Translate the following inference to logic notation: There is at least one x for which if x_17 were a scientist, then x_17 is a sailor. For all x, x_17 will play squash if and only if x_17 will take a plane. For all x, x_17 is bored if and only if x_17 is a scientist. For all x, x_17 will take a plane if and only if x_17 is bored. For all x, x_17 is not a sailor. Therefore there is at least one x for which x_17 will not play squash.
exists x: P(x) -> Q(x). forall x: R(x) <-> S(x). forall x: T(x) <-> P(x). forall x: S(x) <-> T(x). forall x: ~Q(x). Therefore exists x: ~R(x).
