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.

As criminal activity on the Internet becomes more and more sophisticated, not only are thieves able to divert cash from company bank accounts, they can also pilfer valuable information such as business development strategies, new product specifications, and contract bidding plans, and sell the data to competitors.
这题我有两个问题想请教一下。第一个是A的话，是一个倒装结构，thieves是主语，选A多了个they，这是不是就是两句了-两个主语没连词？（我明白应该不是-毕竟是正确答案，但是为什么不是呢）然后not only，but also这里的but是不是有时候可以省略？这个not only，but also有哪些是可以省略的呢？除了but以外还有么？谢谢老师！

While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.
B选项有两个困惑，前面比较部分补齐的话cost for other types of power plants.总感觉这里的for别扭，远远不如of啊！第二they代指nuclear plants用单数吧？不然ACD为何都用的it呢！老师解答下。谢谢

Some anthropologists believe that the genetic homogeneity evident in the world's people is the result of a "population bottleneck"—at some time in the past our ancestors suffered an event, greatly reducing their numbers and thus our genetic variation.
A和B对比 我仔细听了其他老师的回复，感觉还是没听到关键点，英吉老师说causing有问题，容易认为是前面主语发出的，其实是event发出，所以排除。。。。不太认同这个排除法，因为前面整件事导致的causing也说得通，没有任何语法错误。不会从AB中取舍

For years the beautiful Renaissance buildings in Palitito have been damaged by exhaust from the many tour buses that come to the city. There has been little parking space, so most buses have idled at the curb during each stop on their tour, and idling produces as much exhaust as driving. The city has now provided parking that accommodates a third of the tour buses, so damage to Palitito’s buildings from the buses’ exhaust will diminish significantly.

Which of the following, if true, most strongly supports the argument?
老师，我是这样想的:B选项是排除了其他可能会damage building的因素，不就是相当于加强了这道题的结论-damage会减少了吗?为什么这道题不选B呢？
