    Direction: In each of the following questions two statements are given followed by two three or four conclusions numbered I, II, III, and IV. 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 books are papers. All papers are grasses. Conclusions:            
    I. Some grasses are books
    II. Some grasses are papers

    A) Only conclusion I follows                        

    B) Only conclusion II follows

    C) Either conclusion I or II follows                

    D) Neither conclusion I nor II follows

    E) Both conclusions I and II follow

    Correct Answer: E

    Solution :

    Explanation Option [e] is correct. Since both the premises are universal and affirmative, the conclusion must be universal affirmative and should not contain the middle term. So, it follows that ?All books are grasses?. I is the converse of this conclusion and so it holds, II is the converse of the second premise and so it also holds.
