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: Article: Homework can put you in a badmood , and that might actually be a good thing. Researchers from the University of Plymouth in England doubted whether mood might affect the way kids learn. To find out the answer, they did two experiments with children. The first experiment tested 30 kids. Someshapes were hidden inside a different, larger picture. The kids had to find the small shapes while sitting in a room with either cheerful or sad music playing in the background. To test their mood, the scientists asked the kids to point to one of five faces, from happy to sad. Children who listened to cheerful music tended to point to the smiley faces while the others pointed to the unhappy ones. The researchers found that sad kids took at least a second less to find the small shapes. They also found an average of three or four more shapes. In the second experiment, 61 children watched one of two scenes from a film. One scene was happy, and the other was sad. Just like in the first experiment, kids who saw the sad scene acted better compared to the others. The researchers guessed that feeling down makes people more likely to focus on a problem or difficult situation. Not all scientists agree with them, however. Other studies argued that maybe, that cheerful music in the first experiment distracted kids from finding shapes. While scientists work on finding out the answers, it still might be wise to choose when to do your tasks according to your mood. After eating a delicious ice cream, for example, write an essay.

Problem: Article: On the site of the 9/11 tragedy, Irish university professor Elizabeth Stinger Keefe found an image of hope-- a wedding photo of a happy couple and their friends lay among the rubble  of the Twin Towers. As a gesture of goodwill, she decided to try and reunite the picture with either its owner or a  . Every year, on the anniversary of the terrorist attacks, she would make an attempt, posting the picture on social media and asking others to share it. Finally, after a remarkable 13 years, her work paid off. Thanks to the power of social media, her appeal was more widely shared than ever before. A man named Fred Mahe called Ms Keefe after the image went viral -- to tell her that he was in fact in the picture and that all six people photographed were alive and well. He said that the image belonged to him and had been lost in the rubble after 9/11.The photo was originally taken at a friend's wedding in Colorado, earlier in 2001. Mahe said, "The picture was at my desk in the world Trade Center, Tower Two, on the 77th floor. I never thought it could have been kept safe by Keefe for the last 13 years." Mahe said that he was in touch with Keefe over the phone and described the conversation as "dedication and persistence" to continue to seek the owner of the photo. "She kept my photo safe for 13 years in her favorite Ernest Hemingway book, A Moveable Feast." Mahe said he wasn't yet at work as the attacks began on 9/11, and, "thankfully never got a chance to go up to my office." And Mahe's wife has even invited Keefe to Thanksgiving dinner. Now the pair have reconnected with a piece of their past as Keefe has finally returned the picture to its rightful owner and has made a new friend in the process.
