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.
One 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
Solution is here: B
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.

Now, solve this: Article: Anxiety is the appropriate emotion when the immediate personal terror--of a volcano, an arrow, a stab in the back and other disasters, all directed against one's self--disappears. The kind of world that produces anxiety is actually a world of   safety, a world in which no one feels that he himself is facing sudden death. The anxiety exists as an uneasy state of mind, in which one has a feeling that something unspecified and indeterminable may go wrong. If the world seems to be going well, this produces anxiety--for good times may end.If the world is going badly--it may get worse. Anxiety tends to be without focus; the anxious person doesn't know whether to blame himself or other people. He isn't sure whether it is the current year of the administration or a change in climate or the atom bomb that is to blame for this undefined sense of unease. It is clear that we have developed a society which depends on having the right amount of anxiety to make it work...While we agree that too much anxiety is harmful to mental health, we have come to rely on anxiety to push us into seeing a doctor about a symptom which may indicate cancer, into checking up on that old life-insurance policy which may have out-of-date provisions in it, into having a conference with Billy's teacher even though his report card looks all right. People who are anxious enough keep their car insurance up, have the brakes checked, don't take a second drink when they have to drive. People who are too anxious either refuse to go into cars at all--and so complicate the ordinary course of life--or drive so tensely and carefully that they help cause accidents. People who aren't anxious enough take chance after chance, which increases the terrible accidents of the roads.
