What is the relationship between the two speakers?

Man: Hi, Lynn. (4[C])I saw you at registration yesterday. I sailed right through. But you were standing in a line.
Woman: Yeah. I waited for an hour to sign up for a distance learning course.
M: Distance learning? Never heard of it.
W: Well, its new this semester. (5[D])It’s only open to psychology majors. But I bet it’ll catch on elsewhere, Yesterday over a hundred students signed up.
M: Well, what is it?
W: It’s an experimental course. I registered for Child Psychology. All I got to do is watching a twelve-week series of televised lessons. The department shows them several different times a day and in several different locations.
M: Don’t you ever have to meet with your professor?
W: Yeah. After each part of the series, I have to talk to her and the other students on the phone, you know, about our ideas. (6[B])Then we’ll meet on campus three times for reviews and exams,
M: It sounds pretty non-traditional to me. But I guess it makes sense considering how many students have jobs. It must really help with their schedules. Not to mention how it’ll cut down on traffic.
W: You know, last year my department did a survey and they found out that 80% of all psychology majors Were employed. That’s why they came up with the program. Look, I’ll be working three days a week next semester and I will either cut back on my classes or try this out.
M: (7[B])The only thing is, doesn’t it seem impersonal though? I mean, I miss having class discussions and hearing what other people think.
W: Well, I guess that’s why phone contacts are important. Any way it’s an experiment. Maybe. But FII be curious to see how it works out.
