Translate the following inference to logic notation: For all x, if x_8 were fast, then x_8 is an electrician. For all x, x_8 will not sleep or x_8 is an astronaut. For all x, if x_8 were curious, then x_8 is an electrician. For all x, x_8 will not make tea or x_8 is curious. For all x, x_8 will sleep or x_8 will make tea. For all x, if x_8 were an astronaut, then x_8 is fast. Therefore for all x, x_8 is an electrician.
forall x: P(x) -> Q(x). forall x: ~R(x) or S(x). forall x: T(x) -> Q(x). forall x: ~U(x) or T(x). forall x: R(x) or U(x). forall x: S(x) -> P(x). Therefore forall x: Q(x).
