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.

D

Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.
老师，我错选D,我的解题思路是这样的，首先根据句子结构，排除B\C, and应该连接两个完整的句子，但这两个选项都缺少谓语，剩下的选项就找不到很明确的考点了。我听og精讲有提到通过判断句子重点来选择，但是判断句子重点一直是我很不敏感的事情，要怎样解决呢？另外，如果不通过判断句子重点，有其他考点来判断吗？这道题的正向解题思路应该是怎样的呢？谢谢老师！

Organized in 1966 by the Fish and Wildlife Service,the Breeding Bird Survey uses annual roadside counts along established routes for monitoring of population changes of as many as, or of more than 250 bird species, including 180 songbirds.
c,d选项相较于ade，少了“as many as”这层意思。就是说ade是population“大于等于”250，cd是population“大于”250。请问这一点会影响cd的可选性吗？ 谢谢。

For the first time in the modern era, non-Hispanic Whites are officially a minority in California, which amounts to a little less than half the population of the state, down from nearly three-quarters only a decade ago.
这道题错选了A，想问下老师，which可以指代前面的minority吗？如果这样这个句子的意思就不对了。所以选择D,直接修饰前句主语？

Faced with an estimated$2 billion budget gap,the city's mayor proposed a nearly 17 percent reduction in the amount allocated the previous year to maintain the city's major cultural institutions and to subsidize hundreds of local arts groups.
一上来就杀掉了A。觉得intended meaning应该是propose在I和local arts group减少17%预算，但是A里proposed...by 17%.. to...and to...是减少17%预算来赞助I和local groups，to理解成了“用来做什么事”。 觉得E里后面都是for...and for...，虽然一个for后面是动名词，另一个for后面是名词，但语义是对的，所以以为少许结构不平行没关系。 烦请老师解答我思考得哪里不对了。。。

Unlike mainstream American businesses, more than half of which fail, the failure rate for businesses in the Amish community hovers around 5 percent.
问的题目不是这一道。是我贴的这个。请问老师，这个题目。我根据代词指代将B和E排除。剩下A C D。问题来了，首先A用with附属修饰没有明确的逻辑关系，而CD用定于从句修饰fund，修饰精准度上CD更优秀，基金被计划虽然语义有点奇怪但还能接受。 C和D语义上差别不大，after exhausting exhaust的动词发起者也可以找到为Alaska,我就选了D。 但是答案是C， 我想问，Alaska为什么发不出exhaust的动作，它都可以发出deposits的动作，也应该理解可以发出exhaust呀。 还有A选项我也想问下，那个with the intention可以理解为修饰Alaska，但是我看别人的讨论说Alaska不能有intention所以排除了，我不怎么明白。 求老师解答

Newspaper editorial:
 
In an attempt to reduce the crime rate, the governor is getting tough on criminals and making prison conditions harsher.  Part of this effort has been to deny inmates the access they formerly had to college-level courses.  However, this action is clearly counter to the governor's ultimate goal, since after being released form prison, inmates who had taken such courses committed far fewer crimes overall than other inmates.
 
Which of the following is an assumption on which the argument depends?
请Tina老师解答一下，原文的逻辑链是说在监狱上过课程的人犯罪少，所以不让上课不能降低犯罪率。A选项说不上课就不能阻止人犯罪，这个逻辑上有什么问题？
