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.

Explanation: 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.

Now, solve this: Article: The day the letter arrived from my university telling me how much I owed them for my first semester, I felt a lump forming in my throat. I hadn't even started my degree and already I was in debt. But although the sum was unsettling, I had peace of mind: I had taken out a loan that would cover the next three years of tuition fees and living expenses. A government body in the UK, the Student Loans Company, provides loans to students whose parents cannot afford to cover the costs themselves. Students forward this amount to the university in advance and agree to repay the loan when they begin their first job. For me, it was a lot of money -around &6,000(60,860 Yuan) per year in total -and much more than I had ever been responsible for. I would receive a couple of thousand pounds per semester -half for tuition fees, half for living costs. Even though I will be paying off my debt for a long time, I don't regret my decision. Having a loan taught me a lot about money management, which I would not have learned otherwise. Each term I paid my tuition fees in one payment, but I also received my loan for living costs in one payment. It was up to me to organize how I would spend this. I divided the amount to calculate my weekly budget and it was important that I tried not to overspend. I had to be disciplined and keep a close eye on my expenditure. Food, clothes and going out are the main things students spend money on. With a loan, students have total financial freedom. Instead of having someone looking over their shoulder, they must make every financial decision for themselves. This year, university fees were tripled. But when it comes to money management, perhaps this generation will be the smartest yet.
