Which of the following interpretations of progressivism would most likely support the view that progressives were a diverse group?

The interpretation that supports the view that progressives were a diverse group is grounded in their engagement with a broad spectrum of social and political reforms. Progressivism emerged in the late 19th and early 20th centuries as a reaction to the rapid industrialization and urbanization occurring in the United States. This movement attracted individuals from various backgrounds, including labor activists, middle-class reformers, suffragists, and various interest groups, all advocating for changes in different aspects of American society.

Supporters of various social reforms aimed to address issues like child labor, women's suffrage, and racial equality, while political reforms included advocating for direct democracy measures such as referendums and initiatives, as well as tackling corruption in government through campaign finance reforms and the establishment of regulatory agencies. This diversity in goals and the wide range of issues that progressives sought to reform highlight their varied backgrounds and priorities, illustrating that progressivism was not a monolithic movement but rather a coalition of groups united by a desire for change.
