input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Dr. Jack M. Gwaltney, Jr. a professor at the University Of Virginia School Of Medicine infected six student volunteers with virus, the most common cause of colds. A few days later, when they were coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1 members spent three days and nights in the same room with one of the infected students, separated by a screen so they couldn't touch one another. Group 2 sat around a table while an infected volunteer talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and then touched their own noses or eyes. Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected physical contact might play an important role. Sure enough, of the 15 people who had touched a student volunteer, 11 became infected--compared with only one of those who had been sitting at the table, and none who had spent three days and nights together. "The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting virus," says Gwaltney. The study was one of a series that helped establish Gwaltney's reputation as a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common Cold." When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean 'get rid of', I don't think we're going to be able to do that with cold viruses any time soon. But if you look in the dictionary, you'll see that 'cure' is explained as a successful treatment. And we're not just getting more effective at treating the symptoms --we're getting at the root cause too. " Options: A a newly-found virus B a nickname of respect to Dr. Gwaltney C a method to cure colds D a way by which the other scientists laughed at Dr. Gwaltney Answer: B a nickname of respect to Dr. Gwaltney Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Nowadays, there's a lot of debate about single sex education since it has begun to regain its popularity recently. According to long term studies of children from around the world, students achieve more and learn better in single sex schools. An Australian study of 270,000 students found that both boys and girls performed much higher on standardized tests when they attended separate schools. During an experiment in Virginia in 1995, 100 eighth graders were separated just for math and science courses. Almost immediately, the girls began to achieve more, become more confident and take part more often in class activities. In 2001, a British study concluded that nearly every girl regardless of her ability or socio-economic status performed better in single sex classrooms than co-ed ones. The study of 2,954 high schools and 979 primary schools showed that while boys at the lowest levels in study improved the most in single sex schools, single sex education was particularly beneficial to girls. Every one of the top 50 private elementary schools and top 20 private high schools in Britain are single sex schools. Girls became more confident in themselves as students and earned higher scores on their College Board and Advanced Placement examinations. A quarter of the female members of the US Congress and one-third of all female members of Fortune 100 boards graduated from all-women's colleges. While the statistics are not as dramatic for boys, however, boys tend to soften their competitive edge and become more cooperative in a single sex setting. They can just be boys and not worry about what the girls might think. Single sex education has a pleasant way of encouraging children to be fearless, to be curious, to be enthusiastic --- in short, to just be themselves. Children are subjected to pressures from every quarter to become adults before they are ready to do so. They grow up too quickly. Why not let them be children for a few more years? Single sex education with its gentler, more controlled social atmosphere... Options: A single sex education has become popular in recent years B the effect of single sex education on girls is immediate C students at separate schools are better prepared for standardized tests D both boy and girl students achieve more and learn better in single sex schools Answer: B the effect of single sex education on girls is immediate Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: WASHINGTON---At least four more U.S. air-traffic controllers are caught nodding off on the job at three separate airports across the nation, the government said Wednesday. The controller working alone in the tower fell asleep and was out of communication for 16 minutes while a medical flight carrying a patient was trying to land at about 2 A.M. Wednesday at Reno-Tahoe International Airport in Nevada, the Federal Aviation Administration (FAA) said in a statement. The FAA announced that it is also investigating a controller who fell asleep Monday at Boeing King County International Airport in Seattle and two controllers who were unresponsive at Preston Smith International Airport in Lubbock, Texas, on March 29.The agency had earlier revealed that an air-traffic supervisor fell asleep March 23 at Ronald Reagan Washington National Airport and a controller slept for five hours at McGhee Tyson Airport in Knoxville, Tennessee on Feb.19. "I am sick of this," Senate Commerce, Science and Transportation Chairman Jay Rockefeller, a West Virginia Democrat, said in a statement. "We can't have an aviation system where some of the people responsible for safety are asleep at the switch." As the incidents pile up, sleep experts say it demonstrates that the agency faces a systemic issue with the thousands of people expected to work through the night in safety-critical jobs. Scientific research shows that workers on midnight shifts make more errors because it is so difficult for the body to adapt to sleeping during the day, they say. ks5u The agency will add an extra controller at the 27 towers staffed with one worker on the midnight shift, the FAA statement said. Agency chief Randy Babbitt and the controllers' union president, Paul Rinaldi, will visit facilities around the country next week to reinforce the need for "the highest professional standards," according to the FAA. Doug Church, a spokesman for Rinaldi of the National Air Traffic Controllers Association, didn't immediately return a telephone call for comment.... Options: A The controllers were working alone while they were on duty B The incidents are rooted in fatigue problems and those on midnight shifts need an extra nap C In the U.S. , thousands of people expect to work through the night in safety-critical jobs D The agency has added an extra controller at the 27 towers Answer: B The incidents are rooted in fatigue problems and those on midnight shifts need an extra nap Question:???
