【答案解析】[听力原文]
W: Hi, I have some product samples I want to send overseas. Could you tell me which option has the least expensive rate?
M: Well, overnight delivery shouldn't take mere than a day, but it is pretty expensive, regular mail takes five days to ten days. If you send it by ship, it's cheaper but it takes about 20 days.
W: Well, the samples have to arrive within three to five days. Besides, they are fragile items that need to be handled with caution.
M: If that's the case, overnight delivery would be the best. Regular mail might deliver it in a week or so, but it could take a little longer. Overnight delivery is much safer than other options.
