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

请问Tina老师，CDE的排除能不能是因为they前面有starfish与arms两个复数，they通常是就近指代，所以CDE中的they用的不好？感觉老师说的the animal与they冲突有点牵强，因为starfish本身是复数，在B选项中也与the animal单数冲突了，不知道我这么觉得对不对？

In addition to having more protein -than wheat does, the protein in rice is higher quality than that in wheat, with more of the amino acids essential to the human diet.
想请教王文静老师，这道题我比较纠结E选项。E选项不可以是rice和wheat的主语比较吗（比如您上课的例子I have more apples than Eric）？另外，B选项中，前面是用rice做主语的句子，后面是in wheat，变成介词加宾语了，感觉不太对应，这属于哪一种比较呢？谢谢！

In California today, Hispanics under the age of eighteen account for more than 43 percent, compared with a decade ago, when it was about 35 percent.
请教王文静老师关于比较的问题。我做题时第一步看比较，认为五个选项在比较上都是正确的。请教两个问题：听您的录播课，说是A选项中，前面没有东西可以跟一个时间 a decade ago 比，我当时觉得today可以和它相比较（状语比较？），您怎么看？2. 您说介词后面必须加宾语（compared with/to的后面），那么ABD在这一点上，是否都是错的？

While digging in the Egyptian desert, huge fossil bones have been found by paleontologists, which appears to have been the second most massive dinosaur that ever lived.
请教Tina老师，本题中的appear的动作发出者不应该是huge fossil bones，那为什么appear是单数，不是复数呢？是因为what有特殊性吗？谢谢老师

Charles Lindbergh, for his attempt at a solo transatlantic flight, was very reluctant to have any extra weight on his plane, he therefore refused to carry even a pound of mail, despite being offered $1,000 to do so.
请教Tina老师！我的思路是：主语重复排A（CL与he中间没连词） 词义重复排C（since，so）无因果关系排BE 结果选了D。D我感觉虽然繁杂，但是其保留了因果关系啊，E却将句子中的因果关系忽略了。。希望老师指点，谢谢！

With the patience of its customers and with its network strained to the breaking point, the on-line service company announced a series of new initiatives trying to relieve the congestion that has led to at least four class-action lawsuits and thousands of complaints from frustrated customers.
老师我还是不太懂，A选项里面的with并列为什么不对？语法题里面我不太会分析with的作用和成分。然后老师，trying to do的主语是跟that try to do 一样，都是new initiatives吗？

Marconi's conception of the radio was as a substitute for the telephone, a tool for private conversation; instead, it is precisely the opposite, a tool for communicating with a large, public audience.
老师为什么AB的a tool 是修饰telephone的？是因为插入语就近修饰？不可以修饰逻辑主语吗？然后E选项为什么不对呢，您可以详细点讲吗？
