Analyze any conjunctive conditional syllogism in four steps:
1. Classify each whole premise as categorical, connected, or disjunctive.
2. Locate the common part as antecedent, consequent, subject, or predicate.
3. Check quality, quantity, and the exact conditional or alternative relationship.
4. State only the conclusion actually entailed by those premises.
A useful validity test is whether the premises could all be true while the proposed conclusion is false. If so, the inference needs correction.
