Answer:
One effect of the expansion of the federal government during World War I is that the federal budget went from less than $800 million in 1916 to $18 billion by 1919.
Step-by-step explanation:
Although it was easier for the federal government to draft men for World War I, it couldn’t easily get most of the resources needed for war like food, arms, ammunition, goods and services, and equipment. Therefore, it had to devise a means to acquire sufficient revenue: it increased federal outlays from $800 million in 1916, to $12.7 billion in 1918, and later to $18.5 billion in 1919.
