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.

Problem: Article: J.K. Rowling set children's imaginations on fire. Can the creator of Harry Potter do the same for a grown-up audience? The British author will find out on September 27, when more than 2 million hardcover  copies of her first novel for adults hit bookstores in the UK and the US, along with the digital edition. Set in a little English town, The Casual Vacancy is about an election held after an unexpected death. Michael Pietsch, Rowling's US publisher, says the novel reminded him of Dickens "because of the humanity, the humor, the social concerns, the intensely real characters". No magic though, apparently: "This book isn't Harry Potter", says Pietsch. "It is a completely different concern". As with Harry Potter, there are no advance copies for the media, no early reviews. To date, the seven-book series has sold more than 450 million copies worldwide, and it became one of the most successful movie franchises in July 21, 2007. Back then, fans could buy books at midnight parties hosted by bookstores. But recent years have seen a great challenge for brick-and-mortar  bookstores. People are still buying books, indeed more books than in 2007, according to figures released by the Association of American Publishers. But they are reading them in a new format --the e-book. The Harry Potter series just became available digitally for the first time in April. It will be different for The Casual Vacancy, with the publisher _ releasing an e-book. For Rowling fans who once queued up for Harry Potter, this means that instant satisfaction is now only a click away. Moving from children's books to adult literature is a big transition. Will Rowling's new book be successful? Arthur Levine, the US co-editor of the Harry Potter books, seems confident: "If you read or re-read the Harry Potter books, you can see that Rowling has all the strengths she needs for great success as a fiction writer -you have great characters, an involving plot, a sense of humor and great empathy". 
 Question: What do the Harry Potter series and The Casual Vacancy have in common? 
 Options: (A) They are both intended for children. (B) They both show the author's great talent. (C) Their characters both have magical power. (D) Both of them won't be read on the Internet. 
 Asnwer: B

Solution: Yes
