Consider the following premises. Robert is rich. David is not playing tennis. David is playing tennis or it is windy. Robert is making tea and it is late. Can we infer the following from them? If we can, name the inference rule being used: It is not windy.
 From the fact that Robert is making tea and it is late we can infer that Robert is making tea via simplification. Finally, from the fact that David is playing tennis or it is windy, and that David is not playing tennis we can infer that it is windy via disjunctive syllogism, which contradicts that It is not windy. Therefore, the answer is no.
