Consider the following premises. Jessica is happy or it is cloudy. Jessica is not driving a car. For all x_14, x_14 will drive a car if and only if x_14 is happy. Can we infer the following from them? If we can, name the inference rule being used: Linda is playing a game or it is cloudy.
 From the fact that for all x_14, x_14 will drive a car if and only if x_14 is happy we can infer that Jessica is driving a car if and only if Jessica is happy via universal instantiation. From the fact that Jessica is driving a car if and only if Jessica is happy, and that Jessica is not driving a car we can infer that Jessica is not happy via biconditional elimination. From the fact that Jessica is not happy we can infer that Jessica is not happy or Linda is playing a game via addition. Finally, from the fact that Jessica is not happy or Linda is playing a game, and that Jessica is happy or it is cloudy we can infer that Linda is playing a game or it is cloudy via resolution. Therefore, the answer is yes.
