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.

这道题中的round to是什么意思？我可不可以理解为round to是一个波动幅度，这里以290miles为中心左右各波动5miles形成285和295。那么12加仑这里round to the nearest gallon也没有说波动幅度是多少为什么就知道幅度是1呢？

原文说的是产量减少了但是利润能增加。A说的是成本，很多题目里面说要提高利润，如果选项中只提到了成本基本都不对。所以选了D，种的更多了可以卖的更多。

Since 1990 the percentage of bacterial sinus infections in Aqadestan that are resistant to the antibiotic perxicillin has increased substantially. Bacteria can quickly develop resistance to an antibiotic when it is prescribed indiscriminately or when patients fail to take it as prescribed. Since perxicillin has not been indiscriminately prescribed, health officials hypothesize that the increase in perxicillin-resistant sinus infections is largely due to patients' failure to take this medication as prescribed.

Which of the following, if true of Aqadestan, provides most support for the health officials' hypothesis?

请教胡凡老师，D选项确实可以说明没有做到take this medication as prescribed。但是原文说的是 the increase in perxicillin-resistant sinus infections is largely due to patients’ failure to take this medication as prescribed.题目说的是因为病人没有按照医生的医嘱吃药，才导致细菌耐药。那应该是说吃多了这种药才会出现耐药性啊。。。。。。那么增加耐药性和病人少吃药怎么能联系上？病人因为有严重的副作用所以不继续服药，为什么会导致细菌耐药

Which of the following most logically completes the passage?

According to the last pre-election poll in Whippleton, most voters believe that the three problems government needs to address, in order of importance, are pollution, crime, and unemployment. Yet in the election, candidates from parties perceived as strongly against pollution were defeated, while those elected were all from parties with a history of opposing legislation designed to reduce pollution. These results should not be taken to indicate that the poll was inaccurate, however, since __________.
老师好！请问这种题是什么题型？感觉好像并不是演绎题中的任何一种？这题我凭感觉做的，在A和C之间犹豫，最后选的C，因为觉得原文中之说voters认为最应该address的问题里有pollution，但也没有说怎么address。觉得D不对是因为觉得D只提到了voters关心的三点中的两点。既然有一点（pollution）不accurate，不就代表这个poll是inaccurate的吗？请老师指出我思维里的问题，谢谢！

A manufacturer makes and sells 2 products, P and Q. The revenue from the sale of each unit of P is $20.00 and the revenue from the sale of each unit of Q is $17.00. Last year the manufacturer sold twice as many units of Q as P. What was the manufacturer’s average (arithmetic mean) revenue per unit sold of these 2 products last year?
我想问一下这里的：the manufacturer sold twice as many units of Q as P到底说的是Q是P的两倍还是P是Q的两倍？谢谢

A major chemical spill occurred five years ago at Baker's Beach, the world's sole nesting ground for Merrick sea turtles, and prevented nearly all the eggs laid that year from hatching.  Yet the number of adult female Merricks returning to lay their eggs at Baker's Beach has actually increased somewhat since five years ago.  Clearly, environmentalists' prediction that the world's Merrick population would decline as a result of the spill has proven unfounded.
 
Which of the following, if true, most seriously undermines the argument offered in refutation of the environmentalists' prediction?

NorthAir charges low fares for its economy-class seats, but it provides very cramped seating and few amenities. Market research shows that economy passengers would willingly pay more for wider seating and better service, and additional revenue provided by these higher ticket prices would more than cover the additional cost of providing these amenities. Even though NorthAir is searching for ways to improve its profitability, it has decided not to make these improvements.

Which of the following, if true, would most help to explain NorthAir’s decision in light of its objectives?
老师好！这道题我选了D。首先我排除了C，然后我排除了E，最后在ABD中徘徊，因为我觉得这三个选项都可以说明即使NorthAir什么也不做，收入也不会被影响，且D感觉更切题。我排除E的原因是觉得E提到了商务舱，而飞机有商务舱这件事是属于背景知识，原文中并没有提到，飞机可能根本没有商务舱。请问老师我以上思考问题的方式有哪些问题？谢谢老师！
