【正确答案】 C
【答案解析】[听力原文]
   W: Ken, don't forget there's a management training class starting today at 1:30 p.m. in the large conference room. The general manager will be there to welcome everyone.
   M: I completely forgot about that. And I already arranged a presentation for a group of buyers at noon. Do you think it would be a problem if I missed the first session?
   W: If I were you, I would try to reschedule the meeting. The training is compulsory and we have to personally reimburse the company for missed sessions.
   M: That's a good point. I'll cancel the appointment, then. I don't want to be the only one absent.
