The Holy People in Navajo sacred narratives do not act as _____ when they teach; it is as often by what they do wrong as by what they do right.

The term "agents" implies that the Holy People actively participate in the world and influence events. This accurately describes their role in Navajo narratives, as they engage with the world and its inhabitants to convey teachings through their actions.

"Arbiters" suggests that the Holy People make judgments or decisions, often serving as mediators between different parties. In the context of Navajo teachings, they may play a role in resolving conflicts, but this does not encompass the entirety of their function as educators in the narratives.

The word "defenders" indicates a protective role, where the Holy People might advocate for or safeguard others. While they can embody protective qualities, this term does not encapsulate their broader role as teachers who convey lessons through their experiences.

Ethicists are concerned with moral principles and values. The Holy People do teach moral lessons, but they are not strictly moral philosophers; rather, they are figures from whom people learn through their varied experiences, both commendable and questionable.

"Exemplars" refers to those who serve as models of good behavior or excellence. While the Holy People can demonstrate positive actions, they are not consistently portrayed as flawless, which contrasts with the ideal of being exemplars.
