Final answer:
John Dryden employs a Coherence organizational structure in the excerpt provided, focusing on creating a logical and orderly flow based on the progression of the text itself.
Step-by-step explanation:
The organizational structure that John Dryden employs in the excerpt is likely Coherence. This is because the excerpt describes using the poem itself as an organizational guide from beginning to end, suggesting a structure that follows the text's own progression. The mention of organizing a paper thematically or by tackling each idea sequentially, as well as by importance to the argument or poem, indicates that the paper is organized in a manner that creates a logical, consistent, and orderly flow, rather than contrasting or comparing elements, or presenting a problem and its solution.
Dryden's approach seems to be based on a comprehensive understanding of the text, examining elements like word repetition and the importance of certain ideas or images all the way through. These strategies suggest a focus on the coherence of the essay, uniting various parts into a logical whole. This is supported by the recommendation to consider which aspects of the text's form and organization are most significant for the analysis.
