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. 
 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
Solution is here: Yes
Explanation: 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.

Now, solve this: Article: Once upon a time, on an isolated island in the Java sea, lived short people who dominated(, ) the food chain. Standing no more than three and a half feet tall, these human ancestors hunted giant rats, lumbering lizards , and _ elephants. It sounds a bit like a fairy tale, but it's true. Unearthed relics on the island uncovered the remains of a race of tiny human ancestors. Homo floresiensis, as the newly discovered species has been named, apparently could date back to 13,000 years ago. This means they have a lot in common with modern humans. So how and why did these people get so small? Scientists suspect that it's due to the fact that this race lived on an isolated island with limited resources. Take the miniature elephants for example. When elephants first came to the island either by swimming or by some kind of natural land raft, they were probably close to full size. But since there wasn't much to eat, over time smaller elephants lived longer and better. The smaller the elephant was, the less it had to eat to stay strong and healthy. Scientists call this the "island role", and it can apply to humans as well as animals. Given the island's sparse  food supply, it makes sense that the early humans living there would have evolved   a body size requiring less food to survive. So bigger isn't always better. In the floresiensis, at least, getting smaller was the way to go. 
 Question: According to the passage, the fact Homo floresiensis are very small is based on  _  . 
 Options: (A) the islanders in the Java Sea (B) the human ancestors (C) the unearthed relics (D) a newspaper report 
 Asnwer: C
Solution:
Yes
