Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: B
Reason: 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 instance: Article: "It was amazing, just impressive," Holly Budge, a 29-year-old British woman, said after making a safe landing at a spot 12,350 feet (3,765 meters) above sea level -- the highest "drop zone" achieved by a parachutist . "We had one minute of freefall and while we were above the clouds you could see Everest and the other high mountains popping out of the top," she said. Ms Budge and her two fellow daredevils, Wendy Smith, from New Zealand, and Neil Jones, from Canada, jumped out of an aircraft at about 29,500 feet, just higher than the peak of the world's highest mountain. They fell at speeds reaching 140mph, past the highest ridges of the snow-covering Himalayas, before each released a parachute . The jumpers wore oxygen masks to keep their lungs working as they fell. Wearing neoprene underwear was compulsory -- to prevent them from being frozen to death. The adventure, advertised by its organizers as "a feast for those who seek to stimulate all their senses to the full", appeared to have lived up to its billing. "I had never seen so many mountains before," Ms Smith said. "To be on top of the world was simply stunning ." The expedition also offered a way by which to celebrate her 30th birthday later this month, she said. Besides, her jump raised funds for charities in Britain and Nepal, including more than PS10,000 for the Hampshire Autistic Society. In the next few days the feat will be repeated by about 30 others, weather permitting. Each has paid at least PS12,675 to High and Wild, the British adventure travel company behind the project. Ms Budge said: "It was worth the money. It is something that has never been done before."
