Translate the following inference to logic notation: For all x, if x_10 plays tennis, then x_10 is an artist. For all x, if x_10 were an artist, then x_10 is fast. There is at least one x for which x_10 will play tennis if and only if x_10 will drink water. Therefore there is at least one x for which if x_10 drinks water, then x_10 is fast.
forall x: P(x) -> Q(x). forall x: Q(x) -> R(x). exists x: P(x) <-> S(x). Therefore exists x: S(x) -> R(x).
