【正确答案】 B
【答案解析】[听力原文]
   W: Mr. Stevens, yes, you're on the list for this morning's auction. Here are your bidding sheets. At the Smith Street Fish Market, we use a Dutch auction—Do you know what this is? No? Alright, see those clocks on the back wall? The clock starts at the highest asking price and drops until someone bids. Once that person bids, the auction for that particular item is over. All bids are final, and everything happens in a blur, so watch a few transactions and acquaint yourself with the process before you start bidding. Your approved credit limit is $650. To make a bid, type your PIN—yours is 3328—and give him or her one of those bidding sheets I just gave you. Your products will be brought to the warehouse freezer, but you can go to the loading dock and request to pick up your purchase at any time. If you have any questions, ask anyone wearing a blue vest.
选项A、C和D都错误。选项B正确,女士称拍卖点在Smith Street Fish Market。
