I'm taking a test and have to guess the right answer to the question after the article. Article: Air traffic controllers in the US have been advised to take 26-minute naps , after a series of accidents involving workers falling asleep. Now the National Transportation Safety Board (NTSB) is calling for "controlled naps" during nightshifts . NTSB member Mark Rosekind said that a 26-minute nap would improve performance by 34%. He believes that beyond the aviation industry, other professions, such as motoring and machinery, also carry obvious risks. But other experts doubt whether 26 minutes is the appropriate napping time. It's a bit too long and risks you falling into a deep sleep, says Jim Horne, director of the Sleep Research Council. He said, "A nap of about 15 minutes is best; once you get beyond 20 minutes, you risk a deep sleep and you can be much more tired when you wake up. Therefore, we suggest that a nap be combined with a cup of coffee so that you can enjoy an effective sleep before the caffeine takes effect in 20 minutes. However, this method only works on those who have had a poor night's sleep. If you haven't had a sleep the night before, this method won't be enough to make you fresh." Health writer, Linda Wasmer Andrews, also believes that 26 minutes is too long. She says a nap between 10 and 20 minutes is enough, and the timing of the nap is also important. Putting your head down too early means your body may not be ready to sleep yet, but a nap that is too late in a day might make it harder to fall asleep. Early afternoon is often the best time, between l pm to 3pm, when people experience a post-lunch decrease in energy. Question: According to Linda Wasmer Andrews, _ . Options: A: 2 pm is an appropriate napping time B: people's energy will increase after lunch C: your body is ready to sleep at late time in the day D: a late nap may lead to sleep problems during the night

I'm taking a test and have to guess the right answer to the question after the article. Article: Everyone knows that regular bedtimes are important, especially for children. But a research by Yvonne Kelly of University College, London, shows that daughters, it seems, do benefit from regular bedtimes. Sons do not. Dr Kelly and a team of colleagues examined the bedtimes and cognitive abilities of 11,178 children born in Britain between September 2000 and January 2002, who took part in a research project called the Millennium Cohort Study. The bedtime information they used was collected during four visits interviewers made to the homes of those participating in the study. These happened when the children were nine months, three years, five years and seven years of age. Besides asking whether the children had set bedtimes on weekdays and if they always, usually, sometimes or never made them, interviewers collected information about family routines, economic circumstances and other matters--including whether children were read to before they went to sleep and whether they had a television in their bedroom. The children in question were also asked, at the ages of three, five and seven, to take standardised reading, mathematical tests, from which their IQs could be tested. Dr Kelly's report shows that by the time children had reached the age of seven, not having had a regular bedtime did seem to affect their cognition. But that was true only if they were female. On the IQ scale, whose average value is 100 points, girls who had had regular bedtimes scored between eight and nine points more than those who did not. Boys were not completely unaffected. Irregular bedtimes left their IQs about six points below those of their contemporaries at the age of three. But the distinction disappeared by the time they were seven. This difference between the sexes is puzzling. "I did not expect it, and more research is necessary." said Dr Kelly. Question: How long did the research last? Options: A: At least nine months B: Nearly three years C: Less than five years D: About seven years
