Expert writing Tips
Best practice
When referring to a completed task or event related to a performance, ensure the subject-verb agreement is correct. Use "performance has been done" only when referring to a singular performance. Otherwise, "performances have been done" is the correct form, although rewriting the sentence for clarity is preferable.
Common error
Avoid using "performance have been done" when referring to a single performance. The correct form is "performance has been done". For multiple performances, use "performances have been done" or, better, rephrase for clarity.
