Why did Lewis and Clark find a path to the Pacific Ocean?

The correct answer is: To explore the land of Louisiana Purchase and establish trade relations with Native Americans

In 1803, President Thomas Jefferson brokered the Louisiana Purchase deal to buy 828,000 acres of land, doubling the size of the US overnight. Jefferson was curious about all this newly acquired land—what animals lived there, where the rivers flowed, the best way to get from here to there—so commissioned the young frontiersmen Meriwether Lewis and William Clark to lead a crew of soldiers on a three-year exploration trip.
