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.
One 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.

Now, solve this: Article: While elephants are respected by the people of Thailand, they are also used as beasts of burdens  . Today, these majestic animals are extensively used to help carry wood for the logging industry. It is therefore nice to hear that on National Elephant Day the mighty mammals are treated like a king, and served with meals fit for a king. One of the biggest celebrations took place at the Pattaya Resort in Thailand's Chonburi Province. Fifty-two elephants, some wearing beautiful clothes, arrived bright and early   for the big day. Each was first blessed with holy water by a professional elephant rider and then led to the grand feast, which served an unlimited supply of their favorite treats--bananas, dragon fruits  , pineapples, assorted melons, apples and the list went on and on! The elephants ate till they were satisfied before walking back with their owners for a good night's rest. Though called National Elephant Day, the celebrations that took place on March 13th this year stretched out for an entire week. Besides providing a well-deserved treat and break for the hard-working animals, the celebrations were also aimed to raise awareness about the mammal's dwindling   population. One smart elephant even helped show the message by painting a dead elephant and the words "Don't kill me", right beside _ . And horrible as the message may sound, there is a sad ring of truth to it. Since the 1900s the number of elephants in Thailand has gone from over 100,000 to just 3,000-4,000 because of the destruction of their natural habitat and illegal killing. Asian elephants are not the only ones that are in trouble. African elephants are facing the same fate  . Hopefully, the public and officials are now working together to save these mighty animals from disappearing from the world.
