Why are senators required to work in at least three committees? they have short terms in office. the senate has a smaller number of members than the house. there are 36 standing committees. the house has a smaller number of members than the senate.

The correct answer is B. An effect of the Lewis and Clark expedition on US business was that it located important routes for trade and travel.

The Lewis and Clark Expedition was the first carried out by Americans who crossed the west of the current United States. The expedition members left San Luis, Missouri, going west and crossed much of North America to reach the Pacific Ocean coast.

The main objective was to explore and map the newly acquired territory of Louisiana, open a safe route through the western half of the continent and establish American presence in the area before Britain or other European powers tried to claim it.
