Answer: D) It depicts how the Kiowas are connected to the land and traveling.
Explanation: In the given excerpt about the Kiowas, we can see that they are summer people, they don't travel when the weather is cold, but when the summer arrive they start to travel, because they love to do that. This passage develops the central idea by explaining how the Kiowas are connected to the land and traveling ("but when the season turns and the land becomes warm and vital they cannot hold still").
You didn't include the answer choices, but a question with the same wording popped up on the quiz I just took and the answer for me was B : They suspect something strange may be going on.
