Final answer:
The correct answer is option 1. The march of the "Bonus Army" and referring to shantytowns as "Hoovervilles" in the early 1930s illustrate growing discontent with Republican efforts to deal with the Great Depression.
Step-by-step explanation:
The march of the "Bonus Army" and referring to shantytowns as "Hoovervilles" in the early 1930s illustrate growing discontent with Republican efforts to deal with the Great Depression. This was a period of widespread economic hardship in the United States, with high unemployment rates and poverty.
The Bonus Army, consisting of World War I veterans, demanded early payment of their bonuses and set up shantytowns in Washington, D.C., to protest. President Hoover ordered the military to forcefully disperse the protestors, which further fueled public anger and discontent with the Republican administration's handling of the crisis.
