Final answer:
Parliament raising taxes on those moving west was not an issue before the French & Indian War; issues were crossing the Appalachians, French claims, and Native American inhabitants.
Step-by-step explanation:
The issue that was NOT a problem for the colonists moving west before the French & Indian War was Parliament raising taxes on those who moved west. Before the war, Parliament had not yet imposed such taxes on western expansion. The real issues that colonists faced included crossing the Appalachian Mountains, which was a significant physical barrier; dealing with the fact that some of the land was claimed by France, which contested British colonial expansion; and acknowledging that Native Americans lived on the land, leading to conflicts on the western frontier. It was only after the war, with the Proclamation of 1763, that the British government attempted to limit westward expansion to avoid conflicts with Native Americans and assert greater control over the colonies, in part through taxing.
