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: Patricia is not cooking or it is snowing. For all x_8, x_8 is poor or x_8 will cook. Patricia is not a sailor. For all x_8, x_8 is not poor or x_8 is a sailor.
For all x_8, x_8 will cook or x_8 is a sailor can be inferred via the universal resolution rule.
