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, x_10 will drink water if and only if x_10 is an artist. For all x_10, x_10 is an artist. 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 an artist can be inferred via the universal biconditional elimination rule. For all x_10, if x_10 were an artist, then x_10 is drinking water can be inferred via the universal biconditional elimination rule.
