Consider the following premises. James is a taxi driver or it is not snowing. If James were a taxi driver, then it is windy. If it is windy, then it is snowing. Can we infer the following from them? If we can, name the inference rule being used: If is not true that it is windy if and only if James is a taxi driver.
 From the fact that James is a taxi driver or it is not snowing we can infer that if it snows, then James is a taxi driver via rewriting. From the fact that if it is windy, then it is snowing, and that if it snows, then James is a taxi driver we can infer that if it is windy, then James is a taxi driver via transitivity. Finally, from the fact that if it is windy, then James is a taxi driver, and that if James were a taxi driver, then it is windy we can infer that it is windy if and only if James is a taxi driver via biconditional introduction, which contradicts that If is not true that it is windy if and only if James is a taxi driver. Therefore, the answer is no.
