In regards to processing incidents, which facilities must be open during large-scale events?

The correct answer emphasizes the importance of maintaining operational readiness and support during large-scale events, particularly through Port Authority Facilities. These facilities are vital because they typically manage significant transportation hubs, such as airports and bus terminals, which can experience high volumes of traffic and activity during large events. Keeping these facilities open ensures that emergency planning, crowd control, and transportation logistics can be effectively managed.

Further, Port Authority Facilities play a critical role in coordinating response efforts with law enforcement and emergency services. Their strategic locations and resources can support the overall safety and flow of people during events where crowd management is crucial. This operational capability is not necessarily the same for the other choices, which may not have the same scale of logistical and emergency impact during large gatherings.
