Question 15. Tom, would you please watch my suitcase for a minute? I need to go make a quick phone call. Yeah, sure. Take your time. Our train doesn't leave for another 20 minutes. What does the man mean? Question 16. Frankly, Mary is not what I'd called easy-going. I see. People in our neighborhood find it hard to believe she's my twin sister. What does the woman imply? Question 17. How soon do you think this can be cleaned? We have same day service, sir. You can pick up your suit after five o'clock. Where does the conversation most probably take place? Question 18. I really enjoy that piece you just played on the piano. I bet you get a lot of requests for it. You said it. People just can't get enough of it. What do we learn from the conversation?
