Final answer:
Demobilization following World War I is NOT an example of controversy about cultural changes or the conflict between traditional and modern values during the 1920s.
Step-by-step explanation:
During the 1920s, there was indeed a significant conflict between traditional beliefs and modern thought. Option (b) Demobilization following World War I is NOT an example of controversy during the 1920s related to cultural changes or the conflict between traditional and modern values. The Volstead Act (a) represents the prohibition movement, the Scopes Trial (c) stands for the clash between science and religion, and the choices made by flappers (d) symbolize the new freedoms and behaviors of young women challenging traditional norms. Demobilization post-World War I was chiefly an administrative and logistic process, not a cultural controversy.
