Translate the following inference to logic notation: For all x, x_6 is sad or x_6 is a musician. For all x, if x_6 were excited, then x_6 is not curious. For all x, x_6 is not sad. For all x, if x_6 were a musician, then x_6 is curious. Therefore for all x, x_6 is not excited.
forall x: P(x) or Q(x). forall x: R(x) -> ~S(x). forall x: ~P(x). forall x: Q(x) -> S(x). Therefore forall x: ~R(x).
