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: 2010 was a good year for American farmers. They earned about eighty-two billion dollars. That is almost one-third more than that they earned last year. And it is twenty-six percent higher than the ten-year average. Values for grain and oilseed crops are up about three percent from last year. The value of animal production is up by almost seven percent. In 2011, farm exports are expected to break the all-time high set in 2008.The Agriculture Department says exports in 2011 could top one hundred and twenty-six billion dollars. The largest buyer of agricultural products is expected to be Canada. But farm exports to China are predicted to come within five hundred million dollars of Canadian purchases. Secretary Vilsack says countries in Southeast Asia and the Middle East are also buying more from American farmers. Poor growing conditions overseas played an important part in higher prices for American crops in 2010.Charlotte Hebe brand is chief executive of the International Food and Agricultural Trade Policy Council in Washington. She said drought conditions had a big effect over the summer. She said,"There were horrible weather problems, not just in Russia but also in some of the other former Soviet Union countries." Wheat prices rose after Russia stopped wheat exports,although Russia later eased the ban ."Wheat used to be America's top crop. What's interesting,though,is that wheat production has actually become less over the past few years because corn has become the most popular crop,"said economist Charlotte Hebebrand. Corn is mostly fed to animals. But Miss Hebebrand said with the recent increase in wheat prices, American farmers might plant more wheat again. Corn and wheat are the two largest crops supported by the government. 
 Question: We know that compared to 2009,in 2010 American farmers----. 
 Options: (A) planted less corn (B) planted morn crops (C) planted morn wheat (D) earned more money 
 Asnwer: B

Solution: No
