Expert writing Tips
Best practice
When using "were indistinguishable", ensure that the context clearly defines the aspects in which the subjects are not distinguishable. For instance, specify if they "were indistinguishable in terms of taste" or "were indistinguishable visually."
Common error
Avoid using "were indistinguishable" without providing specific details about what aspects lack distinction. Saying "the two options were indistinguishable" without specifying the criteria (e.g., price, quality, features) leaves the statement vague and less informative.
