PLZS HELP - By secret treaty during the French and Indian War (1755–63) the French transferred Louisiana to Spain in 1762. The acquisition made Spain the controlling authority over the Mississippi River to its origins. Louisiana remained under Spanish rule until 1800, during which time it prospered, witnessing the germination of the vibrant cultural and artistic life for which the state is still known. . . . In a 1795 treaty with Spain, the United States obtained rights to navigate the Mississippi River and use the port of New Orleans as a place of deposit for American commodities and transshipment on oceangoing vessels. –Louisiana: European Explorations and the Louisiana Purchase, Michael Klein What is the text structure of this passage?
