Expert writing Tips
Best practice
When using "is not produced", ensure the context clearly indicates what entity or process is responsible for the potential production. For example, "This effect is not produced by the new software." clarifies that the software is not the cause.
Common error
Avoid ambiguity by specifying what 'is not producing' something. Without context, "is not produced" can leave the reader wondering about the responsible agent. For example, clarify 'The data is not produced by this method' instead of simply stating 'The data is not produced'.
