I'M REALLY STUCK ON THIS How did U. S. participation in ​World War I​ affect the American civilian population?

a.)Fewer farmers were able to produce crops, so there were food shortages across the country.
b.)With men drafted to serve in the military, jobs became available for women and minorities.
c.)Civilians could not keep up with the supply demands of the military.
d.)Children over age 14 had to take jobs because there was a labor shortage.
