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_10 for which x_10 will drink water if and only if x_10 is bored. For all x_10, x_10 is bored or x_10 will not go running. For all x_10, x_10 will not drink water.
For all x_10, if x_10 goes running, then x_10 is bored can be inferred via the universal rewriting rule. There is at least one x_10 for which if x_10 drinks water, then x_10 is bored can be inferred via the existential biconditional elimination rule. There is at least one x_10 for which if x_10 were bored, then x_10 is drinking water can be inferred via the existential biconditional elimination rule. There is at least one x_10 for which x_10 is not bored can be inferred via the existential biconditional elimination rule.
