Final answer:
The United States played a significant role in World War I socially, economically, and politically.
Step-by-step explanation:
The United States played a significant role in World War I socially, economically, and politically. Socially, the war led to major changes in American society, including the Great Migration of African Americans from the South to Northern cities and a shift in women's roles as they entered the workforce to take on jobs traditionally held by men. Economically, the war boosted the American economy, as the United States became a major supplier of goods to the Allied powers. Politically, President Woodrow Wilson's vision for a postwar world of peace and collective security, as articulated in his Fourteen Points, was a driving force behind U.S. involvement in the war and the subsequent negotiations for the Treaty of Versailles.
