Final answer:
The poem's theme is most effectively developed through symbolism interpretation, which involves analyzing recurring motifs and symbols to understand deeper thematic messages.
Step-by-step explanation:
The details in the poem that most clearly develop the theme identified in part A are best summarized as symbolism interpretation. Symbolism allows the reader to understand deeper meanings and themes that are often not directly stated but implied through objects, characters, motifs, or events. By examining objects or elements that recur and signify particular concepts or themes, one can extrapolate a story's possible themes. For instance, a motif of a park in a story might symbolize innocence and childhood, and changes to this setting could depict the theme of growing up and loss of innocence. Additionally, understanding how the plot, setting, and characters work together can underscore the thematic message that the author wishes to convey.
