M: Hello. This is Tom Davis. I have an appointment with Mrs. Jones for nine o’clock this morning, but I’m afraid I’ll have to be about fifteen minutes late.
W: That’s alright, Mr. Davis. She doesn’t have another appointment scheduled until ten o’clock.
Q: When will Mr. Davis most probably meet with Mrs. Jones?

W: It’s so hot today I can’t work. I wish there were a fan in the library.
M: So do I. I’ll fall asleep if I don’t get out of this stuffy room soon.
Q: What are these people complaining about?
