like只能表示类似，而such as是指包含关系的像，是一种列举。删除B、E。此外，前后应平行，删除D。C和A比较，C比较wordy，故而选A

为什呢不是果因推理？？
前提是果，用bill的给钱多
结论是因，因为credit cardlogo让顾客觉得自己钱多

题目中包含一个假设：如果有trading goods，就一定会被发现。b项刚好强调了这个假设。c项中的the first比较无关，而且as much as possible仍然包含被损坏的可能。

When rate means a price charged, it is followed by
the preposition for.

这题其实还是感觉smaller比decrease in size与后面less的平行更好

each是指each style of cooking,后接单数。A、B项的代词指代含糊不清，虽然我们知道B中的its是指India's，但GMAT一般不这么用

E 起码也得用下fingding that 嘛

by Ron:
The easiest way to eliminate D is to notice "that of...", which stands for... well, nothing. Nothing at all. It's not even possible to invent a noun that would make sense here.

("View ___ to be ___" is also wrong. Not idiomatic.)

老师C，E的paths有问题吗？前面是their 为什么要用单数呢？

看错了

老师这道题og里的答案好像是B

发现无法删除自己的问题。想明白了。即便simply 修饰random，也不能解释为简单随机，比如简单随机抽样是simple random sampling。所以simply random本身就是不对的。所以只能是but simply are

其实D选项里，是不是but simply are更好些？这样可以避免ambiguous （关于simply是修饰are还是ramdom）。

c和d选项解释下区别吧？我想着用being是表示客观事实吧？ 还有after后面的是不是用被动和主动都是可以的啊？

这道题现在看真的还挺简单的，但是当时做被生词困住了：
B balls肯定后面动词复数形式，错；
C 动词复数形式，错
D 动词复数形式， 错
E the finding 后面动词应该是单数形式， 错
所以选A
不知道算不算一种解题方法？

In this case, the phrase "each other" is clearly incorrect. It is used when only two entities are involved and are performing a reciprocal action. In this case, we know that there are a large number of tribes involved. With this information, we can eliminate choices (A) and (D).

"in return for"=in exchange for" ，""as a return on." =a gain or return on an investment of some sort

C: Newspaper had lower circulation in six months than (newspaper had) in a similar period a year earlier. 平行

D: Newspaper had lower circulation in six months than that (circulation) in a similar period a year earlier. 不平行

d应该是than they had in a similar period

我想多了。选了C，以为20世纪演员训练方法和18世纪的差不多，然后文中的那个演员又模仿了20世纪的某个人，也就是文中演员模仿了18世纪的方法。。。有什么不对么

难题都是取反!
