I found out a strategy to attack CR questions but not able to apply it to all questions.

CPA Strategy- Conclusion - Proof - Assumption.

Conclusion and Proof are always there in the argument. Easy to comprehend. But problem lies in finding Assumption(which is not stated). Whenever i start thinking what assumption could be, i end up stating the proof.

Now is there a method to isolate proof and conclusion so that i can go towards finding assumption. Because once Assumption is found, then it's easy to crack the CR question.
