Final answer:
The appearance of Quonset Huts in the 1940s on the IU campus was attributed to the post-WWII housing shortage, the demand for real estate, and the influence of streamlined construction innovations.
Step-by-step explanation:
All of the following were factors causing Quonset Huts to appear on the IU campus in the 1940s: post-World War II housing shortages, a surge in demand for real estate, and the need for quick and affordable housing solutions for veterans returning from the war and the growing population. Quonset Huts were prefabricated, semicircular structures that were easy to assemble and provided a rapid response to the urgent need for housing. This situation was a direct consequence of several factors, such as the interruption in home construction during World War II as national efforts focused on war production, and the postwar boom that created a significant demand for new housing. Additionally, Frank Lloyd Wright's innovation in prefabricated concrete block systems and the Usonian-style homes influenced the streamlined construction methods used in the postwar era. The concept of mass-produced homes, such as those developed by William Levitt in Levittown, also reflected the societal shift towards suburbanization and mechanized construction techniques.
