Translate the following inference to logic notation: For all x, x_5 will drink water. For all x, x_5 is curious if and only if x_5 will cook. For all x, if x_5 drinks water, then x_5 is curious. Therefore for all x, x_5 will cook.
forall x: P(x). forall x: Q(x) <-> R(x). forall x: P(x) -> Q(x). Therefore forall x: R(x).
