Translate the following inference to logic notation: There is at least one x for which x_1 will not climb a mountain or x_1 will play squash. For all x, x_1 will climb a mountain. Therefore there is at least one x for which x_1 will go running or x_1 will play squash.
exists x: ~P(x) or Q(x). forall x: P(x). Therefore exists x: R(x) or Q(x).
