Question 13 - 15 refer to following conversation:
M-Cn: Hi, Siba. Do you need help taking those files up to our office? It looks like you have your hands full
W-Br: If you don't mind, that'd be great. The elevator is still out of order, so we'll have to use the stairs
M-Cn: But that broke last week - the maintenance crew should have repaired that by now
W-Br: Well, apparently a piece of hardware had to be custom made
M-Cn: Ah, I see. Well, at least our office is only on the second floor, so we don't have to climb too many stairs
W-Br: That's true. Thanks again for carrying some of these files - it would have taken two trips to get them all without your help
13. What does the man offer to do?
