Consider the following premises. There is at least one x_9 for which if x_9 were an artist, then x_9 is reading a book. For all x_9, if x_9 reads a book, then x_9 is making tea. For all x_9, x_9 is bored or x_9 is an artist. For all x_9, x_9 will make tea if and only if x_9 is bored. Can we infer the following from them? For all x_9, x_9 will not make tea.
 From the fact that for all x_9, x_9 will make tea if and only if x_9 is bored we can infer that for all x_9, if x_9 were bored, then x_9 is making tea. From the fact that there is at least one x_9 for which if x_9 were an artist, then x_9 is reading a book, and that for all x_9, if x_9 reads a book, then x_9 is making tea we can infer that there is at least one x_9 for which if x_9 were an artist, then x_9 is making tea. Finally, from the fact that for all x_9, if x_9 were bored, then x_9 is making tea, that there is at least one x_9 for which if x_9 were an artist, then x_9 is making tea, and that for all x_9, x_9 is bored or x_9 is an artist we can infer that there is at least one x_9 for which x_9 will make tea, which contradicts that For all x_9, x_9 will not make tea. Therefore, the answer is no.
