Final answer:
President Wilson's program was called the New Freedom, which emphasized a smaller federal government to protect public interest from monopolies and corporate exploitation. This stands in contrast to Roosevelt's New Nationalism that called for a strong federal government to regulate the economy. Truman's Fair Deal, which is not the correct answer, aimed to expand upon the New Deal's social reforms.
Step-by-step explanation:
The idea that President Wilson explained was the basis of a program he called the New Freedom. This program was Wilson's plan and an attack on what he termed the triple wall of privilege: tariffs, trusts, and high finance. Wilson's New Freedom emphasized a smaller federal government aimed at protecting public interest by attacking monopolies and large corporations to ensure they did not dominate the market or exploit consumers.
Wilson's New Freedom contrasted with Theodore Roosevelt's New Nationalism, which sought a more powerful federal government that would regulate corporations and the economy in the public interest. Furthermore, President Truman's program, known as the Fair Deal, sought to build on the successes of Roosevelt's New Deal with additional social legislation. However, the correct answer to the question is c. the New Freedom.
