Hi
egmat,
GMATNinja, Why is learned to distrust and neutralize not correct distrust and neutralize are verbs and cant they be nested under the preposition to?
You could argue that the repeated "to" makes the parallelism a bit clearer in (D). But there's nothing inherently wrong with "learned to distrust and neutralize," so that's probably not a strong enough reason to eliminate (A) or (E).
But there are other reasons why (D) is better than (A) and (E).
In (A), "because that" is redundant. Also, "because" isn't appropriate since the sentence starts with, "The reason is ____." So we need to fill in the blank with the reason itself ("that the inhabitants learned..."), not "because + [the reason]." You'd have to eliminate "the reason" from the beginning in order to use "because" (i.e. "Many people consider the island to be ungovernable BECAUSE the inhabitants learned...").
In (E), "was" doesn't work, as explained in
this post.
I hope that helps!
