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: For all x_7, x_7 will take a plane or x_7 will work. For all x_7, x_7 will not take a plane or x_7 is a poet. For all x_7, if x_7 works, then x_7 is a lawyer. For all x_7, if x_7 were a poet, then x_7 is a lawyer.
For all x_7, x_7 will work or x_7 is a poet can be inferred via the universal resolution rule.
