M: Good evening, and thank you for inviting me here this evening.
Q: What is the woman doing?

18. M: I'm looking for an apartment with a monthly rent to around 200 dollars in this neighborhood. Can you give me some advice on that?
W: Well, it's rather hard to find anything for less than 300 dollars here. Rents are lower in the suburbs, but you'll need transportation if you choose to live there.
Q: What do we learn from the conversation?
解析：D。男士问女士建议，女士说：“很难在附近找到房租低于300美元的房子”，言外之意是合乎男士要求的房子很难找。答案为D。
