Question

which quote from \my heart is bursting\ best summarizes the message of settainte (satanta)s speech?
all of the land south of the arkansas belongs to the kiowas and the comanches, and i dont want to give away any of it.
i want you to understand well what i say. write it on paper.
i have heard that you intend to settle us on a reservation near the mountains.
a long time ago this land belonged to our fathers; but when i go up to the river i see camps of soldiers on its banks.

Explanation:

Satanta's speech in My Heart Is Bursting centers on asserting the Kiowa and Comanche claim to their ancestral land and refusing to surrender it. The correct quote directly states this core message, while the others are either a request for documentation, a statement of hearing the U.S. government's plan, or an observation of military presence, not the overarching message.

Answer:

All of the land south of the Arkansas belongs to the Kiowas and the Comanches, and I don't want to give away any of it.
