Step-by-step explanation:
In Sojourner Truth's speech 'Ain't I a Woman?', the repetition of the phrase 'Ain't I a woman?' throughout the second paragraph serves to challenge the prevailing notions of both gender and racial inequality.
By recounting her physical and emotional strength in experiences typically associated with men, such as working tirelessly and enduring the pain of having her children sold into slavery, Truth underscores her resilience and determination which match or exceed those of men.
The repetitive questioning emphasizes her femininity in conjunction with her strength, thus reinforcing the message that she deserves the same rights and recognitions afforded to women and men alike.
