    Question

    In the question below there are three statements

    followed by two conclusions I and II. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts. Statements: All valid are proof. All proofs are identity. None of the identity are card. Conclusions: I. Some proofs are not card. II. No identity is valid.
    A Only conclusion I follows Correct Answer Incorrect Answer
    B Only conclusion II follows Correct Answer Incorrect Answer
    C Neither conclusion I nor conclusion II follows Correct Answer Incorrect Answer
    D Both conclusion I and conclusion II follow Correct Answer Incorrect Answer

    Solution

    All proofs are identity (A) + None of the identity are card (E) → No proof is a card (E) → Conversion →   No card is a proof (E) → Conversion →    Some proofs are not card (O). Hence conclusion I follows. All valid are proof (A) + All proofs are identity (A) → All valid are identity (A). Hence conclusion II does not follow.
