Final answer:
I provided a general response on character analysis, discussing traits, motivations, and interactions in a narrative. The original references did not match the characters mentioned, hence the more generalized approach to character description and believability.
Step-by-step explanation:
It seems there's a mix-up in the reference texts provided versus the characters mentioned. Sue, Johnsy, and Behrman are not characters from the provided texts. However, I'll provide a general response on character analysis.
When describing characters like Sue, Johnsy, and Behrman, one would look into their traits, motivations, and how they interact with the story's world. For instance, a character could be determined, showing persistence despite challenges. Alternatively, a character might be kind-hearted, often putting others' needs before their own. These qualities would help in understanding their role within the narrative. In terms of believability, one might consider whether the characters act in ways that are consistent with their established traits, or if they undergo development that justifies changes in their behavior.
When determining if characters are stereotypes, analysis of their actions, dialogues, and author's intent would be crucial. If they embody oversimplified and widely held images of a group, they might be considered stereotypes.
