For the argument completion drill:
P: C--->Not D
C: not D-some-X
I first translated the conclusion to X--->Not D
So we have C---->Not D and to get to the conclusion, I would think we'd need X---->C
So that would be X--->C--->not D so by the transitive property, X---->Not D
Why is the answer C----->X?
Already have an account?
