What critical issue did First Wave Feminism seek to address regarding women's social position?

First Wave Feminism primarily focused on legal inequalities and the societal status of women, with a strong emphasis on obtaining voting rights. One of its critical issues was the quest for women's suffrage, advocating for the right to vote as a foundational step toward achieving equality. This movement, which emerged in the late 19th and early 20th centuries, sought to dismantle the legal barriers that hindered women's participation in politics and public life.

While access to education for women was certainly an important concern within First Wave Feminism, it did not dominate the agenda to the same extent as voting rights. The suffragists believed that gaining the right to vote would empower women and allow them to advocate more effectively for broader reforms, including improvements in education, workplace equality, and reproductive rights, which became focal points in later waves of feminism.

Thus, the answer focusing on access to voting rights captures the essence of First Wave Feminism's efforts to uplift women’s social position through legal recognition and participation in the democratic process.
