Q11:
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.
Answer: a 有个小问题，A我觉得是没错，但是解释起来有点怪：had后是不是应该有not才能使结论成立，要是按照我的翻译，就是A选项龙虾的数量减低了，那就不合题意啊，我看了天山的讨论帖，还是没回答我这个问题，请教斑竹
