Answer:Using a vast array of media, propagandists instigated hatred for the enemy and support for America's allies, urged greater public effort for war production and victory gardens, persuaded people to save some of their material so that more material could be used for the war effort, and sold war bonds.
Explanation:Through propaganda, Americans promoted production so the American army would be supplied sufficiently and also the American people would have jobs. In the end, The United States and the Allied Powers won the war, so this shows that they were more effective in their attempt.
