Question: I'm taking a test and have to guess the right answer to the question after the article. 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.... Question: We can infer from the passage that _ . 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

Question: I'm taking a test and have to guess the right answer to the question after the article. Article: Is It Worth Buying Organic Food? Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels . However, if you think paying a little more for organic food gets you a more nutritious and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren't necessarily more nutritious, and they're no less likely to suffer from disease-causing bacteria, either. The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. "We did not find strong evidence that organic food is more nutritious or healthier," says Dr. Crystal Smith-Spangler from Stanford. "So consumers shouldn't assume that one type of food has a lower risk or is safer." For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats. While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends. Organic food is produced with fewer chemicals and more natural-growing practices, but... Question: Smith-Spangler and her colleagues found that _ . Options: A: organic food could reduce the risk of heart disease B: traditional food was grown with more natural methods C: both organic and traditional food they examined were safe D: there was not a presence of any forms of bacteria in organic food
Answer: C
