Translate the following inference to logic notation: For all x, x_8 will play tennis or x_8 will play squash. For all x, if x_8 plays squash, then x_8 is climbing a mountain. For all x, x_8 will climb a mountain or x_8 will not go running. For all x, x_8 is a mechanic. For all x, x_8 will not play tennis or x_8 will go running. Therefore for all x, x_8 will climb a mountain and x_8 is a mechanic.
forall x: P(x) or Q(x). forall x: Q(x) -> R(x). forall x: R(x) or ~S(x). forall x: T(x). forall x: ~P(x) or S(x). Therefore forall x: R(x) and T(x).
