Translate the following inference to logic notation: For all x, if x_10 drinks water, then x_10 is playing squash. For all x, if x_10 drinks water, then x_10 is a bartender. For all x, if x_10 plays squash, then x_10 is drinking water. For all x, if x_10 works, then x_10 is sleeping. For all x, if x_10 were a bartender, then x_10 is working. Therefore for all x, if x_10 plays squash, then x_10 is sleeping.
forall x: P(x) -> Q(x). forall x: P(x) -> R(x). forall x: Q(x) -> P(x). forall x: S(x) -> T(x). forall x: R(x) -> S(x). Therefore forall x: Q(x) -> T(x).
