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 z_3, z_3 will make tea. For all z_3, z_3 will go running. For all z_3, if z_3 goes running, then z_3 is an artist.
For all z_3, z_3 is an artist can be inferred via the universal modus ponens rule. For all z_3, z_3 will make tea and z_3 will go running can be inferred via the universal conjunction rule. For all z_3, z_3 will go running and z_3 will make tea can be inferred via the universal conjunction rule.
