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.
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
Example solution: Yes
Example explanation: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. Hence, B is the correct answer and output is Yes.

Problem: Article: As shocking as the idea of baby birds growing up in a cigarette-filled home sounds, a new study suggests that some birds may benefit from putting the stuff from cigarette butts into their nests. The nicotine remaining in smoked filters may serve as a natural insecticide , driving harmful insects away from the nests and the baby birds living within. Tobacco plants produce nicotine because it defends against insects that would otherwise eat the plants. The butts are undoubtedly smelly. But birds are actually quite fond of smelly chemicals, such as those found in aromatic plants. Some nest-building species regularly fill their nests with fresh aromatics, possibly because the chemicals are good for the immune system or the development of the chicks. Alternatively, the plant chemicals might act as insecticides. In the study, researchers at the Autonomous University of Tlaxcala in Mexico set up heat traps, which attract harmful insects, in 55 nests around Mexico City. Some traps were lined with the stuff in smoked cigarette filters. The others were lined with the stuff from unsmoked cigarette filters, which did not contain nicotine and other smoking by-products. Whether the nest held eggs, chicks or nothing, the unsmoked cigarette traps collected more harmful insects, suggesting that it is the chemicals that drove harmful insects away. In a second experiment, the researchers collected 28 house sparrow nests and 29 house finch nests from Mexico City immediately after the chicks flew out for food. They found that the more smoked filter stuff filled a nest, the fewer harmful insects it had. The missing piece of the puzzle is whether the reduced number of harmful insects in the nests actually provided any benefit to the chicks. It is also unclear if nicotine or another chemical found in cigarettes may have turned the harmful insects out of the nests. If the results hold, then this study is an example of wildlife adaptation to urbanization - or at least evidence that birds are smart and can still follow their noses in urban environments.
Question: What may be the function of nicotine in cigarette butts for birds?
Options: (A) To provide building materials for bird nests. (B) To drive harmful insects away from bird nests. (C) To protect the plants from being eaten by insects. (D) To attract baby birds to stay in the nests.
Asnwer: B
Solution: Yes
