In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.

Example Input: Article: The percentage of districts that require elementary schools to teach physical education increased, to 93% last year from 83% in 2000. But just 4% of elementary schools, 8% of middle schools and 2% of high schools provided physical education each school day, as is recommended by the disease control agency. One-fifth of schools did not require physical education at all. In 2004, Congress passed a law requiring each school district to develop a "wellness policy" to promote the students' health by setting goals for nutrition education and physical activity. Those policies are just now taking effect, and some school administrators predict that the next survey will show more marked improvements. Some schools have set out to place health education on the same requirement with academics. In Los Angeles County, Sepulveda Middle School has banned soft drinks and eliminated unhealthy snacks from the school store. Salad, fruit and yogurt are always available in the cafeteria, said Patricia J. Pelletier, the principal. Nearly an hour of physical education is required daily, the school offers after-hours training in distance running, and it has started a class on healthy cooking for parents. "If kids are healthy and have healthy lifestyles, they're going to be better students," Ms Pelletier said. "They're going to be in school, and they're going to be connected with the teachers in a better way." The survey found that nearly two-thirds of schools prohibited tobacco use at all places, including at off-campus functions, up from 46% in 2000. Another finding was that the proportion of states that require middle schools to teach human sexuality grew, to 59% from 46%. The report found a variety of indications of healthier cooking in school cafeterias. 55% reported that they had removed the skin from poultry before cooking, up from 40%, and 46% now use low-fat cheeses, up from 31%. But 12% of elementary schools, 19% of middle schools and 24% of high schools offer students brand-name fast food from businesses like Pizza Hut and Taco Bell.

Example Input: Article: International teams have spent nearly half a year looking for evidence of the missing Malaysian Airlines plane, a search that includes the hunt for the aircraft's so-called black box, which holds flight data that would likely explain what caused MH370 to move away from its course. But many aviation experts wonder why, in our increasingly networked world, divers are searching the Indian Ocean for a metal box when technology already exists that would enable planes to stream black box data to the ground in the event of an emergency. Black boxes have been on planes since the late 1950s, and now every commercial aircraft has two: a flight data recorder and a voice recorder. (Although they are referred to as black boxes, they are typically orange in color, making them easier to spot in waters.) Black box recorders are mainly used to investigate the cause of in-flight accidents. While black boxes are built to survive a crash and long-term submersion in water, it can be a real challenge to find the device if a plane has gone down in the ocean. While each box contains a beacon , the unit only has enough battery power to transmit a signal for 30 days. After the crash of Air France Flight 447 in the Atlantic Ocean in June 2009, it took divers two years to find the black box. Pierre Jeanniot, a Canadian engineer who helped perfect black box technology about 40 years ago, feels that the device, in its current form, is " _ ". He started to question its effectiveness more than a decade ago, after seeing the broken pieces of the black boxes in the 2001 attacks on the World Trade towers in New York. Jeanniot is now on the advisory board of a Toronto-based firm that has built a live-streamed black box system. When a plane experiences an irregular event, the system can send streaming data off the aircraft to one of the satellites and then down to ground-based servers, where the message is interpreted and sent to the airline. It seems necessary that the loss of MH370 and other similar cases wake more people up to the fact that the tools being used at this stage are inadequate for dealing with emergency situations, Jeanniot says. He also estimates that if this technology had been on board the missing Malaysian Airlines flight and live-streaming for the estimated seven hours after the flight first experienced a problem, it would have cost about $3,000. While there is widespread approval of a live-streamed black box system, most airlines see its cost prohibitive. The airline industry is an industry with small profits, and is reluctant to add costs that will further cut the bottom line. However, given how much time, money and effort has been spent on the luckless search for MH370, s black box, the cost of operating a live-streaming version seems like a trifle
Question: Which fact is mentioned to support aviation experts' doubt about the effectiveness of the black box?
Options: (A) MH370's black box holds flight data that might explain what happened to the aircraft. (B) The recorders are actually orange in color though referred to as black boxes. (C) The beacon in the black box has limited battery power to send out a signal for 30 days. (D) It's necessary for people to wake up to the weaknesses of the black box
Asnwer: A
Example Output: No

Example Input: Article: With only two weeks to go before Christmas, buying presents is a lug priority for a lot of people. However, this year not so many people are leaving their homes to browse around the shops. These days lots of people do their shopping in the comfort of their own home with the help of the Internet.
