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 _ .

New input case for you: Article: Visitors were still paying 20 yuan to hug Lele and have their photos taken yesterday despite a ban that forbids any such sontact with a wild animal. The ban was introduced more than a week ago. "The city zoo broke the law and should be prohibited," said an official at the State Forestry Administration. The administration notice last Monday clearly bans contact with wild or captive animals, the abuse of wild or captive animals for performance purposes and any improper business related to wild animal products. "Close contact with the chimp is the only bit that breaks the ban and we will end that soon," said Beijing Zoo spokeswoman Ye Minxia yesterday. "The chimpanzee performance can't stopped overnight as we have a contract with a company scheduled to terminate at the end of this year," she said. "The zoo is negotiating with the company in the hope of terminating it sooner," Ye said. She refused to answer directly whether the chimp photo sessions were still ongoing yesterday, instead, saying. "It's very likely we will cancel it tomorrow." Zoo staff confirmed photos were taken yesterday, one employee saying 2-year-old Lele "works" form 10am to 3pm daily, according to the Leagl Mirror. Such activities not only damage the mental and physical health of the animals, but also risk the safety of visitors, according to the official website of the State Forestry Administration where the notice was released. "A pet male chimpanzee bit and attacked 55-year-old Chala Nash, causing serious injuries to her face, neck and hands at her friend's home in Stamfor, Connecticut on February 16th last year," CNN reported. The friend, Sandra Herold, called the police, who shot 14-year-old Travis many times after he also attacked an officer." "Putting a blue T-shirt on a wild animal and training it to bare its teeth and parade for visitors might not enhance that already-troubled image of Chinese animal protection," the State Forestry official warned. "Some zoos even hit animals and promote themselves with commercials involving animal abuse, " he said. "Too much focus on the profits too often results in improper treatment of animals, contributing to their early and unnatural deaths," the notice stated.
