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".

Q: W: Can you help me? M: What seems to be the trouble? W: There is something wrong with my bike. M: Oh. The brake seems to have become loose. That's dangerous. Without a good brake, you can't control your speed. Accidents are more likely to happen. You'd better have it repaired as soon as possible. W: Where can I find a repairman? M: There is one at the corner of the street near the post office. It is about 150 metres away. W: Will it take long to get it fixed? M: Just 15 minutes.
