You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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: Yes
Why? 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.

New input: Article: PEOPLE who have had a painful experience may wish they could wipe the memory from their minds. Researchers at Johns Hopkins University, US, say that this may someday be possible. A drug remains far off, but researchers have laid a foundation with their discovery that proteins can be removed from the brain's fear center to cut memories forever. Previous research had already shown that a special behavior therapy could cut painful memories. But relapse was possible because the memory hadn't necessarily disappeared. By looking at that process, Richard Huganir and Roger Clem, two researchers from Johns Hopkins University, discovered a "window of vulnerability " when proteins are created. The proteins help signals travel within the brain as painful memories are made. Because the proteins are unstable, they can be easily removed with drugs or behavior therapy to cut memories. Researchers used mice to find the window, but think the process would be the same in humans. They used electric shocks to make the mice fear a certain sound. The sound triggered the creation of the proteins, called calcium-permeable AMPARS, which formed for a day or two in the fear centers of the mice's brains. The researchers are working on ways to reopen the window by recalling the painful memory and using drugs to remove the protein. They published their report online last month in Science Express. Their research has drawn interest and concern from experts in mental healthcare. Kate Farinholt, a mental health expert with the National Alliance on Mental Illness, Maryland, US, said many people suffering from a painful event might benefit from erasing a memory. "Erasing a memory and then everything bad built on that is an amazing idea, and I can see all sorts of potential ," she said. But there are a lot of unanswered questions, too. "Completely deleting a memory is a little scary. How do you remove a memory without removing a part of someone's life," Farinholt said. "And is it best to do that, considering that people grow and learn from their experiences?"
Question: What have researchers at Johns Hopkins University found recently?
