Answer:
A-He uses dialect to better connect the message to the intended audience.
Explanation:
In this poem, we see that the dialect is one of rare poetries. We are able to understand that the "caged bird" can resemble different things. An animal trapped, or a human stuck in its own mind.
A caged bird beats its wing, or it sings. It's praying to the Heavens above, wishing for something else, for a miracle to come through to him/her.
I think that this is a way for the poet to connect to its intended audience, of which are the people that feel trapped and alone. Why they do the things they do. They don't intend to fully harm themselves or sob, but they wish to have a different fate, and they pray that one day, if they continue to do it, a miracle will come their way.
At least that is my interpretation of the poem. The caged bird is to resemble a person who is stuck in their thoughts, lost in their mind, not knowing what to do next. I feel the intended audience is those people, and the people who feel that way but don't know it yet.
I hope this helps!
