Consider the following premises. For all x_18, x_18 will go running. It is windy. If John were a carpenter, then it is not windy. Can we infer the following from them? If we can, name the inference rule being used: John is not a carpenter and Susan is running.
 From the fact that for all x_18, x_18 will go running we can infer that Susan is running via universal instantiation. From the fact that if John were a carpenter, then it is not windy, and that it is windy we can infer that John is not a carpenter via modus tollens. Finally, from the fact that John is not a carpenter, and that Susan is running we can infer that John is not a carpenter and Susan is running via conjunction. Therefore, the answer is yes.
