    Question

    In each of the questions below. Some statements are given followed by conclusions/group of conclusions numbered I and II. You have to assume all the statements to be true even if they seem to be at variance from the commonly known facts and then decide which of the given two conclusions logically follows from the information given in the statements.

    Statements: All Light are Pole Some

    Steel is Light No Pole is Metal Conclusions: I. All Metal is being Light is a possibility II. All Pole is being Steel is a possibility
    A only conclusion I follows Correct Answer Incorrect Answer
    B If only conclusion II follows Correct Answer Incorrect Answer
    C If either I or II follows Correct Answer Incorrect Answer
    D If neither I nor II follows Correct Answer Incorrect Answer
    E If both I and II follow Correct Answer Incorrect Answer

    Solution

    All Light are Pole (A) + No Pole is Metal (E) → No Light is a Metal (E) → Probable conclusion → No conclusion. Hence conclusion I does not follow. Some Steel is Light (I) + All Light are Pole (A) → Some Steel are Pole (I) → Probable conclusion → All Pole may be Steel (A). Hence conclusion II follows.
