A. Subject to approval by the president
The crops were all destroyed and long gone. The south had battles on many fields that once grew various types of crops. Men went missing who once tended the fields for the crops to go. Many of them ended up injured or even worse, death. Plantations were left abanded and destroyed. Transportation was gone. Railroad lines had been pulled out or torn apart to prevent the south from moving supplies. Even walking to find a way out was very dangerous for anybody.
C. FDR believed that the federal government should take an active role in the economy; Hoover didn't.
President Herbert Hoover is what we call a sitting duck president which means he didn't do anything and believed in a philosophy called "Rugged Individualism". Rugged individualism basically means it's every man for himself and Hoover felt that Americans should figure their issues out by themselves and not rely on the government to help them out.
