Complete the steps of the argument below. For each step, choose a rule of inference or logical equivalence that justifies the step and indicate which statements the rule is applied to. To reference previous statements, write their numbers separated by commas (e.g.: 1 or 1,2 or 1,2,3). 1. 3x¬U(x) 2. Vx (P(x) → U(x)) 3. ¬U (b) for some b, using Existential Instantiation with 1 4.
