M: Have you read the whole book since noon today? ,F: Oh, I haven't read it straight through the way you'd read a novel. A few chapters were on the topic that interested me. So I just read those.
(A) M: Just a minute! I do not quite follow what you are saying, would you mind repeating that? (B) M: Why have you been reading this book since the day before yesterday when you only read the front chapters? (C) M: Although you have been reading this book since yesterday, you only read the chapters you are interested in, right? (D) M: Haha, you only read the chapters you are interested in.
