Question 19 - 21 refer to following conversation:
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.
19. What problem does the woman mention?
