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: My first performance in front of an audience was coming up soon. I tried as hard as I could to keep calm, but my heart was racing. I stared down at my sweat-covered, shaking hands. I looked up again at the audience, realizing that these were real people. They were not just my mum and dad, who would say, "Good job!" even if I missed up the whole piece. What if I had the wrong music? What if I played the wrong notes? As it turned out, I was never able to answer these questions because the spotlight   was waiting for me. I grasped my hands tightly together, drying off the sweat. Slowly I walked to the mud-brown piano in the centre of the room. It had 88  _ keys, which were waiting impatiently to be played. _ in my throat   and sat down. Slowly, I opened the music. Next, I rested my still shaking hands on the keys. As my fingers played across the keys, I was becoming more unsure of my preparation for this moment. But the memory of my year of training came flooding back. I knew that I had practised this piece so many times that I could play it backwards if asked. Although at one point I accidently played two keys instead of the intended one, I continued to move my fingers automatically . My eyes burned holes into the page in front of me. There was no way that I was going to lose my concentration. To keep this promise to myself, I leaned forward and concentrated carefully on the music. When I came to the end of the page, a warning went off inside my head: don't make a mistake when you turn the page! Needless to say, I obeyed myself with all my heart and mind, and was proud of my "page-turning" feat . I finished the rest of the piece without making a single mistake. I had finished. I had mastered the impossible.
