Consider the following premises. It is windy. For all x_9, x_9 will read a book. Can we infer the following from them? If we can, name the inference rule being used: John is reading a book and it is windy.
 From the fact that for all x_9, x_9 will read a book we can infer that John is reading a book via universal instantiation. Finally, from the fact that John is reading a book, and that it is windy we can infer that John is reading a book and it is windy via conjunction. Therefore, the answer is yes.
