I am getting confused with the usage of "which".
It appears to be quite a popular mistake in GMAT SC questions.
Maybe we can start a thread on this subject.
We could add questions where "Which" is used correctly and incorrectly
- who: for people
- which: for animals and inanimated things
a relative pronoun and must refer to its closest antecedent.
Which is different from who or what because it asks for a choice from a definite, limited set of possibilities.
It can also be used to start a non-defining clause
Question concerning the usage of Whichhttp://www.gmatclub.com/forum/p365826#365826
A few things about 'which':
1) in GMAT, 'which' usually follows a comma
2) 'which' should not replace a person (use who or whom for that)
3) 'which' is used for the part of the sentence that is not essential for the meaning of the sentence to hold. Vs. 'that' is used for the part of the sentence that is essential for the meaning of the sentence to hold.
Makes any sense?
