    Statements: No swan is a penguin.

                               Some penguins are kingfisher. Conclusions: I. Some swan are not kingfisher.                        II. Some kingfisher are penguins. In each question below are given two statements followed by two conclusions numbered I and II. You have to take the two given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts. Give Answer:
    A If 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 conclusions I and II follow Correct Answer Incorrect Answer

    Solution

    No swan is a penguin (E) + Some penguins are kingfisher (I) ⇒ Some kingfisher are not swan (O*) . Hence, conclusion I will not follow. Some penguins are kingfisher (I) ⇒ conversion ⇒ Some kingfisher are penguins(I). Hence, conclusion II will follow.
