Here's the
official explanation provided by the GMAC for this question:
The sentence tells us that prior to the seventeenth century melancholy was regarded as a disease. There were two associated beliefs concerning melancholy: (1) it was caused by an excess of black bile; (2) it had as its symptoms delusions, hysteria, distemper, and paralysis. These beliefs can be correctly expressed by parallel modifying phrases conjoined by
and.Option A: Two flaws disqualify this answer choice: the unidiomatic pairing of
to be with
regarded and the disruptive and unnecessary insertion of
one.
Option B: This answer choice is disqualified by the use of
to be rather than
as following
regarded and the unnecessary insertion of
one.
Option C: This answer choice incorrectly represents the claims about bile and the supposed characteristics of melancholy as if they are currently accepted facts rather than centuries-old beliefs no longer regarded as true. This version fails to clearly represent these claims as part of the pre-seventeenth-century view of melancholy. Furthermore, the wording
was regarded a disease is unidiomatic;
was regarded as a disease is the correct expression.
Option D: As with answer choice C, this version can be read as endorsing the pre-seventeenth century views about the causation and symptoms of melancholy. This reading would result from taking the phrase
being caused … body … and paralysis as modifying the subject of the sentence,
melancholy.Option E: Correct. The parallel phrases
caused … body and
characterized … paralysis modify
disease and are correctly conjoined by
and. The preposition
as is the correct usage with
regarded.The correct answer is E.
