Answer: Yes. For example, if KB TRUE, then it cannot entail a sentence S unless S is a tautology. So, if we pick S P, where P is a propositional symbol, then TRUE 6j= P and TRUE 6j= :P. (f)(KB 6j= S) and (:KB 6j= S) Answer: Yes. For example, if KB P and S Q, where P and Q are propositional symbols, then P 6j= Q and :P 6j= Q. If so, provide an ...
