Consider the following premises. If James were an office clerk, then it is windy. James is an office clerk. If it is late, then it is not windy. It is cold. Can we infer the following from them? If we can, name the inference rule being used: It is late.
 From the fact that if James were an office clerk, then it is windy, and that James is an office clerk we can infer that it is windy via modus ponens. Finally, from the fact that if it is late, then it is not windy, and that it is windy we can infer that it is not late via modus tollens, which contradicts that It is late. Therefore, the answer is no.
