“You see, once, I came across a picture of a strange looking violin. The caption said that it was made out of a rifle.

I thought to myself, ‘Someday that could be me’.”

What is the central idea of this poem?

The central idea means that person could be made out of something.

are their choices tho?

both the address and the poster use diction to convey their message. diction is defined as a style of writing or speaking based on the types of words chosen in order to send a message. parallelism is when a similar sentence structure is used for several sentences on a text; roosevelt's address doesn't follow that. repetition has to do with repeating a word or sentence in order to emphasize and idea, however neither the poster nor the address use repetion. finally, the address doesn't use images to convey a message.
