C) Unified Command
D) Preparedness
Answer: A

A) Span of control
B) Supervisor Authority
C) Unified Command
D) Unity of Command
Answer: D
Rationale: Unity of Command means that each person within the incident

A) Increasing span of control to 8:1
B) Decreasing span of control to 2:1
C) Matching an organization's structure to the task
D) The person in charge
