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: All Needle are Thread. No Thread is Shirt. Some Shirt are Button. Conclusions: I. Some Needle are Button. II. No Thread is Button III. No Needle is Shirt.
    A Only conclusion II follows Correct Answer Incorrect Answer
    B Only conclusions I and II follow Correct Answer Incorrect Answer
    C Only conclusion III follows Correct Answer Incorrect Answer
    D Only conclusions I and III follow Correct Answer Incorrect Answer

    Solution

    All Needle are Thread (A) + No Thread is Shirt (E) → No Needle is Shirt (E) + Some Shirt are Button (I) → Some Button are not Needle (O*). Hence conclusion I does not follow but conclusion III follows. No Thread is Shirt (E) + Some Shirt are Button (I) → Some Button are not Thread (O*). Hence conclusion II does not follow.
