The correct answer to this open question is the following.
The change in the domestic United States during the Second World War from 1939 to 1945 was primarily in the role women played in the workforce. As most men had to enroll in the military to participate in World War II, the factories of America needed hands to produce the weaponry and supplies that needed to be sent to the European war front. That is when women had to leave their homes to start working in the fabrics and manufacturing plants of the United States. This factor was key to keep on producing the much-needed supplies for the war.
Another important aspect was the Victory Gardens that the federal government asked citizens to have in their backyards. The government asked Americans to grow their own crops in their backyards to help the war effort.
A rule made by the government is a law.
