Question

How did TWO of the following help shape American national culture in the 1920s? Advertising, entertainment, mass production.

Answer 1

The 1920s in the United States, in the years leading up to the great crash of 1929, were a period of rapid economic development, brought about in many ways by mass production during and after World War I. A rebirth of advertising allowed more of these goods to be purchased, which greatly increased US GDP.
