because in question 48 og 13, "earth" is eligible to be modified by "which" A and B are wrong.
can I summarize as following
if we have
X of Y, which
if Y is eligible to be modified by "which", "which" modifies Y
if Y is not eligible and if Y modies X and can not be placed elsewhere, "which" modifies X
if Y is not eligible and dose not modifies X, we have pattern wrong on gmat. for example:
I learn English in a good method, which is a beautiful language.
is not acceptable on gmat.
pls, confirm
The problem in 48 is not that "which covers more..." is modifying Earth. It could be modifying the largest lake on Earth. Both are incorrect. That phrase should be modifying Caspian. Notice the difference:
The Caspian, which is blue, is the largest lake on Earth. (the Caspian is the largest lake on Earth)
The Caspian is the largest lake on Earth, which is blue. (the Caspian is the largest blue lake on Earth)
