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: When you don't speak, you may be still communicating. It is true that you may not wish to say anything. But your very silence may show your wish to be left alone or to stay uninvolved, which is the message you want to send. So it has been said that while we speak with our vocal organs, we  _ with our whole bodies. All of us communicate with one anther nonverbally  , as well as with words. Sometimes we know what we are doing with the use of gestures such as the thumbs-up sign to indicate that we approve. But most of the time we are not aware that we are doing it.  Body language serves a variety of purpose. Firstly it can replace verbal communication, as with the use of gesture. Secondly, it can modify   verbal communication. Loudness and tone of voice is an example here. Thirdly it regulates social interaction: turn taking is largely governed by non-verbal signals. Fourthly it conveys our emotions. Finally it conveys our attitude towards ourselves and towards the people we are communicating with.  _ is particularly important for successful cross-cultural communications. Every culture has its own body language. So in order to achieve a more successful cross-cultural communications, we heed not only what to say but also how to say it appropriately. Observation shows that a truly bilingual person switches his body language at the same time he switches language.
