The repetition of the word singing influences the overall meaning of the poem "I Hear America Singing" by Walt Whitman as the repetition emphasizes hope and a unified vision for America. Here, the right answer is option D.
Step-by-step explanation:
In this poem, the alternative way to read the effect of the repetition of the word "singing" is said to be a "democratizing effect."
