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: There is at least one x_5 for which x_5 is not an artist or x_5 is a musician. For all x_5, x_5 will not make tea or x_5 will drink water. For all x_5, x_5 will not drink water or x_5 will play squash. For all x_5, x_5 will make tea or x_5 is an artist.
For all x_5, x_5 is an artist or x_5 will drink water can be inferred via the universal resolution rule.
