In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

Example input: Article: Homework can put you in a bad mood , 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.

Q: Article: In a moment of personal crisis, how much help can you expect from a New York taxi driver? I began studying this question and answers are interesting. One morning, I got into three different taxis and announced,"Well,it's my first day back in New York in seven years.I've been in prison."Not a single driver replied,so I tried again."Yeah,I shot a man in Reno."I explained, hoping the driver would ask me why, but nobody asked.The only response came from a Ghanaian driver,"Reno? That is in Nevada?" Taxi drivers were uniform sympathetic when I said I'd just been fired."This is America,"a Haitian driver said."One door is closed.Another is open."He argued against my plan to burn down my boss' s house.A Pakistani driver even turned down a chance to profit from my loss of hope;he refused to take me to the middle of the George Washington Bridge--a $20 trip."Why do you want to go there? Go home and relax.Don't worry.Take a new job." One very hot weekday in July, while wearing a red ski mask and holding a stuffed pillowcase with the word "BANK" on it, I tried calling a taxi five times outside different banks.The driver picked me up every time.My ride with a Haitian driver was typical of the superb assistance I received. "Let's go across the park," I said."I just robbed the bank there.I got $25,000." "$25,000?" he asked. "Yeah,you think it was wrong to take it?" "No, man.I work 8 hours and I don't make almost $70.If I can do that,I will do it too." As we approached 86th and Lexington, I pointed to the Chemical Bank. "Hey,there is another bank,"I said,"Could you wait here a minute while I go inside?" "No,I can't wait.Pay me now." His unwillingness may have had something to do with money--taxi drivers think the rate for waiting time is too low--but I think he wanted me to learn that even a bank robber can't expect unconditional support.
