Translate the following inference to logic notation: For all x, if x_7 plays squash, then x_7 is not making tea. For all x, x_7 will play squash or x_7 will cook. For all x, x_7 will make tea and x_7 will climb a mountain. Therefore for all x, x_7 will cook.
forall x: P(x) -> ~Q(x). forall x: P(x) or R(x). forall x: Q(x) and S(x). Therefore forall x: R(x).
