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.
One example is below.
Q: 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
A: B
Rationale: 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.
Q: Article: Drunken driving--sometimes called America's socially accepted form of murder--has become a national epidemic . Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past ten years. A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or several glasses of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American manly image and judges were serious in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant. Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18-20-year-old drivers more than doubled, so the state recently upped it back to 21. Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop "responsible attitudes" about drinking and teach them to resist peer pressure to drink. Though new laws have led to increased arrests and tests and, in many areas already, to a marked decline in accidents, some states are also punishing bars for serving customers too many drinks. A bar in Massachusetts was fined for serving six or more double brandies to a customer who "obviously drunk" and later drove off the road, killing a nine-year-old boy. As the accidents continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years of national prohibition of alcohol that began in 1919, what President Hoover called the "noble experiment". They forgot that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.
Question: In America, public opinion about drunken driving has changed because _ .
Options: (A) judges are no longer serious (B) new laws are introduced in some states (C) the problem has attracted public attention (D) drivers do not appreciate their manly image
A:
C
