Final answer:
The highest priority for Progressive reform in city government was to combat urban corruption through merit-based governance and the creation of welfare programs.
Step-by-step explanation:
Progressive reform at the level of city government seemed to indicate that the progressives' highest priority was addressing urban corruption and implementing merit-based governance. Progressives aimed to dismantle the control of political machines by introducing systems like the commissioner and city-manager models of governance, where officials were selected based on expertise rather than political favors. They strove for more efficient, less corrupt city management and the creation of social welfare programs to enhance the quality of urban life. Cities managed utilities to end monopolies and ensure affordable services, and also supported welfare services such as work relief, parks, and schools.
