Consider the following premises. For all y, y will play a game. Richard is an astronaut. Can we infer the following from them? If we can, name the inference rule being used: James is playing a game and Richard is an astronaut.
 From the fact that for all y, y will play a game we can infer that James is playing a game via universal instantiation. Finally, from the fact that James is playing a game, and that Richard is an astronaut we can infer that James is playing a game and Richard is an astronaut via conjunction. Therefore, the answer is yes.
