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: Karen is not taking a plane. For all x_5, x_5 will take a plane or x_5 is not a server. For all x_5, if x_5 takes a plane, then x_5 is a server.
For all x_5, if x_5 were a server, then x_5 is taking a plane can be inferred via the universal rewriting rule.
