Answer choice (B) states: "Either a democracy does not function well or else the electorate is not moral or not intelligent."
"Either/or" is Sufficient and Necessary language. Our rule for diagramming this is to pick one variable to negate and make into our Sufficient condition. The other variable is left to be our Necessary condition.
The variables in (B) are: (1) not DFW; (2) not M or not I
We pick the first variable - "not DFW" - to negate and make into our Sufficient condition. This means our Sufficient condition is "DFW." We make "not M or not I" into our Necessary condition. This gives us: DFW -> not M or not I.
So, our diagram shows "DFW" because of our rule for diagramming either/or statements.
Does that make sense? Please let us know if you have any other questions!
