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.

Example input: 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.

Q: Article: Chocolate soap is supposed to be good for the skin. But it's not so good for the tongue. Unfortunately for the US soldiers of World War II, the chocolate bars the army gave them tasted like they were intended for use in the bath. In the army's defense, it wasn't trying to win any cooking awards. In fact, it specifically ordered that its chocolate bars not be too delicious, so soldiers wouldn't eat them too quickly. These bars were created for survival, not taste. "They were awful," John Otto, a former army captain in World War II said, "They were big, thick things, and they weren't any good. I tried them, but I had to be awfully hungry after I tried them once." As unappealing as the chocolate bars were to some, others like them. Samuel Hinkle, the chemist who created the chocolate bars, pointed out that the number of bars made were far greater than the army needed. "It soon became obvious that the generous American soldiers were sharing their valued possessions with their foreign friends, whether soldiers of other countries or local citizens." The bars turned many hungry Europeans into friends of the United States. "People wanted them," said Otto. "You'd give them to kids. In some places they were very hungry. And they surely helped relax people about American soldiers." Otto said he never saw a European _ the chocolate. "It was food," he said. "At that time, everyone was very hungry. I saw German kids standing outside the US army kitchen. They weren't begging, just standing there very politely. When we were done, the kids would eat the food out of the garbage. They were so hungry." Other Europeans did not see chocolate until well after the war ended. "We didn't see any Americans where I was," said Elizabeth Radsma, who was 25 years old when the Germans occupied her country, the Netherlands. "Even after the war, we saw only the British. Maybe the Americans gave out some chocolates in the big cities, but we were only in a small town. Before the British, we saw only German soldiers. But chocolate? Don't make me laugh! Maybe in my dreams!" A soldier in the field might have responded "Be careful what you wish for"--and then gratefully bit on a chocolate bar, the only food available for miles.

Options: (A) The US soldiers used the chocolate bars as bath soap. (B) The US army produced more chocolate bars than necessary for its soldiers. (C) The US soldiers did not have enough food during World War II. (D) European people regretted eating chocolate bars from the US soldiers.
