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.

Which of the following most logically completes the argument given?
 
People in isolated rain-forest communities tend to live on a largely vegetarian diet, and they eat little salt.  Few of them suffer from high blood pressure, and their blood pressure does not tend to increase with age, as is common in industrialized countries.  Such people often do develop high blood pressure when they move to cities and adopt high-salt diets.  Though suggestive, these facts do not establish salt as the culprit in high blood pressure, however, because _____.

Last year a chain of fast-food restaurants, whose menu had always centered on hamburgers, added its first vegetarian sandwich, much lower in fat than the chain’s other offerings. Despite heavy marketing, the new sandwich accounts for a very small proportion of the chain’s sales. The sandwich’s sales would have to quadruple to cover the costs associated with including it on the menu. Since such an increase is unlikely, the chain would be more profitable if it dropped the sandwich.

Which of the following, if true, most seriously weakens the argument?
选了c 请问为什么答案是D D答案没有读出sandwich sale would quadruple并且覆盖成本的意思

One summer, floods covered low-lying garlic fields situated in a region with a large mosquito population. Since mosquitoes lay their eggs in standing water, flooded fields would normally attract mosquitoes, yet no mosquitoes were found in the fields. Diallyl sulfide, a major component of garlic, is known to repel several species of insects, including mosquitoes, so it is likely that diallyl sulfide from the garlic repelled the mosquitoes.

Which of the following, if true, most strengthens the argument?
请问c为什么不对？ 原文：大蒜地with a large mosquito population。水里没蚊子卵，大蒜驱蚊。 按c选项，大部分大蒜被杀了，所以蚊子有large population，属于支持。

Unlike most severance packages, which require workers to stay until the last day scheduled to collect, workers at the automobile company are eligible for its severance package even if they find a new job before they are terminated.
到底选D还是E，有官方答案吗😂 我听了每一个录音，有的老师说D有的老师说E。在网上也是争议题。我觉得E的问题是the last day they are scheduled to collect里的they指代没画线句子的workers，也就是“workers collect days”，语义不通。但如果说E代词指代有问题的话，D的their也不知道到底指代packages还是workers。到底这个句子的代词指代的是谁？D和E都有类似的模糊不清的地方。所以这让我很疑惑。
