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: New York's streets were covered by people dressed in elephant costumes   and others waving antiwar posters with pictures of US President George W. Bush on them last week. But this was no carnival   - it was the Republican Party's National Convention  , which attracted thousands of protestors  . It was the largest protest ever at a US political convention, with at least 120,000 people marching through Manhattan on August 29. They demanded that the US leave Iraq and a new president be chosen. The Republicans say the opposition - Democrat Party   encouraged the people on to the streets. They believe it is a democratic move to help win presidential election, to be held on November 2. The election is described as "the decisive battle between donkey and elephant". The two animals are the symbols of the two major political parties in the US. The elephant represents   the Republicans, whose candidate  , President George W. Bush, is trying to defeat the donkey to win his second them. The donkey represents the democrats, whose candidate, John Kerry, is trying to kick the elephant out of the White House. Republicans think the elephant is powerful and clever, but the Democrats argue it is stupid and conservative  . In return, the Republicans regard the donkey as stubborn   and silly but the Democrats say it is humble, plain, smart and courageous. The Republicans have been sending emails to Bush supporters and journalists with the heading, "An Elephant Never Forgets", said party spokeswoman Heather Layman. Elephants are known for their long memories. The emails suggest that Bush will keep his promises, while Kerry will not stick to his words. It is interesting that both symbols were created by a single person, Thomas Nast, a famous political cartoonist of the late 19th century. During the election in 1874, Nast drew a cartoon, in which a donkey in a lion's skin frightened an elephant marked "Republican". 
 Question: What does "kick the elephant out of the White House" mean? 
 Options: (A) Drive the animal out of the White House. (B) Drive President Bush out of power. (C) Keep the elephant out of the White House. (D) Insist on Bush's being elected. 
 Asnwer: D
Solution:
No
