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_7, x_7 will make tea and x_7 is an artist. For all x_7, if x_7 were a mechanic, then x_7 is not a bartender. For all x_7, if x_7 makes tea, then x_7 is a bartender.
For all x_7, x_7 will make tea can be inferred via the universal simplification rule. For all x_7, x_7 is an artist can be inferred via the universal simplification rule.
