Consider the following premises. For all x_16, if x_16 were an electrician, then x_16 is a carpenter. There is at least one x_16 for which if x_16 were a janitor, then x_16 is working. For all x_16, x_16 is a scientist if and only if x_16 will work. For all x_16, x_16 is a soldier or x_16 is a scientist. For all x_16, x_16 is not a soldier or x_16 is an electrician. For all x_16, if x_16 were a carpenter, then x_16 is a janitor. Can we infer the following from them? There is at least one x_16 for which x_16 will work.
 From the fact that for all x_16, x_16 is a soldier or x_16 is a scientist, and that for all x_16, x_16 is not a soldier or x_16 is an electrician we can infer that for all x_16, x_16 is a scientist or x_16 is an electrician. From the fact that for all x_16, x_16 is a scientist if and only if x_16 will work we can infer that for all x_16, if x_16 were a scientist, then x_16 is working. From the fact that for all x_16, if x_16 were a carpenter, then x_16 is a janitor, and that there is at least one x_16 for which if x_16 were a janitor, then x_16 is working we can infer that there is at least one x_16 for which if x_16 were a carpenter, then x_16 is working. From the fact that for all x_16, if x_16 were an electrician, then x_16 is a carpenter, and that there is at least one x_16 for which if x_16 were a carpenter, then x_16 is working we can infer that there is at least one x_16 for which if x_16 were an electrician, then x_16 is working. Finally, from the fact that for all x_16, if x_16 were a scientist, then x_16 is working, that there is at least one x_16 for which if x_16 were an electrician, then x_16 is working, and that for all x_16, x_16 is a scientist or x_16 is an electrician we can infer that there is at least one x_16 for which x_16 will work. Therefore, the answer is yes.
