Question 7 - 9 refer to following conversation:
M-Cn: Jackie, some of our hotel guests would like to see the symphony orchestra perform tomorrow night. I've called the box office a couple of times to book tickets for them, but I just get a recording.
W-Am: Well, I've got a brochure about another classical music performance happening tomorrow night at a different venue. Why don't you ask our guests if they'd be interested in seeing that show instead?
M-Cn: Great! I'll stop by your office when I get back from lunch. I'll get the details then.
