Translate the following inference to logic notation: For all x, x_10 is curious. For all x, x_10 will drink water. There is at least one x for which if x_10 drinks water, then x_10 is reading a book. For all x, if x_10 were happy, then x_10 is reading a book. Therefore there is at least one x for which x_10 will read a book and x_10 is curious.
forall x: P(x). forall x: Q(x). exists x: Q(x) -> R(x). forall x: S(x) -> R(x). Therefore exists x: R(x) and P(x).
