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.

A long-term study of some 1,000 physicians indicates that the more coffee these doctors drank, the more they had a likelihood of coronary disease.
又来提问麻烦老师了。。很简单一道题但选错了。。我选的C，看OG的解释说C的would have a likelihood to have is wordy, 不如D简洁。我理解C选项的结构是subject+verb + 宾语 + to + verb，这样表达语义我以为还挺清晰简单的，为什么不如D呢？ 总是挂在communication effectiveness上，很惆怅。求问老师，怎么判断两个选项之间哪个简洁有效呢？ 刚刚考了一次，买了ESR，ESR现在有SC的分项报告（分成grammar和communication effectiveness），我在grammar上都已经80%正确了，communication effectiveness只有25%，怎么办呢？谢谢

The inside of a rectangular carton is 48 centimeters long, 32 centimeters wide, and 15 centimeters high. The carton is filled to capacity with k identical cylindrical cans of fruit that stand upright in rows and columns, as indicated in the figure above. If the cans are 15 centimeters high, what is the value of k ?
(1)Each of the cans has a radius of 4 centimeters.
(2)Six of the cans fit exactly along the length of the carton.
老师请问，这道题目是默认以48 32为底面来放置易拉罐吗？因为如果放置底面不同会出现不同结果。要求有多少个易拉罐即k，那就求不出来呀。
