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: If Richard plays squash, then Jessica is not an artist. For all x_14, if x_14 goes running, then x_14 is an artist. For all x_14, if x_14 were a nurse, then x_14 is running. For all x_14, x_14 is a nurse.
For all x_14, x_14 will go running can be inferred via the universal modus ponens rule. For all x_14, if x_14 were a nurse, then x_14 is an artist can be inferred via the universal transitivity rule.
