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.
One 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.

Now, solve this: Article: Xu Shu was much valued by Liu Bei for his strategic talents. After several victories on the battleground against Cao Cao, Xu was made the chief military advisor. Cao Cao was greatly surprised at the news. "If you want this person," one of his advisors said, "you can bring his mother to Xuchang and send a forged letter in his mother's handwriting, asking Xu Shu to desert Liu Bei and come here. As Xu is well-known for a strong filial  affection, surely he will come." This plot worked. For Xu, on receiving the letter, cried tearfully, asking Liu Bei for an immediate departure. Feeling sad, though, Liu persisted in his stay for another night, during which the two aired their sad feelings. The next day Liu laid a banquet outside the city for Xu. Holding the latter's hand, Liu said,  "After we separate today, only heaven knows when and where we will meet again." He wept bitter tears. After setting off on his way, Xu suddenly turned his horse and returned. "I almost forgot an important matter." He said to Liu. "Ten kilometers from Xiangyang City, in a place called Long zhong, there is a talent called Zhuge Liang. Do you want to meet him?" Liu expressed his willingness at once, but also aired doubt about whether Zhuge Liang was as talented as Xu. "He tells positions of stars in the heavens," Xu assured him, "and recognizes everything on earth. He knows a person's real nature at the first meeting----the number one talent under the heaven. If you have him as your military advisor, you'll have the country under your name." Liu suggested a visit to Zhuge by Xu on his behalf. At this, the latter shook his head in disapproval. "You must go and offer your invitation personally, and his acceptance depends entirely on your sincerity." With these words said, Xu turned his horse and left. Later, Liu paid three trips to Zhuge's straw house, another favorite story among Chinese people.
