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.

Which of the following most logically completes the passage?
 
Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed.  The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases.  A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses.  Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since ______.

Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-rays because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When a number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fractures initially judged stable.

Which of the following, if true, most strengthens the argument?

这个题目我大致看成了这样：通常病人有stab关节fracture的不需要手术的，被给了一个后续x片因为有可能被误诊关于稳固性。当一个后续的x片被看时发现所有的stable处都正确愈合了。因此，很浪费钱去买后续x片关于那些一开始认为stable的。 A 有两帮医生p和o，p比o更不可能正确判断关节稳固性，这个强调的是p和o的比较，排除了； B 很多关节受伤被揭示发现没有任何fracture 这句话是在讲什么？按照一句话讲一件事的定义，他说的是injuries有没有fracture吗？ C x片属于病人的这个病人属于很多不同的o来自不同的医院被审核了。说实话这个我压根没有看懂 看文章的时候也不记得有o了直接跳过了 然后我觉得c只是说x片被看过来所以也排除了 D 讲的是愈合经常被一种方式检查 排除了 E o经常要后续x片关于fracture而不是ankle的，我觉得在讲x片怎么样了，好像沾边啊？ 就稀里糊涂的选了E 看了现有的解释没有一个是回答了我的问题的 请老师用第一遍做题的感觉帮我看一下我到底哪里出问题了 谢谢老师！ 读成这样能做题吗？
