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_8 for which x_8 is a carpenter or x_8 is not a server. For all x_8, if x_8 were a politician, then x_8 is a server. For all x_8, if x_8 goes running, then x_8 is a carpenter. For all x_8, x_8 will go running or x_8 is a politician.
There is at least one x_8 for which if x_8 were a server, then x_8 is a carpenter can be inferred via the existential rewriting rule.
