Translate the following inference to logic notation: For all x, if x_8 plays squash, then x_8 is not a musician. For all x, if x_8 reads a book, then x_8 is playing squash. For all x, x_8 is a musician. For all x, if x_8 plays squash, then x_8 is reading a book. For all x, if x_8 plays squash, then x_8 is reading a book. Therefore for all x, x_8 will not read a book.
forall x: P(x) -> ~Q(x). forall x: R(x) -> P(x). forall x: Q(x). forall x: P(x) -> R(x). forall x: P(x) -> R(x). Therefore forall x: ~R(x).
