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: People in China, as in other parts of the world, are waiting to see how U.S. President-elect Barack Obama will deal with global problems such as the current economic slowdown once he takes office. As Sam Beattie reports from Beijing, there is widespread hope for closer U.S.-Chinese cooperation. For many students in Beijing, Mr. Obama symbolizes all that is possible in the United States. He's a popular winner here, seen as a self-made man who has made it to the top. "I think he is very charming, and a president who can create a new era," said Zhang Wei, a university student. "I like him very much and most of my friends do too." Ni Weibo, another university student, agrees. "Sino-U.S. relations still need more cooperation," she said. "I think he will help take it to a new era." China's President Hu Jintao congratulated Mr. Obama within hours of his victory, saying he hoped bilateral ties could be made stronger. Political analysts here say China will be looking for the incoming president to avoid contentious issues such as Taiwan's independence, human rights and Tibet. Instead, they say Beijing would like Mr. Obama to focus on solving the global economic crisis, and to help China's slowing economy by opening up U.S. markets. But trade relations might be _ , says Renmin University's Professor of International Studies, Shi Yinhong. He warns, "There is a possibility that President Obama will take some protectionist measures which China will not accept, then trade disputes could develop to a degree that we have not seen ever before." Despite making the headlines, Mr. Obama faces some tough challenges in managing the U.S. relationship with China. China is now a stronger and more confident country than the China his predecessors dealt with. And in this time of economic uncertainty, analysts say it's a country with which Mr. Obama will want to maintain a good relationship.
