Final answer:
William Penn's elected assembly provided a model for representative government and religious freedom, directly influencing the U.S. government's creation.
Step-by-step explanation:
William Penn’s elected assembly had a significant impact on the creation of the United States government. The democratic principles and structures of government that Penn introduced, such as the first "Frame of Government", the third "Frame of Government", and the "Charter of Privileges", provided a model for representative government and religious freedom. These elements directly influenced the framers of the U.S. Constitution and the overall republican form of government that was established after the American Revolution. The representative assembly that Penn established offered more control to the colonists and emphasized the consent of the governed, paving the way for similar structures in the new nation.
