Explanation:

First Question:

In the context of large plantations (especially in colonial America), African slaves were forcibly brought to work on plantations, doing most of the labor. European settlers were more in leadership/ownership roles, and Native Americans were not the primary labor force for large plantations in the relevant historical period.

John Adams defended the British soldiers at the Boston Massacre trial. George Washington was a military leader later, Samuel Adams was a revolutionary leader, and Benjamin Franklin was involved in diplomacy and other aspects, not this trial defense.

After the French & Indian War, France lost its land claims in North America (like territory east of the Mississippi River). Florida was lost by Spain (later to Britain), and Canada was not lost by France in this war (France ceded Canada to Britain? No, actually France lost its North American territories except some small islands, but the main loss was land in America. The option "land in America" is correct. Florida was transferred from Spain to Britain, Canada was ceded by France to Britain? Wait, no—France lost its territory in North America (the vast French - held lands in the interior and east), so "land in America" is the right choice.

Answer:

C. African slaves
