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: An astronomer is making a case for launching pop singer Justin Bieber into suborbital space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager -- he would come back down to Earth eventually, after all -- but rather to help jump-start the emerging suborbital spaceflight industry. It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "If there's more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good." Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport. None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z. Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists -- but Shostak is thinking about ways to make it grow. A celebrity launch isn't Shostak's only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling with cameras both inside and out, to give the public dramatic views of every mission. Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry's success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space. 
 Question: Why may Justin Bieber be sent into suborbital space?

 Asnwer: B
Example Output: Yes

Example Input: Article: To the untrained eye it might seem like just a bit of a monkey trick. But when Milly the mandrill (, ) covers her face with her hand she is actually sending a serious message to her fellows: "Leave me alone!" Experts believe the 15-year-old mandrill invented the gesture to warn other monkeys at Colchester Zoo to give her some space. And, surprisingly, the signal has been picked by other members of the group, who use it when they too require _ . Biologist Mark Laidre believes the behavior is evidence of social culture among the mandrills. Importantly, the sign language is unlikely to have been influenced by human activities because mandrills do not copy humans. Mr. Laidre expects further research will uncover other monkeys using cultural gestures -- the ability to communicate with the hands in a meaningful way. "By covering their eyes with their hands, possibly conveyed to others that they wanted to be left alone and this message may have been respected as a 'do not disturb' sign," said Mr. Laidre. While the hand is in place, other monkeys are not likely to approach or touch the monkey. Those who rank lower in the social order also use the technique to avoid attacks from more powerful group members. As the discovery appears to be unique to Colchester Zoo, it suggests it is a local phenomenon that arose naturally in the community of 25 mandrills. Curator   Sarah Forsyth said: "We believe Milly made up the signal and over the past five years some of the younger mandrills have picked it up. We're not sure why she started doing it but it could be as simple as 'I can't see them, so they can't see me'. It really does show you how intelligent mandrills are."

Example Input: Article: Once a father was seated at the dinner table with his wife and children. A good friend who had come to visit was eating with them. While they were sitting there the clock struck twelve,and the stranger saw the door open and a very pale little child dressed in snow-white clothes come in. It neither looked around,nor did it speak,but went straight into the next room. Soon afterwards it came back,and just as silently went out of the door again. On the second and an the third day it came back in exactly the same manner. Then the stranger finally asked the father, whose beautiful child it was that went into the next room every day at noon. "I did not see it,"he said,adding that he did not know whose child it might be. The next day when it again came,the stranger pointed it out to the father, but the latter did not see it,nor did the mother and the children see anything. Then the stranger got up,went to the door of the room,opened it a little,and looked in. There he saw the child sitting on the floor, and busily digging and rooting about in the cracks in the floor. When it saw the stranger, it disappeared. He now told what he had seen and described the child exactly.Then the mother recog- nized it, and said,"Oh,it is my dear child who died four weeks ago." They ripped up the floor and found two farthings which the child had once received from its mother to give to a poor man. It,however, had thought,"with that money you can buy yourself a piece of zwieback,"and had kept the farthings,hiding them in the cracks in the floor.www.ks5u.com Therefore it had had no rest in its grave,and had come every day at noon to look for these farthings. Then the parents gave the money to a poor man,and after that the child was never seen again.
