A、To go shopping. B、To do research for her story. C、To meet with her professor. D、To take a break from her work. B[听力原文] Why is

M: I am so relieved, I just finished the story I was working on for our Creative writing course.
W: I haven’t quite finished mine yet. I had trouble getting past the beginning.
M: How come?
W: Well, I was really happy to be writing a detective story. But after the first few pages, I sort of froze up mentally. I just couldn’t write any more.
M: The same thing happened to me. I thought it meant I lack imagination.
W: Well, Professor Wilson said it’s pretty common for writers to get stuck like that.
M: You went to talk to her about it?
W: Actually, I went to ask for more time to finish the assignment. But instead she gave me some advice about how to keep from getting stalled writing like that. She said that the first thing I should do is just write anything that comes into my head even if it doesn’t make any sense, sort of warm up exercise.
M: That is interesting. When I got stuck, I shift to something else, you know, do some work for one of my other courses.
W: Well, her methods seem to have worked for me. I’ve written most of the story, and I should be able to hand it in on time. But first I need go to the jewelry store.
M: You are going shopping? Can’t you wait until you finish your story?
W: I am going there for my story. My detective solves a jewelry store robbery, so I want to take a look at how the jewelry cases are arranged, where the security cameras are located, that sort of thing.
