What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: Michael is a politician or it is not late. For all x_14, x_14 is a politician if and only if x_14 is fast. Michael is fast or it is late.
If it is late, then Michael is a politician can be inferred via the rewriting rule. For all x_14, if x_14 were a politician, then x_14 is fast can be inferred via the universal biconditional elimination rule. For all x_14, if x_14 were fast, then x_14 is a politician can be inferred via the universal biconditional elimination rule.
