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: Most students hate their endless homework. The students from Class 2, Senior 2 of the High School Affiliated to Peking University certainly did so before they published their own collection of English novels at home. Their small book contains stories about a holy   war, the happy life of a self-taught artist and the story of a laid-off worker who devoted his last breath to playing his beloved accordion  . The book becomes an instant hit on campus. About 3,000 copies have been sold and the class is already working on the second volume. "We're up to our ears in homework. Exercises and exams make us out of breath. But to do something creative and full of imagination is such a great achievement," said Yu Xiaoxiao, 16. "I took the writing as an ordinary homework at the beginning, but after I finished the first part of my story, I could not help but let it flow," said Wang An, who wrote "Accordion". Inspired by "Lord of the Rings", Jiang Lu wrote his story about magic wins between angels from the light and the dark side. "The main message of the story was to look at the balance of the world. Both dark and light angels fight with love as their weapons. I want to tell people that selfish love might bring hate," Jiang said. "I was shocked by their work and felt so proud to be the editor of my students' book," said Nathaniel Timmermann, the oral English teacher at the school. Liu Xiuqin, an English teacher, started the project by asking students to write whatever was in their mind every week. "They have performed beyond expectation," Liu said. "They wrote interesting stories and their English has improved after they started to express their real minds." "We never imagined that our homework would be so popular and profitable  . We sell the novels at five yuan, but many teachers pay more to encourage us," said Yuan Mengyao.
