Translate the following inference to logic notation: There is at least one x for which if x_10 were a sailor, then x_10 is a janitor. For all x, x_10 is a sailor or x_10 will climb a mountain. For all x, if x_10 were a janitor, then x_10 is a cashier. For all x, if x_10 climbs a mountain, then x_10 is a cashier. For all x, x_10 is a server. Therefore there is at least one x for which x_10 is a server and x_10 is a cashier.
exists x: P(x) -> Q(x). forall x: P(x) or R(x). forall x: Q(x) -> S(x). forall x: R(x) -> S(x). forall x: T(x). Therefore exists x: T(x) and S(x).
