Final answer:
The statement that Civil War in England prevented William Penn from returning to Pennsylvania is false, as are claims about Pennsylvania's constitution being conservative and colonial self-sufficiency regarding British goods.
Step-by-step explanation:
The statement 'Civil War in England kept Penn from travelling back to PA' is false. William Penn, the founder of Pennsylvania, lived during the 17th century, and his difficulties in traveling back to Pennsylvania were not due to the English Civil War, which occurred from 1642-1651, but rather to various political and financial troubles he faced in England later on. This statement is a bit of an anachronism, as Penn's issues with traveling occurred after the civil war had ended.
Regarding the other statements provided: Pennsylvania adopted one of the most conservative constitutions of the Revolutionary Era is also false. The constitution adopted by Pennsylvania was actually one of the more radical ones at that time. As for the notion that most colonists in eighteenth century North America were largely self-sufficient and did not need to import consumer goods from Britain, this is also false. Colonists were indeed reliant on British goods, and the trade relationships between the colonies and Britain were significant.
