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: Michael is drinking water or Linda is not an office clerk. If Michael were a musician, then Linda is an office clerk. For all x_15, if x_15 drinks water, then x_15 is a musician.
If Linda were an office clerk, then Michael is drinking water can be inferred via the rewriting rule.
