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.

Editorial in Krenlandian Newspaper:
 
Krenland's steelmakers are losing domestic sales because of lower-priced imports, in many cases because foreign governments subsidize their steel industries in ways that are banned by international treaties.  But whatever the cause, the cost is ultimately going to be jobs in Krenland's steel industry.  Therefore, it would protect not only steel companies but also industrial employment in Krenland if our government took measures to reduce cheap steel imports.
 
Which of the following, if true, most seriously weakens the editorial's argument?
K的steelmaker的国内销量正在减少，因为便宜的steel被进口，他们便宜是因为外国政府违反treaties.K的steelmaker损失的代价也反映在jobs上，因此如果政府采取措施减少这些便宜货的进来，不仅能保护这个industry,也能保护employment。 C相关是因为它也说的是cost吗

Which of the following, if true, would indicate the most serious weakness in the plan above?
我把我的做题过程大概说一下，麻烦老师能够给与解答~ 先读题，题目说的大致意思是： 科学家们想要用一种办法降低大气中的二氧化碳，这种办法就是用plant life这个东西去吸收。为了完成这个计划采取的方案就是在海上建造大型的海藻farms，然后说当过这个plantlife死了以后可以当做燃料给烧了。 问题是问那个可以weaken这个论述 我读的选项： A海上的有些地方缺什么所以不能建farms B说当把这个plantlife少了以后他会放出和以前吸收的量差不多的二氧化碳 C说尽管这个东西有效率但是有些人不想干 D具体数量不管，大致方向是说最后每年吸收的没有排放的多 E说是这个farms可以赚钱云云，无关 我的分析思路： 选项读完以后也就举得BC沾边，但是B说的感觉是最后结果不增不减，但是C说的是最后还是排出的多（坏的更厉害，B至少几乎不怎么变），而题目问的是weaken，所以就选了C。 麻烦老师解答一下。

Driving the steep road to the mountaintop Inca ruins of Machu Picchu is potentially dangerous and hiking there is difficult.  Now the Peruvian government is installing a cable car that will make access much easier, and hence result in a large increase in tourism.  However, since the presence of large numbers of tourists tends to accelerate the deterioration of a site, installation of the cable car is certain to result in harm to the ruins.
 
Which of the following, if true, most seriously calls into question the argument?
请老师帮助比DE, 原文说cable car对那个地方造成损害，削弱。那么我想就是找其他原因。 D 天气原因 E cable car 取代tour bus ,tour bus 轱辘大对地方损害大。 然后我就想，这两个选项都提到了其他原因进行了削弱，然后我就蒙了
