When I first attempted to do this problem in the LG Bible awhile ago, I failed miserably and was completely stumped.
After much practice from the course, I retried it. I am happy that I only missed 3 this time, but I missed one of the key inferences! J and s can be together! Consequently, I missed 3 problems that required this info. Question: How to avoid this in the future? What is the best way to diagram problems such as this? Should I spend more time trying to write ALL of the inferences (as the explanation is in the LG Bible and the HW book) or should I just "diagram" the rules with the appropriate arrows and read my inferences that way? I hope this question makes sense. Thank you for your help.
