Brief Explanations:

After World - War I, the US experienced a building boom. Construction activities in housing, commercial buildings, and infrastructure contributed significantly to economic growth. Loans from abroad were not the main driver. Inflation was a problem rather than a source of economic reliance. While farming was important, construction had a more prominent role in the post - WWI economic landscape.
