Question

    In each of the questions below are given three statements followed by two conclusions numbered I and II. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read both the conclusions and then decide which of given conclusions logically follows from the given  statements disregarding commonly known facts. Give answer

    Statements:                       Some nails are hairs.

                                                    No eye is an ear.

    All hairs are eyes.

    Conclusions:                       I. All nails may be eyes.

                                                    II. Some nails may not be eyes.

    A if both conclusions I and II follow Correct Answer Incorrect Answer
    B if neither conclusion I nor II follows Correct Answer Incorrect Answer
    C if either conclusion I or II follows. Correct Answer Incorrect Answer
    D if only conclusion II follows. Correct Answer Incorrect Answer
    E if only conclusion I follows. Correct Answer Incorrect Answer

    Solution

    For conclusion I, second statement is not required, because we find a common term ‘hair’ in the first and the third statement.  Some nails are hairs (I) + All hairs are eyes (A) = Some nails are eyes (I) ⇒ Probable conclusions ⇒ All nails may be eyes (A) and Some nails may not be eyes(O). Hence, both conclusion I and II follow.
