Final answer:
The most immediate problem for the federal government during the Great Depression was high unemployment, with a peak unemployment rate of 25% and significant economic downturns.
Step-by-step explanation:
The most immediate problem to the federal government during the Great Depression was high unemployment. At its peak between 1929 and 1933, the national unemployment rate reached 25%, with a considerable decline in industrial output and a substantial number of banks going out of business. The situation was so severe that the government stepped in with New Deal programs to provide relief and create employment opportunities.
In contrast to the Great Depression, the early 1920s in Germany witnessed a different economic issue: hyperinflation, which drastically escalated prices and devalued the currency.
