    Hi Quartarolo 

    0. Change the name of the Reference[Fixed Answers] column to Reference[Answer]

    1. Place Answers[Key] in the a table visual

    2. Create this measure and place it on the visual

    Missing answer =
    VAR answers_ =
        DISTINCT ( Answers[Answer] )
    VAR refAnswers_ =
        ALL ( Reference[Answer] )
    VAR missing_ =
        EXCEPT ( refAnswers_, answers_ )
    RETURN
        CONCATENATEX ( missing_, [Answer], ", " )
