Consider the following premises. For all x_16, x_16 is not bored. For all x_16, if x_16 were an electrician, then x_16 is reading a book. For all x_16, if x_16 were a scientist, then x_16 is an electrician. For all x_16, if x_16 takes a plane, then x_16 is bored. For all x_16, x_16 will take a plane if and only if x_16 will read a book. Can we infer the following from them? There is at least one x_16 for which x_16 is a scientist.
 From the fact that for all x_16, x_16 will take a plane if and only if x_16 will read a book we can infer that for all x_16, if x_16 reads a book, then x_16 is taking a plane. From the fact that for all x_16, if x_16 takes a plane, then x_16 is bored, and that for all x_16, x_16 is not bored we can infer that for all x_16, x_16 will not take a plane. From the fact that for all x_16, if x_16 were an electrician, then x_16 is reading a book, and that for all x_16, if x_16 reads a book, then x_16 is taking a plane we can infer that for all x_16, if x_16 were an electrician, then x_16 is taking a plane. From the fact that for all x_16, if x_16 were an electrician, then x_16 is taking a plane, and that for all x_16, x_16 will not take a plane we can infer that for all x_16, x_16 is not an electrician. Finally, from the fact that for all x_16, if x_16 were a scientist, then x_16 is an electrician, and that for all x_16, x_16 is not an electrician we can infer that for all x_16, x_16 is not a scientist, which contradicts that There is at least one x_16 for which x_16 is a scientist. Therefore, the answer is no.
