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
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.

Now, solve this: Article: Babies understand what their mothers say, even when they speak a language their children have never heard before, scientists claim. The researchers found that one-year-olds reacted in exactly same way to their mothers' voices regardless of whether they were speaking English or Greek, showing what mothers have long known - that babies pick up on tone of voice rather than the words themselves. The researchers, from Cardiff University's School of Psychology, observed babies as they watched their mothers perform actions with toys using the English words "whoops" and "there". The scientists studied reactions from one-year-old babies to their mums' voices even when they were speaking both English and Greek, and keeping the same tone of voice. The academics found that babies reproduced the same reactions regardless of whether they knew the language. Study leader Dr Merideth Gattis of Cardiff University's School of Psychology says, "What this work showed was that children could have access to understanding simply through tone of voice. We did 'whoops' and 'there' in two languages and got exactly the same results." The research, published in the journal Cognitive Development, was conducted on 84 babies aged between 14 and 18 months, over the course of a year, with none of the babies having any previous exposure to Greek. Dr Gattis says that children respond to tone clues in their parents' voices from an early age. She says, "Tone of voice is a really useful signal of what someone is thinking. We never have direct access to other people's minds, except the signals in language that they give out." She says the study shows that it is less important what parents say than how they say it. Dr Gattis adds, "A child may ask if you like his / her drawing, for example. You might say yes, but if you don't sound enthusiastic, the meaning may not get across." Before children begin to speak, parents should use exaggerated tone when speaking to them.
