T-7-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?

1. The illegal lobster harvesting was not so expensive that the population of catchable lobsters in Belukia’s territorial waters had sharply declined by 1996

2. The average annual lobster catch, in tons, of an outlaw fishing boat is has increased steadily since 1992.

3. Outlaw fishing boats do not , as a group, harvest more lobsters than do licensed lobster-fishing boats.

4. The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9,000 tons.

5. A significant proportion of Belukia’s operators of licensed lobster-fishing boats were out of business between 1992 and 1996

答案为什么是A

啊呀，还是晕！

可捕捞的量=合法的量+非法的量

如果是A的话，可捕捞的量减少了，合法的量减少了9000的话，非法的量就肯定不是增加了9000啊...可是题目中最后一句的结论是It is therefore highly likely that the outlaw fishing boats harvested about 9,000 tons of lobster illegally that year.

相反的啊！...
