Before (weak and unclear):
“Reviewer 2 asked us to add more background. We don’t think it is necessary, but we added a sentence.”
After (professional and verifiable):
“Thank you for this helpful suggestion. To improve context, we expanded the background discussion in the Introduction (Page 2, Lines 41–58) and added two relevant references. This revision clarifies the motivation for our approach and better positions the study within existing work.”
