Translate the following inference to logic notation: For all x, x_14 will drive a car if and only if x_14 is a musician. For all x, x_14 will drink water or x_14 will write a letter. For all x, x_14 is curious if and only if x_14 will drive a car. For all x, x_14 will not drink water or x_14 is curious. For all x, if x_14 writes a letter, then x_14 is a musician. Therefore for all x, x_14 is a musician.
forall x: P(x) <-> Q(x). forall x: R(x) or S(x). forall x: T(x) <-> P(x). forall x: ~R(x) or T(x). forall x: S(x) -> Q(x). Therefore forall x: Q(x).
