M: Some of these books aren't so old, though... See? This mystery was published only six years ago. It cost seventy-five cents. You can't beat that. W: Hey! Look at this! M: What? Are you getting interested in nineteenth century poetry all of a sudden? W: No. Look at the inscription! Someone gave this book as a present, and wrote a note on the inside of the front cover. It's dated 1893. Maybe it's worth something. M: Everything on that shelf is worth fifty cents. W: But if this is a signature of someone who is well known, it might bring a lot more. I hear William Shakespeare's signature is worth about a million dollars., Question: Where does this conversation take place? (A) In a library. (B) In a school. (C) In a bookstore.
