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: It was a physical class. But it was nothing like previous ones -- the class was "attended" by over 60 million students across China, and the teacher was not even on the planet: she was 340 kilometers above the earth. "Hello, everyone. I'm Wang Yaping. I'll host your lecture today." Smiling to the camera, Wang, China's second female astronaut, started her video class on June 20 on board the Tiangong-1 space station. To show how Newton's Laws work in space, Wang and her fellow astronauts used simple items like balls and spinning tops. The highlight of the lecture was when Wang _ using a metal ring, something that only happens in zero gravity, where the surface tension  of water is much higher than it is on the earth. She then took it a step further by pouring more water onto the film and turning it into a water ball, leaving the audience amazed by what they saw. The 40-minute lesson seemed to have passed too quickly for students to see enough of those magical experiments. But sending stuff into space is really expensive. According to The Beijing Times, every kilogram launched into space cost 20,000 dollars. The experimental items taken this time were all strictly selected and weighed about 2.9 kilograms in total. This adds up to quite a large price tag. The organizers of the event also had to consider the time of day: the communication signal between the earth and Tiangong-1 was best during that specific 40 minutes, when the spacecraft was flying within the coverage of all of the ground-based testing stations. 
 Question: Why is the class different from a common one? 
 Options: (A) Because it took 40 minutes. (B) Because over 60 million students across the world attended it. (C) Because the teacher was on the planet. (D) Because the lecturer was in space. 
 Asnwer: D
Solution:
Yes
