Final answer:
The passage from Nellie Bly's work uses a specific, shocking example to substantiate the author's claim about inhumane asylum conditions.
Step-by-step explanation:
The passage from Ten Days in a Mad-House by Nellie Bly contributes to developing the author's claim by providing a specific and shocking example of the inhumane treatment experienced by patients in the asylum. This anecdote effectively illustrates the severity and the reality of the mistreatment, supporting the author's claim about the deplorable conditions and practices within the institution. The description of the young girl's abuse and subsequent death is a direct and powerful piece of evidence that speaks to the neglect and brutality that were commonplace, making the narrative not just a collection of personal experiences but also a societal criticism and a call for reform.
