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.

Wateree, anchored in the harbor of Arica, off the coast of what is now northern Chile, rode on the crest of a tsunami (seismic sea wave) and coming to rest in the Atacama Desert, it was some three miles up the coast and almost two miles inland from its initial anchorage.

According to the passage, Krontiris’s work differs from that of the scholars mentioned in line 12 in which of the following ways?
我听了已有录音的还是不明白，我感觉也许是我对文章的逻辑理解有问题。我理解的这篇文章说的是，先引出JB和JK两个极端观点，然后说最近出现了一种趋势，就是学者们不同意这两人观点，因为这两人没考虑到那时女性不同的身份等各种不同，而就对上层的印第安女人做了研究就得出了结论。但是，这群学者自己也只是把重点放在中上层女性身上，（就是第二段第一句，这里的the trend 难道不是说的这群学者吗？）因为这群女性有文化会写东西blabla。举个例子，Tina 这个人就是，写来写去其实写的是有文化的女人blabla。 我理解的不对吗？很费解了

The results of the company's cost- cutting measures are evident in its profits, which increased five percent during the first three months of this year after it fell over the last two years.
老师您好！这道题我选的是e，做题的时候是这么想的：首先觉得with不如which结构对profits的修饰精准所以排除了de，然后因为ab中的it单复数不一致排除掉这两个选项，然后我看了一眼c，不知道after falling这是什么语法结构啊，觉得这结构不靠谱所以把c又给排除了。。。我又在de中选了e，因为没用到after falling这个用法。我就想请老师给我解释一下after falling这是语法里的什么用法啊！我很明确为啥选c了，但就是after falling这里搞不懂很难受啊！！

请教Tina老师这样一道题： The first detailed study of magpie attacks in Australia indicates that by the time they had reached adulthood, 98 percent of men and 75 percent of women born in the country have been attacked by the birds. A. by the time they had reached adulthood, 98 percent of men and 75 percent of women born in the country have been attacked by the birds B. by the time they reach adulthood, 98 percent of men and 75 percent of women, who were born in the country, had been attacked by the birds C. by the time they reached adulthood, 98 percent of men and 75 percent of women born in the country had been attacked by the birds D. 98 percent of men and 75 percent of women that were born in the country were attacked by the birds by the time they reach adulthood E. 98 percent of men and 75 percent of women who were born in the country, by the time they reached adulthood had been attacked by the birds 这道题答案是C，我错选了D。原因是因为C中离they最近的名词是男人和女人（magie attacks是袭击，magie感觉是修饰成分，而且还是单数），因此我觉得C太容易让人误认为they指代的是人而不是鸟了，D虽然繁杂一点，但是they可以很好地指代在鸟上，不会产生歧义，因此选了D，请老师解答，谢谢！

Correctly measuring the productivity of service workers is complex. Consider, for example, postal workers: they are often said to be more productive if more letters are delivered per postal worker. But is this really true? What if more letters are lost or delayed per worker at the same times that more are delivered?
The objection implied above to the productivity measure described is based on doubts about the truth of which of the following statements?
题目问的是反驳基于对哪些事实的疑问。文章条件是信件寄送更多的同时也丢了很多，所以不能说明更具生产力。根据相关性ABC都排除了。 选择了E，因为反对的观点中一直提的是信件的数量问题，寄送的数量与劳动生产力是相关的，该选项与文章观点直接对应。D选项服务质量在计算劳动生产力时可以忽视，没懂这个选项，如果可以忽视，那么那些丢失的信件也无所谓了，劳动生产力应该是提高了呀。 请老师帮忙解答下疑问
