Question: Article: Nowadays with the development of agriculture, farmers use more technology. However, they are being told more needs to be done to stop them injuring at work. One in five British workplace deaths happens in agriculture even though farmers are only a small part of the working population. During the year 2012/13 there were 1,061 injuries in total and it is thought many more go unreported. Jim Chapman from Warwickshire had his arm torn off by farm machinery seven years ago when he was 23. "You don't realize how much you rely on your second arm until it's gone," he said. He fell against a PTO shaft , a spinning metal bar at the back of a tractor. "It catapulted me from one side of the machine to the other," he said. "I landed on the floor, minus all my clothing. My left arm had been torn off." He admits that the machinery was missing part of its proper safety guard. "But again," he added, "it was a rushed day. There were a few machines that didn't work. Also, I was getting behind with the jobs." Over the last 10 years, other industries that you'd think of as dangerous, like building or quarrying , have lowered the number of workplace deaths and injures. In the farming industry though, deaths remain high with 34 deaths in 2012/13. Judith Hackett, the chair of the Health and Safety Executive (HSE) says it is "not acceptable" that the accident statistics for farming are still high. "People in farming don't have minor injuries. When they get injured, it's bad." She said. "When I said to the National Farmers' Union (NFU) that if I had sons I would not want them to work in agriculture, it really made them sit up and take notice." There's a whole host of reasons why farming is as dangerous as it is. It is a very rough industry. Also, it's often because people are left alone. They could be young and inexperienced, or older people, who would have retired maybe 5 or 10 years ago in other industries. Jim wants others to learn from his experience. "Look at what you're doing before you go running in," he said. "You could make a mistake that you'll live with for the rest of your life."
Answer: he was standing at the back of the tractor

Answer: Jim Chapman was injured in the workplace mainly because _ .

Question: Article: Long after the 1998 World Cup was won, disappointed fans were still cursing the disputed refereeing decisions that denied victory to their team. A researcher was appointed to study the performance of some top referees. The researcher organized an experimental tournament involving four youth teams. Each match lasted an hour, divided into three periods of 20 minutes during which different referees were in charge. Observers noted down the referees' errors, of which there were 61 over the tournament. Converted to a standard match of 90 minutes, each referee made almost 23 mistakes, a remarkably high number. The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were more likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum distance is about 20 meters. There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second. If FIFA, football's international ruling body, wants to improve the standard of refereeing at the next World Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues. He also says that FIFA's insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.
Answer: analyse the causes of errors made by football referees

Answer: The experiment conducted by the researcher was meant to _ .

Question: Article: Many women write to me perplexed about why they can't form close friendships. They try new approaches, put themselves in all the right places, see therapists, and read relevant self-help books. They consider themselves interesting, loyal, kind and friend-worthy people. But for reasons unknown to them, they have a tough time forming intimate relationships. Many admit to not having even one close friend. A recent study published in the offers some clues as to how both nature (personality) and nurture (experience) impact our friendships. Researchers at the University of Virginia and University of Toronto, Mississauga studied more than 7,000 American adults between the ages of 20 and 75 over a period of ten years, looking at the number of times these adults moved during childhood. Their study, like prior ones, showed a link between residential mobility and adult well-being: The more times participants moved as children , the poorer the quality of their adult social relationships. But digging deeper, the researchers found that personality--specifically being introverted or extroverted -- could either intensify of buffer the effect of moving to a new town or neighborhood during childhood. The negative impact of more moves during childhood was far greater for introverts compared to extroverts. "Moving a lot makes it difficult for people to maintain long-term close relationships," stated Dr. Shigehiro Oishi, the first author of the study, in a press release from the American Psychological Association, "This might not be a serious problem for outgoing people who can make friends quickly and easily. Less outgoing people have a harder time making new friends." Families often have to relocate -- across town, across the country, or across the globe. Yet, in many cases, their kids and young adolescents haven't yet built up a bank of friendships. So the conventional wisdom is to try to minimize moves for the sake of your child, whenever possible , and to move at the end of the academic year.
