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.

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.

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.

Snowmaking machines work by spraying a mist that freezes immediately on contact with cold air. Because the sudden freezing kills bacteria, QuickFreeze is planning to market a wastewater purification system that works on the same principle. The process works only when temperatures are cold, however, so municipalities using it will still need to maintain a conventional system.

Which of the following, if true, provides the strongest grounds for a prediction that municipalities will buy QuickFreeze’s purification system despite the need to maintain a conventional purification system as well?

Escalating worldwide demand for corn has led to a sharp increase in the market price of corn, and corn prices are likely to remain high.  Corn is extensive used as feed for livestock, and because profit margins are tight in the livestock business, many farmers are expected to leave the business.  With fewer suppliers, meat prices will surely rise.  Nonetheless, observers expect an immediate short-term decrease in meat prices.
 
Which of the following, if true, most helps to justify the observers' expectation?

A significant number of complex repair jobs carried out by Ace Repairs have to be reworked under the company's warranty.  The reworked jobs are invariably satisfactory.  When initial repairs are inadequate, therefore, it is not because the mechanics lack competence; rather, there is clearly a level of focused concentration that complex repairs require that is elicited more reliably by rework jobs than by first-time jobs.

Which of the following most logically completes the passage?
 
Each species of moth has an optimal body temperature for effective flight, and when air temperatures fall much below that temperature, the moths typically have to remain inactive on vegetation for extended periods, leaving them highly vulnerable to predators.  In general, larger moths can fly faster than smaller ones and hence have a better chance of evading flying predators, but they also have higher optimal body temperatures, which explains why ______.
英老师之前说只有B和体温相关，可是我理不清逻辑。 最后一句话我的理解是：通常，大飞蛾可以飞得更快比小飞蛾，因此有更大机会躲开飞行的捕猎者，但是他们也有更高的理想体温，这个用来解释---- 对于这个but我不是很理解，不知道划线部分的内容应该support还是weaken

Which of the following most logically completes the passage?
 
Garnet and RenCo each provide health care for their employees.  Garnet pays for both testing of its employees' cholesterol levels and treatment of high cholesterol.  This policy saves Garnet money, since high cholesterol left untreated for many years leads to conditions that require very expensive treatment.  However, RenCo does not have the same financial incentive to adopt such a policy, because __________.
我觉得D是对的。 D选项说的是R公司的人不太可能得高胆固醇和G公司相比。因为不太可能得所以不用检查了，我觉得意思连得上。 而E说 employee在R公司呆的平均时长比G短。我认为与原文有一点关系但是没有特别大关系。 而且E说的是average length 。那就是总的时长除以人数得出的。比如说：如果G公司又一个人在此公司呆了两年。而R公司有三个人分别呆了两年零一天和两年零二天和一天。那average length 算下来是R短，可是呆了一天的人是不需要treatment的，可是呆了两年多的那两个人是需要treatment的。所以即使employee在R公司呆的平均时长比G短，可治疗R公司的人却更加expensive。 不知道哪里想错了，希望老师能解答一下。谢谢！

Editorial:
 
In Ledland, unemployed adults receive government assistance.  To reduce unemployment, the government proposes to supplement the income of those who accept jobs that pay less than government assistance, thus enabling employers to hire workers cheaply.  However, the supplement will not raise any worker's income above what government assistance would provide if he or she were not gainfully employed.  Therefore, unemployed people will have no financial incentive to accept jobs that would entitle them to the supplement.
 
Which of the following, if true about Ledland, most seriously weakens the argument of the editorial?
英老师说D选项是个不相干选项。而我认为这是一个support选项 可是我觉得D翻译为：那些每年不工作的人收到的政府资助比他们每年的工资要少。这将使得大家更加不工作。 而我们需要找出一个选项说政府的assistance是有用的促进大家工作。 请老师看一下我哪里理解错了

In the nation of Partoria, large trucks currently account for 6 percent of miles driven on Partoria's roads but are involved in 12 percent of all highway fatalities.  The very largest trucks—those with three trailers—had less than a third of the accident rate of single-and double-trailer trucks.  Clearly, therefore, one way for Partoria to reduce highway deaths would be to require shippers to increase their use of triple-trailer trucks.
