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 part of major renovations to Flowertown's Main Street train station, consultants to the train company proposed moving the station's entrance from its current valuable Main Street location to a low-rent adjoining side street and then leasing the high-rent entrance space to retail businesses.  In that way, the train company could easily pay for those and all other proposed renovations without negative impact on its tight budget.
 
Which of the following, if true, would most strongly support the consultants' proposal?
这道题我理解的是company选择移动位置主要关注的是budget, 也就是公司花的钱。然后最后我在a和b中错选了a, 也是因为a讲的是公司花费的钱，而b是关于公司revenue或者是profit的事情，然后我就觉得a更好。我想问下老师这题我的思路是哪里错了呢？

Certain groups of Asian snails include both “left-handed” and “right-handed” species, with shells coiling to the left and right, respectively. Some left-handed species have evolved from right-handed ones. Also, researchers found that snail-eating snakes in the same habitat have asymmetrical jaws, allowing them to grasp right-handed snail shells more easily. If these snakes ate more right-handed snails over time, this would have given left-handed snails an evolutionary advantage over right-handed snails, with the left-handed snails eventually becoming a new species. Thus, the snakes’ asymmetrical jaws probably helped drive the emergence of the left-handed snail species.

Which of the following would, if true, most strengthen the argument that asymmetrical snake jaws helped drive left-handed snail evolution?

老师麻烦解释下a选项，我觉得是其他蛇不吃蜗牛 所以对蜗牛进化没影响，所以其实增加了不对称蛇的导致进化的可能性。类似于“你的同桌不是美女”。所以在做题过程中 我最后留下了a和e，在当时的理解精度下我就觉得e是重复原文，所以最后选了a

我理解题目意思是说不对称的蛇是否促使了左手蜗牛的进化。而a选项说其他的蛇不吃蜗牛，所以其他的蛇不会导致蜗牛的进化。也就是增强了不对称的蛇可能促使了进化的可能性。类比于“你的同桌不是美女”。 我也觉得e是重复原文。请老师不要不答重复原文的解释问题。我现在很多题都是分不清重复原文和支持中搞混。比如691的a选项，694的a选项。对我来说都是重复原文，但是有的就是正确选项，有的不是。如果我分不清楚重复原文和支持原文的区别，那我会每道题都选可能重复原文那个选项。因为那个是最贴近问题的。所以还请老师解释一下这两者区别。或者考场遇到这样的问题怎么解决。
