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.

有老师建议直接猜多元推理题，因为它比较难，又耗时。请问每次考试中这种题的出题模式固定吗？每次会来几题呢？或者说每次会来几篇文章呢？每篇文章有几个题的数量都固定吗？我有点怕把别的相对容易的题型误判成多元推理题，本应该认真做的题确直接去猜了，所以想问一下这种题目的特点是什么？在刚看到一个题目时，如何有效判断出是否这种题型?

请问这道题as后为何不能省略they are呢？ 对语法题中的省略方法一直有困惑。我现在的理解是这样的:如果各选项其他地方有明显的语义差异，那么其次再考虑省略是否正确；如果各选项没有明显的语义差异，那么只有重复的部分才可省略。不知道这样理解对不对，恳请老师指教语法题中“省略”的判断方法。

我听了之前的录音还是不能理解。我纠结的在于，这种问一句话里面，画了半句话的作用的题，从解题思路上来看应该可以从句内逻辑关系和句子在文中的关系两个方面来理解吧。这句话显然在句内就有转折呀，划线明明只花了半句，怎么能展现出整句话起到的作用呢。这让我想到OG18，P392上讲resin的那篇文的470道题，也是一个although引导了半句话，和这道题类比的话，470这题不是也不应该选D嘛。
