What is the author’s purpose for writing, as demonstrated by this passage? How does the author’s viewpoint support this purpose?

This question seems incomplete. Here is the possible full question:

Lying down was not an option, nor could we all sit down. We decide to take turns sitting. There was little air. The lucky ones found themselves near the window; they could watch the blooming countryside. After two days travel, thirst became intolerable, as did the heat. There was still some food left. But we never ate enough to satisfy our hunger. Our principle was to economize, to save for tomorrow. Tomorrow could be worse yet.
