Consider the following premises. There is at least one x_18 for which if x_18 were a doctor, then x_18 is reading a book. For all x_18, x_18 will sleep. For all x_18, x_18 is an artist. For all x_18, x_18 is bored. For all x_18, if x_18 were bored, then x_18 is not an artist. Can we infer the following from them? There is at least one x_18 for which x_18 will sleep and x_18 will read a book.
 From the fact that for all x_18, x_18 is bored we can infer that for all x_18, x_18 is bored or x_18 is a doctor. From the fact that for all x_18, if x_18 were bored, then x_18 is not an artist, and that for all x_18, x_18 is an artist we can infer that for all x_18, x_18 is not bored. From the fact that for all x_18, x_18 is bored or x_18 is a doctor, and that for all x_18, x_18 is not bored we can infer that for all x_18, x_18 is a doctor. From the fact that there is at least one x_18 for which if x_18 were a doctor, then x_18 is reading a book, and that for all x_18, x_18 is a doctor we can infer that there is at least one x_18 for which x_18 will read a book. Finally, from the fact that for all x_18, x_18 will sleep, and that there is at least one x_18 for which x_18 will read a book we can infer that there is at least one x_18 for which x_18 will sleep and x_18 will read a book. Therefore, the answer is yes. Notice, however, that the premises were contradictory, so we can infer anything from them.
