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 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: 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.
Question: Researchers did experiments on kids in order to find out _ .
Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness
Output: B
It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. So, B is the correct answer.

New input case for you: Article: It does not matter who wins. We are told that from day one. Usually, that statement is followed by some remark about being a loser. If we do not care who wins, then why do we compete? Fun, experience, the chance to meet new people --- these are the reasons we try to outdo each other. People will compete over anything. Every Christmas, my neighbors and I have a little Christmas light competition. It is heaven for the electric company, but I think we give Will Rogers Airport a scare. It is bright enough to land a plane in our front yards. I admit that last year my neighbors won, but only because they bought every strand of lights Wal-Mart had before I could get there. Personal competitions are great, but we get a little carried away. I cannot stand to see coaches shout at kids playing sports. Who cares if someone messes up and the other team advances? I'm tired of people competing just to win. It happens not only in sports, but in music competitions, too. People auditioning for chair placement in certain bands can get really unfriendly. This year I did not audition for a certain band, but I went to auditions anyway. This was the first time I actually had the opportunity to comprehend the whole picture. Other times I've been the person who was nervous and anxious. This time, I sat back and observed everyone else. I came to the realization that the people who aren't so good are terrified of the good people, and the good people are scared stiff that the bad people have taken lessons and can now show them up. Unless a person is on the outside looking in, I don't think anyone realizes _ . Maybe competing is human nature, but we shouldn't let it influence our judgment. Being disrespectful to opponents , letting competition become our life, and becoming so involved that we close ourselves off from friends and family is not the meaning of competition. A little competition is healthy, so it shouldn't hurt anyone. If it does, someone somewhere needs to back off, find the good thing hidden inside, and try it again. Winning isn't everything, and losing isn't the end of the world.
