To answer the question, you would need to analyze the specific excerpt from the article about Nellie Bly to determine which idea is best supported by the evidence presented. Without the actual excerpt, I can't provide a definitive answer.
However, if the excerpt describes psychiatrists showing indifference to patients or treating them poorly, it would support the first response. If the excerpt indicates that psychiatrists were aware of Bly's investigation and were attempting to conceal their practices, it would support the second or third response. If it emphasizes the high patient volume leading to neglect of individual care, that would support the fourth response.
Please provide the excerpt or key details if you want a more precise analysis.
