Translate the following inference to logic notation: For all x, if x_9 were an office clerk, then x_9 is listening to a song. For all x, if x_9 reads a book, then x_9 is cooking. For all x, if x_9 plays tennis, then x_9 is reading a book. For all x, x_9 is an office clerk or x_9 will not cook. Therefore for all x, if x_9 plays tennis, then x_9 is listening to a song.
forall x: P(x) -> Q(x). forall x: R(x) -> S(x). forall x: T(x) -> R(x). forall x: P(x) or ~S(x). Therefore forall x: T(x) -> Q(x).
