Consider the following premises. For all x_12, if x_12 were a lawyer, then x_12 is an electrician. For all x_12, if x_12 works, then x_12 is not an electrician. For all x_12, x_12 is a lawyer or x_12 is not a politician. For all x_12, if x_12 were a soldier, then x_12 is an electrician. For all x_12, x_12 is a soldier. Can we infer the following from them? There is at least one x_12 for which x_12 will work.
 From the fact that for all x_12, x_12 is a lawyer or x_12 is not a politician we can infer that for all x_12, if x_12 were a politician, then x_12 is a lawyer. From the fact that for all x_12, x_12 is a soldier we can infer that for all x_12, x_12 is a soldier or x_12 is a politician. From the fact that for all x_12, if x_12 were a politician, then x_12 is a lawyer, and that for all x_12, if x_12 were a lawyer, then x_12 is an electrician we can infer that for all x_12, if x_12 were a politician, then x_12 is an electrician. From the fact that for all x_12, if x_12 were a soldier, then x_12 is an electrician, that for all x_12, if x_12 were a politician, then x_12 is an electrician, and that for all x_12, x_12 is a soldier or x_12 is a politician we can infer that for all x_12, x_12 is an electrician. Finally, from the fact that for all x_12, if x_12 works, then x_12 is not an electrician, and that for all x_12, x_12 is an electrician we can infer that for all x_12, x_12 will not work, which contradicts that There is at least one x_12 for which x_12 will work. Therefore, the answer is no.
