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.
A选项中who跟在volunteers后面，所以可能理解成是是volunteers发出ponder的动作而不是researchers? 关于A选项的who包括E选项的they的指代对象麻烦老师讲一下。

In the mid-1920s the Hawthorne Works of the Western Electric Company was the scene of an intensive series of experiments that would investigate changes in working conditions as to their effects on workers' performance.
这题我选择了D，原因是以为experiments后面应该跟一件事情所以就以为要跟that，只剩下a与d，由根据would用的不好，所以选择了A。正确答案选B，我想求证一下正确的做题步骤：如果我重新做的话，我不会根据invrstigating的形式来判断，因为很难确定，但是我会根据句子的中心来判断。A中：investgate changes B中 investigate effects 然后用一件事情来说明这个effects 就更佳的清晰。C强调的也是 changes，且what the effects用的也不好。 D 强调的也是changes，E中 what the effects用的也不好。请问老师 是否我的做题思路是否正确，请指正。

The kinds of hand and wrist injuries that result from extended use of a computer while maintaining an incorrect posture are common among schoolchildren in Harnville. Computers are important to the school curriculum there, so instead of reducing the amount their students use computers, teachers plan to bring about a sharp reduction in the number of these injuries by carefully monitoring their students' posture when using computers in the classroom.

Which of the following would it be most useful to know in order to assess the likelihood that the teachers' plan will be successful?
C和E E错答无法归类.. 是不是原文说：目的减少injuries 通过监控姿势；而E说现在已经有正确姿势的proportion；就算现在proporation高，也不能说明plan不会成功？ 感觉好像是有点抬杠 但当时做题的时候觉得既然 现在都是正确姿势了，Plan再矫正正确姿势就不会成功。还请老师解释。

The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual that, in turn, create unconscious physiological responses.
请问Tina老师，这道题A选项that跳过了介词短语修饰前面的名词，同样的道理，C的v-ing 形式为什么就不对了呢？如果是因为A中有单复数的提示所以可以跳过介词短语，那么图中这道题的正确选项是c，其中没有任何提示也跳过了介词短语for private conversation 。所以本题是因为C和A对比之后A中有跳过提示所以更好吗？还是说v-ing形式修饰就不能跳过介词短语？谢谢老师

The steel industry has changed radically over the last two decades, as large, integrated companies such as Bethlehem Steel once conducted operations from mining at one end of the process to shipping at the other have greatly downsized, or in some cases shut down altogether.
请王文静老师回答一下这个问题，谢谢！ 请问老师题目要表达什么语义？ 我理解：近20年来的steel industry发生了巨大的变化，一些大企业要么缩减规模了要么就是完全倒闭了。decades后的句子是前边现象的具体描述，是个附属修饰，所以选了C。 with表示附属修饰的时候后边是不是不能加句子？ 选B的话decades前后句是因果关系？as是因为的意思？体会不出来有这层因果关系… 还是as是其他啥意思？
