Diagramming the Conditional in the Stimulus

I got this answer choice correct because it was the closest to what I came up with, but I diagrammed out the conditional as not Water AND not Sun AND not Social but you guys used OR. That makes the answer choice flow and make absolute sense, but how did you know to use or when diagramming instead of and, especially since the stimulus uses 'and'?

not Soil*

Hi Skraps17,

I think the original statement is an And. We have three equal necessary conditions, good soil, good water, and good sun.

The contrapositive would be an or (if missing sun or water or soil then not productive), but for the initial statement I would absolutely go with and.

but I don't understand because if introduces sufficient condition not necessary, so if there isn't water , soil and sun then not productive. therefore not productive is the necessary in this case. please someone explain
