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 British sociologist and activist Barbara Wootton once noted as a humorous example of income maldistribution that the elephant that gave rides to children at the Whipsnade Zoo was earning annually exactly what she then earned as director of adult education for London.
王老师，我看刷题录播课里 您直接排除DE,说宾语从句缺引导词that，但是that作为引导宾语从句是可以省略的 您也知道的吧。。所以您这个排除的逻辑根本经不住推敲啊。。究竟是为什么？？

Journalist: In physics journals, the number of articles reporting the results of experiments involving particle accelerators was lower last year than it had been in previous years. Several of the particle accelerators at major research institutions were out of service the year before last for repairs, so it is likely that the low number of articles was due to the decline in availability of particle accelerators.

Which of the following, if true, most seriously undermines the journalist's argument?
请老师解释一下B和D哪里有问题，属于英吉老师说的驳斥题错误答案中的哪一类？

The Earth's rivers constantly carry dissolved salts into its oceans.Clearly,therefore, by taking the resulting increase in salt levels in the oceans over the past hundred years and then determining how many centuries of such increases it would have taken the oceans to reach current salt levels from a hypothetical initial salt-free state, the maximum age of the Earth's oceans can be accurately estimated.
 
Which of the following is an assumption on which the argument depends?
王文静老师好~~这道题我听了几个录音都是E，但我觉得还是选A，理由如下： 首先，原文是想要精准测量海洋的年龄，那么这题主要在考“精准测量”而不是“能不能测量”。从这个角度来看，E提到的他因有一点太猛了，直接把原文说的测量方法完全颠覆。 其次，从时态来看，A说的是过去一百年，E说的是一般现在时（或者可以理解为一种常态），而这次试验是在对过去累计的salt进行测量，所以我会觉得A更好。 在纠结AE的时候我就想到了这么多，然后选了A。请王文静老师指点，谢谢。

Unlike the virginal, whose single set of strings runs parallel to the front edge of the instrument, the harpsichord’s several sets of strings are placed at right angles to its front edge.
请问下Tina老师 这题，可不可以直接看句子最后的its front edge,因为its在五个选项里，唯一能对得上的只有harpsichord，而其他四个主语都是复数，可以这么做吗? 我知道这题考的其实是前面的主语平行，只是无意看到这里，不确定可不可以从后面来做

Laos has a land area about the same as Great Britain but only four million in population, where many are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.
请问下tina老师 如果第一句写成，laos has more land area than that of Britian, 这样是不是就错了，因为laos不能有britian的土地? 但这题选项e，comparable to可以类似于than，进行比较，但是这里是，has a land...然后进行比较，这样的话，可不可以理解成是宾语land area的比较?
