In 1992 outlaw fishing boats began illegally harvesting lobsters from the territorial waters of the country of Belukia. Soon after, the annual tonnage of lobster legally harvested in Belukian waters began declining; in 1996, despite there being no reduction in the level of legal lobster fishing activity, the local catch was 9,000 tons below pre-1992 levels. It is therefore highly likely that the outlaw fishing boats harvested about 9,000 tons of lobster illegally that year. Which of the following is an assumption on which the argument depends? A. The illegal lobster harvesting was not so extensive that the population of catchable lobsters in Belukia’s territorial waters had sharply declined by 1996. B. The average annual lobster catch, in tons, of an outlaw fishing boat has increased steadily since 1992. C. Outlaw fishing boats do not, as a group, harvest more lobsters than do licensed lobster-fishing boats. D. The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9,000 tons. E. A significant proportion of Belukia’s operators of licensed lobster-fishing boats went out of business between 1992 and 1996

题目里好象没有说1992年以来非法捕捞平均量在STEADILY增加吧，这个STEADILY是很有问题的啊。

A的意思是，非法捕捞并没有多到让龙虾数量急剧减少的程度。这样就正好说明了题意，因为龙虾总数量不变，合法捕捞减少的龙虾数量就正好被非法捕捞的人给弄走了。
