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

ANS A

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. 应该翻译成：非法捕捞龙虾并不是很多，没有使得可捕捞的龙虾的数量在1996年急剧下降。

In 1992 outlaw fishing boats began illegally harvesting lobsters from the territorial waters of the country of Belukia. 简译：1992年开始有非法捕捞龙虾。

Soon after, the annual tonnage of lobster legally harvested in Belukian waters began declining; 简译：合法捕捞的龙虾数量开始减少。

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. 简译：1996年，合法捕捞活动并没有减少，但所捕捞的总量比1992年少了9000吨。

因此推断：therefore highly likely that the outlaw fishing boats harvested about 9,000 tons of lobster illegally that year. 简译：1996年的非法捕捞数为9000吨。

这说明龙虾的总量没怎么变化。如果总量Total变了，那就不是illegal＝Total－Legal了。所以选A
