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.

Now, solve this: Article: Japan's All Nippon Airways, which has asked passengers to visit the toilet before boarding to help the environment, said Tuesday it will fit its jets with a women-only lavatory . ANA will introduce one female-only toilet per aircraft on international flights next month after a survey of women fliers identified  it was the second most attractive service they wished for after being offered desserts. The rest of the toilets onboard will be for men and women as usual. "We received many comments that having a women-only lavatory would be a factor in differentiating our airline from others," said an NAN spokesman. "Many women said that they feel uncomfortable taking their time in the lavatory knowing that a male is waiting just behind them in line," he said. The spokesman denied that the new service was introduced following complaints about men soiling  the bathrooms, telling reporters: "Those opinions may exist, but we do not have that data on hand". Since 2006 ANA has pursued   a one - month awareness campaign each year in which it asks fliers on 38 flights and four international flights to visit the bathroom before boarding to reduce their body weight and therefore cut he plane's carbon-dioxide emissions. The airline is also planning to install "washlets" in it's aircraft-electric toilet seats with water sprays for washing-a common sight in Japan and generally a source of amusement for first-time visitors and users. The "washlets" will be installed in the Boeing777-300ER,due to begin operating in April, and the Boeing 787 fleet set to start flying this year.
