Consider the following premises. James is playing a game or James is a scientist. James is a sailor. If it is late, then James is not a scientist. James is not playing a game. Can we infer the following from them? If we can, name the inference rule being used: It is late.
 From the fact that James is playing a game or James is a scientist, and that James is not playing a game we can infer that James is a scientist via disjunctive syllogism. Finally, from the fact that if it is late, then James is not a scientist, and that James is a scientist we can infer that it is not late via modus tollens, which contradicts that It is late. Therefore, the answer is no.
