Answer:
A. Social attitudes about women made change difficult.
Step-by-step explanation:
Before the 1920s, Americans had a very traditional and simplistic view of women. Women were usually considered to be responsible for the "domestic" aspects of life, such as taking care of children, cooking, cleaning, etc. Women's impact in the social and public sphere was very reduced, usually linked to the church or to charitable roles. These social attitudes about women made change very difficult.
