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.

Some scientists contend that many species of dinosaur had a metabolism more like a warm-blooded mammal's than a cold-blooded reptile's.
先是我回忆自己的做题过程： 首先排除B，主谓不一致 扫到BCE发现比A多了that、those of 根据题意 把A也排除了 觉得DE比较像 先开比 发现可能是修饰中心不一样 D是dinosaur有m，E是species有m，但m不认识，所以不好说，就先看C，感觉它和DE的区别在于想说的事不太一样，C是m像…. 而DE则是存在一些恐龙种类其m与谁谁的像，而句子想说的应该是m像而非是否存在恐龙什么，所以选了C 然后是老师的： 先读完A，发现A没明显错，然后一溜，发现ABC/DE 格局，而觉得DE明显没有ABC看着爽，先排除DE，然后ABC开比，发现C明显脱了裤子放屁，B么动词发起者不一致，所以选A 然后我分析了下，主要歧义就是出在C这个选项是否是属于废话型的，因为我做的时候看到more than 就马上觉得这里存在一致性，那么不是应该加上that of更好么？因为好像恍惚记得上课有听到过说语意的精确性，就是连说出某人的也不够，一定要说出某人的什么

According to the passage, the historians mentioned in the highlighted text and the scholars mentioned in the highlighted text disagree about the
这篇文章几乎没读懂，此题我的定位是在第一段“”highlights处后面的两句 passage: “Some historians” contend that conditions in the United States during the Second World War gave rise to a dynamic wartime alliance between trade unions and the African American community, an alliance that advanced the cause of civil rights. They conclude that the postwar demise of this vital alliance constituted a lost opportunity for the civil rights movement that followed the war. “Other scholars”, however, have portrayed organized labor as defending all along the relatively privileged position of White workers relative to African American workers. Clearly, these two perspectives are not easily reconcilable, but the historical reality is not reducible to one or the other. Unions faced a choice between either maintaining the prewar status quo or promoting a more inclusive approach that sought for all members the right to participate in the internal affairs of unions, access to skilledand high-paying positions within the occupational hierarchy, and protection against management's arbitrary authority in the workplace. While union representatives often voiced this inclusive ideal, in practice unions far more often favored entrenched interests. The accelerating develop ment of the civil rights movement following the Second World War exacerbated the unions' dilemma, forcing trade unionists to confront contradictions in their own practices. According to the passage, the historians mentioned in the highlighted text and the scholars mentioned in the highlighted text disagree about the A.contribution made by organized labor to the war effort during the Second World War B.issues that union members considered most important during the Second World War C.relationship between unions and African Americans during the Second World War D.effect of the Second World War on the influence of unions in the workplace E.extent to which African Americans benefited from social and political changes following the Second World War

Which of the following, if true, most logically completes the passage?
 
A recent poll found that over 80 percent of the residents of Nalmed Province favored a massive expansion of the commuter rail system as a means of significantly easing congestion on the province's highways and were willing to help pay for the expansion through an increase in their taxes.  Nevertheless, the poll results indicate that expansion of the rail system, if successfully completed, would be unlikely to achieve its goal of easing congestion, because _______.
读原文：poll中显示80%居民支持扩大铁路来作为解决highway拥挤的办法并且愿意付更多的税款，然而poll结果表明如果扩大实施，也不太可能实现缓解拥堵的目标，是因为___ 由于是句子填空题，而且问的是原因，我就主要关注了之前的一句话 对选项A和E有疑问 我读成： A 这些人觉得缓解交通有好处，就是支持扩大铁路的原因，我不知道为什么沾，而且就算沾，我觉得也并不能解释现象，反而像是驳斥的 E 有人会去乘rail 虽然我觉得它也含有驳斥意味，但怎么样觉得和前提有点沾 犹豫了半天，选了E
