Final answer:
Having one general government for the 13 colonies would lead to increased decision-making efficiency, better intercolonial coordination, uniform laws, and a stronger defense against external threats.
Step-by-step explanation:
A benefit of having one general government for the whole 13 colonies would be increased efficiency in decision-making. With a central government, the processes and systems would be streamlined, thereby reducing the time and complications associated with having 13 separate governments. This would also lead to better coordination and cooperation among the colonies, as they would work under a unified framework rather than a patchwork of individual regulations and policies. Another significant benefit would be the establishment of uniform laws and regulations across all colonies, which would lead to clear and consistent governance rather than disparate laws that could hamper interstate relations and trade. Lastly, a general government would mean a stronger defense against external threats, as the colonial forces would be unified under one command, making it a more formidable entity to oppose foreign adversaries.
