Teacher: In this task, you're given an article, a question which often contains a blank, four options (associated with "A", "B", "C", "D") and the answer to that question. Your task is to classify whether the given answer is correct or not by providing "Yes" or "No", based on the article.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Article: Homework can put you in a badmood , 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 _ .

Now, solve this instance: Article: Melissa Poe was 9 years old when she began a campaign for a cleaner environment by writing a letter to the then President Bush. Through her on efforts, her letter was reproduced on over 250 donated billboards  across the country.

There are now 300,000 members of Kids F.A.C.E. worldwide and it is the world's largest youth environmental organization.  Poe has also asked the National Park Service to carry out a "Children's Forest" project in every national park. In 1992, she was invited one of only six children in the world to speak at the Earth Summit in prefix = st1 /Brazilas part of the Voices of the future Program. In 1993, she was given a Caring Award for her efforts by the Caring Institute. Since the organization started, Kids F.A.C.E. members have distributed and planted over 1 million trees! Ongoing tree-planting projects include Kids' Yards -- the creation of backyard wildlife habitats   and now Kids F.A.C.E. is involved in the exciting Odyssey, which is a great way to start helping.   "We try to tell kids that it's not OK to be lazy," she explains, "You need to start being a response, environmentally friendly person now, right now, before you become a resource-sucking adult." 
 Question: Kids F.A.C.E. is   _  . 
 Options: (A) a program to help students with writing (B) a project of litter recycling (C) a campaign launched by President Bush (D) a club of environmental protection 
 Asnwer: D
Student:
