    Another way of thinking about this is that "except" and "without" are basically synonyms for "or." That is, when you say that A will happen unless B, your are basically saying A will happen, or else B will happen.

    A except B

    /B—>A

    You could also say, A will happen unless B occurs.that makes it group 3 negate sufficient.
