OE
This question is an excellent lesson in the principle: don’t add anything to your reading of the sentence that wasn’t there already. The sentence indicates that the first short story collection had many diverse voices and the second collection has “a ________ narrator”—in other words, just one speaker. The word “sole” fits the third blank; neither “lonely” nor “disingenuous” convey the idea of a single narrator. The first story collection was a “hodgepodge” (jumble), but the second was not a jumble; it was an “even” set of stories. “Insightful” and “facetious” (not serious) are not antonyms for a jumble. For the first blank, “motley” works because it means composed of diverse and often incongruous elements. “Variable” is a trap: a variable hodgepodge of voices would imply that the voices in the first collection can change over time, not that the voices were varied or diverse. And “homogenous” would indicate that the voices were all similar; this describes the second collection, not the first.
