Which statement describes a reason for greater support of suffrage and less discrimination against women in the 1920s?

Since we don't have the statements given by the original question, let's talk about the main reasons women's movement got more support in the 1920s.

The women's movement strategy for advancing their ideas was to articulate the struggle for the right to vote to the war mobilization. The U.S. entered the Great War -- that we now call First World War -- in 1917. Also, more women were working outside of the home.

Explanation:

The National American Woman Suffrage Association's (NASWA) strategy during the war was to support it patriotically to show American public women were also part of the war efforts. It worked and in 1919 the 19th Amendment passed.

Another reason for the growth and success of women's movement was the increase of women working outside the home. This greater presence in the public world of work helped to legitimate their demands.
