Just a technical point. As much as possible, type stuff out instead of using jpgs or other image files. When we hit reply, image files don't show up in the list of previous posts at the bottom of the reply page, so we can't easily refer back to the problem. I have to keep going back and forth in my browser window, which takes more time - and the more time we take to answer one question, the less time we have to answer other questions. Thanks!
There are some circumstances in which the word "which" does not refer to the immediately preceding noun, but it still refers to the immediately preceding MAIN noun.
He admired her aura of invincibility, which made her seem like Superwoman.
Here, the "which" clause is referring to aura, the main preceding noun. "of invincibility" is just a small descriptive phrase attached to aura.
When this does happen on the GMAT, the intervening prepositional phrase tends to be pretty short - maybe 5-6 words max. I don't recall seeing one like the canoe example, in which there are actually two descriptive phrases, not just one, and there are a lot of words between the main noun and the "which."
Do you know the source for that question? I really don't recommend using materials from sources other than OG and any companies large enough to spend a lot of money on R&D for sentence correction. For everything, really, but for verbal in particular - it's REALLY hard to mimic verbal stuff and the GMAT doesn't test every possible permutation of the grammar rules, so you don't want to waste time learning what the GMAT doesn't test, or learning things that will cause you trouble with the way that GMAT does test things.
The "exam" example given is not correct usage of "which." That may sound okay to a lot of people, because we speak that way every day. It's just not actually proper grammar.
