What is the opening concerned in the conversation?

M: So Patricia, [4] have you given any more thought to taking on an assistant in marketing?
W: Yes, and I’m still not sure about it.
M: Well, I guess we’d advertise the position internally as we always do.
W: But if we advertised the job internally, [5] we’d have the same old problems--not enough applicants and lots of internal political problems. Couldn’t we advertise the job outside the company for once?
M: Well, I suppose we could. But if we did, a lot of people wouldn’t be very happy about it.
W: But even if we promoted one of our own people, the other internal applicants wouldn’t be happy any- way. So what’s the difference? Why couldn’t we just advertise it in the national papers?
M: But it’s company policy. You know that. We always advertise internally first.
W: Yes, I know. But why can’t we try something different for a change? [5] If we took someone on from out- side the company we’d bring some new ideas into the department. It’s what we need.
M: Look. [6] why don’t we .just advertise it internally as we always do, right? That’ll keep everyone happy and then, after a couple of weeks, we can put an advert in the paper as well. What do you say?
W: Oh, all right. But I’m not going to do the interviews.
