What are two reasons why the united states government sent expeditions into the louisiana territory in the 1800s?

They wanted to know more about the geography, land, resources, people, and cultures there. The correct answer is "At that time, Americans knew very little about the geography of the area." and "The government wanted to establish friendly ties with American Indians there."

its main object was the establishment of "settlement houses" in poor urban areas, in which volunteer middle-class "settlement workers" would live, hoping to share knowledge and culture with, and alleviate the poverty of, their low-income neighbors.
