听力原文：M: Hello, Mrs. Kelly. I'd like to pick up my test, please. W: Sure. Whoso class are you in? M: Dr. Purcell's math class. W: And your name? M: My last name is Raleigh. R -A -L-E -I -G-H, W: That's fight. Jim Raleigh. Here it is. M: Thank you. And Terry Young's test too, please. W: Oh, I'm sorry. I can't let you take someone else's test. M: He's sick, and he can't come in to get it. He's my roommate. W: I understand. But the privacy act won't permit it. M: Really? Maybe you could tell him. W: Not even then. I can only give a test to the student whose name appears on it. I can't even give it to a family member. M: That's weird. W: I think so, too, frankly, but that's the law. M: Okay. I'll tell Terry, thanks anyway. W: You're welcome. Tell him I'll just keep his test here until he feels better and can come in for it himself. M: Okay. I'll do that. W: Have a nice day, Jim. M: You too, Mrs. Kelly. What do the speakers mainly discuss?
