Translate the following inference to logic notation: For all x, x_9 will sleep or x_9 will not drink water. For all x, if x_9 sleeps, then x_9 is excited. For all x, if x_9 were excited, then x_9 is sleeping. Therefore for all x, if x_9 drinks water, then x_9 is excited.
forall x: P(x) or ~Q(x). forall x: P(x) -> R(x). forall x: R(x) -> P(x). Therefore forall x: Q(x) -> R(x).
