Which of the following was NOT a cause of the Great Depression?

A. Abuse of credit
B. U.S. dominates trade and production
C. FDR's New Deal program
D. Stock Market crash

To determine which of the options was NOT a cause of the Great Depression, we need to analyze each option and understand its relevance to the economic downturn.

A. Abuse of credit: During the 1920s, there was a significant increase in consumer spending fueled by a reliance on credit. This led to overextension and an inability to repay debts, contributing to the economic collapse.

B. U.S. dominates trade and production: The United States indeed became the dominant economic power during the 1920s; however, this factor alone does not exclude it as a cause of the Great Depression.

C. FDR's New Deal program: The New Deal was a series of economic programs implemented by President Franklin D. Roosevelt to combat the effects of the Great Depression. Therefore, it cannot be considered a cause of the depression itself.

D. Stock Market crash: The stock market crash of 1929 is widely recognized as the initial trigger and a crucial component of the Great Depression.

Based on the above analysis, the option that was NOT a cause of the Great Depression is C. FDR's New Deal program.
