Answer
Correct Answer: No improvement
Explanation
Given sentence'You are warned against committing the same mistake again.'
Concept/ApproachAfter 'warn against', use a gerund: 'against committing'. The sentence is concise and idiomatic.
Why alternatives are incorrect'to commit' → wrong structure after 'against'.'for committing' → changes meaning (sounds like 'punished for').'against to commit' → ungrammatical double marker.
Final AnswerNo improvement
