Translate the following inference to logic notation: For all x, if x_16 were a taxi driver, then x_16 is reading a book. For all x, if x_16 reads a book, then x_16 is a taxi driver. There is at least one x for which x_16 will drive a car. For all x, x_16 is a taxi driver or x_16 will not drive a car. Therefore there is at least one x for which x_16 will read a book.
forall x: P(x) -> Q(x). forall x: Q(x) -> P(x). exists x: R(x). forall x: P(x) or ~R(x). Therefore exists x: Q(x).
