Answer and Explanation:

When men left their cities to join the armies during the war, a large part of the country's industry and production was paralyzed for lack of workers. However, as war is extremely expensive, it is essential that all productive sectors in a country continue to function and generate money, so that the economy remains active and there is money for the war effort.
