Explanation:

The Corps of Discovery needed Sacagawea because she could interpret (act as a translator) and guide them through Native American lands. This helped in communication with Native American tribes and navigating unfamiliar territories. The other options: being an expert in botany, a skilled cartographer, or the only woman available were not the primary reasons for her inclusion; her ability to interpret and guide was crucial for the expedition's success in dealing with Native American groups and traversing their lands.

Answer:

She could interpret and guide them through Native American lands
