Call 119----Never try to put out a fire yourself. Tell 119 where you are and what is on fire. 3. Keep down close to the floor----There's less smoke down there, so it's easier to breathe and see where you are going. 4. Test the door---- the door is cool, open it carefully. If the door is hot, don't open it! Try to find a different way out. 5. Get out---- not stop to pick up anything. A fire can become very big in afew seconds! 6. Don't use the lift ----ways use the stairs. The lift may go wrong and keep you inside. 7. Don't go back---- if you have left your pet or favorite toy inside, don't go back for it.

mmlu_train_7407 | Swimming in the water of Hawaii's Big Island is a fun experience. But it can be more exciting if there are dolphins swimming around and jumping out of the sea too. For many people, it would be a wonderful dream to swim with these lovely animals! However, this may not be good for dolphins. They may get hurt because of human interaction . Dolphins are active and usually look for food at night. In the day, they like to rest in shallow bays . Many people think the dolphins are awake during the day as they swim. But when they sleep they rest half of their brain and keep the other half awake to breathe, so they may be sleeping even when they're swimming in the water. From 2010 to 2013, spinner dolphins of Hawaii's Big Island were exposed to human activities more than 82 percent of the time, according to Julian Tyne, a researcher at Australia's Murdoch University. The National Oceanic and Atmospheric Administration (NOAA) says disturbing the animals in their near-shore habitat could force them to swim to less favorable places, putting them at risk of attack by sharks and other animals. Besides, when people are around, dolphins become more active. Thus, they can't get enough sleep. "Disturbing their resting behaviors can actually affect their long term health and the health of the dolphin population," Ann Garrett of NOAA's National Marine Fisheries Service told the Associated Press. As a result, the NOAA wants to make rules to help protect the dolphins. For example, the agency may ban swimming with the Hawaii spinner dolphins. Or they may stop people from swimming in shallow bays when the dolphins are resting. Tour operators must also be taught to watch for signs to know when the dolphins are in their resting state. When dolphins are disturbed in their near-shore habitat, they _ . | [

mmlu_train_44973 | What would you think if you went back to school on Monday and there were no desks or chairs in your classroom? That's what some fourth-and-fifth-graders at a school in Minnesota discovered earlier this year when they took part in a research project to see if changing their classrooms would make them more active. Researchers from the Mayo Clinic were concerned about reports that as many as half of American kids could be seriously overweight - or obese - by the year 2014. So they set up a different kind of classroom, which you might see in the future. Instead of desks, the Elton Hills Elementary students had adjustable work stations where they could stand, kneel on mats or sit on big exercise balls. Students were given laptops and iPods that allowed them to move and learn at the same time. Sensors were attached to the kids' legs to calculate how many calories students burned in their new set-up. Their typical school day was probably not anything like yours. One group of students downloaded an audio file of their teacher reading a book; they listened to it while walking for exercise. Another group took a spelling test by listening to their iPods. Some students liked the freedom, but others missed the traditional classroom. "I don't like standing up," Mariah Matrious said. "My legs get tired, and I like sitting down. " So, did the experiment work? Researchers still are studying the data, but early results indicate that the kids did move around more in the new classroom. "It showed us that, given the opportunity to move, kids will move," said researcher Lorraine Lanningham-Foster. That's important because studies have shown that even simple movement - climbing stairs instead of taking an elevator , for example, or washing dishes by hand instead of loading the dishwasher - can be as important as formal exercise when it comes to controlling one's weight. The newly designed classrooms are different from the traditional ones EXCEPT that _ . | [

mmlu_train_10167 | Before we send humans into deep space, we'll have to find out just how long the human body can survive in a weightless environment. One problem is that in space there's no physical sensation to let you know when you're upside down and astronauts have to rely on possible clues from their surroundings. A few hours after reaching orbit , one in three of all astronauts will experience space sickness--a feeling rather like carsickness. There is also the problem of protection from the extreme hazards of space such as constant meteorite bombardment and radiation. It is going to take some clever technology to keep rockets and astronauts from these dangers. Even with a well-protected spaceship, space travel isn't going to be easy. No matter what you travel in, it is going to be a long flight in space! Science fiction writers often imagine using suspended animation , a kind of forced long-term sleep, as a way for astronauts to escape the boredom of long missions. An even stronger measure might be to freeze the astronauts. We already use cryogenic techniques to preserve dead bodies and store human embryos . Freezing living adults may not be so far away, but perhaps we don't have to do that. Perhaps we should use our existing technology and send frozen embryos to the far corners of universe. Hundreds of years from now, billions and billions of miles away, the embryos will be thawed and their hearts will start beating. These astronauts of the future will not grow inside a mother's body but will be produced in a machine. They will be brought up by robot. It may seem strange but one day it might just happen. We can learn from the passage that _ . | [

mmlu_train_38896 | Scientists warn today that the Atlantic bluefin tuna faces disappearance unless certain action is taken. They used electronic ways to track the movement of the powerful fish from the Gulf of Mexico to the Mediterranean, and report today in the journal Nature that meals of sushi and sandwiches with tuna worldwide are more dangerous than anyone has imagined. The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A good one can fetch as much as PS 52,000 in the Tokyo fish markets. "In my lifetime, we've brought this big fish to the doorstep of death in the western Atlantic Ocean," said Barbara Block of Stanford University in California. "The electronic way of tracks provides the best scientific information we've ever had to manage these tuna and we must, as an international community, start to act actively to make sure of the future of this fish. " Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore in search of deep ocean fish. Tuna--in the Mediterranean and Japan--have been under increasing pressure for years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since 1969.There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger, eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000 in the east, no one knew whether the limits worked. So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water temperatures. "There are two ways to save the Atlantic bluefin tuna--protect them in their production grounds and in their feeding grounds," Prof. Block said. "This will need immediate action in both the central Atlantic, to reduce the loss of the big fish while hunting, and in the Gulf of Mexico and Mediterranean, where tuna produce as separate populations. " According to Professor Block, tuna can be saved by _ . | [

The winner received a computer and a scholarship for a college education. More than 1,500students from across the country entered projects in the competition this year. Their research included chemistry, medicine, physics, mathematics, engineering, and computer science-almost every area of science. Forty students were invited to Washington, D.C. for the final judging. A group of scientists judged them on their research abilities, critical thinking skills and creativity. The judges also questioned the students about scientific problems before deciding on the winners. The top winner received 100,000 dollars for college. Shannon Babb of American Fork High School studied the water quality of tile Spanish Fork River in Utah for six years. She found that people have a harmful effect on the river through human activity, including agriculture. And she suggested ways to improve the water quality in the future. These include educating the public not to put household chemicals down the drains , which lead to the river eventually. Seventeen-year-old Yi Sun of the Hanker School in San Jose, California, earned the second place. He won a 75,000-dollar scholarship for new discoveries about a mathematical theory known as random walks. His work could help computer scientists and chemists. Yi Sun was born in China.

mmlu_train_86918 | People are so busy these days that many people have no time to cook. This becomes a problem, because most families love home cooking. The food tastes good and warm, and a family meal brings everyone together. In some families, meals are often the only times everyone sees one another at the same time. Another reason people enjoy home cooking is that it is often a way of showing love. A parent who makes some cookies is not just satisfying a child's sweet tooth. She or he is sending a message. The message says, " I care about you enough to send an hour making cookies that you will eat up in 15 minutes if I let you." There is also something about the smell of home cooking.

Other studies have also warned about the dangers of overfishing and the effects on ocean environments . But not everyone thinks the oceans are likely to be empty in fifty tears . Some scientists said parts of the world do have problems , but others are doing a good job of protecting fish populations . Government officals in several countries with large fishing industries also questioned the research . The study appeared earlier this month in Science magazine . The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems . These complex systems help control water quality . The scientists say the loss of different kinds of sea life appeared to increase the f fish kills and beach closures from harmful algae growth .

mmlu_train_51318 | If you experience great stress in your life on a frequent basis, you're not alone. Nowadays, stress is almost a given fact of life. Actually, a certain degree of stress can have positive effects on us. But if stress continues over a long period of time, the effects on the body can be harmful, resulting in health problems and stress-related illness, including heart attack and stroke. Stress is a normal reaction by the body to what it perceives as a threatening situation or environment. Short-term reactions may include an increase in heart rate as well as a rise in blood pressure. A person under short-term stress may feel nervous, anxious and even experience shortness of breath. Other reactions can include a dry mouth, quick heartbeat, sweating, stomach upset and diarrhea. When stress is long-term and becomes more chronic in nature, it can cause more serious health-related problems, including regular headaches, back pain, weight changes, sleep difficulties, changes in mood and so on. Chronic stress can also result in memory problems, including difficulty remembering new information and the inability to quickly deal with old information. No matter how your body reacts to stress, ignoring the problem can have serious health results. Not surprisingly, more women than men openly seek the help of their family doctors or other health care experts when they are experiencing stress or stress-related illness. Men are more likely to refuse to admit the problem or attempt to self-treat it, which may contribute to higher rate of drug and alcohol addiction seen in men exposed to chronic stress. There's no doubt that stress is a fact of life and is likely to remain a part of our fast-paced society. Although stress can't be completely _ , methods of dealing with stress-related issues, in my view, can be developed so that the effects of stress on the body are avoided, so people won't be so easy to suffer stress-related illness.

mmlu_train_26089 | In the early days of the Internet, the idea that it represented an entirely new and separate field distinct from the real world was seized upon by both supporters and critics of the new technology.Supporters liked the idea that the virtual world was a placeless datasphere, liberated from constraints and restrictions of the real world, and an opportunity for a fresh start.For instance, John Perry Barlow, an internet activist, issued the "Declaration of the Independence of Cyberspace" in February 1996.He thundered, "Governments of the industrial world, I come from cyberspace, the new home of mind.Cyberspace does not lie within your borders.We are creating a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth. Where Mr.Barlow found the separation between the real and virtual worlds exciting, however, critics regarded it as a cause for concern.They worried that people were spending too much time online, communicating with people they had never even met in person in chat rooms, virtual game worlds and, more recently, on social - networking sites such as MySpace and Facebook.A study carried out by the Stanford Institute for the Quantitative Study of Society in 2000, for example, found that heavy internet users spent less time talking to friends and family, and warned that the Internet could be "the ultimate isolating( ) technology". Both groups were wrong, of course.The Internet has not turned out to be a thing apart.Unpleasant aspects of the real world, such as taxes, crime and cheating are now characteristics of the virtual world, too.C'amers who make real money selling swords, gold and other things in virtual game worlds may now find that the tax man wants to know about it.Designers of virtual objects in Second Life, an online virtual world, are seeking to real -world lawsuits in order to protect their intellectual property. At the same time, however, some of the most exciting uses of the Internet rely on combining it with the real world.Social networking allows people to stay in touch with their friends online, and plan social activities in the real world.The distinction between online and offline chatters does not matter any more. All these approaches treat the Internet as an extension or an attachment to the physical world, not a separate space.Rather than seeing the real and virtual fields as distinct and conflicting, in short, it makes sense to see them as complementary and connected.

mmlu_train_54016 | Is there anything the latest cell phone can't do? It can record movies, surf the net, and download the newest MP3 songs, but don't let those fancy features fool you. After all, chances are that phones have a Global Positioning System (GPS) chip. GPS lets phone companies determine the location of your phone at all times. If you are hurt and call 911, rescuers can find you by using your phone's GPS. But emergency officials aren't the only people interested in knowing where you are. Several new companies are using cell phones with GPS to monitor teen drivers for _ parents. The programs vary, but most of them allow parents to use the Internet to monitor their kids' locations, driving habits and speed. Some programs even let parents set speed and location limits so that they are alerted if their kids drive too fast or go beyond a predetermined boundary. Supporters of monitoring say that the programs also help if a teen is kidnapped or lost. Andrea Gutierrez uses a driving program to help her daughter get home. "I give her directions by looking at an online map, which shows me where she is". Jean Nichols, 17, says that parents are forgetting one very important thing: trust. "I don't like the idea of someone using a device that keeps tabs on me." Others say the information could be misused. "If everyone can find out exactly where your 17-year-old girl is at all times, it will present a potentially dangerous problem," Hohn Lawford told the Ottawa Citizen. Alana Watenpuhl, 19, says that teens can easily outsmart the programs. "Teens can always leave their cell phones somewhere and then go out with their friends. It's not likely that the chips are attached to their bodies," she told reporters. "But who knows?" she added. "That might be what's coming next." What is the text mainly about? | [

mmlu_train_64644 | Zuhur Yasin has never been to the US, but she holds a bachelor's degree from an American university. Part of Yasin's studies in Somaliland were spent in a special classroom, lined with rows of computers equipped with webcams and microphones. The 29-year-old watched videos and took part in live virtual classes at Indiana University as part of her journalism programme at the University of Hargeisa."We had discussions and shared any challenges or questions," she says. The African Virtual University(AVU), an intergovernmental organization, connected Yasin with Indiana University. The AVU says it has used virtual learning to train 43, 000 students since its creation in 1997. Professors use programmes and apps including Skype and WhatsApp to communicate with students, but classes are taught using special software. The AVU is considering plans to make lectures accessible on mobile phones. Like Yasin, many students in sub-Saharan Africa are looking for opportunities to attend university. In 2008, the region had the lowest university attendance in the world, with just 6% of secondary school-leavers advancing to higher education, according to the UN's Educational, Scientific and Cultural Organization. In May, the African Union(AU) opened the e-Learning Africa Conference on ICT for development, education and training at its headquarters in Addis Ababa. Rebecca Stromeyer, the founder of e-Learning Africa, says, "Now it is the time when technology can really help to protect the progress many African countries have made in education. If the right decisions are made now, they will help to achieve long-term economic growth." Experts say online learning tools can connect African students to massive open online courses (Mooc,) such as Coursera, an education platform that provides free virtual education from some of the world's top universities.

mmlu_train_73198 | Bears are found in Asia, Africa and America. They are very strong, with short tails and thick legs. Bears eat almost everything. They seem to enjoy meat, vegetables, fruit, milk and rice. Bears are not quite dangerous as people imagine them to be. Like most animals, they will try to stay away from human beings. However, bears are not weak animals. Sometimes they kill hunters, for they can be very dangerous. Bears have a good sense of smell but they have poor eyesight. They are also hard of hearing but they are very clever. They feed mainly on roots, frogs, fish and also small insects. They will sometimes kill deer and other large animals, but they seem to like small animals better. In the cold area, bears hibernate, or go to sleep from October to April. Before they start to hibernate, they eat a lot and store fat. The mother bear has its babies, usually two, towards the end of hibernation. A large bear is much cleverer than a cat and most other animals. You may notice at the zoo how cleverly they ask for food. They sit up and hold out their paws.

mmlu_train_9061 | After the Summer Olympics are over, when all the athletes have gone home and the television audience has switched off, another group of athletes and fans will arrive at the host city, and another competition will begin. These are the Paralympics, the games for athletes with a disability. But in Beijing in 2008, for the first time, one of the greatest Paralympics athletes did not take part. She is a British athlete by the name of Tanni Grey-Thormpson. Born with spine hifida which left her paralysed from the waist. Tanni used a wheelchair from the age of 7. at first, she did not like sports, apart from horse-riding, which gave her a sense of freedom. But in her teens, she started taking sports more seriously. She tried swimming, basketball and tennis. Eventually she found she began to love athletics, and never looked back. Indeed, Tanni's athletic career took off . In 1984, when she was 15, she pulled off a surprise victory in the 100metres at the Junior National Wheelchair Games. In 1988, Tanni went to her first Paralympic Games in Seoul. She won bronze in the 400 metres. Even greater success followed at the 1992 Barcelonn. Paralympics. Tanni won gold in the 100, 200, 400 and 800 metres relay, setting two world records in the process. In the same year she achieved the first of her six London Wheelchair Marathon victories. Tanni's success had been part motivation , part preparation, "The training I do that enables me to be a good sprinter enables me to be good at a marathon too. I train 50 weeks of the year and that keeps me prepared for whatever distance I want to see.... I am still competing at a very high level, but as I get older, things get harder and I want to retire before I fall apart." Indeed Tanni retired finally after the Visa Paralympic World Cup in 2007. Her wish is to coach young athletes for Beijing 2008 Olympic Games. In spite of ups and downs, she never takes her fate lying down. In her splendid life, she has won an amazing eleven gold medals, four silvers and one bronze in series of Paralympics- a top level athletic career covering two decades. She has won the London Wheelchair Marathon six times, more than any other competitor, and she has set over thirty world records. What advice does she have for young athletes? "Work hard at your studies, and then train, train and train again." When did Tanni win her first Olympic gold medal? | [

They find out what plants are used in healing. Then they look at what the plant contains. They find the active ingredient , which is the chemical in the plant that works to heal. Many of the drugs we use, including aspirin, have come from these natural medicines. In recent years, many people in the US have taking what are legally known as dietary supplements . They may be vitamins or minerals. They may be herbs that help with health problems, such as depression. Some of them are teas. Others are capsules or tablets. They are sold in natural food stores, drug stores, and groceries. Most people think that because these products are natural they are also safe. This is not always true. There are many plants that are poisonous. There are others that have bad side effects. The New England Journal of Medicine publishes medical research. A recent edition called for the government to _ dietary supplements. Several doctors wrote to the Journal and told of bad experiences people have had with dietary supplements. Dietary supplements aren't tested in the same way as drugs. There is not always proof that the supplement really does what it is supposed to do. There is also a problem with purity of the supplements. Supplements have been found to contain things that are bad for the body.

mmlu_train_65826 | The Lionfish Invasion! Lionfish are popular saltwater aquarium fish all over the world, especially in the United States. Nowadays, they also live in Atlantic waters off the East Coast of the United States. These lionfish are what scientists call an invasive species or an "alien invader." Local divers off the coast of North Carolina were not expecting to see what they found one day in August 2002--the beautiful lionfish, common to the warm waters of the western Pacific, but unknown of the Carolina coast. They provided the first solid evidence that lionfish were in the Atlantic. A year later, scientists documented 19 lionfish sightings at eight locations along the North Carolina continental shelf. Then, lionfish were observed off the coasts of Florida, Georgia, and South Carolina, and even as far north as Long Island, New York! Between 2000 and 2003, lionfish sightings were reported at 16 different shipwrecks and natural hard bottom locations. During a summer 2004 research expedition, NOAA(The National Oceanic and Atmospheric Administration) scientists collected 155 lionfish at 19 different locations off the North Carolina coast alone. The jump in numbers and distributions over such a short time strongly indicates that the lionfish is reproducing in the Atlantic Ocean. If this is true, it's the first time that a western Pacific fish has populated the U.S. Atlantic coast. These lionfish were likely released on purpose when people no longer wanted them! The swift and warm Gulf Stream, which transported the floating lionfish eggs from Florida northward, helped the lionfish's Atlantic journey. In Florida waters and along the continental shelf near the Gulf Stream the temperatures are very similar to the lionfish's native waters. However, from north Florida upward, the waters along the coastline are too cold in the winter for lionfish to survive. Scientists expect them to survive the winter only at water depths greater than 120ft because this is where the Gulf Stream has influence all year long. Very importantly, the types of predators and competitors present in the Atlantic are very different from the native range of the lionfish. Generally, the lionfish have not been found to endanger marine ecosystems because they were not likely to survive long. Scientists call the lionfish an "alien invader" because the lionfish _ . | [

mmlu_train_63275 | How could we have thought so wrongly of as banana peel that it always hits the garbage? Utility of anything seems to be in the eyes of the beholder. The banana peel hasn't been an exception. What most of us looked at as waste was converted to a thing of utility by Prithwis Mukhopadlyay, a 14-year-old prodigy. This Bengali boy, nourished in the US, Lake Junior High in Woodbury, Minnesota, has come up with an idea to convert banana peels to biogas. . It's well known that almost any organic waste can be converted to biogas. But why biogas from banana peel has hit the news is because it produced five times as much biogas as manure , a commonly used source for producing biogas, in the experiments Prithwis conducted. He filled two airtight containers, one with manure and the other with banana peels. Then he mixed each content with water and connected them to empty jars via pipes to collect the gas produced. He placed a heater next to each jar and measured the gas collected for 60 days. His studies proved that banana peels produced five times more biogas than manure. This project titled 'Comparison analysis: Eco-friendly source of energy for the future,' earned him a spot in Discovery Channel Young Scientist Challenge. This weekend, the young whiz is to showcase his research work along with 40 other finalists at Washington. "Initially, I thought of doing a project that would reduce global warming. Things changed after I visited a biogas plant in a village in India during my summer vacations. It was an amazing experience," Prithwis says. This article probably appeared in a _ magazine. | [

Many of the animals have been destroyed by the very cold winters recently and by changes in the plant life there. When the deer can't find enough food, they die. If the wolves continue to kill large numbers of deer, the deer will disappear some day. And the wolves will, too. So we must change the life cycles there.

Some birds like eating locusts , but birds cannot easily catch them. Why? It is because locusts change their color1s together with the change of the color1s of crops . When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color1 as crops have. Some other pests with different color1s from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night. If you study the animal life, you'll find the main use of color1ing is to protect the animals themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters . This is because they have the color1s much like the trees'. Have you ever noticed an even stranger act?

The charity Alcohol Concern is running a campaign of restriction by encouraging people to have a dry January.

The study by the University of Sussex followed up nearly 900 participants in Alcohol Concern's Dry January campaign and found out that 72%of them had kept harmful drinking sessions down and 4%were still not drinking. Moderation seems to be the key to everything.The official recommendation for women is not to regularly drink more than 2 to 3 units of alcohol a day.The limit for men is 3 to 4 units of alcohol--no more than a pint of 5.2%ABV lager,beer or cider.

Robots, such as the sound-sensitive Chapit, answer simple questions and even joke with people to help the _ fight loneliness and stay alert in old age. "Many old people in Japan live alone and have no one to talk to," said Kazuya Kitamura, a representative of the expo organizer. "Communication robots stay together with old people and don't mind listening to the same stories over and over again." While Chapit, a relatively simple robot, managed to attract a partner, many researchers, such as Kiyoshi Matsumoto, a professor at the University of Tokyo, struggle to attract sponsors for more expensive projects. Matsumoto's "Personal Mobility Robot", equipped with four cameras and a sensor to recognize the user's centre of gravity, is designed to help the elderly move around without pressing buttons as in traditional wheelchairs. The robot can also help find misplaced glasses by recognizing them with a sensor. "We have developed a robot that can assist many people, but because of the high cost, we still haven't found a sponsor," said Matsumoto, who added that the cost of the machine, if produced in large quantities, would be comparable to that of a small car. "In the current economic environment there are few companies willing to invest in such a costly project," he said. Other robots, such as the award-winning "DiGRO", can support busy parents who have little time to play with their children. The robot can use the Internet to find a simple image and then draw pictures, looking after children while parents work. Japan is one of the world's fastest-aging countries and the government predicts that by 2050 the population of people over 65 will reach 40 percent. What can Chapit do according to the text? | [

This year, 422,000 fourth graders and 343,000 eighth graders took the exams between January and March. Students were asked to read grade-appropriate materials and answer questions for the reading test. For the math test, students answered questions about geometry, algebra, number properties, measurement and other topics. The U.S Department of Education released the scores in a report called The Nation's Report Card (NAEP). This year, students earned the highest scores ever recorded on the math exam, which has been given since 1990.Fourth graders scored an average of 241.That is a one-point increase from 2009and a 28-point increase from 1990. Eighth graders made similar progress. Then average score this year was 284,up one point from 2009 and 21 points from 1990. In reading, fourth graders scored an average of 221 points, the same average score since 2007.That score is four points above those from 1992, when the first reading test was given.

mmlu_train_37153 | Scientists have discovered a gene that plays a role in violence in men ill-treated in childhood.The discovery could explain why some experience unhappy childhoods and go on to normal lives, while others turn to violence, crime of antisocial deeds. But it will also restart another argument. Terrie Moffitt and Avshalom Caspi report in Science today that one common form of a gene in the brain makes men more likely to be violent--but only if they have experienced cruelty or rejection in childhood . The researchers followed up the life histories of 442 boys born in New Zealand in 1972. Of these, 154 had been ill-treated in the first 10 years, 33 of them badly. They had either experienced sexual attack, beatings or rejection by mother or stepparents. Of the 154 children , 55 had a less active variant of a gene called MAOA, and 99 had the more active variant . The 55 boys were more than twice as likely to have been in trouble as the other ill-treated group . They made up 12% of the total, but were responsible for 44% of all crimes from among the 442 boys. Prof Moffitt thought a "violence" gene had not been discovered. Boys with the less active form who were not ill-treated during childhood lived normal lives. "It is very common in the population. One third of us have it." she said, "So the gene doesn't do much of anything, it doesn't cause any trouble in any way, unless we are also ill -treated". The gene might also show the ability to bear mental stress. The army or the police might examine the applicants to see if they have the more active form . But the discovery also raises the argument that people with the less active form of the gene could be social dangers, to be treated with medicine. "This research can easily lead people to fix social problems through medical treatment," said David King of the UK Gene Alert Group. According to the passage, we can infer that_. | [

mmlu_train_10476 | The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms. After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London. Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London. "The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire. At the peak of the cycle, violent outbursts called coronalmass ejections occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots. Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available. The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares and explosions as they occur. Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advance warning, we'll be able to reduce the damage. _ What does the last sentence mean? | [

The question is, what can they do about it? Some believe exercise can be helpful. But the trouble is that it only makes you want to eat more. You might sweat out a couple of pounds playing tennis or climbing a mountain, but you put it all back on again with a big steak or bread and jam. A helpful way is food choosing. But what sort of food should you choose? Some believe that the less they eat, the slimmer they will be. They don't eat anything until they become weak with hunger. Some stick to milk and bananas. You'll find you need a lot of bananas, and unless you live where they grow, they aren't cheap. Others say that if you eat things like hard-boiled eggs, and apples with their skins on which are hard for your stomach to digest, the more you eat, the thinner you get. This is because you use up the fat in your body to get the energy to digest the food. For most of us these methods are too extreme.

Park Associates, a Dallas-based technology market research firm, said 29 percent of U.S. families, or 31 million homes, do not have Internet access and do not intend to subscribe to an Internet service over the next 12 months. The second annual National Technology Scan conducted by Park found that the main reason why potential customers say they do not subscribe to the Internet is because of the low value to their daily lives rather than concerns over cost. Forty-four percent of these families say they are not interested in anything on the Internet, versus just 22 percent who say they cannot afford a computer or the cost of Internet service, the survey showed. The answer "I'm not sure how to use the Internet" came from 17 percent of participants who do not subscribe. The response "I do all my e-commerce shopping and YouTube-watching at work" was cited by 14 percent of Internet-access refuseniks. Three percent said the Internet doesn't reach their homes. The study found U.S. broadband adoption grew to 52 percent over 2006, up from 42 percent in 2005. Roughly half of new subscribers converted from slower-speed, dial-up Internet access while the other half of families had no prior access. "The industry continues to chip away at the core of non-subscribers, but has a long way to go," said John Barrett, director of research at Parks Associates.

mmlu_train_33572 | BEIJING -- Rising smartphone star Xiaomi is moving upmarket and taking aim at Apple's iPhone. The Chinese maker known for low-priced phones on Thursday unveiled a new model that Chairman J un Lei said is comparable to Apple's iPhone 6 but thinner, lighter and much cheaper. The phone starts at 2, 299 yuan ($375), less than half the 5,288 yuan ($ 865) price of an iPhone 6 in China. Xiaomi, founded in 2010, passed South Korea's SaM:ung Electronics Co. in the second quarter of last year as the best-selling smartphone brand in China by number of phones sold. The company is expanding into India and other developing markets but has yet to announce plans to enter the United States or Europe. Xiaomi "is a respected brand that already has an Apple-like following" in China, said analyst Brian Blair, who tracks mobile device makers at Rosenblatt Securities. Apple is still a relatively small player in China, selling about 45 million iPhones there last year, Blair estimates, but will continue to grow. "Apple is very much a premium brand," said Blair. "The company that's more at risk is SaM:ung, which has been losing share in that market." Privately held Xiaomi said last year's sales tripled to 61. 1 million phones and revenue more than doubled to 74. 3 billion yuan ($12.2 billion). The company, based in Beijing, recently completed a round of fundraising from investors that it said valued Xiaomi at $ 45 billion, making it one of the world's most valuable technology brands. Xiaomi ran into legal trouble in India in December after a court blocked sales while it hears a complaint by Sweden's LM Ericcson that the Chinese company violated its patents. In a blog post earlier this month, Lei called the case a "rite of passage" for a young company. Which of the following statements is true? | [

mmlu_train_67817 | In some science fiction movies, evil robots refuse to die, no matter how hard people fight back. Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs. Until now, even the most advanced robot was almost certain to break down when it was damaged . That is because its computer inside simply doesn't know how to make the machine work after its shape has changed. To deal with this problem, the scientists put eight motors and two sensors that read how the machine is working. They all give signals to the machine's software. Using this information, the computer can then figure out the machine's shape at any moment. The new technology is a big advance in robot-making, scientists say, and it's far from scary. It may someday help scientists create better artificial arms and legs and give new freedom to people who lose _ . It might also help scientists understand how people and animals figure out their own sense of place in space.

Poison has long been an important part in literature and history, and it seems to always be about evil, danger and death. But how much do you really know about poison? An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison. The exhibition will continue until Feb. 2016, reported The New York Times. The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars, frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered in a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans. The exhibition also features interactive activities. In an iPad-based game, visitors are presented with three puzzling illnesses and asked to identify the poisons based on symptoms. In one case, for example, a pet dog is found sick in a backyard and visitors have to figure out whether it was the toad , the leaky batteries in the trash or the dirty pond water that did it. "Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others." This is what visitors learn from the last part of the exhibition, which displays how poisons can be used favorably by humans, including for medical treatment. The blood toxins of vampire bats, for example, can prevent blood from clotting , which may protect against strokes. A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol. One chemical in the venom of Gila monsters can lower the blood sugar of its victims, so it has been used to treat diabetes.

mmlu_train_66374 | NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares. Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly wipe out, the effect of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are wiped out. They are not sure to what degree people's memories are affected. The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories. "Some memories can ruin people's lives. They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering." But those who are against the research say that maybe the pills can change people's memories and changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past. "All of us can think of bad events in our lives that were terrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist. The passage is mainly about _ . | [

mmlu_train_39518 | According to a survey,more Europeans go digitalchanging from fixed lines to mobile phones and from narrowband to broadband Internet connections. The survey showed that 22 percent of EU households use only mobile phones, up from I8 percent a year ago,while the percentage of households with at least one fixed line decreased by 5 percent to 72 percent, although the percentage of households with at least one mobile phone remains fairly stable at 8l per cent. Broadband is presenting a rapid upward trend in the EU, showed the survey, which polled(...)27,000 households across the union. 'Itventy-eight percent of households are now connected to the Internet via high-speed "broadband" links, up six percent from last year, while narrowband usage has dipped by three percentage points to 12 percent. More than half of households access the Internet via an ADSL line and 34 percent of broadband connections are wireless. "Europe's digital economy is growing strongly as more and more households love to choose between fixed, mobile and Internet services," said EU Information Society and Media Commissioner wiane Reding. "The challenge of this year's reform of the EU's telecom rules will be to respond to this rapidly changing technological environment while enhancing at the same time effective competition:' Meanwhile, nearly 20 percent of Europeans buy two or more telecom products from a single service provider, the combination of fixed telephony and.Internet access being the most common. The result may strengthen the commission's case for breaking up telecom giants, whose control over the fixed line networks~accused of hindering competition."Today's survey findings will feed into the ongoing public debate on the reform of the EU telecom rules, planned for summer this year," said Reding.

mmlu_train_25392 | French surgeons have performed what they said on Wednesday was the world's first partial face transplant--- giving a new nose, chin and lips to a woman attacked by a dog. Specialists from two French hospitals carried out the operation on a 38-year-old woman on Sunday in the northern city of Amiens by taking the face from a brain-dead woman, who had hanged herself just hours before the operation. Her family agreed on the operation. "The patient is in an excellent state and the transplant looks normal," the hospitals said in a brief statement after waiting three days to announce the pioneering surgery. The woman had been left without a nose and lips after the dog attacked her last May, and was unable to talk or chew properly. Such injuries are "extremely difficult, if not impossible" to repair using normal surgical techniques, the statement said. The statement did not say what the woman would look like when she had fully recovered, but medical experts said she was unlikely to _ the woman who had been the source of her new face. The operation was led by Jean-Michel Dubernard, a specialist from a hospital in Lyon who has also carried out hand transplants, Skin transplants have long been used to treat burns and other injuries, but operations around the mouth and nose have been considered very difficult because of the area's high sensitivity to foreign tissue. Teams in France, the United States and Britain had been developing techniques to make face transplants a reality There was a short-term risk for the patient if blood vessels became blocked, a medium-term danger of her body rejecting the new skin and a long-term possibility that the drugs used could cause cancers. Experts say that although such medical advances should be celebrated, the transplant had thrown up moral and ethical issues. Little is known about the psychological effect of the transplant.
