Answer:
The correct answer is: Women were not allowed to enter the military, so they worked in factories and increased war production.
Step-by-step explanation:
World War II gave an opportunity for American women to start working mainly in the defense industry. Although there were a lot of stereotypes against working women, they worked in factories, as an important working force around the world. Some of them also worked as nurses, truck drivers, clerks or repaired planes.
After the war, many women got fired from factories.
