Translate the following inference to logic notation: For all x, if x_1 plays squash, then x_1 is making tea. For all x, if x_1 were a mechanic, then x_1 is playing squash. For all x, x_1 is a mechanic. Therefore for all x, x_1 will make tea.
forall x: P(x) -> Q(x). forall x: R(x) -> P(x). forall x: R(x). Therefore forall x: Q(x).
