Why would an author use hyperbole?

A

Explanation:

Authors use hyperbole to evoke strong feelings or emphasize a point. Hyperbole can be used to overstate any type of situation or emotion, and can be used humorously or seriously. Hyperbole is most often found in poetry, as poets use it to make comparisons and describe things in more embellished terms.

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.
