Translate the following inference to logic notation: For all x, x_12 is a scientist. For all x, if x_12 were a police officer, then x_12 is working. For all x, x_12 will read a book or x_12 is a police officer. For all x, x_12 will read a book if and only if x_12 will drink water. For all x, x_12 will not drink water. Therefore for all x, x_12 will work and x_12 is a scientist.
forall x: P(x). forall x: Q(x) -> R(x). forall x: S(x) or Q(x). forall x: S(x) <-> T(x). forall x: ~T(x). Therefore forall x: R(x) and P(x).
