MAGOOSH EXPLANATIONThe most common idioms of consequence are
→
so [adjective] that→
such [noun] thatChoice (A) uses the first idiom. It is sleek and elegant: no problems.
Choice (B) opts for the second idiom, turning the adjectives into nouns, and it omits the
that—this omission makes this answer too casual for the GMAT, whereas turning the adjectives into nouns makes it too stilted.
This answer choice fails in both directions! Choice (B) is incorrect.
Choice (C) is hyper-dramatic, far more dramatic and emphatic than the context demands.
Furthermore, the dramatic rearrangement introduces a second
that, which is confusing.
The words
that and
it each appear twice, each doing different things—very confusing!
Choice (C) is incorrect.
Like choice (B),
choice (D) turns the adjectives into nouns and omits the
that. This rendition is even more hyper-dramatic than (B), but it has the same casual omission of “that.”
Option D seems to suggest, illogically, that the
improvement and not the
engine became widely available.
It’s also strangely passive and indirect.
Choice (D) is wrong for a number of reasons.
Choice (E) is extremely indirect, passive, and livy-livered.
Like (D), this option illogically suggests that the
improvement and not the
engine became widely available.
Choice (E) is grammatically correct but it has rhetorical and logical problems. Choice (E) is incorrect.
Choice (A) is the best answer.
