20世纪初,有一位名叫哈桑的利比里亚商人从挪威购买了12000吨鱼,当他把这些鱼运回国之后一过秤,发现少了47吨。这下这位商人迷惑了:这些鱼从装箱、上船、运输到卸货全过程都在自己的监视之中,途中被偷也是绝对不可能的。那么,这些少了的鱼哪去了呢? At the beginning of the 20th century, a Liberian businessman named Hassan purchased 12,000 tons of fish from Norway. When he returned the fish to the country, he weighed and found that 47 tons were lost. This merchant was puzzled by the fact that it was absolutely impossible for these fish to be stolen on their way from packing, boarding, transport to unloading all through the process. So where are these fewer fish?
