Explanation:

President Thomas Jefferson commissioned the expedition after the Louisiana Purchase in 1803 to explore and to map the newly acquired territory, to find a practical route across the western half of the continent, and to establish an American presence in this territory before Britain and other European powers tried to claim it. Also the objectives were scientific and economic: to study the area's plants, animal life, and geography, and to establish trade with local American Indian tribes.

explanation:

actually, not all representation was acceptable based on this little piece of article, in 1776, the second continental congress issued the declaration of independence, stating their specific grievances with the british monarchy and why they were going to create a separate government. after the colonies separated from the british monarchy and formed the united states of america, they had to answer some crucial questions: 1) if not a monarchy, what type of government was the united states going to have? 2) what kind of government was going to protect the people without violating their individual liberties?

this doesn't support enough information to answer the question.
