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_4, x_4 will go running. For all x_4, x_4 is a scientist. For all x_4, if x_4 goes running, then x_4 is poor.
For all x_4, x_4 is poor can be inferred via the universal modus ponens rule. For all x_4, x_4 will go running and x_4 is a scientist can be inferred via the universal conjunction rule. For all x_4, x_4 is a scientist and x_4 will go running can be inferred via the universal conjunction rule.
