Translate the following inference to logic notation: For all x, z_1 is a scientist. For all x, z_1 will work. For all x, if z_1 works, then z_1 is a taxi driver. For all x, if z_1 were a scientist, then z_1 is poor. Therefore for all x, z_1 is a taxi driver and z_1 is poor.
forall x: P(x). forall x: Q(x). forall x: Q(x) -> R(x). forall x: P(x) -> S(x). Therefore forall x: R(x) and S(x).
