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.

Though the law will require emissions testing of all diesel vehicles, from
tractor trailers to excursion buses, it will have no effect on sport utility
vehicles, almost all of which are gasoline powered, and will not be sub-
jected to emissions-control standards as stringent as they are for
diesel-powered vehicles.
这题我想问个问题，希望老师不要打我…almost all of which are gasoline powered 这句话不是个主谓宾完整的句子吗，这句子不是没加连词嘛…为什么可以这么写啊，正常情况不是应该用个不完整的句子来表示修饰前句的vehicles嘛？然后假设我接受了前句确实应该有are，那正确选项里subject如果作为动词的话和and前平行不是应该是don’t subject to，如果作为形容词为什么不加 are 和and前的are平行啊…完全看懵了

The English physician Edward Jenner found that if experimental subjects were deliberately infected with cowpox, which caused only a mild illness, they are immune from smallpox.
如何判断which cause和 causing的修饰对象分别是谁？我觉得which cause修饰的是前面整个，但是tina老师上课说gmat里非限制性定语从句不存在。我觉得causing修饰的是cowpox，因为就近修饰原则。我想请问一下我的思路错在哪里？

Bluegrass musician Bill Monroe, whose repertory, views on musical collaboration, and vocal style were influential on generations of bluegrass artists, was also an inspiration to many musicians, that included Elvis Presley and Jerry Garcia, whose music differed significantly from his own.
恳请王文静老师帮助理解下这道题。 请问A选项为什么不对呢？觉得A选项相比B，更清楚地表明了BM和他的三个优点哪个是influence的发起者，哪个是inspire的发起者。 我的问题是: 1.上述的我对A和B的处理方法在语法题中可用吗？ 2.不选A而选B，是因为A的表达太冗长了吗？ 求教。

Most of Portugal's 250,000 university students boycotted classes in a one-day strike to protest a law that requires them to contribute $330 a year toward the cost of higher education, previously paying $7 per year.
求问tina老师，我听了您比较新的一个解答说a选项中的逗号ing的发出者应该是前面的laws，是不是说逗号ing形式的发出者既可以是前句的整句话，也可以是前句主语，也可以是前句从句的主语，和前句从句的整句话呀，可是我又产生了一个疑惑，我之前问过一道题 Among lower-paid workers, union members are less likely than nonunion members to be enrolled in lower-end insurance plans imposing stricter limits on medical services and requiring doctors to see more patients, and spend less time with each. Options: imposing stricter limits on medical services and requiring doctors to see more patients, and spend imposing stricter limits on medical services, requiring doctors to see more patients, and spending that impose stricter limits on medical services, require doctors to see more patients, and spend that impose stricter limits on medical services and require doctors to see more patients, spending that impose stricter limits on medical services, requiring doctors to see more patients and spending Correct: D 这道题D选项的spending的发起者是前句从句里的医生吗？可是医生不是从句里的主语呀。对逗号ing充满了疑惑。谢谢美丽的Tina老师！

恳请王文静老师帮忙解释下这道题。 请问D为什么不对呢？bring的动作发出者是前面这件事。A选项有两种理解方式，一种是sea eagles发出了bring的动作，一种是这件事发出了bring的动作。而D中的it明显指代的是前面这件事，所以不会造成歧义。所以我选了D。 求教。

In an experiment, each volunteer was allowed to choose between an easy task and a hard task and was told that another volunteer would do the other task. Each volunteer could also choose to have a computer assign the two tasks randomly. Most volunteers chose the easy task for themselves and under questioning later said they had acted fairly. But when the scenario was described to another group of volunteers, almost all said choosing the easy task would be unfair. This shows that most people apply weaker moral standards to themselves than to others.

Which of the following is an assumption required by this argument?

Though being tiny, blind, and translucent, a recently discovered species of catfish lessens their vulnerability with thickened bones and armor plates on their sides.

求问老师，为什么B是对的呢？ 我一上来就杀掉了B，因为看到that lessen its vulnerability前面是sides，修饰对象不对，是说它跳跃修饰了吗？？？考场上如何判断它是就近修饰还是跳跃修饰呢？
