题目分析：
本题主要考查了关于“平行”和“核心词”两个方面的问题。
选项分析：
A选项：both…and…是平行触发语，需要保证其连接两者在语法上和逻辑上要严格平行。真正平行的两者是这个公司挣的钱表明了两件事情：一是他们重新改革bottling system成功；二是低利率把一些跨国公司或者多国运营的公司的利润给放低的程度。因此，真正平行两者是“成功”和“程度”，即，both the success and extent。
B选项：Correct. 本选项在语法和逻辑上均是正确的。
C选项：本选项在平行处没有问题，但the extent定语部分的核心词有误。改定语部分是介词短语of poor currency exchange rates keeping down profits for multinational companies，其核心词为poor currency exchange rates。在逻辑上，“程度”应是降低的程度，而不是汇率本身的程度（汇率没有程度，只有汇率升高或降低的程度）。 因此，本题中extent必须用定语从句来修饰。
D选项：both…and…连接两者不平行。
E选项：平行错误同选项(D)。
c the extent of poor currency exchange rates （keeping...）是错的。因为keeping只是一个修饰语，所以导致extent of rates，语义错误。
Ron：
first off, the construction (preposition) + NOUN + VERBing is WRONG, unless the preposition refers directly to the NOUN. (that isn't usually the case, so, if you're in doubt, you should strike choices with this sort of construction.)
both and排除ADE，
C，extent of poor currency exchange rates，汇率的程度，这在表达上是有问题的，排除
B correct
注意！ both 擺放的位置有意思解讀的差異！
A : reflect the success of both …. and the extent to which.. 錯誤，the success of the extent to which 成功沒有程度·上的差異
B: reflect both the success of A and the extent to which … 正確OA-B
which前面有介词时要注意把句子恢复成正常语句顺序后再判断是不是正确。有可能出现倒装（谓语单复数判断要小心），主语错误等情况，但也会有像本题这样使用正确的情况！！要小心判断！！
B的现在时 谁能解答一下我
虽然这里的its不在考点范围内，但是是用来指代的company吧，但是company在所有格形式中啊，也可以指代？GMAT真是毫无规则。。。
C核心词不就是extent吗
【C】在逻辑上，“程度”应是降低的程度，而不是汇率本身的程度（汇率没有程度，只有汇率升高或降低的程度）。 因此，本题中extent必须用定语从句来修饰。
