Consider the following premises. If Charles plays a game, then it is raining. Jessica is not a taxi driver. If it rains, then Jessica is a taxi driver. Richard is making tea if and only if Charles is playing a game. Can we infer the following from them? If we can, name the inference rule being used: Richard is not making tea.
 From the fact that if Charles plays a game, then it is raining, and that if it rains, then Jessica is a taxi driver we can infer that if Charles plays a game, then Jessica is a taxi driver via transitivity. From the fact that if Charles plays a game, then Jessica is a taxi driver, and that Jessica is not a taxi driver we can infer that Charles is not playing a game via modus tollens. Finally, from the fact that Richard is making tea if and only if Charles is playing a game, and that Charles is not playing a game we can infer that Richard is not making tea via biconditional elimination. Therefore, the answer is yes.
