You have to take the given statements to be true even if they seem to be at variance from the commonly known facts and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.
    Statements: All animals are consumers. All animals are carnivores. Conclusions:            
    I. Either all carnivores are consumers or all consumers are carnivores.
    II. Some consumers are carnivores.
    III. Generally carnivores are consumers.

    A) Only I follows     

    B)               Only I and III follow

    C) Only II follows   

    D) None follows

    E) All follow

    Correct Answer: C

    Solution :

    Explanation Option [c] is correct. Since the middle term ?animals? is distributed twice in the premises, the conclusion cannot be universal. So, it follows that ?Some consumers are carnivores?. Thus, II holds.
