    Fact: A gazelle is fast
    Q: Is a gazelle slow?
    
    A: No
    A: No, it is fast
    A: No, it's fast
    A: No, a gazelle is fast
    A: No, fast
    A: No, it's fast, not slow

    Not an answer: Yes
    
    Example solution
    ----------------
    
    Fact: Fast is not slow
    Rule: Y is not Z => Z is not Y
    Rule: a X is Y & Y is not Z => a X is not Z
    Rule: is X Y? & X is not Y => no
