Consider the following premises. If it is windy, then Jennifer is not playing a game. It is windy or Thomas is working. Jennifer is playing a game. Can we infer the following from them? If we can, name the inference rule being used: Thomas is working.
 From the fact that if it is windy, then Jennifer is not playing a game, and that Jennifer is playing a game we can infer that it is not windy via modus tollens. Finally, from the fact that it is windy or Thomas is working, and that it is not windy we can infer that Thomas is working via disjunctive syllogism. Therefore, the answer is yes.
