Please be patient, Channy-Boo.

You tell us. What did the Lewis and Clark Expedition do?

Well they set out upon a great journey across the previously purchased Louisiana Territory. Though they had set off in 1804,but didn't return from their expedition until September 23, 1806. Toussaint's wife, was a Shoshone know as Sacagawea. Sacagawea helped to interpret when the expedition came across Shoshone indians..

Why did they go on this expedition?

Sacagawea is irrelevant to your question.

Oh okay, well they went on their expedition was to explore the Missouri River.

Why? Who sent them? What were the reasons for their explorations?

President Jefferson sent them.The expedition was to learn more about the Northwest's natural resources, inhabitants, and possibilities for settlement

Yay! You're right.

:-)

So that's the answer to my problem?
