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.
One 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. 
 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 
 Answer: B
Solution is here: Yes
Explanation: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. Hence, B is the correct answer and output is Yes.

Now, solve this: Article: If English means endless new words,difficult gramrnar and sometimes strange pronunciation,you are wrong.Haven't you noticed that you have become smarter since you started to learn a language? According to a new study by a British university,learning a second language can lead to an increase in your brain power,Researchers found that learning other languages changes grey matter.This is the area of the brain which processes information.It is similar to the way that exercise builds muscles. The study also found the effect is greater,the younger people learn a second language. A team led by Dr Andrea Mechelli,from University College London,took a group of Britons who only spoke English.They were compared with a goup of " _ .''who had learnt a second language before the age of five,as well as a number of later learners. Scans showed that grey matter density in the brain was greater in bilinguals than in people without a second language.But the longer a person waited before mastering a new language,the smaller the difference. "Our findings suggest that the structure of the brain is changed by the experience of learning a second language,"said the scientists. It means that the change itself increases the ability to learn. Professor Dylan Vaughan Jones of the University of Wales has researched the link between bilingualism and maths skills. ''Having two languages gives you two windows on the world and makes the brain more flexible,"he said."You are actually going beyond language and have a better understanding of different ideas." The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34. Reading,writing,and comprehension were all tested.The results showed,that the younger they started to learn,the better."Studying a language means you get an entrance to another world,''explained the scientists.
