Input: Consider Input: 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

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

Input: Consider Input: Article: Using the Internet , doctors "can answer more questions from more patients in a shorter time, " writes Dr Badal Pal, a famous doctor in Manchester, IJK. According to Pal, nearly 40% of American patients say they have used e-mail to communicate with a doctor in the past. He notes however, that although patients have such interest, only up to 2% of doctors in the United States offer e-mail services. Using e-mail, doctors can make sure of their advice and point patients to patients information materials and sources on the Internet. It's said that more than 10.000 health-oriented websites already exist now. However some people worry that widespread use of medical e-mail might set up two kinds of care--one "haves" and another for the "have-nots". But Pal points out that "In the near future nearly every library will offer (Internet and e-mail)services in the United States, " allowing even low-income patients to use such means. Pal also talks about other possible barriers to acceptance of medical e-mail. "Doctors may be unwilling to offer e-mail services for fear of increasing workload and uncertainty about the time they spent," he explained, and patients may worry that their medical information might be read by others. "But these problems can all be solved," he adds. E-mail may well help us a lot in health care, Pal concludes. "Patients want to know more than they can get in normal clinics," he points out, "and they might find communication on the information superhighway less fearful than face-to-face dialogue with their doctors."
Answer: by e-mail

Output: The article introduces a new way of patient-doctor communication _ .

Input: Consider Input: Article: I got your letter and was glad to find that you had not forgotten Jourdon, and that you wanted me to come back and live with you again in Tennessee, promising to do better for me than anybody else can. Although you shot at me twice before I left you, I did not want to hear of your being hurt. It would do me good to go back to the dear old home again and see Allen, Esther, Green, and Lee. Give my love to them all, and tell them I hope we will meet in the better world, if not in this. I want to know particularly what the good chance is you propose to give me. I am doing tolerably well here in Ohio. I get twenty-five dollars a month, with food and clothing; have a comfortable home for Mandy, the folks call her Mrs. Anderson; and the children--Milly, Jane, and Grundy--go to school and are learning well. The teacher says Grundy has a head for a preacher. We are kindly treated. Now, if you will write and say what wages you will give me, I will be better able to decide whether it would be to my advantage to move back again. We have concluded to test your sincerity by asking you to send us our wages for the time we served you. This will make us forget and forgive old scores and rely on your justice and friendship in the future. I served you faithfully for thirty-two years, and Mandy twenty years. At twenty-five dollars a month for me, and two dollars a week for Mandy, our earnings would amount to eleven thousand six hundred and eighty dollars. Add to this the interest for the time our wages have been kept back, and deduct what you paid for our clothing, and three doctor's visits to me, and pulling a tooth for Mandy. If you fail to pay us for faithful labors in the past, we can have little faith in your promises in the future. In answering this letter, please state if there would be any safety for my Milly and Jane, who are now grown up, and both good-looking girls. I would rather stay here and starve--and die, if it should come to that--than have my girls brought to shame by the violence and wickedness of their young Masters. You will also please state if there has been any schools opened for the colored children in your neighborhood. The great desire of my life now is to give my children an education and have them form virtuous habits. Say howdy to George Carter, and thank him for taking the pistol from you when you were shooting at me.
