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 input: 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
Example output: B
Example 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.
Q: Article: Two studies are suggesting that some overweight people do not face an increased risk of developing heart disease. Researchers also found that some individuals of normal body weight have an increased risk of the disease. Being overweight does increase your risk of medical problems, but the studies found that not all heavy people are less healthy than thin people. In one study, American researchers examined medical records from over 5000 men and women. Each person had taken part in a separate study from 1999 to 2004. The searchers found that about 51% of them were overweight or obese. About 32% were obese, but considered metabolically healthy. This means they had no evidence of problems in tests for high blood pressure or other factors linked to heart disease. However, more than 23% of people who were at a healthy weight were unhealthy in two or more aspects Judith WylieRosett helped carry out the American study. She says the finding show that all obese person can still be healthy. She believes that having body fat is not as important as where the fat is found on body. It's reported that twothirds of Americans are considered overweight or obese. A second study is suggesting that fat in the liver may be an important health risk. Norbert Stefan and his team closely examined 314 people.They measured how much body fat each person had, and where it was on the body. To do this ,they used medical imaging tests. They discovered that obese people could have healthy hearts. Their results suggest that fat in the liver is more dangerous than fat in other areas. The results of both studies were published recently in the Archives of Internal Medicine.Professor WylieRosett says the findings don't mean that people shouldn't be concerned about obesity. Experts say there are several diseases linked to obesity that make it more dangerous to be fat than thin. They say people should see their doctor to learn what health risks they may be facing and what behaviours should be changed to improve health.
Question: What was found in 23% of the healthy people examined?
Options: (A) No factors linked to heart disease. (B) They were unhealthy in two or more aspects. (C) High blood pressure. (D) No evidence of problems.
