Consider the following premises. For all x_18, x_18 is not an artist. For all x_18, x_18 will work or x_18 is a carpenter. For all x_18, if x_18 plays squash, then x_18 is an artist. There is at least one x_18 for which if x_18 works, then x_18 is playing squash. Can we infer the following from them? There is at least one x_18 for which x_18 is a carpenter or x_18 is a politician.
 From the fact that there is at least one x_18 for which if x_18 works, then x_18 is playing squash, and that for all x_18, if x_18 plays squash, then x_18 is an artist we can infer that there is at least one x_18 for which if x_18 works, then x_18 is an artist. From the fact that there is at least one x_18 for which if x_18 works, then x_18 is an artist, and that for all x_18, x_18 is not an artist we can infer that there is at least one x_18 for which x_18 will not work. From the fact that for all x_18, x_18 will work or x_18 is a carpenter, and that there is at least one x_18 for which x_18 will not work we can infer that there is at least one x_18 for which x_18 is a carpenter. Finally, from the fact that there is at least one x_18 for which x_18 is a carpenter we can infer that there is at least one x_18 for which x_18 is a carpenter or x_18 is a politician. Therefore, the answer is yes.
