Dave - just verifying that the conclusion here is that the plays aren't successful dramas, right? i diagrammed a bit differently, connecting the two premises:
Therefore, ~ S
Assumption: ~D--> ~ C
Thanks in advance...
bit confused upon diagramming, maybe you can clarify what im doing wrong:
Premise: because Not able to Discern(D)
CONCLUSION not Successful play(suc)
Assumptiom: not D->not Suc
my first inclination was to say the relationship followed as
but why does the relationship should go from the subconclusion to the assumption ?
so it reads:
(cp: not discern-> not care)
In this as in every Sufficient Assumption question, we are asked to prove the conclusion is true.
Here, we know that audiences cannot discern, and if audiences don't care, then a play isn't successful.
We've concluded that the play isn't successful.
But what does discerning have to do with caring? NOTHING. To prove the claim, then, let's fill in that gap and say that discerning = caring.
Or, if you prefer to see it symbolically:
2. ~C → ~S
Now add this sufficient assumption: ~D → ~ C
And our argument works: ~D → ~C → ~S
