Question 4 - 6 refer to following conversation:

W-Br: Hi, Mr. Lin, I'm calling from Central Dentistry. You have an appointment with Dr. Sumner on June eighth at two P.M. 361 was wondering if we'd be able to move your appointment to three o'clock.

M-Cn: Well, I have a sales call scheduled that morning, but I think three o'clock would be all right.

W-Br: Wonderful, we really appreciate it. Most of our staff will be attending a dental workshop earlier in the day, and they are concerned about getting back in time.

M-Cn: No problem at all. I'll mark down that change in my calendar right now.
