The correct answer is "a lack of credit."
President Hoover urged Congress to establish the Reconstruction Finance Corporation (RFC) because he believed that the economy suffered from a lack of credit.
On January 22, 1932, the United States Congress established a government agency called Reconstruction Finance Corporation that was created by President Hoover to support railroad construction and different business in America. The plan, as well as the Emergency Relief Act of July of the same year, were set to help the American citizens and the economy. So it is true that President Hoover urged Congress to establish the Reconstruction Finance Corporation (RFC) because he believed that the economy suffered from a lack of credit.
