【正确答案】 B

【答案解析】[听力原文]
   W: Hi. We've just moved into the building and I wanted to know about the trash pickup policy.
   M: Certainly. Trash is picked up twice a day at 2:30 p.m. and 8:30 p.m. We ask all residents to leave their garbage in tied plastic bags in the bin located outside just past this security desk.
   W: OK, so I need to leave all my trash outside the building in the bin. Got it. Is there anything else I should know?
   M: We ask that you don't leave any garbage outside your doorway or in other common areas of the building. And also, don't forget to separate your recyclables—cans, plastic and paper. You can put all those in a separate bag and leave them next to the garbage bin.
选项A错误，every other day意思是“每隔一天”，也就是每周4次。选项B正确，男士提到垃圾每天清理两次。选项C和D对话中均未提及。
