Translate the following inference to logic notation: There is at least one x for which if x_5 reads a book, then x_5 is excited. For all x, x_5 will take a plane. For all x, x_5 will not take a plane. Therefore there is at least one x for which x_5 is excited.
exists x: P(x) -> Q(x). forall x: R(x). forall x: ~R(x). Therefore exists x: Q(x).
