Expert writing Tips
Best practice
When using "have been complemented", ensure that the context clearly indicates what is being enhanced and what is providing the enhancement. This helps avoid ambiguity and strengthens the clarity of your writing.
Common error
A common mistake is to omit the agent (the entity doing the complementing) when using the passive voice. Always ensure the context makes it clear who or what is providing the complement to avoid confusion. For example instead of writing "The data have been complemented", consider "The data have been complemented by additional research".
