    In the question below there are three statements followed by three conclusions I, II and III. You have to take the three given statements to be true even if they seem to be at variance from commonly known facts and then decide which of the given conclusions logically follows from the three statements disregarding commonly known facts.

    Statements: Some songs are guitars.

    >Only guitars are music. No song is an instrument. Conclusions: I. Some music are songs. II. At least some guitars are instruments. III. All music are guitars.
    A Both conclusion I and conclusion II follow. Correct Answer Incorrect Answer
    B Only conclusion I follows Correct Answer Incorrect Answer
    C Neither conclusion I nor conclusion II follows Correct Answer Incorrect Answer
    D Only conclusion III follows Correct Answer Incorrect Answer
    E All conclusions I, II and III follow Correct Answer Incorrect Answer

    Solution

    Only guitars are music → All music are guitars and music cannot have any positive relation with anyone. Hence conclusion I does not follow but conclusion III follows. Some song are guitars (I) → Conversion → Some guitars are song (I) + No song is instrument (E) → Some guitars are not instrument (O). Hence conclusion II does not follow.
