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: For medical students, real experience begins not in a classroom but at a teaching hospital. These doctors in training are guided. But sometimes accidents happen and the students get injured. For example, they might stick themselves with a needle while treating patients. Such needle sticks are common. But a recent study found that medical students often fail to report them. Failing to report an injury like this can be dangerous if a patient, or a medical worker, has an infectious disease. Researchers at Johns Hopkins University in Baltimore, Maryland, did the study, which involved a survey answered by almost 700 surgeons in training in the United States. Almost 60% said they had suffered needle stick injuries when they were in medical school. Many said they were stuck more than once. Yet nearly half of those whose most recent incident happened in school did not report it to a health office. If they had, they would have been tested to see if they needed treatment to prevent an infection like HIV or hepatitis. Most known cases of HIV or hepatitis are reported, but other possible infections often are not. Martin Makary, the lead author of the study, says medical students who are stuck put themselves and others in danger from infectious diseases. Doctor Makary said, "A needle that goes through the skin needs to be as sharp as possible." Doctors in training may have to do hundreds of stitches   in some cases to close the skin after an operation. Doctor Makary said, "I support using _ tip needles which are considered safer. This needle is still sharp enough to go through body tissue, but it does have a blunt tip, so that if it accidentally goes into my finger, it's much less likely to hurt me." How common are needle sticks among health care workers? An estimated 600,000 to 800,000 of these and similar injuries are reported each year in the United States. But Doctor Makary says the real number may be much higher. The study advises doctors to protect their hands by wearing two sets of gloves. It also urges hospitals to establish a special telephone number for medical workers and students to call if they are injured. The idea is for hospitals to send a clear message that there is no reason not to report this kind of accident. 
 Question: It is dangerous for medical students not to report needle stick injuries because   _  . 
 Options: (A) they don't know how to treat themselves. (B) they may meet more needle sticks (C) it may cause some diseases (D) it may make patients sad. 
 Asnwer: B
Solution:
No
