What is the woman’s problem?

W: Hello! Who’s speaking?
M: Hello, is Jane available? Can I speak to her?
W: Jane’s speaking. Who’s calling please?
M: Hi, Jane, (6) this is Mike calling from Dr. Pasteur’s Institute, I’m calling to confirm your appointment for tomorrow morning at 9 a. m. with Dr. Pasteur.
W: Oh, I almost forgot. Thank you so much for calling to remind me of that. Actually, I do need to change the time of my appointment. (4) I have a scheduling conflict. And I can’t make it that early.
M: What about I put you in at a later spot, would that work out?
W: It has to be after lunch. Do you have anything available about 2 o’clock p. m. ?
M: Sorry madam, the only opening we have after lunch is 1:15 , but I might be able to work you in after 3. Would that be a better time?
W: That’s alright. I think I should be able to make it at 1: 15. Can you put me down for that time slot?
M: No problem. I have your appointment (5) (6) changed from tomorrow morning to tomorrow afternoon at 1: 15. All right?
W: Wonderful. Thanks very much.
