What portion of the crew should be replaced at one time to allow new workers to acclimate to the plan and tactics?

• A. Segment
• B. Portion
• C. Part
• D. Section

Answer: (C)

Rotating a part of the crew at one time keeps the operation moving while giving new workers a chance to learn and acclimate to the plan and tactics. Having a defined part of the crew cycle out allows the newcomers to observe, apply instruction under supervision, and gradually build familiarity without losing continuity or overwhelming the team. This approach also supports safety, because the remaining experienced members maintain stability in supervision and execution, while mentors guide the fresh hands.

A segment or section tends to imply larger, fixed blocks of personnel, which can disrupt continuity if rotated. A portion is a bit more generic, whereas a part communicates a clearly intended, manageable subset that can be rotated without dismantling the overall team structure.
