Translate the following inference to logic notation: For all x, x_6 will drink water if and only if x_6 will climb a mountain. For all x, x_6 is not a scientist. For all x, if x_6 climbs a mountain, then x_6 is not a soldier. For all x, x_6 is a scientist or x_6 is a soldier. Therefore for all x, x_6 will not drink water.
forall x: P(x) <-> Q(x). forall x: ~R(x). forall x: Q(x) -> ~S(x). forall x: R(x) or S(x). Therefore forall x: ~P(x).
