The correct answer is "creation of first suburban housing developments."
The GI Bill helped in giving former veterans educational opportunities and financial assistance. In this case, many veterans used this as a means to receive a low cost mortgage. Since the government was willing to give so many of these low cost mortgages to those who served in World War II, the creation of new houses increased.
One former military man took advantage of this, his name is William Levitt. William created what became known as Levittowns, which were suburban houses built on the concept of conformity. Levitt built successful towns in the northeast part of the US where thousands of former soldiers lived.
The G.I. Bill of Rights or the Servicemen's Readjustment Act of 1944 was signed on June 22, 1944, by President Franklin D. Roosevelt. The bill was created to help veterans from WWII. This bill created hospitals made low-interest mortgages and granted stipends to cover tuition and expenses for veterans attending colleges or trade schools. Based on this we can say that the answer is D, it created the first suburban housing developments.
