In1992 outlaw fishing boats began illegally harvesting lobsters from theterritorial waters of the country of Belukia. Soon after, the annual tonnage oflobster legally harvested in Belukian waters began declining; in 1996, despitethere being no reduction in the level of legal lobster fishing activity, thelocal catch was 9,000 tons below pre-1992 levels. It is therefore highly likelythat the outlaw fishing boats harvested about 9,000 tons of lobster illegallythat year.
Whichof the following is an assumption on which the argument depends?
A. The illegal lobster harvesting was not so extensive thatthe population of catchable lobsters in Belukia’s territorial waters hadsharply declined by 1996
B. The average annual lobster catch, in tons, of an outlawfishing boat is has increased steadily since 1992.
C. Outlaw fishing boats do not, as a group, harvest morelobsters than do licensed lobster-fishing boats.
D. The annual legal lobster harvest in Belukia in 1996 was notsignificantly less than 9,000 tons.
E. A significant proportion of Belukia’s operators of licensedlobster-fishing boats were out of business between 1992 and 1996
在1992年 不法渔船 开始 非法 从Belukia 领海捕捞龙虾。之后，每年的从Belukian 非法捕捞的吨数开始下降。在1996年，尽管，非法的捕龙虾活动 没有减少，但是当地的捕捞 为9000 吨，少于1992年之前的吨位。因此，很可能，非法捕捞的船只在那年非法捕捞了，大约9000吨龙虾。
问假设。
A、非法捕猎龙虾没有十分猖獗以至于在Kelukia 领海范围可捕盗的龙虾数量自1996年来大幅下降。
B、每只非法捕猎船，平均一年龙虾捕捉，以吨来计的话，自从1992年以来 稳步增长
C、非法捕猎船，作为一个群，比起合法龙虾捕猎船，捕猎更多的 龙虾。
D、1996年一年合法的龙虾捕捞 没有 显著少于 9000吨。
E、在1992年到1996年间，很大一部分合法的捕猎船只的经营者 退出了 市场。
