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 a janitor. For all x_16, x_16 will play squash. For all x_16, x_16 is a soldier.
There is at least one x for which x is a janitor can be inferred via the existential generalization rule. For all x_16, x_16 will play squash and x_16 is a soldier can be inferred via the universal conjunction rule. For all x_16, x_16 is a soldier and x_16 will play squash can be inferred via the universal conjunction rule.
