Translate the following inference to logic notation: There is at least one x for which x_10 will drive a car. For all x, x_10 is happy. For all x, x_10 will read a book. Therefore there is at least one x for which x_10 is happy and x_10 will drive a car.
exists x: P(x). forall x: Q(x). forall x: R(x). Therefore exists x: Q(x) and P(x).
