Final answer:
Elie may wish to keep his gold tooth for financial security, identity purposes, or as a remnant of normal life; while Franek's technique to obtain it likely involves force or intimidation.
Step-by-step explanation:
The question pertains to Elie Wiesel's desire to keep his gold tooth in the narrative. Elie may want to hold onto his gold tooth for multiple reasons such as a form of asset, personal reasons related to sense of self and identity, or simply because it represents a small piece of normalcy in inhumane conditions. The technique Franek uses to acquire the tooth likely involves coercion, manipulation, or threats, which would reflect the power dynamics and harsh survivalist environment in the setting of the story.
