Consider the following premises. For all x_10, x_10 will make tea. For all x_10, if x_10 sleeps, then x_10 is reading a book. For all x_10, if x_10 were a scientist, then x_10 is sleeping. For all x_10, if x_10 sleeps, then x_10 is not making tea. For all x_10, if x_10 reads a book, then x_10 is drinking water. For all x_10, if x_10 drinks water, then x_10 is a scientist. Can we infer the following from them? For all x_10, x_10 is not a scientist.
 From the fact that for all x_10, if x_10 sleeps, then x_10 is reading a book, and that for all x_10, if x_10 reads a book, then x_10 is drinking water we can infer that for all x_10, if x_10 sleeps, then x_10 is drinking water. From the fact that for all x_10, if x_10 sleeps, then x_10 is drinking water, and that for all x_10, if x_10 drinks water, then x_10 is a scientist we can infer that for all x_10, if x_10 sleeps, then x_10 is a scientist. From the fact that for all x_10, if x_10 sleeps, then x_10 is not making tea, and that for all x_10, x_10 will make tea we can infer that for all x_10, x_10 will not sleep. From the fact that for all x_10, if x_10 sleeps, then x_10 is a scientist, and that for all x_10, if x_10 were a scientist, then x_10 is sleeping we can infer that for all x_10, x_10 will sleep if and only if x_10 is a scientist. Finally, from the fact that for all x_10, x_10 will sleep if and only if x_10 is a scientist, and that for all x_10, x_10 will not sleep we can infer that for all x_10, x_10 is not a scientist. Therefore, the answer is yes.
