Given the task definition, example input & output, solve the new input case.
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.
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
Output: B
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.

New input case for you: Article: If you're still of the belief thaJ mental health conditions aren,t as serious as physical ones,a new report will open your eyes. The United States spent about $201 billion on mental illness in 2013, according to the new analysis published in the journal Health Affairs. That makes it the costliest medical condition in the country. Heart conditions were the second costliest condition, falling far behind menial disorders at $147 billion. Trauma and injury was third at $143 billion. "One key finding of this study is the degree to which spending on mental health disorders in 2013 topped those on all other medical conditions, including heart conditions, trauma, and cancer. Researcher Charles Roehrig wrote in the study's conclusion. Just a decade ago, heart conditions outweighed mentd disorders. Health care costs on heart Problems were about $105 Million in 1996, with mental disordere coming in second at $79 billion. The findings are just another example of how important it is to recognize mental illness as a widespread public health issue. Nearly one in four people will experience a mental health condition at some point in his or her life. Despite this fact, though, there's still a lack of sensitivity and understanding in society--and even the medical community--when it comes to mental disorders. Research shows discrimination involved in mental health. Negative thoughts surrounding mental illness often prevent people from seeking treatment, which can have serious consequences. Data also suggests that not paying attention to mental illness can affeci a company 's bottom line. Serious mental illnesses result in about $193 billion in lost earnings per year. Lastly, the cost of mental health issues extends beyond a dollar sign, but perhaps the shocking figure in the report will finally serve as a wakeup call for those who believe psychological conditions aren't real issues. In other words, can we please take mental illness seriously now?
