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.

Australian embryologists have found evidence that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolving as a kind of snorkel.
1、听了之前的录音，我想把自己的做题思路和老师交流一下，看是否存在疏漏点。语义上面读出来原句表达的是大象从一个海洋生物进化以及象鼻子进化的事情两者并列。a选项用到and，后面不是句子，但是语义上应该并列，语法上不并列，杀a；b选项和c选项都变成了附属修饰，而语义上面两者谁都不埃谁，是分别的两件事情，所以附属修饰错，杀bc；d选项and连接的并列对象变成found和found并列，也就变成找到证据暗示以及找到证据；e选项说的语义是找到证据暗示a以及暗示b，语义上相比d说的更加精确，对比下来选e。 2、这道题听之前tina老师的录音说这里its指代有误，但是我认为这里its没有问题。因为本身trunk就是象鼻的意思，语义上its只能指代elephant，不可能指代海洋生物。所以我并不是通过its来排选项的。请老师帮我分析下its到底有没有指代不清的情况谢谢。

Editorial:
 
Regulations recently imposed by the government of Risemia call for unprecedented reductions in the amounts of pollutants manufacturers are allowed to discharge into the environment.  It will take costly new pollution control equipment requiring expensive maintenance to comply with these regulations.  Resultant price increases for Risemian manufactured goods will lead to the loss of some export markets.  Clearly, therefore, annual exports of Risemian manufactured goods will in the future occur at diminished levels.
 
Which of the following, if true, most seriously weakens the argument in the editorial?

Public health expert: Increasing the urgency of a public health message may be counterproductive. In addition to irritating the majority who already behave responsibly, it may undermine all government pronouncements on health by convincing people that such messages are overly cautious. And there is no reason to believe that those who ignore measured voices will listen to shouting.

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?
为什么a选项不对？？A不是直接解释了为什么即需要新的也需要旧的？ 因为新的只能kill bacteria， 所以还要保留旧的，因为还有其他东西要清除。 而c选项只是说了在冷环境旧的不那么好用，我那如果新的好用，这样也可以不用旧的。虽然说c也可以说在高温时候旧的就好用 但是这样理解和A就没什么太大区别。都应该可以吧
