OG的解释是有3个原因:1。后面的主语是firms,所以之前要reference. 但比如说,Finished homework, I went home. 为什么一定要reference呢?
2。survive的subject要说明 3。require 的宾语要说明。姑且就按照OG这么记吧……
关于这道题我还有一个疑问,就是because of ,印象中选项中出现它就是一定错的,因为它只能接名词。那么这里面它管到哪呢?也就是说and连接的是哪两个并列成份呢?
谢谢了!!

the enormous [research and development] expenditures是一個名詞.

Finished homework, I went home. 中的finished是要改成"finishing" or "after finishing"才可能grammatically correct...因為finish是由主句的主語actively做的, 而不是passively...

要有reference因為之後的主句refer back to the firms...such firms
