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.
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.

Delta Products Inc. has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity. The question has been raised whether it can be concluded that for a given level of output Delta’s operation now causes less fossil fuel to be consumed than it did formerly. The answer, clearly, is yes, since the amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount needed to power the older technologies, provided level of output is held constant.

In the argument given, the two boldfaced portions play which of the following roles?

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?
我纠结ae 逻辑链-新药3天疗程即可康复(旧药需要7天治疗) 所以，用新药可以减少复发概率(假设病人服药习惯不变) A我脑补了假设a成立，可以推测新旧俩类药的某些成分相同，也许这些相同成分很关键用于治疗strep ;很不明显的支持premise新药有用。尽管听了解答都说这是out of scope... E我感觉重复说 并没有起到支持 病人feel和实际好是有区别的，文章提到的reinfection 就是一个证据(尽管原文没有提到stop taking drugs within 3 days 的原因，我脑补 从常识角度来说，病人觉得身体恢复了 所以不用吃药了)。选项说了不管新旧俩类药，病人用了都感觉变好了。如果说要体现增强文章，先有一个前提-如果病人feel not fully recovered,他们实际病肯定没有好，他们会继续吃药。这样反推了新药让病人feel fully recovered，说明至少新药和旧药都能让人感觉病好了，感觉药起作用了。那这样也是微小支持。 老师都说abcd无关 只有e才有关。这道题我模考花了2分15秒。老师是否可以通过我的角度 在考场中 如何判断选项。从有关无关 我觉得a有关。尽管搜了网上基本没有人这么考虑。。

Beginning in 1966 all new cars sold in Morodia were required to have safety belts and power steering. Previously, most cars in Morodia were without these features. Safety belts help to prevent injuries in collisions, and power steering helps to avoid collisions in the first place. But even though in 1966 one-seventh of the cars in Morodia were replaced with new cars, the number of car collisions and collision-related injuries did not decline.

Which of the following, if true about Morodia, most helps to explain why the number of collisions and collision-related injuries in Morodia failed to decline in 1966?

Chaco Canyon, a settlement of the ancient Anasazi culture in North America, had massive buildings. It must have been a major Anasazi center. Analysis of wood samples shows that some of the timber for the buildings came from the Chuska and San Mateo mountains, 50 miles from Chaco Canyon. Only a major cultural center would have the organizational power to import timber from 50 miles away.
