Final answer:
The quotation from "Ain't I a Woman?" serves as an example of ethos, as it showcases Sojourner Truth's personal experiences that lend credibility to her arguments for women's equality.
Step-by-step explanation:
The quotation from Sojourner Truth's "Ain't I a Woman?" speech is an example of ethos because it demonstrates that Truth has the relevant personal experience and credibility to support her claims for women's rights. Ethos is a rhetorical device that establishes the speaker's credibility and appeals to the audience's sense of trust.
In this context, by recounting her own hard work, traditionally considered a man's work, Truth effectively challenges societal norms and positions herself as a living contradiction to societal assumptions about women and their capabilities.
