'Which' can also modify the noun phrase 'Independence-war of America' and the sentence is correct as is it is....correct me if I'm wrong...??
Very
unlikely that
which will modify the entire noun-phrase
Independence-war of America, since (as mentioned in my post above)
which has a tendency to modify the
nearest grammatically eligible word (in this case,
America).
This is similar to the
official example I cited in my post above, where
which is
not modifying the noun phrase
lake on Earth, but only the word
Earth (again
because Earth is the
nearest grammatically eligible word).
Even if you do
not straight away
reject these kind of answer choices, keep such options on the
back-burner and revisit them
only when there is something
significantly wrong with all other answer choices.
