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.

Let me give you an 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.

Article: Without any previous notice, a documentary dominated headlines and social websites over the weekend. Under the Dome, a 103-minute documentary self-funded by former CCTV news anchor Chai Jing was released on video-sharing websites in China on Feb 28. It has rapidly pushed the public awareness about air pollution and encouraged people to join in efforts to make a difference. Chai, 39, said she started the work out of her "personal clashes" with smog after she gave birth to a daughter. "I sealed tight all the windows. I started every day by checking the air pollution index," Chai said. Millions of other people are also doing the same. While they stop there, Chai goes deeper. "I don't want to live in this way. 1 need to find out where the smog comes from and what on earth is going on." Over a year, she investigated polluted sites to find the sources of smog, visited the US and the UK to learn about their anti-pollution experiences, and interviewed officials, scientists and the general public. Chai's research reveals that the burning of coal and oil contributes to 60 percent of PM2.5 pollutants. She thus questions the country's energy consumption habits in the film. She then goes on to disclose loopholes in car emissions regulations. The film also explains that businesses are pressured not to abide by the laws because violating them carries little or no cost, while making changes bumps up costs. The film also points at China's petroleum and steel industries as the biggest sources of air pollution. Cheng Chen, a 22-year-old student from Beijing Foreign Studies University, found the documentary "very inspiring". "I used to think it's not my duty to deal with air pollution--I don't own a factory or a car," said Cheng. "But Chai told me we share the same fate since we breathe the same air and there is a lot I can do." However, some people are annoyed by the film's description of their polluted hometowns, especially when it shows a banner from Xingtai in Hebei saying "Congratulations to our city for no longer being ranked the last place among the country's 74 cities in terms of air quality". _ "What's important is that Chai's work has raised public attention toward the structure of the energy industry," she said. Meanwhile, experts remind moved viewers of the film's limitations.
