Which expedition explored the Louisiana Territory, mapping the land and studying plants, animals, and Native American groups?

• A. Sacagawea Expedition
• B. Meriwether Lewis Expedition
• C. Lewis & Clark Expedition
• D. Corps of Discovery

Answer: (C)

This question is about naming the expedition that explored the Louisiana Territory and documented its plants, animals, and Native American groups. The Lewis & Clark Expedition, led by Meriwether Lewis and William Clark from 1804 to 1806, was commissioned to explore and map the land acquired in the Louisiana Purchase and to study natural history and Indigenous peoples. They produced detailed maps and journals describing geography, flora, and fauna, and established relations with many Native American tribes along the way. Sacagawea was a crucial member of the team, but there wasn’t a separate “Sacagawea Expedition”; the journey is commonly known as the Lewis & Clark Expedition, also called the Corps of Discovery, with the formal name matching the description best.
