Step-by-step explanation:
The Corps of Discovery was a specially-established unit of the United States Army which formed the nucleus of the Lewis and Clark Expedition that took place between May 1804 and September 1806. The Corps was led jointly by Captain Meriwether Lewis and Second Lieutenant William Clark. Commissioned by President Thomas Jefferson, the Corps' objectives were scientific and commercial – to study the area's plants, animal life, and geography, and to learn how the Louisiana Purchase could be exploited economically.[1] An additional group of scouts, boatmen, and civilians aided the Corps.
