Suppose that some knowledge base contains various propositional-logic sentences that utilize symbols A, B, C, D (connected with various connectives). There are only two cases when the knowledge base is false: - First case: when A is true, B is false, C is false, D is true. - Second case: when A is false, B is true, C is true, D is false. In all other cases, the knowledge base is true. Write a conjunctive normal form (CNF) for the...
