Translate the following inference to logic notation: For all x, if x_10 reads a book, then x_10 is a musician. There is at least one x for which if x_10 takes a plane, then x_10 is a musician. For all x, x_10 will read a book if and only if x_10 will drive a car. For all x, x_10 will take a plane. Therefore there is at least one x for which x_10 is a musician.
forall x: P(x) -> Q(x). exists x: R(x) -> Q(x). forall x: P(x) <-> S(x). forall x: R(x). Therefore exists x: Q(x).
