How did many women assist the u. s. war effort in world war ii?

by fighting alongside men overseas

by producing inspirational radio programs that were broadcast to gis

by working in civilian jobs that had typically been held by men

by running for political offices that men were unavailable to fill

Women were not fighting in the First World War - so the first option is false. They also didn't have voting rights till 1920- so we reject the last answer as well.

The correct answer is that they were  working in civilian jobs that had typically been held by men -this is what contributed to them being able to fight for political rights later.
