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?

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.

请问王文静老师，读原文，第一段讲了一个现象，温度比预料的要底，又提出一种可能的解释：由于材料是粘土而不是大理石什么的，所以产生的热量比较小。第二段讲B做了一个实验，结果石头的材质不同产生的热是相同的，推翻第一段可能的解释，于是科学界就想是不是别的原因。这道题我选的A，我明白A为什么错了，但我觉得D也不太对，课视根据我所读的，感觉名没有表明SAF不是通过摩擦生热啊，文章只是说明了不是材料，而是压力影响摩擦，而没有否定SAF经过摩擦生热啊。

Books in European libraries last longer than books in libraries in the United States because, although the climate in Europe is fairly humid, libraries there are not subjected to the extremes of temperature and humidity that damage collections in the United States.
这题选的时候因为记得之前有道题说是be subject to是个固定搭配，所以直接排除了正确选项，所以这题里be subject to并不是主要的区分点么？因为这个词组本来就有点不太好区分，所以什么情况下会把这个作为一个区分点呢？

Delta products, Inc., has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity.  The question has been raised whether it can be concluded that for a given level of output, Delta's operation now causes less fossil fuel to be consumed than it did formerly.  The answer, clearly, is yes, since the amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount needed to power the older technologies, provided that the level of output is held constant.
