Final answer:
The Proprietary Party did include the Penn family and their agents, making the statement true. Proprietors had many responsibilities, not just profit collection, so that claim is false. And Pennsylvania's constitution during the Revolutionary Era was progressive, not conservative.
Step-by-step explanation:
The statement that the Proprietary Party consisted of the Penn's family and agents is true. In a proprietary colony like Pennsylvania, the proprietors had numerous responsibilities beyond just collecting profits. They governed the colony, enacted laws, and were responsible for the well-being and growth of their territory. Thus, the statement that proprietors have no responsibilities except to collect the profits is false.
Pennsylvania, indeed, adopted a progressive and liberal constitution during the Revolutionary Era, not a conservative one. Therefore, the statement that Pennsylvania adopted one of the most conservative constitutions of the Revolutionary Era is false.
