Which sentence describes why women gained more political power in the 1920s 2?

Women gained more political power in the 1920s primarily due to the passage of the 19th Amendment in 1920, which granted them the right to vote. This newfound political influence allowed women to participate more actively in the democratic process and advocate for social and political reforms. Additionally, the changing social norms and the impact of women's contributions during World War I helped shift perceptions about their roles in society, further empowering them politically.
