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_5, x_5 is an electrician. For all x_5, if x_5 goes running, then x_5 is a scientist. For all x_5, if x_5 were an electrician, then x_5 is running. There is at least one x_5 for which if x_5 were a scientist, then x_5 is bored.
For all x_5, x_5 will go running can be inferred via the universal modus ponens rule. For all x_5, if x_5 were an electrician, then x_5 is a scientist can be inferred via the universal transitivity rule. There is at least one x_5 for which if x_5 goes running, then x_5 is bored can be inferred via the existential transitivity rule.
