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: There is at least one x_7 for which x_7 is bored or x_7 is not a poet. For all x_7, x_7 is a nurse or x_7 is not bored.
For all x_7, if x_7 were bored, then x_7 is a nurse can be inferred via the universal rewriting rule. There is at least one x_7 for which if x_7 were a poet, then x_7 is bored can be inferred via the existential rewriting rule.
