Final answer:
The Populists advocated for more citizen involvement in governance through democratic reforms such as initiatives, referendums, and recall processes to foster direct democracy.
Step-by-step explanation:
The best conclusion supported by the paragraph about the Populists from the section "Birth of the Populists" is that Populists wanted people to be more involved in the political process. This is evidenced by their demands for democratic reforms that would enable more direct citizen participation in governance, such as the initiative, referendum, and recall processes which allow citizens to propose and vote on laws directly, as well as the secret ballot and a one-term limit for the president. These reforms indicate a clear desire to increase direct democratic engagement and diminish the gap between elected officials and their constituents.
