M: Hello! I'm a senior student. Can you tell me whether this reference room is only for faculty members?
W: No, it's also open to the postgraduates, and undergraduates can come too if they've got professors' written permission.
Q: What does the woman tell the man about the reference room?
W: Let's talk about the preparations for the party.
M: Right. I think we really need to plan better and get things done in advance this time. Still remember what a mess it was at the last party?
Q: What do we know about the last party from the conversation?
