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?

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.

Industrialization and modern methods of insect control have improved the standard of living around the globe while at the same time they have introduced some 100,000 dangerous chemical pollutants, having gone virtually unregulated since they were developed more than 50 years ago.
為什麼不是B？gone unregulated不應該是對應methods？regulate methods regulate pollution没用过regulate pollutants这个说法很奇怪？

Among lower-paid workers, union members are less likely than nonunion members to be enrolled in lower-end insurance plans imposing stricter limits on medical services and requiring doctors to see more patients, and spend less time with each.
 
请教Tina老师，听到之前的录音讲解大致明白了，能够抓住impose与require的并列，也能接受see more patients 与spend less time这种并列不好，二者之间存在一种层级的关系。但是想请教一下老师，A选项imposing与requiring的用法为啥不好分清楚谁是主语呢？一直比较困惑于动名词的修饰，感觉在这里imposing好像并无不妥，特此请教老师，谢谢！

In the past several years, astronomers have detected more than 80 massive planets, most of them as large or larger than Jupiter, which circle other stars.
请教Tina老师，本题在CD中纠结，最终错选D。排C的原因是circling应当跟的是主句或主句主语以及that连接的从句或从句主语，但是题目中想说的是行星转动，因此感觉circling修饰到planet上的用法很怪，故排除；关于D选项，因为circle是复数形式，所以不修饰Jupiter,可以修饰到离其最近的复数planets上，虽然感觉隔得远，但也可以，感觉最起码比C的 ，circling要好，所以选了D。望老师指正，谢谢！
