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: Tang Zhou and his wife are planning to have their second child, a test-tube baby. His wife had a natural delivery when she was 34 and their first child, a boy, is now 7. The couple are now hoping to have a daughter through _ in the US. "My wife couldn't bear another delivery because of her heart condition and her age. Surrogacy helps avoid the risks to older mothers," Tang said, "Moreover, our second child will be born in the US and become a citizen there. That is not a bad choice." The couple spent weeks researching their move, looking for a reliable agency that provides surrogacy services overseas. Surrogacy is still illegal in many countries, including China. "We will be taking much higher risks by relying on a surrogate mother in China because we are not protected by any regulation or law. You pay a lot of money but may meet with many problems," Tang said. "You might not even get your baby back." Tang and his wife are part of an increasing number of Chinese couples who are turning to surrogacy services. Tang also considered surrogacy in Thailand but dropped the idea after recent reports about a baby with Down Syndrome who was delivered through surrogacy and said to have been deserted in Thailand by the biological parents from Australia. Instead, Tang chose the California Surrogacy Center agency as his first option after reading the detailed introduction on its website. Compared with many other agencies that he could contact only via e-mail, the center has a consulting office in Beijing, Tang said. The center is in San Diego, California, and has satellite offices in Los Angeles and Beijing. According to Liu, the center has been operating for more than eight years, and about 100 surrogate mothers live in California.
