Which rhetorical technique does the speaker use

Ethos, pathos, parallelism

Explanation:

The author of this excerpt uses ethos when she lists all the things that she is able to do. She tells us that she is able to work as hard as a man, eat as much as a man and tolerate lashes as well as a man. By outlining her experiences, she makes a claim to her credibility that proves very persuasive.

The author also uses pathos by presenting many scenes that are emotionally charged. The author tells us that she received lashes, that she often could not find enough food to eat and that she has lost all of her children.

Finally, the author uses parallelism because the structure of all the sentences is similar, and she repeats the phrase "Ain't I a Woman?" constantly.
