The correct answer is B. To help build momentum in her speech
Step-by-step explanation:
In speeches, the momentum refers to the strength or impact the speech has on the audience, which makes the speech memorable. In the case of "Ain't I a Woman" by Sojourner Truth, the main purpose of the speech is to show women are equal in ability, skills, etc. than men, and therefore, they deserve equal rights and treatment. One way the author supports this, is by using the question "Ain't I a Woman?" to demonstrate she does the same things men do, despite men say women need help to do the same things or do not have the abilities. Moreover, the use of this question over and over creates the momentum as this question shows the strength of Truth argument. Thus, option B is correct.
