Final answer:
The First Wave benefited from the skills and experiences of the Second Wave, which focused on the elimination of social and economic discrimination on top of the legal discrimination addressed by the First Wave.
Step-by-step explanation:
The question seems to be related to the impact of the Second Wave Feminism on groups who were part of the First Wave. Option C) suggests that they benefited from the skills and experiences of the Second Wave. When discussing social movements, especially those surrounding the women's rights movement, such as Second Wave Feminism, it's important to recognize that they didn't occur in isolation. Second Wave Feminism was a movement that not only aimed to eliminate legal discrimination but also the social and economic discrimination against women, which persisted despite the gains from the First Wave.
During the First World War, women and black people had opportunities for advancement by assuming roles traditionally held by white men. Following the war and during the Second Wave, the First Wave groups' position in the social hierarchy was influenced largely by societal shifts toward greater equality in the workplace and the push for anti-discrimination legislation. For instance, the Equal Rights Act and the Civil Rights Act of 1964 worked to ban wage discrimination and discrimination based on sex, contributing to an ongoing transformation of the workplace and society that the First Wave had initiated. Thus, while the Second Wave did not explicitly move First Wave groups up the social hierarchy, their actions regarding social and economic rights directly and positively impacted those initial gains.
