Consider the following premises. For all x_3, x_3 will read a book and x_3 will drive a car. Can we infer the following from them? If we can, name the inference rule being used: For all x_3, x_3 will read a book or x_3 will work.
 From the fact that for all x_3, x_3 will read a book and x_3 will drive a car we can infer that for all x_3, x_3 will read a book via universal simplification. Finally, from the fact that for all x_3, x_3 will read a book we can infer that for all x_3, x_3 will read a book or x_3 will work via universal addition. Therefore, the answer is yes.
