What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? 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 drink water. For all x_10, x_10 will drive a car. For all x_10, if x_10 drives a car, then x_10 is making tea.
Since the premises are contradictory, we can infer anything from them.
