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.

Normally a bone becomes fossilized through the action of groundwater, which permeates the bone, washes away its organic components, and replaces them with minerals.
接着刚才听完您的解答，我理解的意思是ing的动作发出者可以是主句的主语，也可以是主句的一套主谓（表示这件事的结果），但是不可以是主句的宾语或者修饰成分（比如本题的介词短语）？ 问题2:我的思路是the action of ground water影响了bone,通过题干里面的一系列动作，所以应该选A，用which来修饰the action of ground water这个整体？这样想对吗？还是有点不太理解为什么不选E，我在OG其他ing考点也有类似迷惑，看来是这个考点掌握的不好，麻烦老师再给讲解下，谢谢。

In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria's roads but are involved in 12 percent of all highway fatalities.  The very largest trucks—those with three trailers—had less than a third of the accident rate of single-and double-trailer trucks.  Clearly, therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks.
 
Which of the following, if true, most seriously weakens the argument?
⁥
想向老师请教这题的A选项，它是说这个车目前只在某些highway上用，没说以后不能用，那以后提高这个车的使用不就能降低死亡率了？为什么能weaken原文呢？我看到so far就把A选项排掉了，请老师指正我的思路。

During the earliest period of industrialization in Britain, steam engines were more expensive to build and operate than either windmills or water mills, the other practicable sources of power for factories. Yet despite their significant cost disadvantage, steam-powered factories were built in large numbers well before technical improvements brought their cost down. Furthermore, they were built even in regions where geographical conditions permitted the construction of wind- and water-powered factories close to major markets.

Which of the following, if true, most helps to explain the proliferation of steam-powered factories during the earliest period of industrialization in Britain?
请英吉老师回答。本体在C和E中徘徊，最后错选了C。E我理解的是抬杠，题目中furthermore 说steam factory 建在地理条件允许建立wind和water factory 的地方，但是E中又说这些能建造wind 和water的地方数量不够？本来就数量不够，为什么还要建steam factory? 没明白E的逻辑

Snowmaking machines work by spraying a mist that freezes immediately on contact with cold air. Because the sudden freezing kills bacteria, QuickFreeze is planning to market a wastewater purification system that works on the same principle. The process works only when temperatures are cold, however, so municipalities using it will still need to maintain a conventional system.

Which of the following, if true, provides the strongest grounds for a prediction that municipalities will buy QuickFreeze’s purification system despite the need to maintain a conventional purification system as well?

In1852 Robert Angus Smith published a detailed report
of the chemistry of rain kin a large area around the city of
Manchester, England ,noting that the closer one came to
town, the more the city air would become increasingly acidic
想问慧雯老师4个问题： 1.正确选项B里的one指什么？（前面是city air不是city呀，不能指city吧） 2.我错选C，认为coming closer to town可以是后面the city air发出，所以没错。请问coming的修饰有不准确吗？还是应该根据“完整性”的“谁干了什么”，把coming closer提到句子主干部分，不应做修饰成分。 4.代词one怎么用，前边代替的名词必须是单数？还是复数也行；只能代替前边出现过的名词？还是比较随意，可代替前边没出现过的名词，只要句意清楚也行？ 谢谢慧雯老师

The passage supports which of the following statements about sixteenth-century European fishing crews working the waters off Newfoundland?

请问郭老师。这题我定位在What is fairly certain, even though they left no written evidence of having done so, is that the first Europeans to conduct such trade during the modern period were fishing crews working the waters around Newfoundland.感觉这句里找不到答案，但是后句开始讲其他事实了，觉得后面会和题目无关。review的时候才发现答案在后面第二句。我在考场上要如何避免犯这种错误呢，有什么提示指明要继续往下读吗？...

The passage suggests that methiocarb and metaldehyde would be more effective as slug poisons if it were true that they
请问郭老师。这题我定位到Thus, both neurotoxins, while somewhat effective, interfere with the slugs' feeding behavior and limit their ingestion of the poison, increasing the probability that some will stop feeding before receiving a lethal dose. 这句了，但是当时虽然看到effective，但它只在让步状语从句里面，所以觉得这句话重点不是在讲effective。但是全文只有这句相关所以还是定位在这里。然后还是完全miss了正确选项，特别是看到only这个词更确定这是个错误选项。我把注意力都放在了影响进食行为和消化上，感觉后半句是表伴随的会没那么重要，选了B，不知道C要怎么选出来？

According to the passage, the congressional action of 1871 had which of the following effects?
想请问郭老师。这题题目的意思是1871年国会的行为有什么影响呢，还是只是在问国会的行为之后发生了什么。我对following effects这个词把不准,感觉在文章中定不出准确位置。我一开始定位在Many commentators believe that this change had already occurred in 1871 when - following a dispute between the House and the Senate over which chamber should enjoy primacy in Indian affairs - Congress abolished the making of treaties with Native American tribes. 定位后看到后面But in reality第一反应觉得答案是在这句，但看不出这句讲的事情是受国会行为的影响。因为他讲在国会行为后negotiation依然在继续，那意思不就是国会的行为没有任何影响吗......
