Translate the following inference to logic notation: For all x, x_11 is a poet if and only if x_11 will read a book. There is at least one x for which x_11 is a musician. For all x, if x_11 were a poet, then x_11 is not playing squash. For all x, if x_11 were a musician, then x_11 is playing squash. Therefore there is at least one x for which x_11 will not read a book.
forall x: P(x) <-> Q(x). exists x: R(x). forall x: P(x) -> ~S(x). forall x: R(x) -> S(x). Therefore exists x: ~Q(x).
