Final answer:
The U.S. Government's policy to regulate crop prices during the Great Depression was the Agricultural Adjustment Act (AAA), which involved paying farmers not to plant and to reduce livestock.
Step-by-step explanation:
As a response to the hardships of the Great Depression, particularly in the agricultural sector, the U.S. Government instituted policies to regulate crop prices and stabilize the economy. One significant policy was the Agricultural Adjustment Act (AAA), which was part of President Franklin D. Roosevelt's New Deal. Under the AAA, the government began paying farmers not to plant part of their land and to reduce livestock numbers, thereby reducing the surplus in order to raise commodity prices. This approach was unprecedented at the time and marked a new level of federal intervention in the economy. Additionally, the government also implemented agricultural extension programs to educate farmers on better farming practices to avoid future environmental disasters, such as the Dust Bowl.
