There was another problem where which was used to refer back to an event or a whole idea.
This is a pdf file on the use of which from a college I never heard of. http://www.jalc.edu/departmentpages/eng ... _which.pdf
As a pronoun to refer back to one single noun or to a whole idea:
a. Referring to one single word:
A week ago I bought a cashmere sweater which cost $150.
(The word which is “re-naming” the sweater.)
b. Referring to a whole idea or phrase:
In 2005, we took a vacation to Walt Disney World, which helped to bond our family members together.
(The word which is referring to the taking of the family vacation.)
To be honest, I'm not too firm on this concept either. MGMAT SC
says that 'which' can modify only nouns and noun phrases, so I am confused.
If anyone can add to this, please do.
Consider KUDOS if my post was helpful.
