Crisis management refers to how the government handles and responds to a sudden event after it erupts. Crisis management is more comprehensive and includes not only methods for dealing with crisis outbreaks, durations and recessions, but even treatments for latency periods. When the crisis has not yet occurred, the government should have an early warning capability, and then the ability to deal with the crisis. According to this text, the correct one is:. ['Crisis management is more critical.', 'Crisis management includes crisis management.', 'Crisis management is at the core of crisis management.', 'Crisis management can prevent crisis events.']
