new cars and power plants, air pollution is bad and getting worse in much of the world, and it's taking a major toll (,) on global health. How big? According to a new analysis published in the Lancet, more than 3.2 million people suffered deaths from air pollution in 2010, the largest number on record. That's up from 800,000 in 2000. And it's a regional problem: 65% of those deaths occurred in Asia, where the air is choked by diesel soot from cars and trucks, as well as the song from power plants and the dust from endless urban construction. In East Asia and China, 1.2 million people died, as well as another 712,000 in South Asia, including India. For the first time ever, air pollution is on the world's top - 10 list of killers, and it's moving up the ranks faster than any other factor. So how can air pollution be so damaging? It is the very finest soot - so small that it roots deep within the lungs and then enters the bloodstream - that contributes to most of the public - health toll of air pollution including death. Diesel soot, which can also cause cancer, is a major problem because it is concentrated in cities along transportation zones affecting overpopulated areas. It is thought to contribute to half the deaths from air pollution in urban centers. Fro example, 1 in 6 people in the U.S. live near a diesel - pollution hot spot like a rail yard, port terminal or freeway. We also know that air pollution may be linked to other non - deadly diseases. Fortunately in the U.S. and other developed nations, urban air is for the most part cleaner than it was 30 or 40 years ago, thanks to regulations and new technologies like the catalytic converters that reduce automobile emissions. Govemments are also pushing to make air cleaner - see the White House's move last week to further tighten soot standards. It's not perfect, but we've had much more success dealing with air pollution than climate change. Will developing nations like India eventually catch up? Hopefully - though the problem may get worse before it gets better. The good news is that it doesn't take a major technological advance to improve urban air. Switching from diesel fuel to unleaded helps, as do newer and cleaner cars which are less likely to send out pollutants. Power plants - even ones that burn mineral fuels like coal - can be fitted with pollution - control equipment that, at a price, will greatly reduce smog and other pollutants. But the best solutions may involve urban design. In the Guardian, John Vidal notes that Delhi now has 200 cars per 1,000 people, far more than much richer Asian cities like Hong Kong and Singapore.

mmlu_train_85527 | Most middle school students find it boring to learn English. But students in Yat Sen middle school in New York, US, don't think so. Why? Because they are in the school of One Program, which asks students to work on their own or in small groups on computers to have math lessons. "The program gives the students a new learning style. No traditional classroom can compare with it. We give each lesson according to the students' interest and their strong and weak points," said JoelI. Klein, the school's head teacher, "we're looking for a new way that interest students children." Students enjoy these math lessons, especially lessons with video games. They must find out the answers to math problems to get through the game. One such game is Dimension M. As students move through mazes with their keyboards, some questions come up. Caleb Deng had to answer the question: What is 5+ (6x3)? He _ on paper quickly because there was just a minute left to play. " I was right," said Deng, 14, as he ended the game with a high score .

mmlu_train_11549 | The koala is one of Australia's most treasured creatures, which is a lovely little creature. But now, it is in big trouble. Affected by habitat loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population, that is worrying many scientists about the fate of the koala. The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food. Treating Chlamydia in wild koalas is a challenge. There is no treatment available for _ . Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala;it is up to each region to make management plans for its koala population. The good news is that researchers are working to test a vaccine that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccil1e more widely. But it's impossible to vaccinate all wild koalas. Another possibility would be to make vaccine distribution a routi11e part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs. While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may buy enough time to give researchers a chance to solve some of the other problems facing Australia's koalas. We can learn from the text that the vaccine _ . | [

mmlu_train_9172 | New research suggests that speaking more than one language may delay different kinds of dementia , that is the loss of mental ability. In fact, researchers say, speaking two languages appears to be more important than the level of education in defending against dementias. A study in India examined the effect of knowing more than one language in delaying the first signs of several dementias. Researchers studied nearly 650 people whose average age was 66. 240 of those studied suffered from Alzheimer's, the most common form of mental decline . 391 of the _ spoke two or more languages. Researchers found the dementias began about four-and-a-half years later in those who spoke two languages compared to those who spoke only one language. The level of education had no effect on the age at the first sign of dementia. Thomas Bak, from the Center of Cognitive Aging at the University of Edinburgh in Scotland, who helped to organize the study, suggests that individuals who speak more than one language train their brains by moving back and forth between different words and expressions. He also believes this effort improves what scientists called executive functioning, which often weakens in people with dementias. He states that researchers found there was no extra gain in speaking more than two languages. Mr Bak says it does not appear important whether you learn another language at a young age or later in life. It's not something that "you missed the boat when you do not do it as a baby." It is something that is still quite useful and powerful when you do it as an adult. This passage may probably be seen in _ . | [

mmlu_train_10869 | Going to outer space is a little like going camping. You have to carry with you all the food and equipment you need for your trip, so your food can't be too heavy or hard to prepare. Plus, there are no refrigerators to keep food cold and fresh. Food with all the water dried out is lightweight and doesn't spoil. So, many space foods are dried on Earth and stored in special packets. Some taste good right out of the packet. On earth, gravity is the force that keeps your feet on the ground and your sandwich on your plate. But there's no gravity in space. To keep food from floating away, astronauts on the Space Shuttle attach the packets to a special tray. The tray can be fixed to a wall or to the astronaut's lap. To prepare their food, astronauts use liquid forms of salt and pepper. The liquid sticks to the food better. Regular salt and pepper would float away, maybe up an astronaut's nose. Liquids float right out of cups and glasses, though. So astronauts drink everything from a small bag with a straw that can be closed. Astronauts say that most space foods taste pretty good. Some, such as apples and pudding, are the same as the foods you eat on Earth. Astronauts eat tortillas instead of bread because they make fewer crumbs . Floating crumbs could get stuck in equipment or an astronaut's eye. Your body used food in space the same way it does on Earth. Your body must deal with waste in space too. During takeoff the landing, astronauts can't leave their seats to go to the bathroom. They wear diapers under their spacesuits instead. The Space Shuttle has a bathroom the size of a small closet. The toilet has bars that keep astronauts from floating away. A strong flow of air is used instead of water to flush waste down the toilet. Back on Earth it's flushed away-or sometimes studied by scientists. We can infer from the passage that astronauts _ . | [

"We are going to talk about extreme life extension," he says. "I am talking in details about allowing us to go into our second century of life with the energy that you have when you are a young person." Owing to advances in technology and research on how diet affect the aging process, Dr Oz says it might be possible for some people to live to see their 120th birthdays. There's one man in Oprah's audience who Dr Oz says may become the first man in history to live to be 150 years old. Joe Cordell is one of thousands around the world who believe they've found the key to an extreme long life --- calorie restriction leads to a longer, healthier life. At 59 Joe weighs 130 pounds. He may not look like a person who needs to count calories, but as part of his life extension program, he inspects every mouth of food that passes through his system. Every day for the past seven years, Joe has limited himself to about 1,950 calories. He believes that by eating less and restricting his caloric intake, he will _ a genetic switch that slows the aging process. Joe doesn't take away himself of food. Instead, the then 52-year-old father filled up on natural fruits, vegetables and lean proteins that were packed with necessary vitamins and nutrients. "Whenever you are thinking about calorie restriction, you should continually think about getting the most nutritional amount per calorie," Joe says. In keeping with this principle, Joe starts every morning with three apples...but he only eats the peels. "Most of the fiber is in the peel, and more importantly, most of the nutrients are in the peel," he says. "It is important to eat some nuts with breakfast so that you do take in some fat, some healthy fats," he says. "I think it helps the absorption of the nutrients, and it is very filling." For lunch, Joe usually eats a large salad, loaded with vegetables. At dinnertime, he and his family enjoy lean meat or fish and more vegetables. When Joe started practicing calorie restriction, he weighed 175 pounds. Since then, he has lost 45 pounds, and he says he hasn't had a cold in seven years. Though he is in his "golden years", researchers studying Joe say he has the body of a 20-year-old athlete. According to Joe, the appropriate fat intake may help _ ? | [

Their special bodies make them adapt to life at sea. However, sea turtles maintain close ties to land. Female sea turtles have to go to the seaside to lay their eggs in the sand; therefore, all baby sea turtles begin their lives on land. Most research on sea turtles has been focused on female turtles nesting and the baby sea turtles in the nest, largely because they can be found most easily. After decades of studying sea turtles, much has been learned about. However, many mysteries still remain. Researchers do not yet know how long baby turtles spend in the open sea, or exactly where they go. People believe they spend their earliest years floating in the sea, where they do little more than eat and grow. Once turtles reach dinner-plate size, they appear at feeding grounds in waters near the shore. They grow slowly and take between 15 and 50 years to grow old enough to bear baby sea turtles, depending on the species. There is no way to know the age of a sea turtle from its physical appearance.
