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: Sports are the base of my life, next to my mother who raised me when my dad left us.I have been into sports since I was six years old.I have known many coaches and heard hundreds of their tips, but they usually focused on drills to develop my skills and reach the next level of play. When I was in Senior Two, I met the new school basketball coach, Brian Pawloski.I thought I was certain to be selected for the school team since I had been in it the year before.I showed up to the tryouts and put out about 90% effort since I thought I'd make it with no problem.That was a big mistake. Brian Pawloski is the hardest      working coach I have ever met.He didn't expect 100% effort, he expected 200% effort.One example: he once made us do 40 suicide drills for the 40 lay      ups   we missed in a game.Some think this is crazy, but it isn't.After this conditioning practice, as we were getting a cup of cold water to drink, I said, "coach, that was the best practice I ever had." I was completely sincere.This man was and is the person who influenced me most at my high school.He expects us to be excellent not just on the court but in the classroom.If I am not working on basketball, I am reading a book that he thinks will help us better understand life's challenges, including Wooden, Coach, and The Screwtape Letters. In the first two years I slacked off, not putting forth my full potential.Now, unlike the coaches of my youth, this man was interested in how he did off the court.He always made sure I kept up with my studies and was able to be trusted.I can honestly say that no other coach has given me so much advice on how to succeed in basketball, but more importantly, in life.My school is lucky to have such a great person to teach, coach and influence their students.I will always remember my high      school basketball days as one of the hardest times I have ever worked in my life not only in basketball but in my growth as an individual. 
 Question: Different from other coaches, Coach Brian   _  .

C
