PASS if the answer traces the 23 support contacts to customers being unable to tell which rental they are extending, citing the look-alike rows and the dialog's missing rental identity and current return date, and does not claim that a wrong rental was ever extended.
FAIL if it attributes those contacts to a backend defect, claims wrong rentals were extended, or gives a generic usability diagnosis not tied to the supplied evidence.
