The United States wanted the Lousiana Territory to gain control of commerce on the Mississippi River. The Lousiana Territory was formerly owned by Spain. Spain made a treaty with Napoleon and gave the territory to him. President Jefferson wanted that territory for America and purchased it from Napoleon in 15 million dollars. The Lousiana Territory became American Territory.

i think the answer is the one about environmental and social health.

hope this
