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_1, x_1 will go running. For all x_1, if x_1 goes running, then x_1 is a carpenter.
For all x_1, x_1 is a carpenter can be inferred via the universal modus ponens rule.
