The correct answer is the need for government assistance.

The Veteran's march on Washington is also known as the "Bonus March." This is when World War I veterans marched on Washington DC to demand their promised bonus from the federal government for their service in World War I. These veterans demanded the bonuses early due to the difficult economic times caused by the Great Depression.

The National Farmer's Holiday took place around the same time as the Bonus Army. This was also during the Great Depression. In this case, the farmers withheld their products from nearby markets as a form of protest for not getting government assistance during these difficult economic times.
