Question 1 - 3 refer to following conversation:

W-Am: Excuse me, sir, but I think you're in my seat, 14-A?

M-Au: Let me take a look at my ticket... hmm, no, it seems I'm in the right place. My ticket says 14-A as well.

W-Am: Well... this is train car five. Are you sure you're in the right car?

M-Au: Oh, pardon me! I'm 14-A in car six. I've put my bags on the overhead rack, so just give me a moment to get my things together.

1. What are the speakers discussing?

W-Am: Thanks for this follow-up visit, Mr. Kessler. Your team did a nice job installing the parking area for my office building. It's smooth and even. However, as you can see, behind the building, the work was never finished. Only a few of the white stripes that mark the individual parking spots have been painted.

M-Cn: Hmm... Yes, I see. My team was supposed to paint that final section on Tuesday, but all the rain last week put us behind schedule.

W-Am: I hope you'll be able to take care of this soon.

M-Cn: Sure, that won't be a problem. I'll put you on the schedule right away, and we'll come by first thing tomorrow and get this all done for you.

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.
