Answer:
The part of the passage where it was revealed that "Republican-led US Congress was unlikely to admit a heavily Democratic Indian Territory."
Step-by-step explanation:
In the early twentieth century specifically, 1905, when the goal of the Sequoyah Convention was to draft a constitution for a proposed single state made from the Indian Territory.
The then United States Congress which is being led or has a majority of Republicans, therey felt that the ideas and principles of these Native Indians will not align with their own ideologies, hence the United States Congress at the time eventually declined to consider statehood for the state of Sequoyah
