Final answer:
Jefferson asked Congress to provide for a temporary government in the new territory to address immediate needs and work towards establishing a stable nation.
Step-by-step explanation:
President Jefferson asked Congress to provide for a temporary government in the new territory because the formation of new republics was seen as an integral part of the move towards independence. Additionally, the necessities of war prompted the need for an established body to help maintain order, tax the citizens, staff the militia, and ensure public safety. By creating a temporary government, Jefferson aimed to address these immediate needs while also working towards the long-term goal of establishing a stable and functioning nation.
