In the 1920s, the continued rise in the stock market and economic growth depended most on
a) bankers buying stocks with cash.
b) investors buying stocks with cash.
c) consumers buying goods on credit.
d) consumers growing their own food.

The third alternative is correct (C).

The 1920s were a great moment in the American economy. The US had become the largest economic power in the world and set up a large manufacturing industry. All production was sustained by high demand, it was a time when consumerism exploded in the United States.

Thus consumers demanded credit and bought the goods and services that were produced by the companies. The problem is that this model of support for consumption has run out. Driven by consumption, production increased so much that it went so far that there was no further demand to dispose of all production. So the credit market collapsed, the Crash of the New York Stock Exchange happened and the country entered the Great Depression.
