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.

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.

Advertising by mail has become much less effective, with fewer consumers responding. Because consumers are increasingly overwhelmed by the sheer amount of junk mail they receive, most discard almost all offers without considering them. Thus, an effective way for corporations to improve response rates would be to more carefully target the individuals to whom they mail advertising, thereby cutting down on the amount of junk mail each consumer receives.

Which of the following, if true, would most support the recommendation above?
不明白为什么B不行， 正确答案是E

A study on couples' retirement transitions found that women who took new jobs after retiring from their primary careers reported high marital satisfaction, more than when retiring completely.
问题1. 划线前已经是个完整的句子（that引导的），这里more so than those who retired与that引导的主句部分是什么关系？ 若是分句为啥两部分之间没有连词？ 问题2 这里So指代的是退休女人“report high marital satisfaction”的意思嘛？ 所以More指代的就是more of退休之后再从事新工作的女人？

Hunter:  Hunters alone are blamed for the decline in Greenrock National Forest's deer population over the past ten years.  Yet clearly, black bears have also played an important role in this decline.  In the past ten years, the forest's protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer.
 
In the hunter's argument, the boldface portion plays which of the following roles?
答案是A，选了B。 把第一句话当做了conclusion, 觉得第二句应该是跟第一句反的，所以是反对conclusion的。为什么把第一句和第二句放在一起当做是一个conclusion? 谢谢

Economist:  Tropicorp, which constantly seeks profitable investment opportunities, has been buying and clearing sections of tropical forest for cattle ranching, although pastures newly created there become useless for grazing after just a few years.  The company has not gone into rubber tapping, even though greater profits can be made from rubber tapping, which leaves the forest intact.  Thus, some environmentalists conclude that Tropicorp has not acted wholly out of economic self-interest.  However, these environmentalists are probably wrong.  The initial investment required for a successful rubber-tapping operation is larger than that needed for a cattle ranch.  Furthermore, there is a shortage of workers employable in rubber-tapping operations, and finally, taxes are higher on profits from rubber tapping than on profits from cattle ranching.
 
In the economist's argument, the two boldfaced portions play which of the following roles?
thus 后面是 environmentalists 的conclusion. 第二个boldface 明白，第一个不太清楚为什么是supports了。在thus之前一句就是support了吗？
