In this task, you will be shown a conversation. You need to write a question with three choices for the conversation. Your question should be answerable based on the conversation and only have one correct answer. Note that you don't need to answer your question. "W" and "M" in the conversations stand for "woman" and "man".

But they are in the showroom. It's about half an hour's car ride. Are you free now? W: I will be free tomorrow afternoon. Suppose we make it, say, three o'clock tomorrow afternoon.
