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.

People with a certain eye disorder are virtually unable to see in moderately bright light, which seems to them unbearably intense, since the cells of their retinas are overwhelmed by moderately bright light.  These people do, however, show normal sensitivity to most components of dim light.  Their retinal cells are also not excessively sensitive to red components of moderately bright light.
 
The information above best supports which of the following hypotheses about people with the disorder described, if they have no other serious visual problems?

Researchers agreed that the study of new treatments for heart attack patients was extremely important but more research was needed to determine that balloon angioplasty preceded with ultrasound was or was not any better for heart attack patients than the balloon procedure by itself.
第一次做选的C，第二次选的B。听之前的录音说选B，后来的录音说选C。答案是C。这次做的时候第一感觉是C，agree that 和 but that 并列，但是没有太大把握，所以看其他地方，上次排除B是因为觉得whether or not的表达不对，但是后来在文章中见过这种表达，所以这次没有根据这点排除B，其次对比than后面是否加is，原文说balloon angioplasty preceded by ultrasound is better，所以我认为后面应该是than balloon procedure by itself is，排除了C。在做对比题时，than后面是否加be动词，经常把握不好，不知道什么时候可以省。麻烦老师讲解。

In order to withstand tidal currents, juvenile horseshoe crabs frequently burrow in the sand. Such burrowing discourages barnacles from clinging to their shells. When fully grown, however, the crabs can readily withstand tidal currents without burrowing, and thus they acquire substantial populations of barnacles. Surprisingly, in areas where tidal currents are very weak, juvenile horseshoe crabs are found not to have significant barnacle populations, even though they seldom burrow.

Which of the following, if true, most helps to explain the surprising finding?
老师您好 这道题我的理解是这样的： 螃蟹为了忍受潮汐burrow在沙子里—这个burrowing的过程阻止了barnacles附着在背上—长大后，螃蟹可以忍受潮汐不用burrowing了，获得了barnacles—转折，在潮汐非常弱的地区，螃蟹没有barnacles，尽管他们很少burrowing 让解释这个现象 一开始我并没有想读懂，但是发现这道题在不读懂的情况下没法根据选项等等来做题。想请老师带着分析一下。

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.
AC对比，选了C，答案是A。A的that指的是极端的温度和湿度，应该是复数，当时也不知道怎么就感觉that只能指单数，而C说的as，我以为as后的主语可能省略了，就选了C。麻烦老师讲解。
