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.

The violent crime rate (number of violent crimes per 1,000 residents) in Meadowbrook is 60 percent higher now than it was four years ago.  The corresponding increase for Parkdale is only 10 percent.  These figures support the conclusion that residents of Meadowbrook are more likely to become victims of violent crime than are residents of Parkdale.
 
The argument above is flawed because it fails to take into account
选的a m的犯罪率比十年前高了60%而p只高了10％，说明m的居民更容易犯罪 选a，我觉得如果人口密度m这几年大幅下降的话，虽然犯罪人数比例高了单实际犯罪人数不一定增加了，因此就无法得出本文结论 求老师解答

Although Alice Walker published a number of essays, poetry collections, and stories during the 1970s, her third novel, The Color Purple, which was published in 1982, brought her the widest acclaim in that it won both the National Book Award as well as the Pulitzer Prize.
思路，B选项 bringing的发起者是“her third novel”,后面由“by”连接winning both。。and。。感觉可以， 排除选项C的思路：“brought”与前一句有句子连用之嫌，且后面的winning也没有连词与之相连，故杀。

Unlike the original National Museum of Science and Technology in Italy, where the models are encased in glass or operated only by staff members, the Virtual Leonardo Project, an online version of the museum, encourages visitors to “touch” each exhibit, which thereby activates the animated functions of the piece.
思路：误选A，认为“游客touch exhibit”这个行为可以activate 功能。 而选项D给的感觉是touch 和 activate 并列，游客直接activate功能，虽然A和D都有时间上的先后（thereby）， 但是感觉上还是A更好一点。这么想错在哪里呢？

Over the next few years, increasing demands on the Chattahoochee River, which flows into the Apalachicola River, could alter the saline content of Apalachicola Bay, which would rob the oysters there of their flavor, and to make them decrease in size, less distinctive, and less in demand.
根据选项可以选择出D这个选项，但是D选项的robbing不是很理解，robbing的发起者到底是 “increasing demands on the Chattahoochee River” 还是“which flows into the Apalachicola River”所导致的robbing呢？ 麻烦老师帮忙解答一下，谢谢~
