Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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: Yes
Reason: 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 instance: Article: Every small child knows the panic of losing sight of its mother in the supermarket, and as these delightful pictures show, small whales obviously feel the same way. Taken by a British diver who was following the sperm whale calf, _ show the minute the baby - who had lost track of its mum - found her again in the sea off the Azores. Soaring 30ft across the waves, the newborn slammed its body onto the water with joy after becoming separated from its family group in the chilly waters. But the whale calf was doing more than just jumping for joy. British biologist and dive guide Justin Hart, 44, who took the pictures, says that young whales communicate with older ones in the ocean by creating a slamming sound which travels through the water to the ears of the adults deep below. By leaping out of the water and slamming its 12ft long body onto the surface of the sea up to 30 times, the baby whale is telling its relatives where it is so they can regroup. He said: "We had been following the sperm whale calf for most of the day. Sperm whales, of all the whales and dolphins, are the species that dive the deepest and for the longest time." "The calves have to follow what's going on below them from the surface as best they can probably listening to the echo location clicks of the adults." "However, sometimes the adults re-surface far out of sight of the calf, and in this situation the whales often leap out of the water causing a large bang as their bodies hit the surface. In this way, the whale family could regroup." He added: "When I took the photo, two adults' females had just resurfaced and the calf quite literally began jumping for joy." Mr. Hart captured the rare image four miles from the port of Lajes do Pico while he was working as a crewman on an underwater documentary with special license to film sperm whales in the area. Sperm whales live in nearly all the world's oceans in groups of about 15 to 20 animals and they practice communal childcare. The calves do not have to follow their mother too closely as sperm whales can take milk from any milk-producing female in its social group.
