mmlu_train_14087 | American officials have sharply reduced their expecmtions for this year's corn and soybean crops.Farmers in the Midwest are struggling with record heat and the worst drought in many years. The United States is the world's largest producer of com and soybeans.Last Friday the Agriculture Department predicted corn production would add up to 10.8 billion bushels this year.That was down 17%from a prediction made just a month ago.And it was down 13%from last year's level.The average yield per hectare could be the lowest in seventeen years. At the sarne time,the government predicted that soybean production would be 12% lower than last year. The price of corn has hit record levels.Corn is a major part of animal feed,so the price of meat,milk and eggs is also expected to climb. The FAO says average food prices worldwide rose 6%in July.The American drought was a big reason. The situation has renewed the fight between food and fuel.About 40%of the nation's corn crop goes into making ethanol .The production process leaves some of that in a form that can be fed to animals.Still,at least one-fourth of the American corn crop is now made into fuel. The United States requires that part of its corn crop be used in the production of biofuels .The use of ethanol has grown as government requirements have increased.But Jose,the head of the FAO called for"an immediate,temporary pause"of that requirement.He said more of the American corn production could then be used as food or to feed animals. The American livestock industry is also urging Congress to stop the law that requires ethanol in gasoline.But corn farmer Alan Bennett says doing that would hurt his town. A 2005 law requires automobile fuel to contain ethanol.The growth of the ethanol industry and competition for corn has been helping parts of rural America that had been reducing for years. Why did average food prices worldwide rise 6%in July? | [
"Because the price of corn crop has got to the top of history.",
"Because much of the corn crop in the world goes into making ethanol.",
"Because America is suffering the worst drought.",
"Because most of the corn has been fed to animals."

mmlu_train_16975 | Jeanne Calment, a French woman, became a record breaker on 17 October of 1995, when at the age of 120 years and 238 days, she became the longest-lived human being on record. A Japanese man died in 1986 at the age of 120 years and 237 days. Jeanne Calment lives in a small old people's home in the south of France; her husband, her only child and her grandson have all died. She is nearly blind and deaf and is always in a wheelchair, but her doctor describes her as being more like a 90-year-old in good health than someone of 120. She still has a lively sense of humor. When asked on her 120th birthday what she expected of the future, she replied: A very short one. She also remarked that she thought the good Lord had forgotten all about her. So what is the key to a long life? According to some doctors, diet, exercise and no smoking are the three important factors. Jeanne Calment has followed two of the tips . She has always eaten a healthy diet, and she used to do exercises every day until she broke her leg at the age of 115. However, until recently she drank two glassed of strong red wine a day, and she does smoke (now only a little). Besides, Jeanne Calment might have got very good genes from her parents. Her father lived to the age of 94 and her mother to 86. A local lawyer bought her house when she was 80 under an agreement that he would pay her some money every year until her death. It must have seemed a good move at the time, but so far the lawyer has paid her at least three times the value of the house. Every year on her birthday Jeanne Calment sends him a card saying: Sorry, I'm still alive! Jeanne Calment owes her good health and long life to _ . | [

mmlu_train_56092 | People who enjoy a dream-filled sleep are better at recalling information and making links between facts when they wake, scientists found. But recharging with a shallow nap offers no such mental improvement, the research suggests. The results of the study add to the evidence that Rapid Eye Movement (REM) sleep is very important to the brain's ability to strengthen memories. An average night's sleep includes four or five periods of REM sleep, but these tend to be longer towards the end of the night. This means that adults who get less than the recommended seven to eight hours a night -- and therefore inadequate REM sleep -- may be damaging their mind's ability to form strong memories. Although REM sleep is not classified as a type of deep sleep, it is only reached after the brain has passed through deep sleep stages. In the most recent study, participants were shown groups of three words -- such as "cookie", "heart", and "sixteen" -- and asked to find another word that can be associated with all three words. In this example, the answer would have been "sweet". They were tested once in the morning and then given the same task again in the afternoon. In between, some were allowed a nap with REM sleep, some a nap without REM sleep, while the others had a quiet rest period. The quiet rest and non-REM sleep groups showed no improvement in their test results, but the REM sleep group improved on their morning performance by an average of almost 40 percent. Dr Sara Mednick, a sleep researcher at the University of California who led the study, believes the formation of connections between previously unassociated information in the brain -- which leads to creative problem-solving -- is encouraged by mental changes which occur during REM sleep. People woken while their closed eyes made rapid movements recalled much more color1ful and detailed dreams than people woken during other stages of sleep. What is the author's purpose in writing the passage? | [

mmlu_train_13915 | Thank you for agreeing to be a Test Administrator for PISA. The purpose of this manual is to help you to understand how you will assist with the successful implementation of this large-scale student survey. 1.1. What is PISA? PISA stands for the Programme for International Student Assessment, sponsored by the Organisation for Economic Co-operation and Development (OECD). PISA 2015 is the sixth PISA study that has been conducted since 2000 and involves more than 70 participating countries. PISA has the following characteristics: * It is the world's largest international survey in education. * It surveys students aged about 15 years. * It assesses students' preparedness for adult life. Undertaking PISA is important because the results of the test can be used: * to indicate how well prepared students in a country/economy are for learning once they leave school; * to identify areas for improvement over time by schools, education systems, and governments; and * to allow a comparison of student performance and the learning environment between different countries. 1.2. Components of PISA 2015 * 1.2.1. Cognitive test 42 students from each school will be randomly sampled to complete a 2-hour computer-based test consisting of questions in science, mathematics, reading, and Collaborative Problem Solving. * 1.2.2. Questionnaires These students will also be asked to complete a 30 minutes Student Questionnaire on the computer either directly after the test sections or at a later time. * 1.2.3. Financial Literacy assessment After the cognitive test and questionnaires, a sub-sample of 10-11 students will take a computer-based Financial Literacy(FL) assessment. The 65-minute Financial Literacy assessment tests students' knowledge of personal finances and their ability to apply it to their financial problems. What can we know about PISA from the passage? | [

mmlu_train_27932 | The accident at Lake Sherwood was in our backyard. An SUV had gone off the road,down a hill, and collided with a tree. When we heard the wreck, I remembered to say "call 911". My family was the first on the scene. Nick, my son, was on the cell phone with 911. He saw a friend who was a victim in the crash who was a 15 years old girl who was badly disfigured and had died instantly. It was a terrible scene. There had been six people in the truck, all between 15 and 17 years old. My husband and I checked all the victims, and I picked one who was conscious and stayed with him. I talked with him and had him lay on the ground. When I asked him if he was hurt, he said he was sore all over. When help arrived, they asked me to stay and continue working with them. I did as Debbie Romine, .my instructor, said in class, and did what they wanted. They even said thank you before they left. The sheriff deputies came by Saturday night to get our statements and play the 911 tape back, so Nick could identify all the voices in the background. They said over and over that the way he handled the call was the best they had heard in a long time. He was calm and worked with them even when he saw his friend who had died. The Sheriff's Department is sending some people over to help us work through our emotions. The first aid and CPR course I took in January really helped me.

In the past six months alone, the site has won a Webby (the online version of the Oscar) for technical excellence, sets a new record for search engines by indexing a billion Web pages. Yahoo still has 10 times the audience, but Google consistently ranks first in customer satisfaction: 97% of users find what they're looking for most or all of the time."You see people smile when they use it, like they've found something no one else knows about," says Danny Sullivan, editor of an online newsletter.

mmlu_train_26766 | 40 years ago the idea of disabled people doing sport was never heard of. But when the yearly games for the disabled were started at Stoke Mandeville, England in 1948 by Sir Ludwig Guttmann, the situation began to change. Sir Ludwig Guttmann, who had been driven to England in 1939 from Nazi Germany, had been asked by the British government to set up an injuries center at Stoke Mandeville Hospital near London, His ideas about treating injuries included sport for the disabled. In the first games just two teams of injured soldiers took part .The next year, 1949, five teams took part. From those beginnings, things have developed fast. Teams now come from abroad to Stoke Mandeville every year. In 1990 the first Olympics for the disabled were held in Rome, in the same place as the normal Olympic Games. Now, every four years the Olympic Games for the disabled are held, if possible, in the same place as the normal Olympic Games, although they are organized separately. In other years games for the disabled are still held at Stoke Mandeville, In the 1984 Wheelchair Olympic Games, 1,064 wheelchair athletes form about 40 countries took part. Unfortunately, they were held at Stoke Mandeville and not in Los Angeles, along with the other Olympics. The games have been a great success in helping the progress of international friendship and understanding, and in proving that being disabled does not mean you can't enjoy sport. One small source of disappointment for those who organize and take part in the games, however, has been the unwillingness of the International Olympic Committee to include disabled events at the Olympic Games for the able-bodied. Perhaps a few more years are still needed to persuade those fortunate enough not to be disabled that their disabled fellow athletes should be included. What do we know about Sir Ludwig Guttmann from the passage? | [

mmlu_train_81505 | Smartphone, poor sight Look around and you will see people busy on their smatrphones . Smartphones do make our lives easier. But have you ever thought about what they mean to your eyes? According to a study, half of the British people own smartphones and they spend an average ( ) of two hours a day using them. There has been a 35% increase in the number of people in the U.K who suffer from short-sightedness since smartphones were introduced there in 1997. Staring at smartphones for a long time gives you dry eyes. When looking at something in the distance, your eyes automatically blink a certain number of times. However, when you look at the things closer to your face, the blink slows down. This reduces the amount of tears and causes discomfort in your eyes. Another bad habit is using smartphone in dark rooms before going to sleep. If you look at a bright screen while your pupils become larger, too much light goes into your eyes. This can be bad for your eyes and causes a disease called glaucoma . Maybe it is possible for you to stop using your smartphone, but there are a few things you can do to protect your eyes. * Hold your phone at least 30 centimeters away from your eyes when using it. *Take a break every hour and try the following: look at something at least 5 meters away from you and then focus on your nose.

mmlu_train_36244 | Miya volunteered abroad in Costa Rica with World Endeavors assisting at an orphanage and teaching English at a school. As a freshman at Yale University, Miya had plans to go to medical school.Knowing that her next two summers would be occupied doing research, Miya decided to go abroad the summer after her freshman year."I wanted to improve my command of the Spanish language and learn about the culture and history of another country," she explained.In the summer of 2014, Miya volunteered for six weeks in the World Endeavors program in Atenas, Costa Rica, working in an orphanage and teaching English to children in grades one through six. "A long time before I left, I had positive expectations for the trip," said Miya.But as the date grew closer she found herself getting more and more nervous."I thought, what if my host family doesn't like me? What if I get sick?" Her fears, as fears often are, turned out to be unfounded."The people were so supportive and loving," said Miya."I felt like I was part of the family." Miya's host family had a large network of cousins who all lived within shouting distance. The family would cook together, and at night would go dancing, talk or eat ice cream.She noted that the World Endeavors staff on location--Diego and Mercedes, and Mercedes' husband and daughter -were particularly helpful, taking her right to her neighborhood from the airport, and checking up periodically to make sure everything was going well. While her nights were spent dancing, cooking, and talking with her host family, Miya's days were occupied with the children of her host city."I would teach in the morning, and work in the orphanage in the afternoon," said Miya, whose placements were within walking distance from her host family.While the children were a lot of work, Miya felt a strong connection to the kids in the orphanage. Miya noted that Costa Rica is one of the more developed countries in Central America. A nearby Internet cafe, for example, helped her to stay in touch with her family while she was away.And now, back in the United States, the Internet helps her keep in touch with her host family.Their correspondence continues in Spanish.And her host parents, Rosario and Jorge, recently sent Miya a Christmas card through the mail. Back at school, Miya continues to pursue her instinct to improve education through volunteering. She participates in a mentoring group and works on a community health education program for high school students.Her time in Costa Rica, she says, "fits right into my interests in global health."

All colors have special power. Scientists have found that many colors have specific effects on people's mind and feelings. Try an easy and interesting experiment and you'll see how color " _ " you sometimes. Wrap two boxes of the same size with colored paper, one red and the other white. Then weigh the two boxes with your hands. Which one is heavier? Most people will think that the red box is heavier, even though they weigh the same. Colors can affect learning. Scientists have found that students spend more time reading if they read information written in blue text. Blue helps most people calm down and think more. Clever uses of colors in daily life are to be seen everywhere. Hospitals and libraries seldom paint their walls, tables and desks red. They use light colors, like light blue or green. Red makes people excited while light colors help them relax. Haven't worked out how color affects your daily life? Start with your small room.

In the southwest African country of Namibia,and the Sahara lands of Mall further north,the desert elephant _ . Although not regarded as a separate species from the African elephant,the desert cousin differs in many ways.Their bodies are smaller,to absorb less heat,and their feet are larger for easier walking across sandy surfaces.They are taller,to reach higher branches.They have shortertusks ,and most importantly,longer trunks to dig for water in riverbeds. Desert elephants can travel over 70 kilometers in search for feeding grounds and water-holes,and have a larger group of families.They drink only every 3-4 days,and can store water in a "bag" at the back of their throat,which is only used when badly needed.Desert elephants are careful feeders--they seldom root up trees and break fewer branches,and thus maintain what little food sources are available.Young elephants may even eat thedung of the female leader of a group when facing food shortage. During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly.Desert elephants have sand baths,sometimes adding their ownurine to make them muddy!

mmlu_train_10933 | Death rates for heart disease in Britain have dropped by more than 40 percent in a decade,UK scientists will report today. Wide uptake of cholesterol--busting statin drugs ,healthier lifestyles and better medical practices have seen a huge reduction in deaths caused by heart attacks,stroke and other cardiovascular problems. However,heart disease remains Britain's biggest killer. The new study,by experts at Oxford University,shows there has been a 44.4 percent drop in death rates among men in the UK and a 43.6 percent drop among women linked to heart problems in the ten years to 2011. The team compared death rate associated with cardiovascular disease across Europe.They found that Britain has one of the best records in Europe,with 342 deaths as a result of heart disease per 100,000 men in 2011,and 232 per 100,000 women. Some nations-including Ukraine,Macedonia and Moldova--see more than 1,000 heart deaths per 100,000 of the population. Overall,heart disease causes 45 percent of all deaths across Europe,but only 27 percent in the UK.The study,led by Dr Nick Townsend,showed that cardiovascular disease is mainly a disease of old age. But researchers said that across Europe _ still causes more than 1.4million deaths in those aged under 75 and nearly 700,000 deaths in under 65s.Dr Townsend said:'Cardiovascular disease results in 49 percent of deaths among women and 41 per cent among men.'

Its students have won praise not only for doing this research but also for presenting their findings to groups of expert scientists. The school is one of the Super Science High Schools allowed by the Ministry of Education, Culture, Sports, Science, and Technology, where students are given an opportunity to study science at an advanced level. Here, students use the same type of hitech experimental laboratories as those found at universities. In these labs, they conduct experiments and research in new fields of study not found in textbooks. As part of this science course, the students, with the help of Hiroshima University, used a machine called sequencer , and over the course of a year and a half they succeeded in decoding the DNA. They then presented their results to academic groups. Achieving a world first might sound very wonderful, but the process of decoding the DNA involved very hard work. The students were also responsible for maintaining the equipment, and they had to read difficult research papers and put in extra study beyond their regular schoolwork. "Researchers need to work hard. The work was tiring, but the students worked toward their ambitious goal of achieving a world first. They have a great sense of achievement, and the number of students who hope to become biologists has increased," said Taruma Akinori, who is in charge of the science course.

They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior. In colonies that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone , chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit. In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs.

In her ten years at Granite Falls,she has revitalized the music programs at both the elementary and high school levels,to the extent that an additional music faculty member was hired by the district to assist with the workload.The growth of the music program in Granite Falls School District has encouraged students to participate in country,state and national music competitions,and won numerous prizes for the district. Teaching music is only a part of Peterson's instruction-it serves as a vehicle to other areas."Music is an amazing tool to unlock students' potential.The most visible benefit from their success in music is their increased confidence and selfesteem," Peterson said."However,I don't believe it is the only benefit,nor the most powerful.It is truly exciting to see how my music teaching can transfer to other classrooms." With this philosophy,Peterson introduced a crosscurriculum program,wherein she takes lessons taught in other classes,such as English and math,and expands upon them in an eightweek unit. One of the most popular projects in Peterson's classes is the creation and performance of a musical,and whereby students create a play from one of the books they have read in another class.Students work together to choose the music that best fits with the overall feel of the play and then perform it for the greater community."Through Andrea's efforts these kids have helped to put Granite Falls,Washington,on the map for musical talents.Parents,staff and community members continue to be in awe of what she is able to bring forth from the children,"said Debra Rose Howell,a colleague of Peterson's at Monte Crisco Elementary School.

In March 2016, AlphaGo, an AI program developed by Google, had the Go match with Lee Sedol, a South Korean Go player. He is the world top player of this old Chinese game. In October 2015, AlphaGo became the first computer program to beat a professional human Go player. And this time, it beat Lee Sedol 4-1. In fact, before the match, most people believed that Lee would certainly be the winner, because they didn't think that AI was good enough to beat the human mind. However, the result was disappointing. As a machine, AlphaGo would never get tired, while Lee Sedol was only a human and humans must have some weaknesses. AlphaGo's wins over a human champion show that computers can do more difficult tasks. Some people may worry whether computers are now smart enough to beat us at everything. But scientists say that is not the case. Real life problems can be more difficult than the Go game. Thomas Johnson, a scientist of AI said, "It's not hard to get a computer program to remember and produce facts. What is hard is getting computers to use knowledge in everyday situation.

mmlu_train_54049 | Treatment for HIV has become more widespread, especially in poorer countries. It's also become cheaper, as medicine companies have lowered their prices for life-saving anti-retroviral drugs . But these drugs are still expensive and many countries are looking to create the biggest impact with limited resources. That's where World Health Organization guidelines come in, says Rochelle Walensky, a disease researcher from Harvard. Walensky and her colleagues used computer programs to model the most cost-effective disease interventions , as well as collected data from clinics in Africa and India about what works best. They found that among the choices of what to do first, earlier anti-retroviral therapy improved five-year survival dramatically and resulted in the longer life expectancy. But cost-effective doesn't always mean affordable, especially for governments in poor countries. Countries still have to make difficult choices about how much treatment they can afford. People in Nairobi, Kenya on Thursday, Dec. 9, 2010, protest a potential free trade area agreement between the EU and India that could see cheap anti-AIDS drugs phased out . However, Walensky notes that first-line anti-retrovirals--those medicine given to newly diagnosed patients that can keep away from symptoms for years - are much cheaper than they were a decade ago. "Second-line therapy have come down quite a bit but not to the level of first-line and countries are having a hard time affording them and increasingly over time, people are going to fail first-line therapy and they're going second-line therapy and then, eventually, they're going to need third-line therapy, some of them." According to Walensky, history has shown that drug prices can come down when international pressure is applied to drug makers.

mmlu_train_6776 | Which are you more likely to have with you at any given moment-your cell phone or your wallet? Soon you may be able to throw your wallet away and pay for things with a quick wave of your smart phone over an electronic scanner. In January, Starbucks announced that customers could start using their phones to buy coffee in 6,800 of its stores. This is the first pay-by-phone practice in the U.S., but we're likely to see more wireless payment alternatives as something called near field communication (NFC) gets into America's consumer electronics. Last December, some new smart phones which contain an NFC chip were introduced to the public. Already in use in parts of Asia and Europe, NFC allows shoppers to wave their phones a few inches above a payment terminal - a contact- free system built for speed and convenience. But before NFC becomes widely adopted in the U.S., a few problems need to be worked out, like who will get to collect the profitable transaction fees. Although some credit card providers have been experimenting with wave-and- pay systems that use NFC-enabled credit cards, cell phone service providers may try to muscle their way into the point-of-sale(POS)market. Three big cell phone service providers have formed a joint venture that will go into operation over the next 15 months. Its goal is "to lead the U.S. payments industry from cards to mobile phone." The other big NFC issue, apart from how payments will be processed, is security. For instance, what's to stop a thief from digitally pick-pocketing you? "We're still not at the point where an attacker can just brush against you in a crowd and steal all the money out of your phone," says Jimmy Shah.

mmlu_train_51075 | Antidepressant drugs such as Prozac were viewed in the early 1900's as wonder pills that would remove depressive blues for good. But in the past five years, growing scientific evidence has shown these drugs work for only a minority of people. And now a research journal says that these antidepressants can make many patients' depression worse. This alarming suggestion centres on the very chemical that is targeted by antidepressants-serotonin . Drugs such as Prozac are known as selective serotonin re-uptake inhibitors(or SSRIs). Their aim is to increase the level of this "feel-good" chemical in the brain. But the new research, published in the journal Frontiers In Evolutionary Psychology, points out that serotonin is like a chemical Swiss Army knife, performing a very wide range of jobs in the brain and body. And when we start changing serotonin levels purposely, it may cause a wide range of unwanted effects. These can include digestive problems and even early deaths in older people, according to the study's lead researcher Paul Andrews. " We need to be much more cautious about use of these drugs," says Andrews, an assistant professor of evolutionary psychology at McMaster University in Ontario, Canada. Previous research has suggested that the drugs provide little benefit for most people with mild depression, and actively help only a few of the most severely depressed. Famous psychologist Irving Kirsch has found that for many patients, SSRIs are no more effective than a placebo pill. A research in 2010 on Danish children found a small, but significant, increase in the risk of heart problems among babies whose mothers had used SSRIs in early pregnancy. The key to understanding these side-effects is serotonin, says Andrews. Serotonin is also the reason why patients can often end up feeling still more depressed after they have finished a course of SSRI drugs. He argues that SSRI antidepressants disturb the brain, leaving the patient an even greater depression than before. "After long use, when a patient stops taking SSRIs, the brain will lower its levels of serotonin production," he says, adding that it also changes the way receptors in the brain respond to serotonin, making the brain less sensitive to the chemical. These changes are believed to be temporary, but studies indicate that the effects may continue for up to two years. Most disturbingly of all, Andrews' review features three recent studies which, he says , show that elderly antidepressant users are more likely to die earlier than non-users, even after taking other important variables into account. One study, published in the British Medical Journal last year, found patients given SSRIs were more than 4 per cent more likely to die in the next year than those not on the drugs. "Serotonin is an ancient chemical," says Andrews. "It is regulating many different processes, and when you disturb these things, you can expect that it is going to cause some harm." Stafford Lightman, professor of medicine at the University of Bristol, and a leading UK expert in brain chemicals and hormones, says Andrews' review highlights some important problems, yet it should also be taken with a pinch of salt. "This report is doing the opposite of what drug companies do," he says. "Drug companies selectively present all the positives in their research, while this search selectively presents all the negatives that can be found. Nevertheless, Andrews' study is useful in that it is always worth pointing out that there is a downside to any medicine. " Professor Lightman adds that there is still a great deal we don't know about SSRIs-not least what they actually do in our brains. When it comes to understanding why the drugs work only for a limited part of patients, U.S. scientists think they might now have the answer. They think that in many depressed patients, it's not only the lack of feel-good serotonin causing their depression, but also a failure in the area of the brain that produces new cells throughout our lives. This area, the hippocampus, is also responsible for regulating mood and memory. Research suggests that in patients whose hippocampus has lost the ability to produce new cells, SSRIs do not bring any benefit. What is the text mainly about? | [

mmlu_train_45918 | A study of a million UK women, published today in The Lancet, has shown that happiness itself has no direct effect on mortality, and that the widespread but mistaken belief that unhappiness and stress directly cause ill health came from studies that had simply confused cause and effect. Life-threatening poor health can cause unhappiness, and for this reason unhappiness is associated with increased mortality. In addition, smokers tend to be unhappier than non-smokers. However, after taking account of previous ill health, smoking, and other lifestyle and socio-economic factors, the investigators found that unhappiness itself was no longer associated with increased mortality. The lead author, Dr Bette Liu, now at the University of New South Wales, Australia said: "Illness makes you unhappy, but unhappiness itself doesn't make you ill. We found no direct effect of unhappiness or stress on mortality, even in a ten-year study of a million women." As in other studies, unhappiness was associated with deprivation, smoking, lack of exercise, and not living with a partner. The strongest associations, however, were that the women who were already in poor health tended to say that they were unhappy, stressed, not in control, and not relaxed. The main analyses included 700 000 women, average age 59 years, and over the next 10 years these women were followed by electronic record linkage for mortality, during which time 30 000 of the women died. After allowing for any differences already present in health and lifestyle, the overall death rate among those who were unhappy was the same as the death rate among those who were generally happy. The study is so large that it rules out unhappiness being a direct cause of any material increase in overall mortality in women. This was true for overall mortality, for cancer mortality, and for heart disease mortality, and it was true for stress as well as for unhappiness. It's wrongly believed that _ . | [

mmlu_train_9118 | In 1977, Irene Pepperberg of Harvard University began studying what was on another creature's mind by talking to it. Her first experiments began with Alex. Alex was a one-year-old African grey parrot and Irene taught him to produce the sounds of the English language. "I thought if he learned to communicate, I could ask him questions about how he sees the world." At the time, most scientists didn't believe animals had any thoughts. They thought animals were more like robots but didn't have the ability to think or feel. Of course, if you own a pet you probably disagree. But it is the job of a scientist to prove this and nowadays more scientists accept that animals can think for themselves. "That's why I started my studies with Alex," Irene said, "Some people actually called me crazy for trying this." Nowadays, we have more and more evidence that animals have all sorts of mental abilities. Sheep can recognize faces. Chimpanzees use a variety of tools and even use weapons to hunt. And Alex the parrot became a very good talker. Thirty years after the Alex studies began. Irene was still giving him English lessons up until his recent death. For example, if Alex was hungry he could say "want grape". Alex could count to six and was learning the sounds for seven and eight. "He has to hear the words over and over before he can correctly say them." Irene said, after pronouncing "seven" for Alex a few times in a row. Alex could also tell the difference between colors, shapes, sizes, and materials (e.g. wood and metal). Before he finally died, Alex managed to say "seven". Another famous pet that proved some animals have greater mental skills was a dog called Rico. He appeared on a German TV game show in 2011. Rico knew the names of 200 different toys and easily learned the names of new ones. When Rico became famous, many other dog owners wanted to show how clever their pets were. Another dog called Betsy could understand 300 words. One theory for dogs' ability to learn a language is that they have ben close companions to humans for many centuries and so their ability to understand us is constantly evolving . While animals can't do what humans do yet, some scientists believe that examples like Alex and Rico prove that evolution develops intelligence, as well as physical appearance.

mmlu_train_35918 | A growing number of health, hunger, and sustainable agriculture groups today announced plans for Food Day-a nationwide campaign to change the way Americans eat and think about food.Food Day will encourage people around the country to sponsor or participate in activities that encourage Americans to "eat real" and support healthy, affordable food grown in a sustainable, humane way. Organizers hope Food Day will inspire Americans to hold thousands of events in schools, college campuses, houses of worship and even in private homes aimed at fixing America's food system.A Food Day event could be as small as a parent organizing a vegetable identification contest at a kindergarten class-or as massive as a rally in a city park, with entertainment and healthy food.Health departments, city councils and other policy makers could use Food Day to launch campaigns, hold hearings, or otherwise address communities food problems. The campaign will advocate progress toward five central goals: *Reducing diet-related disease by promoting healthy foods.The American diet is too low in fruits, vegetables, and whole grains and too high in fatty meat, soft drinks and salty packaged and restaurant foods-contributing to hundreds of thousands of premature deaths each year. *Supporting sustainable farms and stopping subsidies to agribusiness.Billions of federal dollars a year would be better spent helping environmentally conscious family farmers than hugeagribusiness operations. *Expanding access to food and alleviating hunger.Far too many Americans don't know where their next meal is coming from, or have access to fresh produce in their neighborhood. *Reforming factory farms to protect animals and the environment.Farming of animals can and should be done without cruelty, and without degrading the quality of life. *Curbing junk-food marketing to kids.Food companies should not be targeting children with foods that promote tooth decay, obesity and other health problems.

At age 15,Winter Vinecki has already had more successes than most people have in their lifetime."I recently completed a marathon on all seven continents and became the youngest person in the world to do so.And I was really doing this for my dad." Doctors discovered that Winter's father had a rare and deadly form of prostate cancer when she was nine years old.Then he died 10 months later."When he was first diagnosed with prostate cancer I immediately knew I had to do something to help him.That's when I formed Team Winter for prostate cancer research and awareness." Through Team Winter and social media,Winter Vinecki has raised almost 500,000 dollars.She has taken prostate cancer education worldwide through foot races called marathons,on seven continents.In the United States she travels continually to talk about prostate cancer and urge others to act. Winter Vinecki attended a conference recently in Los Angeles,California and spoke at the conference as one of several teenagers who spoke about young people who were living extraordinary lives. "So prostate cancer is much more common but men don't want to talk about it.So that is why a ten-year-old girl had to go out there and start talking about it for them." Another speaker was Jack Andraka who invented a sensor which is not as expensive as traditional equipment that can't be afforded by most common people.It can identify cancers of the pancreas and lungs.He was 15 at the time. Jack is now 17 and seeking patents for his latest inventions.He has developed low-cost water quality equipment which can help identify and remove heavy metals and poisonous chemicals from water.

mmlu_train_13046 | ATLANTA, Georgia--- Alternative medicine --- including yoga, meditation, herbs and the Atkins diet ---appears to be growing in popularity in the United States, perhaps because of dissatisfaction with conventional care, the government said Thursday. More than a third of American adults used such practices in 2002, according to the government survey of 31,000 people, the largest study on non-conventional medical approaches in the United States.If prayer is included, about 62 percent of U.S.adults used some form of alternative medicine. The results seem to indicate more people are turning to alternative medicine, though the 2002 survey could not be directly compared to previous studies because of differences in size and survey methods, health officials said. The top alternative therapies included prayer (43 percent of adults) , natural products(19 percent), meditation(8 percent)and diets such as Atkins, Ornish, or the Zone (4 percent).More people also are using natural products such as herbs or enzymes to treat chronic or recurring pain , said Richard Nahin of the National Center for Complementary and Alternative Medicine, part of the National Institutes of Health. "Many conditions are not easily treated with conventional medicine," Nahin sad. "It may be the public that is turning to complementary and alternative medicine because it's not getting relief from conventional medicine." But people should not be turning away from conventional treatments that are proven safe, said Dr.Stephen Straus, director of the alternative medicine center. "People are making individual decisions to neglect those therapies and we have concerns about those choices," he said. Health officials said they were concerned that 13 percent of those surveyed said they turned to alternative medicine because regular medicine is too expensive. "It needs to be explored ---we need to find out whether they were insured or not" Nahin said. Health officials also were surprised that 6.6 percent of those surveyed used the supplement kava , which has been associated with liver disease. "People make the assumption that because something is natural that it's safe" Nahin said. "But a number of studies have shown that natural products can be unsafe when used inappropriately or with other drugs." He said people considering using alternative medicine should consult their doctor first. From the passage we know that most people choose alternative medicine _ . | [

mmlu_train_26721 | Last week,Bill Gates retired from full-time work at the world's biggest computer software company, Microsoft.He will remain chairman of the company he established with Paul Allen in nineteen seventy-five. Mister Gates leaves Microsoft at a time of change in the computing industry.Microsoft grew at a time when personal computers,or PCs,were replacing big mainframe computers as the main computing tools.He showed that huge profits could be made in software as PCs increasingly were found "on every desk and in every home." Early on,Microsoft understood the importance of the "network effect." That is, software is the kind of product that increases in value as more people buy and use it. Now,free Internet software threatens to replace PC-based software.Devices like "smart phones" connect people to the Internet.Google has become a 1eader in Internet Web searching and advertising.Microsoft has struggled to change with the new computer environment.Its efforts to sell music and its latest operating system,Vista,have not been big successes.And an attempt this year to buy Yahoo for over forty-seven billion dollars failed. In the last several years,Bill Gates has slowly given control of Microsoft to others.In two thousand,he gave the job of chief executive officer to Steve Ballmer, a friend of his since their years at Harvard University.Mister Ballmer has been with Microsoft since nineteen eighty.Still,it is hard to overestimate the influence of Bill Gates on computing.He developed the business model that put the Windows operating system on about ninety percent of the world's one billion PCs.Microsoft now has almost ninety thousand employees. At fifty--two years old,Bill Gates is currently the third richest man in the world.He is worth about fifty-eight billion dollars.He remains Microsoft's biggest shareholder.

mmlu_train_47706 | New research shows that overweight or even mildly obese people have a lower risk of early death than people considered to be normal weight. Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico. The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals. Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death. "Because we'd actually already read a lot of this literature and realized it was likely that mortality rates for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn't seem to differ from normal weight." But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese. The study has raised new questions about "body mass index," or BMI. This is a measurement of body fat as a ratio of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person's BMI can be misleading in some cases. Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular. Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes .

mmlu_train_62472 | The head of the World Health Organization (WTO) yesterday warned of worsening health in the country's vast rural areas while praising the government for its commitment on improving healthcare in the countryside. "The health indicators have failed to improve in pace with economic indicators." said Margared Chan when addressing a conference on rural primary healthcare in prefix = st1 /China. "The health gap between rural and urban areas has grown even wider and health in parts of rural China is deteriorating ,"she said, adding medical costs are rising faster than the growth of per capital income in rural areas. She said she appreciated the government's efforts and plans to build a medical system for all people. Saying "when fair and accessible public health services become the clear targets of a country's public health policy, people's health will improve." The WTO chief said she noticed that the tasks on improving people's well-being in the report by Party chief Hu Jintao at the 17thNational Congress of the Communist Party of China included a basic medical insurance system for urban dwellers and a cooperative medical care system in rural areas. She said recent WTO research has found that diseases are the source of poverty for 30 to 50 percent of the rural population of 737 million. A growing number of rural people, especially the aged, are suffering from various diseases; however, few have access to decent healthcare, she told the conference. Chan criticized the practice of allowing healthcare services to be commercialized in rural areas, warning it will cause the patients more suffering. The government has pledged to provide its population with basic medical care by 2020. It's expanding medical care through the Rural Cooperative Medical Scheme, a plan under which subscribers are provided with 50 yuan($6.4) per person--20 yuan ($2.6) each from the central and local governments and 10 yuan ($1.3) from the individual. Vice-Minister of Health Chen Xiaohong said nearly 85 percent of the country's rural area, or 2,429 counties, are participating in the plan.
