Consider the following premises. If it doesn't snow, then Joseph is playing a game. If it snows, then Charles is reading a book. For all x_14, x_14 will not read a book. Can we infer the following from them? Joseph is playing a game.
 From the fact that for all x_14, x_14 will not read a book we can infer that Charles is not reading a book. From the fact that if it snows, then Charles is reading a book, and that Charles is not reading a book we can infer that it is not snowing. Finally, from the fact that if it doesn't snow, then Joseph is playing a game, and that it is not snowing we can infer that Joseph is playing a game. Therefore, the answer is yes.
