Given the task definition, example input & output, solve the new input case.
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: 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.

New input case for you: Article: Searching for love is no longer just a favorite subject for songs. It has also become a huge industry. Researchers say the online dating industry in the US earned 649 million dollars in 2006. They expect this number to increase to more than 9 million dollars by 2011. Experts say that the industry has grown because traditional social ties have weakened. Many young people leave behind a close community of friends and family to find work in bigger cities. People work longer hours, so they have less time to meet new people. This helps explain the popularity of online dating. Some estimates say120 thousand marriages a year result from matches made on the Internet. The dating industry has also been expanding in new ways. Many companies offer personalized services for finding the perfect mate. These companies are answering a large demand by single people. They are willing to invest their time and money to find love with carefully planned methods, instead of leaving love to chance. AskRomeo is a company in Virginia. It provides single people with advice on how to meet a person for the first time. Also in Virginia, the company True Life Partners provides a more costly and detailed dating service. The company hires a team of professional persons who help couples meet. But this level of service comes at a high price. Men pay thousands of dollars for the service. But women get to take part at no cost. There are lots of other costs linked to dating. And we wonder how the economic recession has affected dating in the US.
