Consider the following premises. If Robert cooks, then Patricia is making tea. If Patricia makes tea, then Richard is driving a car. If it is sunny, then Robert is cooking. If Richard drives a car, then it is sunny. Can we infer the following from them? If we can, name the inference rule being used: The fact that it is sunny does not imply that Richard is driving a car.
 From the fact that if Robert cooks, then Patricia is making tea, and that if Patricia makes tea, then Richard is driving a car we can infer that if Robert cooks, then Richard is driving a car via transitivity. Finally, from the fact that if it is sunny, then Robert is cooking, and that if Robert cooks, then Richard is driving a car we can infer that if it is sunny, then Richard is driving a car via transitivity, which contradicts that The fact that it is sunny does not imply that Richard is driving a car. Therefore, the answer is no.
