Question

to prepare the country for World War 1, what became an early focus of American industrial mass production? ships, airplanes, automobiles, or ammunition

Answer 1

boats, equipment and supplies.

Step-by-step explanation:

to be honest, America actually didn't count on being in the great war. (thanks to Woodrow Wilson) but in the final year of the war, America entered the war which caused a increase in demand for boats (to transoort troops) equipment (to arm the troops) and supplies (to rearm and feed the troops).
