Final answer:
During the Progressive Era, key reforms focused on social, economic, and political issues, but 'Environmental Reform' was not explicitly termed as such, although some efforts did lay groundwork for later environmental movements. 'Environmental Reform' is the option that is NOT a type of reform identified during the Progressive Era.
Step-by-step explanation:
The Progressive Era was marked by various types of reform efforts aimed at addressing the vast social inequities and problems brought about by rapid industrialization and urbanization in the United States at the turn of the 20th century. The movements within the era focused on different areas of reform, which did include social reform, economic reform, and political reform. However, 'Environmental Reform' as named in the presented options was not explicitly called out during the Progressive Era in those terms, although there were some efforts that would influence later environmental movements. Instead, the reform movements during this period were much more focused on immediate human-related issues such as improving living conditions, regulating business practices, expanding democracy, and advocating for social justice. In related reform discussions, the temperance and prohibition campaigns were particularly successful in Protestant societies compared to others and were a significant part of social reform during the Progressive Era.
