Please help me with these two questions about the United States' Department of Homeland Security. Thank you so much!

The most recent emergency management systems promote the concept of "tiered response'. Which of the following statements describes what tiered response is? Tiered response refers to preparedness, response and recovery Tiered response is the initial response or first response followed by the near-term response which is then followed b.by the long-term response as the duration of the emergency grows. Oc. Tiered response is simply local, state and federal response operations. Od Tiered response refers to government, non-government and private response operations. There is considerable confusion regarding the National Incident Management System and the incident Command System. The NIMS essentially incorporated (absorbed) and replaced the ICS so they are one-in-the-same and not two separate systems. Is this statement true or false? True False
