M: Miss Smith, I told Dr. Brown that I would call him in the Houston office at ten o’clock their time. Please find out the time difference for me so that I’ll know when to place the call.
W: It’s two hours earlier in Houston, Sir. I know without looking it up because my sister lives there.
Q: When should the man place his call to Houston?

M: I agreed with your proposal at the meeting this morning, it was a good one.
W: You should back me up then, when I need it.
Q: What does the woman mean?
