Question

what was one effect of the expansion of the federal government during world war i?
many social service agencies came to the aid of the poor and elderly.
the efficiency of the federal government increased significantly as more agencies were established.
the military gained both domestic and international power.
the federal budget went from less than $800 million in 1916 to $18 billion by 1919.

Explanation:

During World War I, the U.S. federal government expanded drastically to manage the war effort. This included a massive increase in spending to fund military operations, supplies, and related initiatives, leading to a huge jump in the federal budget. The other options are incorrect: social service aid for the poor/elderly came later with the New Deal, the expansion actually created bureaucratic inefficiencies, and while the military gained international power, the budget shift is a direct effect of federal expansion.

Answer:

The federal budget went from less than $800 million in 1916 to $18 billion by 1919.
