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.
One 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.

Now, solve this: Article: Some years ago, on a hot summer day in south Florida, a little boy decided to go for a swim in the cold swimming hole behind his house. In a hurry to dive into the cool water, he did not realize an alligator was swimming towards the shore. His mother in the house, looking out of the window, saw the two as they got closer and closer together. In fear, she ran towards the water, yelling to the son as loudly as she could. It was too late. The alligator reached him. From the dock, the mother grabbed her little boy by the arms just as the alligator got his legs. That began an incredible tug of war between the two. The alligator was much stronger than the mother, but the mother would not let go. A farmer happened to drive by, heard her screams, ran from his truck, and shot the alligator. Amazingly, after weeks and weeks in the hospital, the little boy survived. His leg were extremely scarred by the animal's attack, and on his arms were scratches   from mothers' fingernails where she had tried to hang on to the son she loved. The newspaper reporter who interviewed the boy asked if he would show him his scars. The boy lifted his pant legs . And then, he proudly said to the reporter: "But look at my arms. I have great scars on my arms, too. I have them because my mom would not let go." You and I can identify with   that little boy. We have scars, too. No, not from alligator, or anything quite so dramatic . But the scars of a painful past. Some of those scares are ugly and have caused us deep regret. But some wounds, my friend, are because someone has refused to let go. In your struggle, maybe someone has been there holding on to you.
