Final answer:
The request in front of the hospital represents both the physical healing of individuals and the societal healing desired during the Iranian Revolution. It emphasizes the opposition to the Shah's regime and the significant unrest because of the U.S. allowing the Shah in for medical treatment.
Step-by-step explanation:
In front of the hospital, the Iranian people are requested to face a critical choice in the conflict between conservative Islamic fundamentalists and Islamic reformers. This request has a double meaning as it underscores the physical healing during a time of turmoil and the broader societal healing and transformation sought by protestors against the current regime. The latter meaning connects to the wider context of the Iranian Revolution, where the people opposed the Shah's regime, reacted to the Shah being allowed into the U.S. for medical treatment, and demanded his return for trial and potential execution.
