Answer:
largely characterized by social activisms and political changes
Step-by-step explanation:
The Progressive Era was a period from the 1890s to the 1920s characterized by widespread social activism and political reform across the United States. It's goal was to address the new problems originated by industrialization, urbanization, immigration, and political corruption. These problems included: violence, racism, poverty, monopoly and corruption by large corporations.
This period also saw the rise in proponents of the Social Darwinists who believed that "only the strong survive". This was vehemently opposed by the progressives who suggested that violence, racism and all social negatives of this time could be eradicated by good education, safer environment, and an honest government.
