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 raining or Elisabeth is not making tea. For all x_14, x_14 will make tea if and only if x_14 is a poet.
If Elisabeth makes tea, then it is raining can be inferred via the rewriting rule. For all x_14, if x_14 makes tea, then x_14 is a poet can be inferred via the universal biconditional elimination rule. For all x_14, if x_14 were a poet, then x_14 is making tea can be inferred via the universal biconditional elimination rule.
