On number 8, I failed to see that J could be out without K being out, is there a symbology that would help me keep that in mind?

Hi Dave, I think in the games catalog (by template type) you have this listed as standard ordering, and you may want to update that! Thank you!

Re ans. choice D: at first, I didn't get how you tried to make J->K false, but eventually I got it - you couldn't get to that step of trying to make it false due to having followed the first rule, which by default made J->K true. As simple as that was, I couldn't get past that. So while I was stuck, I tried the following on ans. choices C and D:
c) ~O->K->~N
N->~K->O
d) J->~N->K (resulting in J->K)
~K->N->~J (contrapositive ~K->~J)
