Teacher: In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Article: Homework can put you in a bad mood , 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
Solution: B
Reason: It is clearly mentioned in the article that to the check effect of mood on children is the main purpose of the experiment. So, B is the correct answer.

Now, solve this instance: Article: In the Internet age, speed reading is a necessary and important skill. We skim over articles and e-mails to try to get key words and the main idea of the text. With so much information through our electronic devices , it would be impossible to get through everything if we read word by word, line by line. However, a new trend calls on people to enjoy reading slowly. A recent story from The Wall Street Journal reported on a book club in Wellington, New Zealand, where members meet in a cafe and turn off their smartphones. They sit back in comfortable chairs and read in silence for an hour. Unlike typical book clubs, the point of the slow reading club isn't to exchange ideas about certain books, but to get away from electronic devices and read in a quiet, relaxed environment. According to the story, the Wellington book club is just one example of a movement started by book lovers who miss the traditional way of reading. Traditional readers, like Maura Kelly, say a regular reading habit sharpens the mind, improves concentration, reduces stress levels and deepens the ability to understand others. Some of these benefits have been backed up by science. For example, a study of 300 elderly people published by the journal Neurology last year showed that adults who take part in activities that use their brain, such as reading, suffer less memory loss as they get older. Another study published last year in Science showed that reading novels helps people understand others' mental states and beliefs -- a key skill in building relationships. Yet technology has made us less careful readers. Computer and phone screens have changed our reading patterns from the top-to-bottom, left-to-right reading order we traditionally used, to a wild skimming pattern as we hunt for important words and information. Reading text online that has many links to other web pages also leads to weaker comprehension than reading plain text. The Internet may have made us stupider, says British journalist Patrick Kingsley, only half joking. Because of the Internet, he says we have become very good at collecting a wide range of factual tidbits , but we are also gradually forgetting how to sit back, think and connect all these facts with each other.
