Q11

In 1992 outlaw fishing boats began illegally harvesting lobsters from the territorial waters of the countru of Belukia. Soom after, the annual tonnage of lobster legally garvested inBelukian waters began declining; in 1996, despite there being no reduction in the level of legal lobster fishing activity, the local catch was 9000tons below pre-1992levels. It is therefore highly likely that the outlaw fishing boats harvested about 9000 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 inBelukia's territorial waters had sharply declined by 1996.

B. The average annual lobster catch, in tons of an oulaw 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 9000 tons.

E. A signigicant proportion of Belukia's operators of licensed lobster-fishing boats went out of business between 1992 and 1996.

答案给出的是A 为什么啊？~~~~

文中观点：1992-1996，因非法捕捞增加，造成合法捕捞的量变少。96年合法的少捕了9000吨，推论出：1996年，非法的船捕到了9000吨。
A. The illegal lobster harvesting was not so extensive that the population of catchable lobsters inBelukia's territorial waters had sharply declined by 1996.
A对，是因为非法船只并没有多到降低龙虾产量。跟文中观点相符合： “96年合法的少捕了9000吨，非法的捕到了9000吨。说明，龙虾的产量并没有下降，而是被非法的船给捕捞了。”
B. The average annual lobster catch, in tons of an oulaw fishing boat has increased steadily since 1992.
从文中看，到96年，捕捞的总量也没有增加。而合法捕捞的量更是减少的。所以B错。
C. Outlaw fishing boats do not, as a group, harvest more lobsters than do licensed lobster-fishing boats.
这个到底有没有多，和多多少，不知道。文里提都没提。
D. The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9000 tons.
这个数字不知道，文中两次提到的9000吨跟D没有关系。
E. A signigicant proportion of Belukia's operators of licensed lobster-fishing boats went out of business between 1992 and 1996.
文里没提

解释得非常清楚，感谢！！
再回头看A，觉得这就是对题干第一句话的重复，95年那个事就是一个example。

题干说：合法渔民少捕的鱼=非法捕的
A说：合法渔民少捕的鱼=非法捕鱼量+鱼本身的产量减少，这个公式里鱼本身产量为0.

豁然开朗，谢谢了。
