Which of the following is NOT considered a challenge faced by modern prisons?

The option indicating "unlimited resources" is correct because modern prisons typically operate under significant constraints and challenges, including budget limitations and resource scarcity. Unlike the implication of having unlimited resources, which suggests that prisons could easily address issues like overcrowding, legal challenges, or racial conflicts, the reality is that many facilities struggle with insufficient funding. This leads to problems such as inadequate staffing, limited healthcare services, and insufficient programs for rehabilitation.

In contrast, challenges such as racial conflicts, legal issues, and overcrowding are real and pressing concerns within the corrections system. Racial tensions can arise from systemic inequalities and the demographics of incarceration. Legal issues often pertain to the rights of inmates, lawsuits, and compliance with court mandates. Overcrowding is pervasive, leading to unsafe conditions and strained resources. Each of these aspects contributes to the difficulties that modern prisons face, making the notion of "unlimited resources" unrealistic in the context of today's correctional facilities.
