你的问题是什么呢？

恳请LZ按发贴规则中写的一题一帖，以便惠及后人，感谢配合。

我也是同样的疑问，C为什么错呢？

顶一下吧。顺便问一句答案是a么，已经快忘了。

现在看c好像有这个问题n+prep+which如果名词和介词中间没有逗号的话，这个介词是什么应该是由前边的名词决定的。请问这样想是对的么

比如说有个题extent of which，因为前边是extent所以后边在用which从句时前边就要加of，而不是因为which从句里的任何 动词决定的。而第一题by好像是由于produce产生的

请指教

感觉c的which代前面的哪个名词就不清楚了,which可以跳跃修饰,到底是代了research还是nature还是processes,没有that来得直接.其他的估计大家看到not...but就觉得优于instead of了,个人认为还是

看哪个错的更严重来判断.

C是不是因为by which造成的，

which指代proecss, the launguage is produced by process还勉强说的通．但与之并列的，the launguage is understood by process 似乎说不通吧．

那能讲讲which前的介词到底是由谁来决定的么，in general

什么时候要看which后边的动词，什么时候要看前边的名词呢，和有没有逗号有关系么？谢谢
