Consider the following premises. For all x_2, if x_2 were a lawyer, then x_2 is a mechanic. For all x_2, x_2 is not a lawyer. For all x_2, if x_2 drinks water, then x_2 is a lawyer. For all x_2, if x_2 were a mechanic, then x_2 is drinking water. Can we infer the following from them? For all x_2, x_2 will not drink water.
 From the fact that for all x_2, if x_2 were a lawyer, then x_2 is a mechanic, and that for all x_2, if x_2 were a mechanic, then x_2 is drinking water we can infer that for all x_2, if x_2 were a lawyer, then x_2 is drinking water. From the fact that for all x_2, if x_2 drinks water, then x_2 is a lawyer, and that for all x_2, if x_2 were a lawyer, then x_2 is drinking water we can infer that for all x_2, x_2 will drink water if and only if x_2 is a lawyer. Finally, from the fact that for all x_2, x_2 will drink water if and only if x_2 is a lawyer, and that for all x_2, x_2 is not a lawyer we can infer that for all x_2, x_2 will not drink water. Therefore, the answer is yes.
