Ex Input:
F: Hey, Mike, you're back. How was your summer camping? ,M: Life in the great outdoors isn't exactly what I expected. ,F: What did you do everyday? ,M: First, everyone had to get up at 5:30 AM. Next, we had to make our beds before our camp adviser came to inspect the place. Then we had breakfast around 6:30 AM. After that, we had some free time, so I'd go down to the nearby stream to fish for a couple of hours. But yesterday, the only thing I caught was an old shoe and a tree branch. Then I slipped and fell in the stream and lost my fishing pole. In the afternoon, there were different activities we could choose from like swimming, horseback riding, and hiking.
(A) F: It's not rare losing your fishing pole. It also occurred to me once. (B) F: Are you alright? It must be very hurt to be hit by a tree branch. (C) F: Do you mean that you lost your fishing pole the day before yesterday? (D) F: I’m sorry, I don’t understand. Could you say it again?
