Translate the following inference to logic notation: For all x, x_9 is an artist or x_9 is poor. For all x, x_9 will read a book if and only if x_9 is an artist. For all x, x_9 will not go running. There is at least one x for which if x_9 reads a book, then x_9 is running. Therefore there is at least one x for which x_9 is poor.
forall x: P(x) or Q(x). forall x: R(x) <-> P(x). forall x: ~S(x). exists x: R(x) -> S(x). Therefore exists x: Q(x).
