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.

The passage mentions which of the following as a factor that affects the role of P. ochraceus as a keystone species within different habitats?
请教张慧雯老师，本题我的定位点和思路， Moreover, whereas P. ochraceus occupies an unambiguous keystone role on wave-exposed rocky headlands,in more wave-sheltered habitats the impact of P. ochraceus predation is weak or nonexistent, and at certain sites sand burial is responsible for eliminating mussels.同时把重点放在了这句话： Keystone status appears to depend on context, whether of particular geography or of such factors as community diversity (for example, a reduction in species diversity may thrust more of the remaining species into keystone roles) and length of species interaction (since newly arrived species in particular may dramatically affect ecosystems).大概的理解就是k的地位和地理要素比如diversity和 length of species interaction 挂钩，然后我就选了e，事后觉得这个选项within some habitats occupied by P. ochraceus可能有点问题，但是当时根据我重点关注的这句话我也觉得a和原文没关系（虽然上句话有提到），请老师指出我的问题。

Scientists have modified feed corn genetically, increasing its resistance to insect pests. Farmers who tried out the genetically modified corn last season applied less insecticide to their corn fields and still got yields comparable to those they would have gotten with ordinary corn. Ordinary corn seed, however, costs less, and what these farmers saved on insecticide rarely exceeded their extra costs for seed. Therefore, for most feed-corn farmers, switching to genetically modified seed would be unlikely to increase profits.

Which of the following would it be most useful to know in order to evaluate the argument?
请问张慧雯老师，本题我觉得他主要是围绕these farmers saved on insecticide rarely exceeded their extra costs for seed.杀虫剂的成本去谈，然后我就选了c 感觉他就是拿不同种类的corn的杀虫效果去比较，请老师指出我的问题。

Which of the following statements about the modernization of the telephone exchange is supported by information in the passage?
请教张慧雯老师，听了本题您上面的讲解，感觉这篇文章理解难度蛮大的，想问问这篇文章算是高分库的文章吗？因为考场上短时间内很难梳理结构，我第一次的定位在： the shape of a technological system is subordinate to the manager’s desire to wrest control of the labor process from the workers. Technological change is construed as the outcome of negotiations among interested parties who seek to incorporate their own interests into the design and configuration of the machinery. 应该是b那个人的观点了，第一次选了a。
