Expert writing Tips
Best practice
Consider replacing "is present by" with a more direct and active construction for clarity. For example, instead of "the effect is present by this method", try "this method produces the effect".
Common error
Avoid using "is present by" when a more active voice would be clearer and more concise. Passive voice can obscure the agent performing the action, so opt for active voice when the agent is known and relevant.
