Final answer:
The structures of poems by Emerson and Whitman differ, with Emerson tending toward more formal rhyme schemes and Whitman favoring free verse and repetition.
Step-by-step explanation:
The structure of Emily Dickinson's and Walt Whitman's poems differ notably. Dickinson's poems typically follow traditional rhyme schemes and are often short in length, using dashes to create abrupt breaks. In contrast, Whitman's poetry is known for its use of free verse, which doesn't adhere to a consistent rhyme or meter, and can vary greatly in line length. When comparing an Emerson poem to that of Whitman's, option (A) suggests Emerson uses an ABAB rhyme scheme, indicating a structured approach, while Whitman's has no regular rhyme scheme, which points to a more freeform style. Option (C) brings out that Emerson's poem does not follow a set rhyme scheme, contrasting with Whitman's use of repetition as a poetic device. Whitman's poetry is often characterized by its lack of conventional structure, focusing instead on natural cadence and rhythm, which can be seen in his frequently enjambed lines and use of caesura to emphasize meanings within his poetry.
