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.

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: Gauri Nanda sees a wearable computer as a handbag -- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded in it. It looks, feels and weighs like your typical leather purse. That's where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf. Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle. As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse. Here's how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go. _ Indeed, more people will want to cross that bridge in the coming years -- making for a booming market for wearable computers that don't like something out of science fiction.
Question: Which of the following describes a wearable computer?
Options: (A) It can be washed in a washing machine. (B) It is much heavier than a leather purse. (C) It can download songs from the Internet. (D) It is made of clothes conducting electricity.

Output: A

Input: Consider Input: Article: Technology helps people do everything from planning to meet for a movie to keeping in touch with a friend who lives in a different country. When planning to get together with friends, Julian said , " If I want to go and see a movie with a few friends, I usually send them text messages. By telephone, you have to call every single friend one by one. But text messaging allows you to send the same message to as many people as you'd like, which saves a lot of time." Email, IM, and other low-cost methods of communication also help people keep long-distance friendships in ways they couldn't have even a few years ago. Mike told us, "I had this friend when I was 8 or 9 , and then she moved away to the country. We promised to stay friends and to send letters, and at the start we did. Then the letters got fewer and fewer and we at last stopped writing to each other. I think if we had had email, we would still be in touch." James found out about cost the hard way. He said, " I called my friend in New Zealand, which is halfway around the world, and it cost me over $200! So now I just stay up late to see if I can catch him on MSN or I write an email." Email, IM, and other low-cost ways of keeping in touch also allow people to develop brief acquaintances into long- lasting friendships. Andrea told us, " I met this really cool girl. We've been in touch over half a year and it's nice to talk to her."
Question: How does Julian usually get in touch with a group of friends?
Options: (A) By emailing them. (B) By chatting with them on MSN. (C) By sending them text messages. (D) By giving them a phone call.
