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 _ .
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
The answer to this example can be: B
Here is why: 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.

Article: Claude Monet was born on November 14, 1840, in Paris, but he spent most of his childhood in Le Havre, a city of southern France. By the time he was fifteen Monet had become popular as a caricaturist . Through an exhibition of his drawings at a local frame shop in 1858, Monet met the French landscape painter Eugene Louis Boudin, who introduced Monet to outdoor painting, an activity that soon became his life's work. By 1859 Monet had committed himself to a career as an artist and began to spend as much time in Pairs as possible. During the 1860s he met Edouard Manet. With other ambitious French painters, they formed the impressionist school. Working outside, Monet painted simple landscapes and he began to have some success. As his style developed, however, Monet broke one traditional artistic convention after another. His experiments with bright color1 became more and more daring, and he seemed to cut himself off from the possibility of a successful career as a conventional painter supported by the art establishment. In 1874 Monet and his colleagues decided to organize their own exhibition. They called themselves independents, but the press soon labeled them impressionists because one of Monet's paintings had borne the title Impression: Sunrise. Then the name stuck. By the mid-1880s , Monet , generally regarded as the leader of the impressionist school, had achieved significant recognition and financial security. In 1890 he was able to purchase some property in the village of Giverny, not far from Paris, and there be began to construct a water garden--a water lily pond with a Japanese bridge. Beginning in 1906, paintings of the pond and the water lilies occupied his mind for the rest of his life. His famous series Water Lilies, painted between 1990 and 1926, Clearly shows the artist's strong interest in color1 and produces a remarkable visual effect. Despite failing eyesight, Monet continued to paint almost up to the time of his death, on December 5,1926, at Giverny.
