Final answer:
A verse novel differs from a long poem by incorporating language and style elements from novels, such as in-depth character development and a broad setting or time span.
Step-by-step explanation:
According to Hirsch's definition, a verse novel is distinct from the long poem due to its incorporation of certain patterns of language and stylistic elements found predominantly in novels (c). Unlike short stories or plays, which have more condensed narratives or are constrained by the setting of a stage, novels often span long periods of time, feature a broad range of characters, and unfold in diverse locations. The verse novel will emulate these aspects through a narrative structure delivered in poetic form, combining the essence of poetry with the depth and development typically associated with a novel.
