Read the sentence from Last Lecture by Randy Pausch.All right, so what we’re not talking about today, we are not talking about cancer, because I spent a lot of time talking about that and I’m really not interested.

Pausch says he has already spent a lot of time talking about cancer and is not interested in discussing it today. This suggests he has chosen not to focus on his cancer in this part of the lecture. He does not say that speeches about cancer are generally uninteresting, so choice D goes too far.
