Answer:
1929
Step-by-step explanation:
The "Roaring Twenties", the decade following World War I that led to the crash was a time of wealth and excess. Building on post-war optimism, rural Americans migrated to the cities in vast numbers throughout the decade with hopes of finding a more prosperous life in the ever-growing expansion of America's industrial sector.
On October 29, 1929, "Black Tuesday" hit Wall Street as investors traded some 16 million shares on the New York Stock Exchange in a single day. Billions of dollars were lost, wiping out thousands of investors. The panic selling reached its peak with some stocks having no buyers at any price. The Dow lost an additional 30.57 points, or 11.73%, for a total drop of 68.90 points, or 23.05% in two days.
