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, if z drinks water, then z is a scientist. For all z, z is a scientist or z is not a carpenter. For all z, z is a carpenter.
For all z, if z were a carpenter, then z is a scientist can be inferred via the universal rewriting rule.
