Final answer:
Meter affects word choice for a poet but not typically for a prose writer, as poets need to adhere to specific rhythmic patterns that contribute to the musicality and flow of their poetry, which differs from the more flexible structure of prose.
Step-by-step explanation:
A. Meter would affect word choice for a poet but not for a prose writer. While both poets and prose writers must consider readability and clarity in their work, the poet has unique considerations such as meter, which greatly influence their word choice. Meter refers to the rhythmic structure of a poem, and poets often choose words that conform to a specific pattern of stressed and unstressed syllables. This rhythmic framework is much less prevalent in prose writing, where the natural flow of sentences does not usually adhere to such strict rhythmic constraints.
In prose, writers focus more heavily on subject matter, clarity of expression, and comprehensibility. In contrast, poets make decisions about word choice based on how it will affect the poem's meter and the overall musicality of their work. Poets are concerned with the sound and rhythm of language as well as the meaning it conveys, thereby creating a multi-sensory reading experience. Meter thereby becomes a defining characteristic of poetry that sets it apart from prose writing in terms of word selection.
