Final answer:
If the 13 original states had not allowed new states to be formed, the country would have been more fragmented and less unified, leading to greater regional conflicts. The population distribution would have been more uneven, and economic development would have been slower.
Step-by-step explanation:
If the 13 original states had carved up the remaining lands for themselves instead of allowing new states to be formed, several things would have been different. First, the country would have been more fragmented and less unified because each state would have been focused on its own interests rather than working together as a whole. This could have led to greater regional conflicts as states competed for resources and influence. Additionally, the population distribution would have been more uneven, with some states becoming heavily populated while others would have remained sparsely populated. Finally, economic development would have been slower because each state would have been responsible for its own economic growth without the benefits of collaboration and shared resources.
