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.

Researchers studying the brain scans of volunteers who pondered ethical dilemmas have found that the basis for making tough moral judgments is emotion, not logic or analytical reasoning.
想问问Tina老师，这个题其实我想问问C 中有一个问题，就是volunteer pondering 这个pondering 是不是只能修饰 volunteer 因为我做了很多题发现如果这种doing放在一个名词后面的话，基本上就只能修饰这个名词，不像一句话＋逗号＋doing那种能修饰前句主语和前句整句话

The ancient Nubians inhabited an area in which typhus occurs, yet surprisingly few of their skeletons show the usual evidence of this disease.  The skeletons do show deposits of tetracycline, an antibiotic produced by a bacterium common in Nubian soil.  This bacterium can flourish on the dried grain used for making two staples of the Nubian diet, beer and bread.  Thus, tetracycline in their food probably explains the low incidence of typhus among ancient Nubians.
 
Which of the following is an assumption on which the argument relies?
反思： 原文没有怎么读太明白。 就记得结论是说在食物里的tetra 解释了低的ty的事件率对于Nubians来说。问的是假设。 A 说的是除了ty以外 的别的病菌。 无关 B 没太读明白 (好像是说 teracycline在被做成面包和啤酒后对于抵抗typus这种病，仍然不是没有效果的) 然是我做题的时候读了2遍没概念就知己掠过了。 C 选了C，因为C说了ty不能通过被污染的面包和啤酒传染。 D 面包和啤酒是这帮人只吃的东西。 无关。 E ty 致命 无关 经过排除剩下了BC，都说了食物和ty。感觉C好像是堵住了一个possibility的感觉？猜了C。 这种剩下2个选项，一个能读懂，一个读不太懂的情况怎么办。 谢老师！

The English physician Edward Jenner found that if experimental subjects were deliberately infected with cowpox, which caused only a mild illness, they are immune from smallpox.
想请Tina老师回答一下，就是causing这个词可以指代EJ 这个人，可以指代实验对象，也可以指代人们被感染了牛痘这件事，所以我认为causing也不算错呀，因为明显前两个指代对象不能causing，只能是人们感染这件事causing。虽然我也能理解which

Found only in the Western Hemisphere and surviving through extremes of climate, hummingbirds’ range extends from Alaska to Tierra del Fuego, from sea-level rain forests to the edges of Andean snowfields and ice fields at altitudes of 15,000 feet.
想请Tina老师解答一下，我选的是d 选项。虽然我也觉得有点怪怪的。但是别的选项更有问题。b选项前面一直在说这个bird，但是突然用range extending,就很怪啊。
