The trained tour guides will show you a school's selling points.But the 1dest and prettiest buildings don't give you the entire picture of a college.Try to walk the extra mile and get the complete picture of the campus. 2.Read the Bulletin Boards When you visit the student center, academic buildings and residence hall, take a few minutes to read the bulletin boards.They provide an easy way to see what's happening on campus.The ads for lectures, clubs and plays can tell you what's going on outside the classrooms. 3.Eat in the Dining Hall You can get a good feel for student life by eating in the dining hall.Try to sit with students if you can.Do the students seem happy or stressed? Also, is the food good? Are there adequate healthy options? Many admission offices will give prospective students coupons for free meals in the dining halls. 4.Visit a Class in Your Major If you know what you want to study, a class visit makes a lot of sense.You'll get to observe other students in your field and see how involved they are  in classroom discussion.Try to stay after class for a few minutes and chat with the students to get their impressions of their professors and major.Be sure to call in advance to schedule a classroom visit--most colleges don't allow visitors to drop in on class unannounced. 5.Talk to Lots of Students Your campus tour guide has been trained to market the sch001.Try to talk to students who aren't getting paid to impress you.These important conversations can often provide you with information about co1lege life that isn't part of the admission script.Few university officials wi11 tell you if their students spend all weekend drinking or studying, but a group of random(,) students might.

Example Input: Article: A Russian legend has a story about the origins of cats. The cat's coat, it was said, was originally designed for the dog, but the dog became so impatient when coats were being handed out that he was told to wait at the back of the queue. The cat was given the fur instead of the dog. This, according to Russian folk storied, is the origin of why dogs dislike cats. A nameless cat with a taste for travel flew for three weeks between New York and Tel Aviv in 1984. It escaped from its owner's cat-box in the plane's luggage compartment on the first trip and all efforts to get it out with bowls of milk and food failed. After nearly 80,000 miles of flying the airline called in a vet who got it out. The Chinese attitude to the cat was not clear. Cats were welcome for their ability to kill mice and were considered suitable pets for women. On the other hand, they were suspected of bring bad luck into the home. In the days before the invention of the watch, it was said that they used their cats as clocks. The pupils of the cat's eyes were believed to gradually change shape with the position of the sun in the sky. At midday they were a narrow line and they gradually  became rounder until sunset. Britain's cleanest cat is undoubtedly Harvey, a five-month-old Persian who climbed into his owner's washing machine. He went through a ten-minute wash cycle before someone noticed him through the glass door, and pressed the "stop" button. Harvey was soon back to his usual self. Cats seem to be able to sense earthquakes. Josie, who lives in California, warned her family of a quake in 1971. She wore her owners. Mr. and Mrs. Miller, at 5:50am by jumping onto the bed and running around. When the Miller followed her out of the house, Josie ran off. The earthquake was only a small one, but the cat raised the alarm every time there was a quake after that.

Example Input: Article: Students and Technology in the Classroom I love my blackberry -- it's my little connection to the larger world that can go anywhere with me. I also love my laptop computer,as it holds all of my writing and thoughts. Despite this love of technology, I know that there are times when I need to move away from these devices and truly communicate with others. On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom, I have a rule -- no laptop, iPads, phones ,etc .When students were told my rule in advance of the class, some of them were not happy. Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There's a bit of truth to that. Some students assume that I am anti-technology. There's no truth in that at all. I love technology and try to keep up with it so I can relate to my students. The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly _ complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course the material and the class discussion. I've been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course material beyond the classroom. I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I'm sticking to my plan. A few hours of technology-free dialogue is just too sweet to give up. 
 Question: Some of the students in the history class were unhappy with   _  . 
 Options: (A) the course material (B) others' misuse of technology (C) discussion topics (D) the author's class regulations
Example Output:
D
