Read the excerpt from part 2 of Zeitoun. As he paddled back to Claiborne, a hope flickered within Zeitoun that his siblings might see him on TV. Perhaps they would see what he was doing, that he had done something good by staying in his adopted city. The Zeitouns were proud, and there was plenty of sibling rivalry that had pushed them all to an array of achievements—all of them measured against the deeds of Mohammed. None of them had ever done something like that, none had achieved on his level. But Zeitoun felt again that perhaps this was his calling, that God had waited to put him here and now to test him in this way. And so he hoped, as silly as it seemed, that his siblings might see him like this.

Why does the author include Zeitoun’s thoughts?
to emphasize how his Muslim faith drives his actions
to illustrate how his strong familial bonds comfort him
to establish the way he competes with his siblings
to reveal the vain hopes held by Katrina survivors
