Translate the following inference to logic notation: For all x, if x_8 drinks water, then x_8 is a poet. For all x, x_8 is a sailor if and only if x_8 will go running. For all x, x_8 is a sailor if and only if x_8 is a poet. For all x, x_8 will not go running. Therefore for all x, x_8 will not drink water.
forall x: P(x) -> Q(x). forall x: R(x) <-> S(x). forall x: R(x) <-> Q(x). forall x: ~S(x). Therefore forall x: ~P(x).
