Which THREE things does Cesar recommend bringing?A binocularsB cameraC pen

R: And what’s happening on the second day?
C: Um... well, we’re coming back to town and going to the Water Treatment Plant to see how they purify the water for drinking.
R: Oh, that should actually be quite interesting. I’ll bring my camera.
C: Yes, that’s a good idea because we’re supposed to include original photos for the final piece of work at the end of the course. And make sure you
bring a notebook and pen or pencil.
R: OK I’ll do that.
C: You’ll probably need some good walking shoes and spare clothes, too. And I would recommend that you bring a waterproof coat of some sort because the chances of it raining are pretty good next week. And a hat, perhaps?
R: Sorry, no. I draw the line at a hat!
C: Fair enough. And by the way, do you have a mobile phone?
R: I do actually.
C: Well, bring that along because that way we can keep in touch more easily.
R: Provided that mobiles work up there, of course!
C: That’s a point.
R: Do I need a map?
C: No, I wouldn’t bother. We won’t need to do any map reading.
R: OK, then. See you on Monday, and thanks very much for letting me know.
