Yes. They can specify which poem in Birthday Letters (I think it's poetry, sorry if I'm wrong), which episode of Frontline, and which chapter of The Justice Game (and same goes for other options in Module C). You're supposed to study all of them so they're perfectly in their rights to ask you to talk about one of them. If you're really stuck with the part they ask you to talk about, say what you know about it, then add another part (for example: it happened to me, and I talked about the chapter on Diana (compulsory- but I said very little because I hadn't really studied it enough), as well as Trials of Oz and Malcolm X (I did the Justice Game)). Good luck!
