Who among the following was a moderate delegate from Pennsylvania during the Continental Congress?

The correct answer is John Dickinson. He was known for his moderate stance during the Continental Congress, advocating a position of reconciliation with Britain as opposed to immediate independence. As a delegate from Pennsylvania, Dickinson argued for the rights of the colonies but sought to avoid outright conflict. His notable contributions included drafting the "Olive Branch Petition," which was an appeal to King George III to address colonial grievances while still attempting to maintain a connection with Britain.

John Adams and Samuel Adams, in contrast, were more radical figures who pushed for independence and were deeply involved in the revolutionary movement. John Jay, while also a significant figure in the early governmental structure, was part of the faction that leaned towards independence but did not have the same moderate reputation as Dickinson during this period. Thus, Dickinson stands out as the moderate voice within the context of the Continental Congress.
