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.

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.

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.

张老师，这个你那个阅读课里面第十二篇文章。关于是不是细节我处理出了点问题，文章第三段，第一句是k仔细检查了失业模型。第二句是他发现了失业率因阶级而异。第三句是但是这特定阶级内部的失业率影响也不同。第四句即使是在同一个trade里，失业率也不同，confirm里前一句。第五局k用these differential rates 去帮助解释困惑历史学家的现象，这里为什么不是下层细节呢？这句话核心语义是在于“用他的结论去做了件什么事”，并不影响主旨“他的这个结论是什么？”？第六句“但是mobility 不是主要的工人策略”，这里不知道mobility是什么，就返回上一句去看，看见出现在上一句，就觉得在解释上面下沉细节里面的内容是细节转折也就跳了这句。最后一句说的是自救，切入角度小，不读。所以根本没有读出作者在这里还对k怼了一句。这样处理不可以吗？但就是由于这样处理，也就没有读出最后一句前半部分为什么要说尽管还要花很多时间发展应用，这里就没有扣上。。。但实在不懂怎么知道那里就要去读了，感觉有点后面逻辑没有连得上，所以再说服自己该回去读那里的感觉，第一遍读的时候根本对这里没有感觉是逻辑转到了在说他的结论的应用。

An unusually severe winter occurred in Europe after the continent was blanketed by a blue haze resulting from the eruption of the Laki Volcano in the European republic of Iceland in the summer of 1984.  Thus, it is evident that major eruptions cause the atmosphere to become cooler than it would be otherwise.
Which of the following statements, if true, most seriously weakens the argument above?
原文说的是在火山爆发后，欧洲遭遇严冬。因此得出大的火山爆发导致了大气变的更冷。感觉是一个cause结构，由一个客观的严冬推理出是由火山爆发导致的。C说的是火山爆发会使得气温升高，等于驳斥了客观的结果，不对。D说的是气候变化可能掩盖了某个趋势，是个他因，所以选了D。
