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.

Historian:  In the Drindian Empire, censuses were conducted annually to determine the population of each village.  Village census records for the last half of the 1600's are remarkably complete.  This very completeness makes one point stand out; in five different years, villages overwhelmingly reported significant population declines.  Tellingly, each of those five years immediately followed an increase in a certain Drindian tax.  This tax, which was assessed on villages, was computed by the central government using the annual census figures.  Obviously, whenever the tax went up, villages had an especially powerful economic incentive to minimize the number of people they recorded; and concealing the size of a village's population from government census takers would have been easy.  Therefore, it is reasonable to think that the reported declines did not happen.
 
In the historian's argument, the two portions in boldface play which of the following roles?

Citing the recent increase in earnings by several computer companies, economists feel that a cycle has begun in which personal computer users, especially corporate consumers, are replacing their PC's with more powerful models.
AB读一遍觉得没什么问题先留着，CD的there is和it is在这里都是比较多余的所以排除，E整个就一塌糊涂，排除。 纠结AB时错选了B 划线后面, especially corporate consumers是前面 computer users的同位语，B选项中也就是they的同位语， 想问老师，选A是因为这个同位语要跟着它所指的users更好吗，they的话还要对应到前面users才行所以相比而言差了一些吗？谢谢

Information in the passage suggests which of the following concerning the Earth's mantle 2.5 to 4 billion years ago?
文章没太读明白，好像是在说一块火山石的发现改变了科学家的假设。半蒙的，不知道这个定位对不对，请老师指点~ 问题问2.5 to 4 billion years ago地幔怎么了，由这个数字定位到最后一句话，从by1960开始读的，说以前这种说法是普遍认可的就是火山石有如此高的magnesium是不存在的，因此这个发现改变了地质学家的假设关于地幔。 那地质学家的假设是什么呢？第一段第二句在讲，好像主要提到了magnesium和high temperature所起的作用，所以排除了其他，选了D。

Political advocacy groups have begun to use information services to disseminate information that is then accessed by the public via personal computer.  Since many groups are thus able to bypass traditional news sources, whose reporting is selective, and to present their political views directly to the public, information services present a more balanced picture of the complexities of political issues than any traditional news source presents.
