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: There is at least one x_24 for which x_24 will not listen to a song. For all x_24, x_24 is a lawyer if and only if x_24 is fast. For all x_24, if x_24 drinks water, then x_24 is a lawyer. For all x_24, x_24 will make tea or x_24 will drink water. For all x_24, x_24 will make tea if and only if x_24 will listen to a song.
For all x_24, if x_24 were a lawyer, then x_24 is fast can be inferred via the universal biconditional elimination rule. For all x_24, if x_24 makes tea, then x_24 is listening to a song can be inferred via the universal biconditional elimination rule. For all x_24, if x_24 were fast, then x_24 is a lawyer can be inferred via the universal biconditional elimination rule. For all x_24, if x_24 listens to a song, then x_24 is making tea can be inferred via the universal biconditional elimination rule. There is at least one x_24 for which x_24 will not make tea can be inferred via the existential biconditional elimination rule.
