How does the relationship between a task and a purpose appear in an order?

• A. A task explains why it is being done.
• B. The purpose is a broader directive that replaces the task.
• C. A task is what to do; the purpose explains why it is being done.
• D. The task is when to act.

Answer: (C)

In an order, the action required and the reason behind it are linked: the task tells you what to do, and the purpose explains why it is being done. This pairing makes the intent clear so you can execute the action with the right end in mind, and adapt if conditions change while staying aligned with the overall objective. The best choice expresses that dynamic: a task is what to do; the purpose explains why it is being done. For example, task: secure the bridge; purpose: to allow friendly forces to move across and disrupt enemy reinforcement. The purpose isn’t replacing the task, and it's not about timing or explaining why the task is needed in place of the action.
