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: I took the bus to work for many years. No one knew each other; the passengers all sat there sleepily in the morning. The bus was cheerless and silent. One of the passengers was a small gray-haired man who took the bus to the center for senior citizens every morning. No one ever paid very much attention to him. One July morning he said good morning to the driver and smiled. The driver nodded guardedly . The rest of us were silent. The next day, the old man boarded with a big smile and said in a loud voice: "A very good morning to you all!" Some of us looked up, amazed, and murmured "Good Morning" in reply. The following weeks, our friend was dressed in a nice old suit and tie. His thin hair had been carefully combed. He said good morning to us every day and we gradually began to nod and talk to each other. One morning he even had a bunch of wild flowers in his hand. The driver turned around smiling and asked: "Have you got yourself a girlfriend, Charlie?" We never got to know if his name really was "Charlie", but he nodded shyly and said yes. The other passengers whistled and clapped at him. Charlie waved the flowers before he sat down on his seat. Every morning after that Charlie always brought flowers. Some passengers also brought flowers for him. The bus became a happy place. Then, one morning, as autumn was closing in, Charlie wasn't waiting at his usual stop. When he wasn't there the next day and the day after that, we started wondering if he was sick or--hopefully - on holiday somewhere. When we came nearer to the center for senior citizens, one of the passengers asked the driver to wait. We all held our breaths when he went to the door. The old gentle man was fine, but one of his close friends had died over the weekend. How silent we were the rest of the way to work. The next Monday Charlie was waiting at the stop, stooping   a bit more, a little bit more gray, and without a tie. Inside the bus was silent. Even though no one had talked about it, all of us sat there silently, our eyes filled with tears and a bunch of wild flowers in our hands.
