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: My daughter Kelly is a cautious person.She needs to warm up to situations,is hesitant to try new things.When with close friends,she becomes a leader who laughs loudly and chants,"Girls rule,boys drool." But when that comfort zone is not around her,she is shy and nervous. This has been challenging for me at times."Shy" is not a word that I think has ever been used to describe me.But this has been a year of firsts for my girl that has filled her with a new sense of confidence.This year she moved to lap lane in swimming where she was preparing for a swim team.This year she learned to ride a bike without training wheels.And this year she completed her first kids' triathlon . On Saturday,with a thunderstorm coming soon and my son's birthday party later in the day,we all went out in the dark of the morning for Kelly to participate in her first triathlon.We practiced transitions from swim to bike to run with her,we got all the equipment she'd need,and we kept talking about the race.But as we waited the two hours for the older kids to finish before her turn,she held my leg a little harder and told me she loved me a few too many times.She was nervous but trying to keep it together. And then it was her turn.From the second she jumped into the water,my heart soared. My daughter transformed into the most confident human being I had ever seen.She dominated that swim,crushed that bike ride and ran to the finish with the biggest smile on her face. I can honestly say that I never felt so proud of someone in my entire life.It wasn't because she did a sport or anything like that.It was because she was afraid of something and conquered that fear with confidence and a fire I hadn't seen before. All day I would find myself just looking over at her and smiling.She might be wearing the finalist medal but I felt like I won that day.I won the chance to see my girl shine. Shine on,sweet baby.
