(02.05 mc)what was the significance of pinckney's treaty? it created a territory in an area still claimed by great britain. it settled disputes with great britain over military outposts. it created new conflicts with spain over trade on the mississippi river. it settled border and trade disputes with spain in north america.

(D) is the most correct answer. Pinckney's Treaty, also known as the Treaty of San Lorenzo, gave the US shipping rights on the Mississippi River and transport through New Orleans. The problem, at the time, was that even though the Mississippi River was under US control, the southern part was claimed by the Spanish. This led to a border dispute: Pinckney, then the minister to Great Britain, was the creator of the treaty that resolved this dispute in the late 1790s.
