Which individual served as a guide for the Lewis and Clark expedition?

• A. Sacajawea
• B. Pocahontas
• C. Betsy Ross
• D. Harriet Tubman

Answer: (A)

The idea being tested is recognizing Sacagawea as a guide and interpreter for the Lewis and Clark expedition. She was a Shoshone woman who joined the corps of discovery with her husband, serving as both translator and guide. Her knowledge of the land, plants, and local tribes helped the expedition navigate unfamiliar terrain, find edible resources, and communicate effectively with Native American groups they encountered. Importantly, she helped secure horses from the Shoshone to cross the Rocky Mountains, a vital step in reaching the Pacific. Her presence with a child also signaled peaceful intentions to tribes who might otherwise be wary, easing diplomacy along the way. The other figures are known for different historical roles and contexts, not for guiding Lewis and Clark.
