Translate the following inference to logic notation: For all x, x_16 is not fast or x_16 is curious. For all x, if x_16 plays tennis, then x_16 is writing a letter. For all x, x_16 is fast or x_16 is a musician. For all x, x_16 is a musician if and only if x_16 will take a plane. There is at least one x for which if x_16 writes a letter, then x_16 is taking a plane. For all x, if x_16 were curious, then x_16 is playing tennis. Therefore there is at least one x for which x_16 will take a plane.
forall x: ~P(x) or Q(x). forall x: R(x) -> S(x). forall x: P(x) or T(x). forall x: T(x) <-> U(x). exists x: S(x) -> U(x). forall x: Q(x) -> R(x). Therefore exists x: U(x).
