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_8, x_8 is bored or x_8 will not make tea. There is at least one x_8 for which x_8 is bored if and only if x_8 will make tea.
For all x_8, if x_8 makes tea, then x_8 is bored can be inferred via the universal rewriting rule. There is at least one x_8 for which if x_8 were bored, then x_8 is making tea can be inferred via the existential biconditional elimination rule. There is at least one x_8 for which if x_8 makes tea, then x_8 is bored can be inferred via the existential biconditional elimination rule.
