Your sorting machine has just completed processing a tray of mail. You notice a few pieces appear to have been sorted incorrectly. What is the BEST action?

Mis-sorts caught at the processing stage can be corrected BEFORE causing downstream problems (delayed delivery, returned mail, customer complaints). The exam is testing whether you: (1) RECOGNIZE the error rather than ignoring it; (2) RECOVER and CORRECT — manually re-sort with proper destinations; (3) CHECK ROOT CAUSE — single mis-sorts can be random; patterns indicate machine calibration, alignment, or sensor problems requiring maintenance; (4) ESCALATE patterns for systematic correction. Ignoring fails because the mis-sorts become customer-service problems. Adding to a random tray makes the error worse. Throwing away is a serious offense. The right response: catch + correct + check root cause + escalate when needed. This is exactly the quality-control thinking USPS needs in mail processing.
