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: A new international study shows that six people die every minute from smoking. That is 3 million deaths around the world every year. If the present rate of smoking continues, the number of deaths each year from smoking could rise to 10 million by the year 2020.  The study describes smoking is the biggest cause of deadly diseases among grown-ups in industrial countries. So far most of the smoking deaths have happened to men, especially in developing countries.  A researcher at the World Health Organization says 70% of Chinese men smoke more than 15 cigarettes each day. In Latin America about 50% of the men are smokers. There also are a very large number of smokers in Russia and in Eastern Europe. And 25% of all smoking deaths worldwide are in those areas of the world. Scientists say smoking will kill 50% of the smokers.  Smoking is known to cause lung cancer. It also can lead to cancer of the mouth and other parts of bodies. Smokers are more likely than non-smokers to suffer from heart disease.  Experts say that people reduce their chance of dying from smoking if they stop smoking completely. They say smokers who give up smoking can improve their health.
