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?

The illegal lobster harvesting was not so extensive that the
population of catchable lobsters in Belukia’s territorial waters had
sharply declined by 1996.
The average annual lobster catch, in tons, of an outlaw fishing
boat has increased steadily since 1992.
Outlaw fishing boats do not, as a group, harvest more lobsters
than do licensed lobster-fishing boats.
The annual legal lobster harvest in Belukia in 1996 was not
significantly less than 9,000 tons.
A significant proportion of Belukia’s operators of licensed lobster-fishing
boats went out of business between 1992 and 1996.

没有找到讨论，所以贴出来求助，如果已有很详细的讨论，麻烦好心人给个链接。如果没有，麻烦给个思路。我一开始选E，后来觉得E肯定不对，因为题目都已经说了there being no reduction in the level of legal lobster fishing activity.但是对于答案A，我一点思路都没有。请赐教

I have got the point about this question.
