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.

Let me give you an 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
The answer to this example can be: B
Here is why: 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.

OK. solve this:
Article: Golf in the USA was until quite recently the hobby of old,middle class white men.Not any more.The fact that the class,age and race barriers that existed in the sport have finally been broken down is due almost entirely to two people.Tiger Woods and Michelle Wie. Tiger Woods was born in California in 1975 and is one of the greatest golfers of all time.His ethnic background is marvelously rich and varied.His father Earl was of mixed of black,Chinese and Native American ancestry and his mother Kultida,who was originally from Thailand,also had Chinese and Dutch forefathers. Woods became a professional golfer in 1996 and,less than a year later,astonished the world easily winning the prestigious Masters Colf Tournament,an annual event which takes place at the Augusta Golf Club in Georgia,USA.At 21,he was the youngest golfer ever to win the tournament,but much more important,he was also the first Asian American to do it. Woods'amazing achievement is put into perspective when you realize that until 1990,no non-white American had ever been allowed to join Augusta Golf Club.Even in 2000,it only had two black members.In fact,in 1977,Clifford Roberts,the chairman of the club and founder of the Masters Tournament,proclaimed:"As long as 1 am alive,golfers will be white and caddies will be black."Roberts died not long after making this racist remark... Fortunately,his views were not shared by his successors and the dramatic appearance of Tiger Woods on the Golf scene radically changed attitudes to the sport and prompted a major surge of interest in the game among ethnic minorities end young people in the USA. Michelle Wie,a Korean American born in 1989 whose mother was an amateur golf champion in Korea,will probably became the greatest woman golfer of all time.She's 1.85 meters tall and she can play a golf ball further than most men.Like Woods,she has transformed the world of golf,and wants to do so in even more dramatic ways.She has expressed her determination to play on the men's tournament circuit,not just the women's,and has already appeared in several professional men's tournaments. Thanks to Woods and Wie,golf in America will never be the same again.
