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.

Example Input: Article: You know you have to read "between the lines" to get the most out of anything. I want to persuade you to do something equally important in the course of your reading. You have to "mark between the lines". By marking you can make the most efficient kind of reading. There are two ways in which one can own a book. The first is the property right you have by paying for it, just as you pay for clothes and furniture. While full ownership comes only when you have made it a part of yourself and the best way to make yourself a part of it is by writing marks on it. Why is marking up a book _ to reading? First, it keeps you awake. Second, active reading is thinking, and thinking tends to express itself in words. Finally, marking helps you remember the thoughts you had, or the thoughts the author expressed. Reading a book should be like making a conversation, a conversation between you and the author. Although he knows more about the subject than you do, don't let anybody tell you that a reader is only on the receiving end. Understanding is a two-way operation. Reading doesn't mean being a passive empty receiver, the reader has to question himself and question the author. And marking a book can show his own judgment on author's opinion: agreement or difference.
Question: The author thinks "marking between the lines" is _ .
Options: (A) the most important of all (B) more important than "reading between the lines" (C) as important as "reading between the lines" (D) not so important as "reading between the lines"
Example Output: C

Example Input: Article: Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers. Of course sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, they inquire into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however. the new rules came too late to protect the people who died or who became seriously ill. Today many governments have special departments which protect customers and workers.In the U.S, for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work. and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness. but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.
Question: The main topic of the passage is _ .
Options: (A) conditions in the work place (B) the freedom of industries in the past (C) changes in industrial production (D) the safety and health of workers and customers
Example Output: D

Example Input: Article: Most people say "yes" much more readily than "no". A friend is moving house this weekend and would like some help, and you agree. But, what you really wanted was a couple of quiet days relaxing at home. Or a roommate spends the entire weekends playing video games and wants to borrow your homework for "reference". You say "yes". Many people say "yes" to these kinds of requests. They tend not to consider their own interests and feelings, and are often angry with themselves afterwards . Saying "no" requires courage and considerable practice, in fact, according to psychologists. "Everyone wants to be liked," says Gabriele Steinki, a German psychologist. "Saying 'no' risks losing the affection of the person asking the favor or even a job." The result is that many people say "yes" just for keeping the peace. But experts say this is regrettable. Anyone should have the right to say "no". In fact, rejecting a request can even help to strengthen a relationship because it expresses a true feeling. But, for people used to agreeing to every request, changing can be a long and uncomfortable learning process. Most people believe that "If I say 'no', I'll lose the affection of the person. But the affection is important to me." This way of thinking can be replaced by this: "If he only likes me because I always do what suits him , the price of his affection is too high in the long term." Steinki says the key is talking to the other person to find a mutual solution. "One needs to present the situation from one's own point of view, and to suggest how the situation can be dealt with to the advantage of both parties. The other person must have the feeling that his interests are being considered." When the refusal is not accepted, Steinki advises us to give the reasons calmly again until the person gets the message .
Question: Most people say "yes" much more readily than "no" because _ .
