The correct option is C
The economy, which had experienced an important recovery since the Civil War, was attacked by a double blow by the Great Depression and the Dust Bowl. After the bankruptcy of the stock market in 1929, the economy suffered significant setbacks and thousands of city workers were unemployed, many of whom depended on federal aid programs such as the Federal Emergency Relief Administration (FERA). of Emergency), the WPA (Work Progress Administration, Labor Progress Administration) and the CCC. Farmers and ranchers were especially damaged, as prices of cotton and livestock fell precipitously. Beginning in 1934 and until 1939, an ecological disaster of severe winds and droughts caused an exodus from Texas and Arkansas, the western region of Oklahoma and the surrounding plains, in which more than 500,000 people were homeless, hungry and unemployed. Thousands left these regions forever in order to look for economic opportunities on the West Coast.
