Hi...it would be a great learning experience if can you share those sentences... may be we can ask Bkimball to evauluate same.
I also forgot to mention in my post that there is an exception where which might not refer back to immediatly preceding word. when preposition is used as a part of group of words preceding which , pls see the below mentioned example
If antecedent is a part of the prepositional phrase before "which" , "which" may not directly refer back to words it is attatched with.
The picture above fireplace, which was taken last year in mexico, is one of my favourites
here , which refers to the picture taken, in such situations :
1) we must try to rephrase the sentence, if possible to ensure that "which" touches the preceding word.
2)if that is not possible to rephrase sentence then there is no harm in usage of which as mentioned above
the ideal construction with which / that is what has been described in above posts, and almost every time i hve seen the usage of "that and which "as per the rules authenticated by Bkimball.
usage of "which and that" is the one of the most important points in GMAT, and i hve explained something on the fundamentals of this rule, so i would request you to correct me if i am wrong anywhere in my explanation, so there is no misunderstanding on this rule and my post doesnt misguide anyone
because i am not master of verbal , just learning
Can you also address two questions along with this
1) how frequently do we see usage of which , where "where" might not refer back to immediate preceding word ? ( in context of GMAT )
2) If you could address any situation where "which" might refer back to entire clause preceding "which"(as mentioned by ( metallicafan in one of the previous posts ) because i am yet to learn this aspect if there are any exceptions
