Answer: A. the importance of speaking passionately and honestly.
Step-by-step explanation:
The Nez Perce is a tribe that has settled on the Columbia River Plateau in the Pacific Northwest region, and has lived there for around 11,500 years.
In this excerpt from "An Indian's View of Indian Affairs", they are described as speaking passionately ("from my heart"), and honestly ("with a straight tongue"). Sharing valued tradition with others is not mentioned, hence the option B is incorrect. Option C only partially conveys what is being said in the excerpt, as they do not only state whatever is on their minds, but speak passionately as well. Option D is incorrect, because the Nez Perce are portrayed as honest and they do not choose their words carefully. Finally, the only option that encompasses the whole idea presented in the excerpt is option A.
