题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

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?
请郭培月老师回答(⁎⁍̴̛ᴗ⁍̴̛⁎)谢谢~ 请问老师我这样考虑A选项是否正确：取非，非法捕太多导致可捕的总量大幅度下降了。可是我认为这样只能说合法的减少不完全是因为非法捕太多，也是因为可捕总量少了，对原文逻辑链并不能100%推翻。。 这道题怎么排除BCD选项？另外其实我也不懂为什么原文说合法的减少的9000吨就是非法捕的，不知道原文是怎么推出来的。。所以做这道题很懵~ 谢谢老师回答(˶‾᷄ ⁻̫ ‾᷅˵)
