Passage: "When the municipal hall introduced a queue-number system, complaints about long waits dropped sharply. Clients no longer had to stand in line for hours; they could sit, watch a screen and wait for their number. Staff also noticed fewer arguments at the counters. The only problem arose when the system broke down during a power interruption, so the office now keeps printed numbers as a backup." Which title best fits the passage?
Correct answer: C. A Simple Change That Shortened the Wait
The passage is about how a queue-number system reduced complaints and arguments, with a note on a backup plan. The first title captures this; the third focuses on only a minor detail.
