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_10, if x_10 were bored, then x_10 is sleeping. For all x_10, x_10 is bored or x_10 will not sleep. Mary is bored.
There is at least one x for which x is bored can be inferred via the existential generalization rule. For all x_10, if x_10 sleeps, then x_10 is bored can be inferred via the universal rewriting rule.
