Hello GmatNinja,
Can we skip
A,
B and
C Because of wrong usage of
which?
Please clarify on this.
Thanks.
The "which" is definitely a problem, but knowing that "which" modifiers are a bit of a gray area on the GMAT, you probably want to look for other reasons to eliminate A, B, and C.
- (C) is a run-on sentence, so that one's gone right away ("... the water pipes froze, torrents of water were then released...").
- The parallel structure in (B) suggests that the freezing of the pipes is what released torrents of water. That might be true indirectly, but the freezing itself isn't what released the water.
- In (A), we have not one but TWO "which" modifiers, and neither one clearly modifies a specific noun. Instead, both seem to modify the actions of the preceding clauses. Maybe that's not absolutely wrong, but at best it's more confusing than what we have in (E).
- The use of a second "which" in (A) makes it sound as though the "bursting" is what released the water. That's not terrible, but really it's the sprinkler heads themselves that released the water. In other words, the "bursting" may have caused the sprinkler heads to release the water (as suggested by the parallel structure in E), but the "bursting" itself did not release the water.
Are (A), (B), and (C) absolutely WRONG because they violate iron-clad grammar rules? Probably not, but (E) is a much better choice.
In general, if you try to get through SC by memorizing tons of grammar "rules" and blindly applying them, you'll likely hit a plateau. GMAT SC is largely about meaning and logic, so unless the sentence violates a very clear grammar rule (like subject-verb agreement), you want to be conservative and consider other decision points.
I hope that helps!
