Expert writing Tips
Best practice
When using "had not been activated", ensure the context clearly establishes the point in the past to which you're referring. This helps avoid ambiguity about when the activation was expected but didn't occur.
Common error
Avoid confusing "had not been activated" with simpler tenses like "was not activated". The past perfect construction ("had been") implies a sequence of events, where one action occurred before another specified point in the past. Use the simple past passive ("was not activated") if you're only describing a single event in the past with no relation to a later event.
