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: The Lunar New Year, which starts in late January this year, is the most important festival for Chinese people as most of them drop any business at hand to go back to their hometown to see their families. It is a tradition that has been cherished since ancient times, but as social mobility increases in modern times, the road to family reunions has become very uneasy. It is not the higher travel costs, nor the expected big spending on gifts and other festival items, but the train ticket that has driven many travelers mad. I've heard some colleagues complain that they have tried every means to secure a train ticket, only to find it a mission impossible. Some of them have turned to the latest software to aid online booking; others have sought help from friends to increase the possibility of successful booking. No doubt chunyun, the Spring Festival travel season, is the largest-scale annual human migration in the world. Last year, 220 million passengers traveled by train during the Spring Festival season, which usually lasts 40 days. It is a huge jump from 10 years ago, when the number was 128 million. With the big sudden increase in demand, the railway company has increased investment in railway construction; still, it cannot bridge the supply gap, leading to fierce public complaints and criticism. Admittedly, it is almost impossible for the railway company to suddenly improve its capacity to meet the explosive demand during the Spring Festival holiday. Moreover, any temporary increase in capacity would become unnecessary after the holiday and mean great commercial losses during the off season. What the company can reasonably do is gradually improve its capacity while focusing on better distribution of its existing resources during the special peak season. At any rate, however, the problem cannot be solved overnight. 
 Question: Compared with ten years ago, the percentage of passengers last year increased by  _  . 
 Options: (A) 40% (B) 58% (C) 71% (D) 83% 
 Asnwer: B

Solution: No
