In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.
Example: Article: Homework can put you in a badmood , 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: Since the 1950s, most of the stars of pop music have come from Britain and America. Howver, in the last ten years, when many different kinds of music have established themselves on the pop scene, more and more stars have come from other countries. Pop music changes all the time and new stars appear and become famous. For a musician to stay popular and still produced good, original music over a long period of time, is a sign of true star. Most stars start their careers in a simple way---- playing in unknown night clubs or dance-hall where people want to dance to the music, not listen to it. They may have continued doing this for many years untill they get a "break"---- a chance to perform in a well -known place or get a recording contract. To become a star is the aim of every singer or musician and the dream of many a pop-crazy teenager. However a group or star makes it to the top, they can be sure that their lives will change once they are successful. Ordinary teenagers living at home with their parents may suddenly find themselves rich enough to buy their own houses. An established superstar may be able to buy several. Despite the large amount of money that are earned, life at the top is not easy for many stars.. The pop scene is hard work and many stars need to spend a lot of time away from home. For a lot of them, this means they have no home life and their personal relationships suffer. Despite great public success, life at the top can be very lonely.
