Which of the following is an example of office equipment failure?

• A. Power supply failure
• B. Worn-out bearings
• C. Brake failure
• D. Pump failure

Answer: (A)

A core idea here is recognizing what kinds of failures happen to typical office devices. Office equipment depends on a stable electrical supply to run computers, printers, and similar gear. When the power supply fails, the device cannot power on or may shut down unexpectedly, which is a common and familiar issue in an office setting.

The other failures involve mechanical components found in machines, vehicles, or industrial equipment rather than everyday office gear. Worn-out bearings are about rotating machinery; brake failure relates to stopping mechanisms; pump failure concerns moving fluids in industrial systems. These don’t describe standard office devices, so they’re not examples of office equipment failure.
