听力原文：W: Hi, Sam, I hate to bother you but I wonder if I could have a word with you? M: Sounds so serious. What's up? W: Well, the landlord just informed me that he's going to increase our rent by two hundred. I'm wondering how you feel about it. M: How do I feel about it? No way! In the rental agreement, it says he will have to give us a notice three months in advance if he wants to increase the rent. W: Yeah, that's right! It's gotta be three months later. Well, I think he realizes his rental fee is below the market rate and he must be feeling a bit ripped off when he could be charging a couple hundred extra. What do you think, Sam? Should we agree to the raise or find somewhere else? M: Good question. I'm not sure either. The location we're at now is quite convenient, close to the grocery and near the subway. It'll be hard to find another location like this one. W: I wonder whether he'll allow room for negotiation, perhaps a hundred dollars instead of two. Maybe he might be more willing to give a bit if we speak to him right away. M: Well, he seems to be a nice guy to talk to. But what if he refuses? Would you go for two then? W: Well, I guess I would, since it'll be hard to find such a convenient location. Besides, it's close to my school and I can sleep a little later in the mornings. M: Ha! I figured that's what you'd be concerned about. Well, I have to give it some serious thought. I'm not sure I can afford to cough up an extra hundred a month just to make sure i can sleep in an extra 15 minutes. W: Didn't you get your loan recently? That'll cover what you need. Besides, if you could just stop spending so much on cafeteria snacks you'd have lots of money to spare. M: Yeah, but I'm thinking of getting a new laptop. W: Well, I tell you, there aren't a lot of apartments that are cheaper, even with this new increase. M: I know, so when does he want us to come back on this? W: He told me to let him know this weekend. M: Sure, by then I should be able to make up my mind. 23．What is the main Problem that the speakers have? 24.What are the two choices that they face? 25.What is the advantage of staying in the apartment according to the woman?
