A factory installs sensors to detect faults in advance. Which technological benefit does this show?

Correct answer: Predictive maintenance

The governing concept is the use of technology to monitor operations and prevent failures before they interrupt production. Sensors continuously collect information such as temperature, vibration, pressure, or unusual movement. When the information indicates a likely fault, the factory can inspect or repair the machine before a breakdown occurs. This is predictive maintenance, making option A correct. A festival in the market, a government election, and a family tradition are social or political circumstances, not technological benefits of factory monitoring. The word “in advance” is the key clue: the system predicts or detects a problem early instead of waiting for the machine to stop.
