Question

how did womens roles in the workforce change during world war i?
○ women entered the industrial workforce for the first time.
○ women replaced men as workers in factories.
○ women fought in the war alongside men.
○ women became the primary earners at home.

Explanation:

During WWI, men left factory jobs to fight, so women filled these roles. "First time" is incorrect (women had industrial work before), women rarely fought in combat, and "primary earners" wasn’t universal. The key change was replacing men in factories.

Answer:

Women replaced men as workers in factories.
