Expert writing Tips
Best practice
When using "have been prevented", ensure the context clearly indicates what actions or measures led to the prevention. This provides a clearer understanding of the cause-and-effect relationship.
Common error
Avoid using the active voice when the passive voice is more appropriate. Instead of saying "They have prevented the accident", which focuses on the actors, using "The accident could "have been prevented"" places the emphasis on the event and the possibility of its avoidance.
