Translate the following inference to logic notation: For all x, if x_6 were a taxi driver, then x_6 is reading a book. For all x, if x_6 plays squash, then x_6 is a taxi driver. For all x, x_6 will play squash. For all x, x_6 will cook. Therefore for all x, x_6 will cook.
forall x: P(x) -> Q(x). forall x: R(x) -> P(x). forall x: R(x). forall x: S(x). Therefore forall x: S(x).
