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.

According to the passage, compared with Pleistocene carnivores in other areas, Pleistocene carnivores in the La Brea area
想请问郭培月老师。 这题本来选了D，回看的时候发现定位错误，重新定位首先锁定了They ruled out local bias because breakage data obtained from other Pleistocene sites were similar to the La Brea data这句，因为既有 other Pleistocene sites又有 La Brea，但是细看发现是讲similar不是difference。 再重新定位后又锁定第一段Researchers compared the number of tooth fractures in present-day carnivores with tooth fractures in carnivores that lived 36,000 to 10,000 years ago and that were preserved in the Rancho La Brea tar pits in Los Angeles. The breakage frequencies in the extinct species were strikingly higher than those in the present-day species.但是不太确定是不是这里，因为觉得它是在对比present-day的和以前的，不是在比La Brea和其他地方的

After several years of rapid growth, the healthy care company became one of the largest health care providers in the metropolitan area, while it then proved unable to handle the increase in business, falling months behind in its payment to doctors and hospitals.
tina老师可以来讲一下思路吗？这题是转折关系，和prove falling的关系。while和but应该没有意思上太大差别吧？我留下了CE，但是不知道怎么排除掉c有its paying，e是主语少了it。这里proved是省略了it was 表示被动吗？不确定要怎么排掉。麻烦老师解答一下。谢谢！
