Explanation:

The problem relates to a historical treaty and Senate debate, which falls under the Social Science discipline, specifically History (or Politics, as treaties involve political processes). The context is about a treaty needing Senate ratification (a key political/historical concept) and prompting debate about its terms or implications.

Answer:

The treaty needed Senate ratification to take effect and prompted debate about its terms (or U.S. involvement in international affairs, e.g., League of Nations for Treaty of Versailles context).

(Note: If this is about the Treaty of Versailles and League of Nations, the debate was about U.S. participation in the League. The map likely shows regions related to the treaty’s scope, but the fill - in is about Senate ratification and debate over U.S. involvement in international organizations/treaty obligations.)
