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.

Let me give you an 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.
Question: Researchers did experiments on kids in order to find out _ .

OK. solve this:
Article: It was 1961 and I was in the fifth grade. My marks in school were miserable and, the thing was, I didn't know enough to really care. My older bother and I lived with Mom in an ugly multi-family house in Detroit. We watched TV every night. The background noise of our lives was gunfire and horses' hoofs from "Wagon Train" or "Cheyenne", and laughter from"I Love Lucy", or"Mister Ed".After supper, we'd lie on Mom's bed and stare for hours at the TV screen. But one day Mom changed our world forever. She turned off the TV. Our mother had only been able to get through third grade. But, she was much brighter and smarter than we boys know at the time. She had noticed something in the suburban houses where she cleaned books. So she came home one day, switched off the TV, sat us down and explained that her sons were going to make something of themselves. "You boys are going to read two books every week," she said. "And you're going to write a report on what you read." We moaned(,) and complained about how unfair it was. Besides, we didn't have any books in the house other than Mom's Bible. But she explained that we would go where the books were: "I'll drive you to the library." So pretty soon there were these two peevish boys sitting in her white 1959 Oldsmobile on their way to Detroit Public Library. I wandered reluctantly among the children's books. I loved animals, so when I saw some books that seemed to be about animals, I started leafing through them. The first book I read clear through wasChip the Dam Builder. It was about beavers . For the first time in my life I was lost in another world. No television program had ever taken me so far away from my surroundings as did this virtue visit to a cold stream in a forest and these animals building a home. It didn't dawn on me at the time, but the experience was quite different from watching TV. There were images forming in my mind instead of before my eyes. And I could return to them again and again with the flip of a page. Soon I began to look forward to visiting this quiet sanctuary form my other world. I moved from animals to plants, and then to rocks. Between the covers of all those books were whole worlds, and I was free to go anywhere in them. Along the way a funny thing happened: I started to know things. Teachers started to notice it too. I got to the point where I couldn't wait to get home to my books. Now my older brother is an engineer and I am chief of pediatric neurosurgery at John Hopkins Children's Center in Baltimore. Sometimes I still can't believe my life's journey, from a failing and indifferent student in a Detroit public school to this position, which takes me all over the world to teach and perform critical surgery. But I know when the journey began the day Mom switched off the TV set and put us in her Oldsmobile for that drive to the library.
