Final answer:
Sojourner Truth's speech was centered on demonstrating her strength as a woman and advocating for the inclusion of African American women in the women's rights movement.
Step-by-step explanation:
Sojourner Truth's speech calling for equality was centered on her demonstrations that she was as strong and resilient as any man.
In her speech, she addressed the intersection of the women's rights movement and the abolition movement, advocating for the unique acknowledgement and inclusion of African American women's experiences in the fight for women's rights.
