Final answer:
World War I is NOT considered a direct 'Root Cause' of the Great Depression; rather, it had broader global economic implications. The Great Depression was more directly caused by domestic financial policies and socio-economic conditions within the United States.
Step-by-step explanation:
Root Causes of the Great Depression
The question asks which factor is NOT one of the 'Root Causes' of the Great Depression. When examining the origins of the Great Depression, several key economic factors come to mind. These include mistakes by the Federal Reserve (such as poor monetary policies), the uneven distribution of income across the population, credit availability and the resulting excessive debt that many consumers and businesses took on. However, World War I (WWI) is not considered a direct 'Root Cause' of the Great Depression. While WWI had massive global economic implications, the specific economic conditions leading directly to the Great Depression, particularly in the United States, were more closely tied to domestic financial policies and socio-economic conditions of the 1920s.
