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.
One 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.

Now, solve this: Article: Musa Kayairanga of Rwanda is a traditional healer. He uses natural medicines to treat his patients. He learned how to use computers at a rural telecommunications center in his country. Musa Kayairanga says he exchanges information with doctors as far away as Canada. He also says the computer has improved his knowledge of using plants to treat diseases. Many people in rural areas are now able to communicate with the rest of the world. This is one example of how technology is changing life in developing countries. Andrew Burns is an economist at the World Bank in Washington, D.C. He led a recent study of technology in developing countries. The study found that technology has spread faster in such countries than in rich nations. It also found that technological progress has helped raise wages in developing countries. And it reduced the percentage of people living in extreme poverty from twenty-nine percent in 1990 to eighteen percent in 2004. Progress in communications technology has aided the growth of call centers in developing countries. Call centers are offices where most telephone calls for a business can be answered. For example, a woman in the United States who calls her computer company about a problem might speak with someone in India or Pakistan. Call centers serve businesses in local and international markets. And they have added to economic growth by providing well-paid jobs and new skills for workers who might not have had such employment. Ahsan Saeed is a young call center worker in Karachi, Pakistan. He says the job improves his language skills, his sales skills and his ability to deal with people.( from VOA Special English )
