How do we determine which is the sufficient and necessary condition and which condition should be negated?

Hi A!

I find that for this construction, it helps to convert it into and if/then statement. "No electrician is an architect." I ask myself, what does that really mean? It means: if you're an electrician, then you are not an architect. Once I have it in an if/then statement, it's easy to identify the sufficient (electrician) and necessary (not an architect) conditions.

Sometimes, when you don't have your indicator words, you need to just concentrate on the relationship. If you can convert that relationship into an if/then statement while preserving the meaning of the original statement, it makes diagramming much easier.

Hope this helps!

Best,
Kelsey
