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: It is windy. For all x_17, x_17 will drink water if and only if x_17 is an artist. Barbara is an artist or it is not windy.
If it is windy, then Barbara is an artist can be inferred via the rewriting rule. For all x_17, if x_17 drinks water, then x_17 is an artist can be inferred via the universal biconditional elimination rule. For all x_17, if x_17 were an artist, then x_17 is drinking water can be inferred via the universal biconditional elimination rule.
