What is rhetoric and why does rhetorical make the writing or speech more effective ain’t i a woman

I haven't read the writing or speech, "ain't I a woman" but from background knowledge, I know that rhetoric and rhetorical devices are used to persuade the audience of something.

As I don't know what the speech is about, I couldn't tell you what makes it effective but your answer is going to most likely be a type of rhetorical device.

Ask yourself...

What does the speech use more of?

Those are some examples of rhetorical devices. I know I haven't read the speech but I hope I was at least some help :) Let me know if you have anymore questions.

a.) literature that explores grotesque characters and eerie, violent occurrences in a dreary setting.

voracity is the noun corresponding to the adjective voracious, which means (1) eager to consume a great amount of food, or (2) marked by an insatiable appetite. veracity is far more common than the rare voracity, so the latter is sometimes used in place of the former.
