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 _ .

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: Bill Fulton doesn't remember losing his wallet, but its return helped him remember the past. The leather stayed smooth and the cowboy design unblemished  . And when he looked inside, the contents brought back memories from 1946, when he apparently dropped the wallet behind the balcony bleachers   in the Baker Middle School gym. Fulton's Social Security Card and bicycle license, bearing the address where he lived during his teenage years, were positioned in their respective compartments, apparently untouched since the year after World War Il ended. Worker Nathan Osborne found the wallet -- along with old homework, lost library books and a 1964 talent show program -- while removing the bleachers for renovations on June 17. It was brought to Fulton's door the following day by Melanie Trindle, the Baker Middle School secretary. Middle School Principal Mindi Vaughan said the brown pine bleachers were connected to the gym balcony's brick wall and had remained in the same place since the school, known as the Helen M. Stack Building, opened in 1936. Fulton, 78, said he probably lost the wallet while cheering for the Baker High basketball team with a group of friends. Fulton said the bicycle ID was needed because he delivered medicine for Rodamar Drug. He was surprised, however, that his bicycle ID wasn't inside. He said he always kept it there. But rather than focus on what was inside the wallet, Fulton said the recovery has led him to reflect on his life -- one that took him to the Korean War and Berlin before the return to Baker City. He worked at Ellingson Lumber Company for 30 years, from March 1964 to April 1994. Since his retirement, Fulton has enjoyed spending time with his 11-year-old black dog, Smokey. The two often hike the nearby mountains. Trindle's knock on the door, wallet in hand, induced a slight ripple in his life, prompting him to consider the times he hadn't thought about in many years. "Where did all the times go?" Fulton said with a deep sigh. "It' s hard to believe that the times have gone so fast."
