Question

Read the opening lines of Sojourner Truth’s speech “Ain’t I a Woman?” Well, children, where there is so much racket there must be something out of kilter. I think that 'twixt the negroes of the South and the women at the North, all talking about rights, the white men will be in a fix pretty soon. But what's all this here talking about? (What tone do these lines convey?) a formal and reserved tone/ a conversational and inquisitive tone /a dissatisfied and pessimistic tone /a hopeful and idealistic tone /

Answer 1

Its a conversational and inquisitive tone* 
because she tells everyone "Ain't i a Woman?" and also when she says "well, children," means that she is talking to someone and proves that this is conversational. 

Answer 2

The correct answer is: a conversational and inquisitive tone.

Indeed, the tone or register is definitely informal. This is not a carefully drafted speech, read with rhetorical method and oratorical inflection. This is actually a very conversational reflection on the issues of gender equality and racial equality.  The speaker is just conversing with the audience in her own plain language in order to convey a more intimate significance to her message on gender equality.

It is also inquisitive because she initially does not use a prescriptive approach for her soliloquy. She actually performs the action of placing the question and then using logic and reasoning to answer it. In this manner she also engages the audience to do the same and arrive at their own conclusions which are of course intended to coincide with hers since her reasoning is already providing the answers.
