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.

In countries where automobile insurance includes compensation for whiplash injuries sustained in automobile accidents, reports of having suffered such injuries are twice as frequent as they are in countries where whiplash is not covered. Presently, no objective test for whiplash exists, so it is true that spurious reports of whiplash injuries cannot be readily identified. Nevertheless, these facts do not warrant the conclusion drawn by some commentators that in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious. Clearly, in countries where automobile insurance does not include compensation for whiplash, people often have little incentive to report whiplash injuries that they actually have suffered.

In the argument given, the two boldfaced portions play which of the following roles?

Humans get Lyme disease from infected ticks. Ticks get infected by feeding on animals with Lyme disease, but the ease of transmission from host animal to tick varies. With most species of host animal, transmission of Lyme disease to ticks is extremely rare, but white-footed mice are an exception, readily passing Lyme disease to ticks. And white-footed mouse populations greatly expand, becoming the main food source for ticks, in areas where biodiversity is in decline.

The information in the passage most strongly supports which of the following?
想选A 原文说人们有L疾病是因为被感染的tick 。 然后被感染的tick是由于吃了带L疾病的动物。 所以能归纳出A 当人们感染L疾病时，被L感染的tick相对较多。 请老师解答

Starfish, with anywhere from five to eight arms, have a strong regenerative ability, and if one arm is lost it quickly replaces it, sometimes by the animal overcompensating and growing an extra one or two.
我重复听了几次讲解，麻烦还请老师确认一下我这么理解对么？ 之所以CDE里的代词they不对，是因为they不能指代回前面的starfish。因为comma+and if把整个句子隔成了两个clause，后半部分的代词必须要服从后半部分里的名词one arm/the animal（根据语义肯定是one arm），而不能跳跃去指代句子里and if前面半部分里的名词starfish，所以要用单数代词。这么理解对么？考场上见到类似情况，可以通过这个规律（and 后面出现的代词只能指代and后面部分里的名词）来杀掉选项吗？ 还有一点没太听明白的是overcompensating和growing的关系，它们之间不是因果关系么？B里面用and连接不就是变成并列了么？为什么并列对呢？ 我以为是先overcompesating，再growing，有先后因果关系，所以选了C
