Final answer:
The creation of Superman and comics did not significantly affect production and culture post WWII; instead, the other factors like the Cold War, the Marshall Plan, and the rise of pop and mass culture had more direct impacts on society and the economy.
Step-by-step explanation:
The question asks which factors affected production and culture in the post WWII period (1945-1960), except one particular factor. The Cold War and ideological battles such as socialism and communism, the Marshall Plan and Europe's cultural recovery, and the rise of pop and mass culture all profoundly impacted the period. However, the creation of Superman and comics, while culturally significant, was not a direct factor that affected production and culture on the same large scale as the other options. The superhero genre may have reflected and influenced cultural sentiments, but was more a result of the evolving pop culture landscape, rather than a driving force behind the broad economic and societal changes of the time.
Postwar consumer culture, economic prosperity, and social changes were marked by increased mass production and a shift to a consumer-driven economy. The Economic aid provided by the Marshall Plan helped rebuild European economies, which in turn affected global markets and politics. The Cold War significantly influenced not just geopolitics but also domestic policies and cultural attitudes toward capitalism and communism in the United States.
