Expert writing Tips

Best practice

Always use the correct grammatical form, such as "it is demonstrated by" or "it demonstrates", to ensure clarity and accuracy in your writing.

Common error

Ensure you include the auxiliary verb (e.g., "is", "was", "has been") before "demonstrated" to create a complete and grammatically correct passive voice construction. Omitting the auxiliary verb results in an ungrammatical phrase.
