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_1, x_1 will cook. For all x_1, if x_1 cooks, then x_1 is drinking water. For all x_1, x_1 is an electrician or x_1 will not drink water.
For all x_1, x_1 will drink water can be inferred via the universal modus ponens rule. For all x_1, if x_1 drinks water, then x_1 is an electrician can be inferred via the universal rewriting rule.
