Range command 'Unload' moves from which conditions to Condition 4?

• A. Condition 3 to Condition 1
• B. Condition 1 or 3 to Condition 4
• C. Condition 4 to Condition 1
• D. Condition 2 to Condition 4

Answer: (B)

Understanding state transitions in the Range command: the Unload action moves the system into Condition 4 only from prior states where unloading is allowed, specifically Condition 1 or Condition 3. These states represent moments where it’s appropriate to finalize and switch to the unloaded state. If the system is in Condition 2, it isn’t in a ready position to unload, so moving directly to Condition 4 isn’t permitted. If it’s already in Condition 4, there’s no transition to make. So the only valid paths into Condition 4 come from Condition 1 or Condition 3.
