Question

    Read the given statements and conclusions carefully.

    Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statements: Some Flowers are Leaves. All Flowers are Stems. No leaf is Petal. Conclusion: I. No Flower is Petal. II. Some Stems are Leaves. III. Some Stems are not Petals.
    A Only conclusion III follows. Correct Answer Incorrect Answer
    B Only conclusions II and III follow. Correct Answer Incorrect Answer
    C Only conclusions I and III follow. Correct Answer Incorrect Answer
    D All the conclusions follow Correct Answer Incorrect Answer

    Solution

    Some Flowers are Leaves (I) + No leaf is Petal (E) → Some Flowers are not Petals (O). Hence conclusion I does not follow. Some Flowers are Leaves (I) → Conversion → Some Leaves are Flowers (I) + All Flowers are Stems (I) → Some Leaves are Stems (I) → Conversion → Some Stems are Leaves (I). Hence conclusion II follows. Some Stems are Leaves (I) + No leaf is Petal (E) → Some Stems are not Petals (O). Hence conclusion III follows.
