I want to know the answer to the following question:
In 1913, the Tennessee state legislature made which organizational structure the default form of city government in the state?
All the background I'm provided with is that "In the early 1900s, the state legislature approved a form of commission government for cities based on at-large voting for a few positions on a Board of Commission; several adopted this as another means to limit African-American political participation.". Is that enough to answer the question?
