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.

Problem: Article: "I don't want to write a story about girls!I don't know anything about girls."Louisa May Alcott told her publisher,Mr Niles.But she was desperate for money.She seemed to be the only one in her family who could make some money.Niles had asked her to write something she knew,instead of the romantic adventure stories she had been writing."So I plod away,"Alcott wrote,"though I don't enjoy this sort of thing."It was 1867,and the horrible Civil War was over.Now Alcott could turn her energy to making money. Alcott wrote a simple story of life in her family,their pillow fights on Saturday nights and the amateur plays they performed."Our experiences may prove interesting,though I doubt it."("Good joke."she wrote years later.)Her book described her days growing up with four sisters in a family that had no money.She sketched a loving mother who took time to be interested in each child,and she told of the death of a beloved sister.She portrayed her family and friends in her book Little Women.Finally,in July of 1868,she finished writing.With a sigh and a headache,she sent off all 102 handwritten pages of her book. Niles thought the book was dull,and so did Alcott.But when she received her copies of the book,Alcott thought it seemed better than expected."Not a bit sensational,"she wrote,"but simple and true.We really loved most of it."Niles asked some girls to read Little Women,and they loved it.If girls liked it,Alcott was satisfied. In three months,all the copies of Little Women had been sold out.It was already time to print more books!Niles thought she could sell three or four hundred more copies."An honest publisher and a lucky author made a dull book into a golden egg for ugly ducking,"Alcott wrote in 1885.Later,with a great sign of relief,she was able to write,"Paid off all the debts!Now I feel that I could die in peace.If my head holds out,I'll do all I hoped to do."
