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, x will go running. For all x, x is not a musician or x is a scientist. For all x, x will go running if and only if x is a musician.
For all x, if x goes running, then x is a musician can be inferred via the universal biconditional elimination rule. For all x, if x were a musician, then x is running can be inferred via the universal biconditional elimination rule.
