Starting with E, the author never suggests that Morrison is trying to disguise anything about her novel's structural similarity to Duke Ellington's music. Therefore, while nothing in the passage contradicts it, nothing in the passage suggests that the author would agree with it either. However, with D if you look from lines 39-48, the author discusses the way soloists were highlighted but how they were kept within a larger musical framework. The author then suggests that Morrison's narrative style functioned much the same way, which means the analogy between the two artists goes deeper than the simple shift between first-person and third-person narration.
