Translate the following inference to logic notation: For all x, x_5 will read a book or x_5 is not a police officer. For all x, x_5 is a police officer. For all x, if x_5 were a scientist, then x_5 is reading a book. Therefore for all x, x_5 will read a book.
forall x: P(x) or ~Q(x). forall x: Q(x). forall x: R(x) -> P(x). Therefore forall x: P(x).
