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.

The passage suggests that the fact that ALH84001 has been on earth for 13,000 years has been used by some scientists to support which of the following claims about ALH84001?
文章逻辑是：1994年D M领导的一队科学家，开始研究ALH84001.两年后，M这些人宣称ALH这个东西（generally都认为是来自于火星的）能表明，火星上有生命迹象。（what类细节支持，证据里面都包括，发现有机细胞组织，成分构成等等。当微生物死掉，有机物质会变成PAH） 第一回合：有一些人就质疑M队的结论（不是来自火星的更证明不了火星上有生命）。比如：ALH这个东西在地球上很久很久了。但M队举证，他们找到的来自火星的ALH跟地球上的不一样。 第二回合：那些质疑M队的人，很多过程都会导致M队所谓的证据的产生（所以可并不一定都是来自火星的），what类细节比如L35-39 M队说PAH的特殊构成更像是因什么形成的，而不是非生物过程形成的。错选了B，细节定位没有定位对读错了导致的。我的问题1:我还是读的偏细节，我正在努力提高总结能力，您看如何提炼原文逻辑链更好些？问题2: 请老师协助对应一下如何从正确的地方推导出正确选项。谢谢

想问下老师，这种问primary purpose是怎么做的，我选的是D，这个D我是根据前面判断的，我觉得C那个hypothesis仅仅是随着一些东西的发现后面推出来的，可是没有前面就没有后面呀，是不是问这种primary purpose的题目是根据最终的一个观点或现象来做判断还是根据文章大部分的段落句子在讨论的东西做出判断，如果是比如这篇文章改下，后面也是提出hypothesis，不过只是几句话带过，也否定了前面的东西，修饰的语句少了，是不是就不能选这个选项了？
