I'm happy to help with this.
First of all, you may find this blog helpful:http://magoosh.com/gmat/2013/modifiers- ... orrection/
Here, the first part of the sentence states a fact, and that fact overall, that entire situation, causes folks to ask questions. We need to modify a clause. (A)
use the pronoun "it
", which presumably has the antecedent "tiger
", but the tiger itself didn't cause some to ask questions. That's nonsense. (C)
uses verb parallelism again to make the tiger the cause ---- "A tiger escaped ... and caused
..." --- again, poppycock. (D)
puts a verb in parallel with a participle, a total trainwreck. (E)
is correct. A participial phrase, such as "causing some to question
...", can modify not just a single noun but a verb or even an entire phrase. That's exactly what is happening here.
Does this make sense?
