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.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

Caribou are wary animals with excellent hearing, so stalking them over the treeless landscape, getting close enough to kill it with nothing but a handheld lance, as Dorset people did, required exceptional hunting skill.
想问一下王老师，我理解为什么用“one”而不是“it”，也明白“in order to"会导致没有主语。但是这道题b选项正确的并列方式是不是应该是to get close enough？

In some species of cricket, the number of chirps per minute used by the male for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve as an approximate thermometer.
请唐瑭老师回答一下： 我根据动词rises和falls应该匹配number判断出应该在BDE中选，之后b中which后面的内容从语义上判断不应连接temperature，而是连接number，所以排除了B，之后DE就开始纠结，错选了E。后来我想了一下E错是因为serving可以修饰离它远一点的名词，这里有number和female和accordance，这样就会产生歧义。想问一下老师，我这样想对吗
