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 drinks water, then x_10 is making tea. For all x_10, if x_10 makes tea, then x_10 is drinking water. For all x_10, if x_10 drinks water, then x_10 is making tea. For all x_10, x_10 will not drink water. For all x_10, x_10 will make tea if and only if x_10 will go running.
For all x_10, x_10 will not make tea can be inferred via the universal modus tollens rule. For all x_10, x_10 will drink water if and only if x_10 will make tea can be inferred via the universal biconditional introduction rule. For all x_10, x_10 will make tea if and only if x_10 will drink water can be inferred via the universal biconditional introduction rule. For all x_10, x_10 will make tea if and only if x_10 will drink water can be inferred via the universal biconditional introduction rule. For all x_10, x_10 will drink water if and only if x_10 will make tea can be inferred via the universal biconditional introduction rule. For all x_10, if x_10 makes tea, then x_10 is running can be inferred via the universal biconditional elimination rule. For all x_10, if x_10 goes running, then x_10 is making tea can be inferred via the universal biconditional elimination rule.
