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.

求助……我选了e，答案是c，做题过程是先判断evidence是一件事 ab排除，然后e中看到用emotions直接和heartburn对应，觉得更加清晰，所以选了e 我sc部分中其中一个薄弱就是对比题，对比对象总是会像这样弄错

Mourdet Winery:  Danville Winery's new wine was introduced to compete with our most popular wine, which is sold in a distinctive tall, black bottle.  Danville uses a similar bottle.  Thus, it is likely that many customers intending to buy our wine will mistakenly buy theirs instead.
 
Danville Winery:  Not so.  The two bottles can be readily distinguished:  the label on ours, but not on theirs, is gold colored.
 
Which of the following, if true, most undermines Danville Winery's response?
第一次浏览就排除了D选项，觉得各种有问题。首先是不客观啊，必须各种推导才能联系到原文主题。DW认为两种酒能区分，购买者不会买错，选项需要驳斥它；D说的是购买者基于酒瓶最明显的特征去购买酒。买不买错跟消费者怎么买之间必须推导才能建立关系。 不服求辩。

During the past year, Pro-Tect Insurance Company's total payouts on car-theft claims were larger than the company can afford to sustain.  Pro-Tect cannot reduce the number of car-theft policies it carries, so cannot protect itself against continued large payouts that way.  Therefore, Pro-Tect has decided to offer a discount to holders of car-theft policies whose cars have antitheft devices.  Many policyholders will respond to the discount by installing antitheft devices, since the amount of the discount will within two years typically more than cover the cost of installation.  Thus, because cars with antitheft devices are rarely stolen, Pro-Tect's plan is likely to reduce its annual payouts.
 
In the argument above, the two portions in boldface play which of the following roles?
