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

There is a widespread belief in the United States and Western Europe that young people have a smaller commitment to work and a career than their parents and grandparents and that the source of the change lies in the collapse of the "work ethic."
这道题比较的是现代年轻人拥有更少的“责任感”和“承诺”，强调的应该是名词commitment更少，为什么不可以用that of 来对比，一定要补充had呢

Unlike frogs that metamorphose from tadpoles into adults within a one-year period, it takes three to four years for the mountain yellow-legged frog of the Sierra Nevada to reach adulthood, and so they are restricted to deeper bodies of water that do not dry up in summer or freeze solid in winter.
请问老师这个题的c选项，因为加了 in the Sierra Nevada,mountain yellow-legged tree frogs就不能和unlike后面的东西对应了吗？还有E里面and 后面的they为什么要重复出来一次 我觉得很多余啊

最后留了ADE 觉得now部分应该作为结果伴随，排除A，在DE中选，因为about离knowledge越近越好，选了E 我想问问老师，1.这种ADE最后只有结构上的不同时，是由于句意重心导致选A的吗，着重强调现在有conclusion而非过去的研究；2.DE之间的对比，E把over 20年放中间来使得about。。离knowledge近是比D更好的吗。

Growing evidence that coastal erosion occurs continuously, not in just such calamitous bursts like hurricanes, has led scientists and planners to urge a stringent new approach to limiting development along the nation's shoreline.
这个题首先举例用such as ，因此like排除(A,C,E)，之后是不是因为D句子残缺，growing evidence缺谓语来排除呢。至于之前有个老师讲just 修饰谁的原因，只在哪里，在只哪里，貌似挺难理解。

A group of paleontologists recently announced that a site in Utah has yielded fossils of some of the biggest armored dinosaurs ever found, and that they were at least 25 million years older than any similar dinosaur type previously found in North America.
其实这道题我觉得没有答案，如果答案是D，但是这里D前面不加and不就是双主语了吗，这算是犯了宏观错误吧？

The budget for education reflects the administration's demand that the money is controlled by local school districts, but it can only be spent on teachers, not on books, computers, or other materials or activities.
老师我听了您的讲解，还有个地方不太清楚，您说因为but前面没有that，所以it不和从句并列，而是和主句。但我做题的选的A选项，是因为想到tina老师上课讲过but连接两个句子的时候，不要求句子形式长得完全一样，所以我觉得这个题中but链接的两个句子可以是前句从句和but it can only be spent on......所以想问下老师，不要求句子形式完全一样是啥意思呢？为什么不能用在这个题A选项里的主句和but后的句子呢？

It can be inferred from the passage that which of the following would most probably be one major difference in behavior between Manager X, who uses intuition to reach decisions, and Manager Y, who uses only formal decision analysis?
这道题目错选了B选项，题目问直觉管理者和正式决策分析管理者之间的区别。文章第一段说明了古典理性模型和直觉判断是什么，第二段阐述了对直觉判断理解的现状，第三段给了五种直觉判断的方式。第四段对高管人员的直觉管理中的一种进行详细阐述。 因此出现两者对比的很可能是第三段，定位到了Most senior executives are familiar with…… 选出了B。 答案的C选项是怎么推断出来的，我的定位是错了吗？ 请老师指明下方向
