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. 
 Question: Researchers did experiments on kids in order to find out _ . 
 Options: (A) how they really feel when they are learning (B) whether mood affects their learning ability (C) what methods are easy for kids to learn (D) the relationship between sadness and happiness 
 Answer: B
Solution is here: Yes

Now, solve this: Article: When people talk about Golden Age in Leadville, Horace Austin Warner Tabor and his second wife, Elizabeth McCourt must be included. Their story is becoming one of the legends of the Old West. H.A.W.Tabor was a school teacher in Vermont. With his first wife and two children he left Vermont in 1855 to settle in Kansas. Perhaps he was attracted by rumors of fortunes to be made in Colorado mines. A few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. "Great deposits of lead are sure to be found here."he said. As it turned out, it was silver, not lead, that was to make Leadville's fortune and wealth. Tabor knew little about mining himself, so he opened a general store selling everything from boots to salt, flour, and tobacco. He often "grubstook" miners, in other words, to supply them with food and supplies, or"grub", while they looked for more. In return he would get a share in the mine if one was discovered. He did this for several years,but nobody he helped ever found anything of value. Finally one day in the year 1878, so the story goes, two miners came               in               and asked for "grub".Tabor had decided to quit supplying it because he had lost too much money that way. They were persistent, however, and Tabor was too busy to argue with them, " Oh help yourself. One more time won't make any difference," He said and went on selling shoes and hats to other customers. The two miners took $17 worth of supplies, in return for which they gave Tabor a one-third interest in their findings. They picked a barren place on the mountain side and began to dig. After nine days they struck a rich amount of silver. Tabor bought the shares of the other two men, and so the mine belonged to him alone. This mine, known as the "Pittsburgh Mine,"made $300 000 for Tabor in return for his $17 investment.                Later Tabor bought the Matchless Mine on another barren hillside just outside the town for $117 000. This turned out to be even more successful than the Pittsburgh, earning $35 000 worth of silver per day at one time. Leadville grew. Tabor became its first mayor. 
 Question: According to the passage, why was Tabor able to achieve great success in Leadville? 
 Options: (A) His wise decisions helped him achieve goals. (B) He knew miners there were poor. (C) He succeeded quite by accident. (D) His second wife helped him a lot. 
 Asnwer: B
Solution:
No
