Please Help Me with this what was one goal of the lewis and Clark expedition?

A .to learn about the wildlife of the Louisiana territory
B .to report conflicts among American Indians in the west
C . to show that the route to the west was not dangerous
D .to search for gold in the Louisiana territory.

        i'm fairly sure that the correct answers are 2 and 3.

        i used both my knowledge of world history and the process of elimination to obtain these answers. option 1 cannot be a possible selection because the mandate of heaven belongs to ancient chinese philosophical belief. option 4 sounds like it would benefit the region than detriment it. however, both 2 and 3 explain a potential reason for what could have contributed to the fall of the roman empire.

      hope this ! if i were you, i'd get a second opinion, because i haven't taken this course for a year. best of luck!
