Final answer:
The reaction to increased urbanization, secularization, and new science in the 1920s included the Scopes Monkey Trial, the rise of fundamentalism, and a demand for more science education in public schools.
Step-by-step explanation:
The reaction to the increased urbanization, secularization, and new science of the 1920s was multi-faceted. One significant event was the Scopes Monkey Trial in 1925, where a teacher was tried for violating a law against teaching the theory of evolution. This trial highlighted the conflict between traditionalists in rural areas and urbanites embracing modern science.
Another reaction was the rise of fundamentalism, which emphasized strict adherence to traditional religious beliefs. This led to the teaching of fundamentalism in some schools in the north.
Additionally, the increased urbanization and new science of the twenties resulted in a demand for more science education in public schools, as people recognized the importance of scientific knowledge.
