Translate the following inference to logic notation: For all x, if x_13 were a musician, then x_13 is a server. For all x, if x_13 were a soldier, then x_13 is a musician. For all x, x_13 is not bored or x_13 is a soldier. For all x, if x_13 were excited, then x_13 is a writer. For all x, x_13 is a writer if and only if x_13 is a server. For all x, x_13 is bored or x_13 is excited. Therefore for all x, x_13 is a server.
forall x: P(x) -> Q(x). forall x: R(x) -> P(x). forall x: ~S(x) or R(x). forall x: T(x) -> U(x). forall x: U(x) <-> Q(x). forall x: S(x) or T(x). Therefore forall x: Q(x).
