Question

most of lewis and clark’s expedition took place on the _______. a great plains b missouri river c columbia river d mississippi river

Explanation:

The Lewis and Clark Expedition (1804–1806) aimed to explore the newly acquired Louisiana Territory. Most of their journey was along the Missouri River as they traveled westward, using it as a primary waterway for navigation and exploration. The Great Plains is a land region, the Columbia River was part of the later western leg, and the Mississippi River was their starting point (but not where most of the expedition took place). So the correct answer relates to the Missouri River.

Answer:

B. Missouri River
