Final answer:
The ratification of the Constitution seemed unsettled after nine states approved it due to resistance from large states like New York and Virginia over the absence of a bill of rights. The Federalists agreed to consider amendments to appease these states, addressing fears of a tyrannical central government.
Step-by-step explanation:
Even after nine states ratified the Constitution, the issue of ratification remained unsettled largely due to the resistance from some of the more populous and influential states. New York and Virginia, in particular, had strong objections to the Constitution's lack of a bill of rights.
The debate in Virginia exemplifies how critical the issue was. Despite having the technical number of ratifications needed to enact the Constitution, the close and contentious vote in Virginia meant that its decision carried much weight for the legitimacy and future of the nation.
