SECTION A CONVERSATIONS
Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.
听力原文：M: Excuse me, are you waiting to buy concert tickets？
W: Yes, I am. So are all these people in front of me.
M: Have you been here long？
W: About 45 minutes. I've moved forward a total of about 3 feet in that time.
M: You're kidding!
W: Not at all. There was a couple up ahead of me who got so disgusted they finally gave up and left. They said they'd been waiting for more than an hour.
M: Does anyone know what's causing the delay？
W: If so, no one's letting us know. It could be that there aren't enough people selling tickets this afternoon. Or maybe their computer's down. I'm sure the concert hasn't been canceled.
M: I just hope they don't run out of tickets before I get up there.
W: That really would be annoying, wouldn't it？
M: I guess I should have come before lunch. Or has it been like this all day？
W: Apparently it has. In fact, before I came, I tried calling to charge my tickets over the phone, just to avoid this long wait, but they're not taking phone orders, or checks, or credit cards. It's cash or nothing. And you have to come in person.
M: Well, there're two more hours before the ticket office closes. Tickets to a good concert are worth waiting for. So I think I'll just make myself comfortable.
What is most likely true about the area in which this conversation is taking place？

A. It's crowded with people．
B. It's full of computers．
C. Lunch is being Served there．
D. Only few people in there．
