Input: Consider Input: Article: The challenge to drink to the limits of one's endurance has become a celebrated part of college life. In one of the most extensive reports on college drinking thus far, a 1997 Harvard School of Public Health study found that 43 percent of college students admitted binge drinking in the preceding two weeks (Defined as four drinks in a sitting for a woman and five of a man, a drinking binge is when one drinks enough to risk health and well - being ) Experts estimate that excessive drinking is involved in thousands of student deaths a year. And the Harvard researchers found that there has been a dramatic change in why students drink. 39 percent drank "to get drunk" in 1993, but 52 percent had the same objective in 1997. "What has changed is the across - the - board acceptability of intoxication ," says Felix Savino at UW - Madison. Many college students today see not just drinking but being drunk as their primary way of socializing. The reasons for the shift are complex and not fully understood. But researchers guess that it may have something to do with today's instant - satisfaction life - style--and young people tend to take into the extreme. While binge drinking isn't always deadly, it does have other, wide - ranging effects. Academics is one area where it takes a heavy _ (something paid, lost or suffered). Perhaps because alcohol increases aggression and affects judgement, it is also related to 25 percent of violent crimes and roughly 60 percent of vandalism on campus. Facing the many potential dangers, college campuses are searching for ways to reduce binge drinking.
Question: Why has "binge drinking" caused widespread concern?
Options: (A) Because it is directly responsible for the academic problem on campus. (B) Because it has claimed many young lives every year. (C) Because it has had harmful effects on the students' health and well - being. (D) Because it is in close connection with school violence.

Output: C

Input: Consider Input: Article: There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. and some do one simple job. When an automatic washing machine is switched on, water pours in. The machine waits until the water is warm enough for washing clothes. It does this by "feedback" . Information about what is happening is feedback into the robot to tell what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us. So robots are like human beings in two ways. They work and they have feedback. In some ways robots are better than human beings. They work quickly and do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. First their electronic brain must be shown how the job is done. A person moves the robot's "arms" and "hands" through each part of the job. The most intelligent robots can move and see. Their eyes are cameras. Their fingers can feel shapes and sizes of the objects. These robots have computer brains linked to their eyes and fingers, which control their actions. The expensive robots are used in scientific research. They do such job as handling radioactive materials.
Question: In this passage the author tells us that _ .
Options: (A) robots are very popular (B) there are various kinds of robots (C) we see robots only at certain times (D) robots can be easily controlled

Output: A
