Final answer:
During the Great Depression, the most common source of income as jobs became scarce was C) Selling homemade crafts and goods, because the stock market had crashed, and significant government welfare programs were not yet widespread.
Step-by-step explanation:
During the Great Depression, jobs were indeed scarce, and people had to find alternative sources of income to survive. The correct answer to the question is C) Selling homemade crafts and goods. While some may think that government welfare programs or the military could have been sources of income, during the early years of the Depression, the federal government did not provide welfare programs at the level seen in later years or during wartime. There were no large-scale government employment programs until Franklin D. Roosevelt began the New Deal. Moreover, investment in the stock market was not a common source of income since the stock market crash in 1929 was a major cause of the Depression. Selling homemade crafts and goods became a way for people to try to make ends meet during these challenging times. Many people used their skills to create products they could sell, which was one of the few ways to earn money when formal employment opportunities were limited.
