Answer:
The correct answer is "Personification."
Step-by-step explanation:
Personification is a figure of speech or literary device that gives an object or nonhuman character a quality often related to humans.
In this case, the author, Walt Whitman, is giving the ability to sing to the concept of America, a nation, refering to the idea of the entire country interconnecting and sharing a single identity.
Other examples of personification could be:
- The wind whispered in my ear.
- The flame danced on top of the candle.
- Time doesn't wait for anyone.
