Question

how did the lewis and clark expedition impact the plateau tribes?
it brought potatoes to the plateau, encouraging them to start agricultural settlements.
it increased the number of white settlers coming to the region, leading to deadly epidemics.
it introduced horses to the plateau tribes for the first time, revolutionizing hunting and travel.

Explanation:

To determine the correct answer, we analyze each option:

• The first option about potatoes is incorrect as the Lewis and Clark Expedition's impact on Plateau tribes wasn't centered around introducing potatoes for agricultural settlements.
• The second option states that the expedition increased white settlers, leading to deadly epidemics. Historical context shows that the expedition's reports and findings spurred more white settlement, which brought diseases like smallpox that devastated Native populations, matching the scenario described in the text.
• The third option about introducing horses is incorrect because horses were already present in the region before the Lewis and Clark Expedition (brought by earlier Spanish explorers, for example).

Answer:

B. It increased the number of white settlers coming to the region, leading to deadly epidemics.
