Translate the following inference to logic notation: For all x, x_13 will play squash if and only if x_13 is an astronaut. For all x, x_13 is not an artist or x_13 is poor. For all x, if x_13 were bored, then x_13 is an astronaut. For all x, if x_13 were fast, then x_13 is playing squash. For all x, if x_13 were poor, then x_13 is bored. For all x, x_13 is an artist or x_13 is fast. Therefore for all x, x_13 is an astronaut.
forall x: P(x) <-> Q(x). forall x: ~R(x) or S(x). forall x: T(x) -> Q(x). forall x: U(x) -> P(x). forall x: S(x) -> T(x). forall x: R(x) or U(x). Therefore forall x: Q(x).
