A、How to persuade others to do car wash. B、How to organize the Thanksgiving party. C、How to get the raising-money message out. D

M: Come on, Judy, how are we going to convince everybody that my car wash idea is the best way to raise money for the Thanksgiving party at the student center?
W: It won’t be easy.
M: Thanks a lot!
W: Oh, I’m just kidding. Actually, I think once we show how much money it could bring in, we’ll be sure to convince everyone on campus to pitch in.
M: Well... how are we going to get the message out?
W: One thing I was thinking of is to hang up posters on the bulletin boards.
M: But that’s not going to attract much attention. We need to do something interesting.
W: Let me finish: I know someone who works at the campus print shop. Last week he said he could get hold of materials to make a big banner. That’ll attract the attention of a lot of students if we can hang it in front of the student center.
M: Nice work!
W: I’ve also arranged to have an article published in the school paper next Wednesday. That way you can get the message out to the entire campus.
M: Uh-oh, that means I had better come up with an article pretty quickly. How about if I write it up and I’ll let you be the first to read it? How about after English class tomorrow?
W: Sounds like a plan. I’ll see you then.
M: You’re the greatest. I don’t think I would have known what to do without your help.
