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.
Question: Researchers did experiments on kids in order to find out _ .
Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness
Example solution: B
Example 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.

Problem: Article: Mark Rothko, one of the greatest painters of the twentieth century, was born in Daugavpils, Latvia in 1903. His family immigrated to the United States in 1913, after a 12-day voyage. Mark moved to New York in the autumn of 1923 and found employment in the garment trade and settled down on the Upper West Side. It was while he was visiting someone at the Art Students League that he saw students painting a model. According to him, this was the start of his life as an artist. He was twenty years old and had taken some art lessons at school, so his initial experience was far from an immediate calling. In 1936, Mark Rothko began writing a book, which he never completed, about the similarities in the children's art and the work of modern painters. The work of modernists, which was influenced by primitive art, could, according to him, be compared to that of children in that "Child art transforms itself into primitivism, which is only the child producing a copy of himself." In this same work, he said that "The fact that one usually begins with drawing is already academic. We start with colour." It was not long before his multiform developed into the style he is remembered for. In 1949 Rothko exhibited these new works at the Betty Parsons Gallery. For reviewer Harold Rosenberg, the paintings were unique and primitive. Rothko had, after painting his first multiform, separated himself from the world in East Hampton on Long Island, only inviting a very few people, including Rosenberg, to view the new paintings. The discovery of his works' specialty came at a period of great sorrow: his mother Kate died in October 1948. As part of this new uniformity of artistic vision, his paintings no longer had individual titles. From this point on they were simply untitled, numbered or dated. However, to assist in distinguishing one work from another, traders would sometimes add the primary colours to the name. Additionally, for the next few years, Rothko painted in oil only on large vertical tents. This was done to surround the viewer, or, in his words, to make the viewer feel enveloped within the picture.
Question: What did Rothko think of modern art?
Options: (A) It could be produced by children. (B) It could be compared to child work. (C) It was a certain kind of primitive art. (D) It was academic from the very beginning.
Solution: B
