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.

47．问 13个数的中位数 是否得20？ 条件1 6 numbers are less than or equal 20 条件2 6 numbers are more than or equal 20. 6.唯一有个题没找到思路，蒙的。5的K次方是大约是从99到199中的奇数的乘积，包括两端，求K（答案有13，15，20之类的）想了半天没搞出来（可能理解有误，大家不要纠结。。。）某位筒子的答案是13 7.ABCDEF六个人坐一张桌子，问A和FB相邻,B和AC相邻,C和BD相邻,D和CE相邻,E和DF相邻,F和EA相邻的概率这题没思路啊排列组合太差了怎么办啊 55.抛物线，y=(x+2)^2+1， 抛物线上一点（a，b） 问如下哪一个不对 答案是诸如a>0, b>0 a<0, b>0 这样的东西 其实就是考察的，抛物线在y轴右边部分单调增，且节距大于0，于是X>0的时候Y>0 60. DS：告诉一个正整数，它恰好有6个因数，问这个数是多少 1. 6个因数中有两个是质数 2。这个数小于15。 我选B。 符合1的数不唯一，如12,28； 符合2的只有12。

The investigations of many psychologists and anthropologists support the generalization of there being little that is a significant difference in the underlying mental processes manifested by people from different cultures.
思路是这样的，剩下D和B。D中虽然making有些别扭，但是没有能杀掉他的具体名目；B中makes和前面的时态不和，所以去掉了（后来想法律要是到现在都还生效，也可以用makes，但是当时没想出来） 所以用make比较，大概不能区分B和D了 而且BD中等其他部分（如for。。。to do和that。。。that）希望老师讲讲感觉，以作积累

Driving the steep road to the mountaintop Inca ruins of Machu Picchu is potentially dangerous and hiking there is difficult.  Now the Peruvian government is installing a cable car that will make access much easier, and hence result in a large increase in tourism.  However, since the presence of large numbers of tourists tends to accelerate the deterioration of a site, installation of the cable car is certain to result in harm to the ruins.
