Choice B is the best answer. In lines 16-31("it...they"), Stanton argues that men make all the decisions in "the church, the state, and the home." This absolute power has led to a disorganized society, a "fragmentary condition of everything." Stanton confirms this claim when she states that society needs women to "lift man up into the higher realms of thought and action" (lines 60-61,"thought...step").
Choices A and D are incorrect because Stanton does not focus on women's lack of equal educational opportunities or inability to hold political positions. Choice C is incorrect because although Stanton implies women are not allowed to vote, she never mentions that "poor candidates" are winning elections.
