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_14, x_14 is a musician and x_14 will sleep. There is at least one x_14 for which x_14 will drink water and x_14 will play squash.
For all x_14, x_14 is a musician can be inferred via the universal simplification rule. For all x_14, x_14 will sleep can be inferred via the universal simplification rule. There is at least one x_14 for which x_14 will drink water can be inferred via the existential simplification rule. There is at least one x_14 for which x_14 will play squash can be inferred via the existential simplification rule.
