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.

Heavy commitment by an executive to a course of action, especially if it has worked well in the past, makes it likely to miss signs of incipient trouble or misinterpret them when they do appear.
错选C，在英老师每日一题的分析里看到C选项的错误是especially和if一个表递进一个表条件，不能同时出现，是这个原因么？另外，有讨论帖说C中it指代不明，但只有在代替course of action时语义才通顺，为什么会认为有可能指代incipient trouble呢？

错选D,介词by和with是判断关键么？还是growing这种V-ing分词做修饰不能与其他插入语以逗号形式相连出现呢?

Some anthropologists believe that the genetic homogeneity evident in the world's people is the result of a "population bottleneck"—at some time in the past our ancestors suffered an event, greatly reducing their numbers and thus our genetic variation.
错选D。不知道怎么判断出需要保留that和at呢？我把D选项理解成some time in the past（when省略） our ancestors...所以刚开始就把ABC三个有介词的选项直接排除了。

Ryūnosuke Akutagawa's knowledge of the literatures of Europe, China, and that of Japan were instrumental in his development as a writer, informing his literary style as much as the content of his fiction.
错选答案D。解析里面说as much as会有歧义，但如果the content 也理解为 inform style的动作发出者那不是非划线部分要写成did the content of his fiction或the content of his fiction did吗？（所以我认为不存在理解上的歧义）另外，一般是说要根据A选项来确定句意和句子重心吧，所以我选择保留as much as了。

Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were last year.
不太清楚平行结构哪些部分可以省略。觉得A选项price比较那儿可能有歧义即price和last（year) 比，为什么不是prices are expected to be higher this year than those of last year或者 than they were last year？（以前看过一个选项类似price in last year is higher than now被判为错误了）

Possible long-term consequences of the "greenhouse effect," the gradual warming of the Earth's climate, may include melting the polar ice caps and a rising sea level.
之前的答疑录音中老师说rising sea level、changing temperature都不对，必须加in。但实际上是不是应该分情况？如果rise做动词用，就不需要加in？比如这个题的A选项改为 may include melting the polar ice caps and rising sea level就正确了？

Discussion of greenhouse effects have usually had as a focus the possibility of Earth growing warmer and to what extent it might, but climatologists have indicated all along that precipitation, storminess, and temperature extremes are likely to have the greatest impact on people.
这个题我用排除做出来选C，但是不是很明白C选项whether Earth would grow warmer and to what extent，这个地方为什么是parallel的， 希望老师讲一下C和D选项的whether.....and......这个部分parallel的问题。谢谢老师

The art jury will select either Fillmore’s or Clivestone’s sculptures, but not both, for the midwest art show to be held next spring. If Fillmore’s sculptures are chosen, then the show will contain bronze works. If Clivestone’s sculptures are selected, the show will contain sculptures made from stainless steel.
Assuming the statements in the passage are true, which one of the following statements must also be true?
我选了E，请问老师原文指出如果有Fillmore，则会出现bronze，如果有Clivestone，则会出现stainless steel的作品。那么选项指出，如果展品没有铜或不锈钢的雕塑，则肯定不会有F和C的作品。这个为什么不选呢，我看很多同学都有疑惑，但并未找到讲解录音。谢谢！
