Given the task definition, example input & output, solve the new input case.
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.

New input case for you: Article: My decision to travel around China lay merely with my curiosity about the place. Before coming here, China seemed _ to me ----a place that expected to be hugely dissimilar from my own British culture. After travelling from Beijing up to Xi'an, I wanted to challenge myself by choosing a smaller town----Xiahe in Gansu Province. I arrived in Lanzhou at around 5 am, but there were no buses to Xiahe. I managed to spot a policeman and attempted to explain my destination to him in simple English, praying that he would understand. I wasn't sure that he did but I just followed him anyway as I had no choice. He took me on a bus and I didn't know where I was going. Luckily, I met a student who explained to me in English that the policeman was taking me to another bus station where I could take a bus to Xiahe. During this conversation a third man said he was also a policeman and would help me buy tickets. But as he was not in uniform, I was a little doubtful. The uniformed policeman told me it was OK to go with the third man, so I got off the bus with the so-called policeman who at this point, disappeared and I was left in the middle of nowhere. I stood panicking. Around one minute later a police car came and stopped right by me. It was the un-uniformed policeman. I got into the car and he dropped me directly at the bus station, and helped me buy the ticket. This is one of many experiences that I have had in China. I realized that however different this culture was, there was one thing that would always stand out--kindness. In the west we seem to lack the foundation of trust, yet in China it seems that there will always be someone to answer your questions and lead you the right way.
