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.

An overwhelming proportion of the most productive employees at SaleCo's regional offices work not eight hours a day, five days a week, as do other SaleCo employees, but rather ten hours a day, four days a week, with Friday off.  Noting this phenomenon, SaleCo's president plans to increase overall productivity by keeping the offices closed on Fridays and having all employees work the same schedule—ten hours a day, four days a week.
 
Which of the following, if true, provides the most reason to doubt that the president's plan, if implemented, will achieve its stated purpose?

这题好恶心：1. more and more littering occured 和 become more and more littered 我该怎么用中文提示自己他们的区别呢？曼哈顿上面说一个表示程度，一个表示频率。2. because 和 because of 一个更深层次的区别是前者直接表明了因果关系，而后者 of 后面的名词只是一个引出结果的subject，并不能真正的表示造成结果的原因？谢谢！

Fossils of a whale that beached on an African shore more than a million years ago and was subsequently butchered by hominids have been recovered by paleontologists.

对于这题，有如下几个疑问。 第一，如何判断“that”指代的是“fossils”还是“whale” 第二，在做gmat语法题的时候，定语从句后的平行，有时候是会把that都带上。比如说“that beached on an African...that was subsequently”，出现两个定语从句的平行。而本题是beached和was butchered平行。这2者分别有什么意义和区别？ 错选的是e，看了答案后觉得a很顺，但依然有如上2个问题。

The passage suggests which of the following about the claim that a firm will become more efficient and competitive by downsizing?
本题C选项为何错呢，原文第一段最后一句有说Thus, organization theory cannot adequately explain downsizing; non-economic factors must also be considered. ；另外，原文对问题所问的claim应该是正态度吧，毕竟第二段有说downsizing is now viewed as a signal that firms are serious about competing in the global marketplace

Starfish, with anywhere from five to eight arms, have a strong regenerative ability, and if one arm is lost it quickly replaces it, sometimes by the animal overcompensating and growing an extra one or two.
请教tina老师～ 错选E，之前听过什么主从句主语对应指代所以就先看了DE，因为前面说starfish xxx后面and 也是starfish xxx比较好（这个是不是不用？） 想借由这个题请教一下代词指代的问题，一般我们在看到代词的时候是就近找离其最近的名词去代入看语义合理否, 不合理的话再往前面的名词一个个找 OR就从句子的主语/开始的第一个名词开始往下找看有无合理名词指代, 往下找的越少就越清晰 反之则是指代不明. 第二种情况的话如果代词在从句里请问是从从句（即离其最近的句子）主语/名词开始找还是从主句主语/名词开始找？ 多谢老师解答🙏

Kate:  The recent decline in numbers of the Tennessee warbler, a North American songbird that migrates each fall to coffee plantations in South America, is due to the elimination of the dense tree cover that formerly was a feature of most South American coffee plantations.

Scott:  The population of the spruce budworm, the warbler's favorite prey in North America, has been dropping.  This is a more likely explanation of the warbler's decline.

Which of the following, if true, most seriously calls Scott's hypothesis into question?

请问D选项为何是不对呢？warbler迁徙到别的地方导致其数量减少不就是作为它因削弱了Scott给出的因为食物减少的原因了吧

The Testament of William Thorpe was published around 1530 as an appendix to Thorpe’s longer Examination. Many scholars, however, doubt the attribution of the Testament to Thorpe because, whereas the Examination is dated 1406, the Testament is dated 1460. One scholar has recently argued that the 1460 date be amended to 1409, based on the observation that when these numbers are expressed as Roman numerals, MCCCCLX and MCCCCIX, it becomes easy to see how the dates might have become confused through scribal error.

Which of the following, if true, would most support the scholar’s hypothesis concerning the date of the Testament?

The traditional treatment of strep infections has been a seven-day course of antibiotics, either penicillin or erythromycin.  However, since many patients stop taking those drugs within three days, reinfection is common in cases where those drugs are prescribed.  A new antibiotic requires only a three-day course of treatment.  Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed.
 
Which of the following, if true, most strengthens the argument?
排除无关选项A，B，D，剩下C和E；好像唐瑭老师说只看逻辑题最后一句？E选项说“无论新药还是老药”与原文逻辑最后一句（问题所问）的where the new antibiotic is prescribed 冲突，故选了C
