   M: Well, hi, Mrs. Brown. How's your apartment working out for you?
   W: Well, Mr. Nelson. That's what I would like to talk to you about. Well, I want to talk to you about that noise! You see. Would you mind talking to the tenant in 4B and asking him to keep his music down, especially after 10:00?
   M: Oh. Who? Me?
   W: Why? Yes. The music is blaring almost every night, and it should be your job as a manager to take care of things.
   M: Hey, I just collect the rent. Besides, the man living there is the owner's son, and he's a walking refrigerator. Hey, I'll see what I can do. Anything else?
   W: Well, yes. Could you talk to the owners of the property next door about the pungent (刺激性的) odor drifting this way?
   M: Well, the area is zoned for agricultural and livestock uses, so there's nothing much I can do about that.
   W: Well, what about the...? That, that noise.
   M: What noise? I don't hear anything.
   W: There, there it is again.
   M: What noise?
   W: That noise.
   M: Oh, that noise. I guess the military has resumed its exercises on the artillery range.
   W: You have to be kidding. Can't anything be done about it?
   M: I've protested this activity, and these weekly activities should cease... within the next three to five years.
   W: Hey, you never told me about these problems before I signed the rental agreement.
   What does Mrs. Brown ask the man in Apartment 4B to do?
