M: Hello.
W: Hello.(19)I saw your advertisement in the paper and I’m calling to ask about renting an apartment.
M: Certainly. What kind of apartment do you have in mind?
W: Well, I don’t know exactly...I mean,(20)it depends on price, to some extent.
M: OK, now we have properties across the whole range. The average is probably $ 120 per week.
W: Oh, it’s a little expensive than I thought.
M: They start at $ 90. That’s the lowest we have usually. And they go up to $ 180.
W: I could manage the lowest figure.
M: An important question is how long you’re planning to rent. We don’t do short lets.
W: I’d want an apartment for nine months, perhaps longer.
M: That would be fine. Our contracts are for a standard six months, and that can be extended. What else would you like to know?
W: I wonder what’s included in the rent?
M: That depends, to a certain extent, although some things are standard in all flats.(21)For example, every apartment has a closed circuit TV for you to use.
W: Good. What about kitchen equipment? Do you offer tableware? You know plates, knives and forks, things like that.
M: No, only the microwave ovens, fridges I am afraid.
W: OK. What about the utilities? Are they all included in the rental?
M: I don’t think so. You see, you have to pay for the heating bills. But the gas bill is part of the rent, so you don’t have to pay for that.
W: Right. I’d made a note of that.
M: Are you looking to move in soon?
W: I hope so. What about the viewing arrangement?
M: Alright, can you come to our office on Thursday?
W: OK. See you then.
19. What are the two speakers talking about?
20. What will affect the woman renting an apartment to some extent?
21. What is standard in all flats?
