Which of the following statements are true regarding logic? If P is True and Q is False, then ((P∨Q) ∧¬Q) ⇒P is true. Given KB, we aim to infer α. We can use proof by contradition to show that KB⇒α is unsatifiable Both Forward chaining and Backward chaining work for any horn clauses. Horn clauses can have two positive literals.
