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.

Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive.  Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600.  However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.
Which of the following is an assumption on which the argument depends?
请唐瑭老师解答一下：这道题我先看题干最后一句，我觉得重点是“收到program的Verdianders的数量没有上升”。 然后我看选项把与人无关的都干掉，干掉CE。接着ABD中，我认为A在讲，几乎没有station广播给之前没有RDS的人；B在讲Verdiader有没有equipped radio，D讲1996年的Verdiander不能收到1994年以后的广播， 我知道B无关，想问一下为什么A不对 E对 谢谢老师

A site once used as an observatory by the Anasazi, ancient pueblo dwellers of New Mexico, has been recently discovered where patterns of light and shadow were employed to establish the precise limits of the positions of the Sun and Moon over a nineteen-year cycle.
请问金老师，我听您说过，如果A选项的语义没有问题，那我们就不能随便去改掉她。我只读A时并没有发现语义和语法的错误，虽然确实后面几个选项语义也没问题，但为什么这时候要考虑去否定A的语义呢？

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 __________.
请唐瑭老师回答一下： 这道题我开始按您讲的方法只读了最后一句话，然后发现such a policy不知道是什么就往上找，看到倒数第二句this policy saves发现还是指代，没有讲具体policy的内容，就没有读这句，接着再往上找了一句（Garnet pays…）。把Garnet pays这句话读完之后，我发现讲的是Garnet为test 和treatment付钱的事情。然后我开始读选项，把AB排除后，我首先觉得CDE都不对，因为都没有讲钱的事情。之后我再对比看CDE的选项， C：R比G有更多员工； D：R比G员工level更高 E：R的员工在公司时间比G短 我认为C更好，因为员工人数多让R付的钱多，因此R 不愿意采取这个policy。DE我想不到跟不采取policy的关系 想问一下老师，我这样想为什么不对呢，谢谢

Professor Vasquez gave a quiz to two classes. Was the range of scores for the first class equal to the range of scores for the second class?
(1)   In each class, the number of students taking the quiz was 26, and the lowest score in each class was 70.
(2) In each class, the average (arithmetic mean) score on the quiz was 85.
请问老师，这道题C选项为什么不对呢？如果平均值是85，有一个最低值是70，那肯定有100分，是因为不知道总分数是多少所以选E吗？
