Airbags reserve energy supply lasts anywhere from _____ to _____ minutes.

Airbags reserve energy supply lasts anywhere from _____ to _____ minutes.

• A. 1 to 30
• B. 2 to 60
• C. 5 to 15
• D. 2 to 60

Answer: (D)

The idea being tested is how long a backup energy source can keep the airbag system functional during a power loss. This reserve isn’t about immediate deployment alone; it must sustain essential functions—like sensors, control electronics, and communications—until the situation is resolved or help arrives. A duration of a couple of minutes is enough to ensure the system remains ready during the initial response, but some installations need longer standby time, up to about an hour, to cover extended emergencies or maintenance scenarios. That broader range explains why the answer spans from around 2 to 60 minutes: it accommodates the variability in different designs and operating conditions. Shorter ranges don’t fit all systems, while the 2–60 window reflects the typical spectrum of backup endurance across implementations.
