Final answer:
False. The key driver of the 1920s economic prosperity in the United States was not the agricultural sector, but rather industries such as mass production and automobile manufacturing.
Step-by-step explanation:
False.
While the 1920s were indeed a decade of prosperity and explosive economic growth for the United States, the key driver of this economic prosperity was not the agricultural sector. Instead, industries such as mass production, especially of the automobile, played a significant role in driving the economic growth. The agricultural sector, on the other hand, faced overproduction issues and struggled to make a profit. As the decade came to a close, the slipping economy would soon crash, leading to the Great Depression. So, while the 1920s were a period of relative economic success, it was not driven primarily by agriculture.
