A、2:30 pm. B、3:30 pm. C、4:30 下午 D、5:00 下午 B数字细节题。四个选项都是表示时间的词，可推断问题是关于事件发生的时间。男士提到他们的传真机要到2：30才能修好，所以要求女士在 3：30把资料传真给他，故选项B正确。

W: Hello, Ultimate Computers. May I help you?
M: Yes, this is Jack Kordell from Hunter’s Office Supplies. May I speak to Elaine Strong, please?
W: [19] I’m sorry, but she’s not in right now.
M: Okay, do you know when she’ll be back?
W: Uh, yes, she should be here later on this afternoon maybe about 4:30. May I take a message?
M: Yes. [20] Ms. Strong sent me a brochure detailing your newest line of laptop computers with a description of other software products, but there wasn’t any information about after-sales service.
W: Oh, I’m sorry. Would you like me to fax that to you?
M: Yes, but our fax is being repaired at the moment, and it won’t be working until around 2:30. Hum... [21]  could you try sending that information around 3:30? That should give me time to look over the material be- fore I call Ms. Strong, say, around 5:00.
W: Sure. Could I have your name, telephone number, and fax number, please?
M: Yes. Jack Kordell and [22] the phone number is 560-1287. And the fax number is 560-1288.
W: Okay. Jack Kordell. Is your name spelled C-o-r-d-e-l?
M: No. It’s Kordell with a "K" and two "1". K-o-r-d--e-l-l.
W: All right Mr. Kordell. [22] And your phone number is 560-1287, and the fax number is 560-1288. Is that correct?
M: Yes, it is.
W: All right. I’ll be sure to send you the fax this afternoon.
M: Okay, bye.
