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: The world's earliest known fish hooks   show that humans fished in the open sea for much longer than previously thought. Past studies have shown that early humans were able to cross the open ocean as far back as 50,000 years ago, but evidence that they could fish while in the open sea dated back only to 12,000 years ago.               "In most areas of the world, evidence for our early ancestors' coastal exploitation   was drowned by rising sea level," said researcher Sue O'Connor.               Now O'Connor and her colleagues have found evidence of prehistoric fishing tools and the remains of large fish such as tuna    at a cave shelter known as Jerimalai, located in the Southeast Asian island nation of East Timor. Their discovery uncovered fishing hooks made from bone that dated back to about 42,000 years ago.               "It's possible that people caught the tuna in the deep channel that lies off the coast of the Jerimalai shelter," O'Connor said.               The site, first uncovered in 2005, also included bone points, shell beads, the remains of fish, turtles, bats and birds, and nearly 10,000 stone tools. The island of Timor has very few land animals overall and only small birds call the island home, perhaps explaining why the ancient people here went fishing. About half the fish remains at the site came from fish such as tuna. Catching such fast-moving fish requires much planning and complex technology, suggesting that early humans developed these skills earlier than previously thought.               Some other scientists might say that most of the fish bones seen are from young fish, and thus might have been caught more easily off the coast as opposed to in open waters. While this may be the case, it's still not easy to catch tuna -- it requires nets set in deep water. 
 Question: According to Sue O'Connor, evidence for our early ancestors' coastal exploitation   _  . 
 Options: (A) indicated tuna was a common dish for our early ancestors (B) showed the trend of sea movement (C) was difficult to find (D) was buried in cave shelters 
 Asnwer: C
Solution:
Yes
