What is the focus of the woman’s presentation?

F: Hi, Professor Gordon. I wanted to talk about the wildlife presentation on May 19th.
M: Have you decided how to organize it?
F: Yes, professor. At first, I was going to focus on the cat family, but then I decided to talk about nocturnal animals instead.
M: Yes, good idea. And how is your plan going?
F: It’s going well. I think I have enough material for 20 minutes. The advantage is that there’re so many visual aids I can use. I’ve found lots on the Internet, which I think will be really interesting for people. The problem is that it’s been hard to narrow down. How do you think I could limit it to 20 minutes?
M: It’s a broad subject. There’re a few ways you could do it. But I’d recommend just looking at a representative sample, just four or five.
F: Yes, and maybe I could choose one animal from each continent, or a land creature, a marine creature and a winged animal.
M: I like the idea of separating it by different types of animals. Also, think how you’re going to interest the audience.
F: Well, I’m going to have a picture for each animal so I can talk through the picture.
M: That’s nice, but don’t limit yourself to pictures. If you can find any video clips of the animals, use them. Showing brief video clips can keep your audience interested.
F: I’ll look on the Internet tonight.
M: And think of questions to ask your audience. People like to be involved.
F: Yes, that’s a great idea. Anyway, professor, I’ll have got everything ready by May 10th. Can I show you a small section at that time?
