user: 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, 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.
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 _ . 
 Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness 
 Answer: B
Output: Yes
It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. Hence, B is the correct answer and output is Yes.

New input case for you: Article: (This selection was originally published in 1992. Pluto   is no longer classified as a planet.) Pluto is in many ways the strangest of the planets. It is small and has a large moon(called Charon). Its orbit  is unusual, which may cause it to have seasons in the sense that when it is close to the sun, the liquid  methane on its surface boils to form a kind of atmospheric haze . When the planet moves farther away from the sun, it starts to snow solid  methane. Pluto is not dark. Despite its great distance from the sun, the surface of Pluto is probably as bright as a moonlit night on Earth. The reason is all that methane, which is as white as newly fallen snow. The discovery of Pluto was more accident than design. The American astronomer Percival Lowell had predicted the existence of a ninth planet(he called it Planet X)based on what he took to be irregularities in the orbit of Neptune. Today astronomers argue that these "irregularities" weren't real, but the result of instrumental error. Nevertheless, Lowell produced predictions about where Planet X ought to be(although, to be honest, the predictions changed occasionally when he redid the calculations).In any case, in 1930 Clyde Tombaugh, doing a systemic sky survey that would have found the planet no matter where it was, discovered the planet we now call Pluto. By coincidence, its position was pretty close to where Lowell's last prediction said it should be. Was it just luck? We'll never know. 
 Question: On Pluto's surface, liquid methane boils to form an atmospheric haze, which would be most similar to   _  .
