Answer:
The central idea of this passage is:
D. Giving women rights will help both men and women.
Step-by-step explanation:
Mary Wollstonecraft is considered one of the founders of feminism. In this passage of "A Vindication of the Rights of Woman," she defends the idea that women's rights benefit not only women, but men and, consequently, society itself. According to the author, women engage in vanity precisely because they do not have rights. They need to resort to beauty and find devices to "obtain illicit privileges". That would not happen if men and women shared responsibilities and rights. Women would not need to waste their time with vanity. And that valuable time would be better employed, for instance, in obtaining education or helping raise educated children.
