Expert writing Tips
Best practice
Use "was occurring" to describe an event that was in progress at a specific point in the past. This emphasizes the duration or ongoing nature of the event.
Common error
Avoid using the simple past tense (e.g., "occurred") when you want to emphasize the continuous nature of an event in the past. "Occurred" simply states that something happened; "was occurring" highlights that it was in progress.
