Consider the following premises. It is snowing or Karen is a bartender. Thomas is curious. It is not snowing. Jennifer is a politician. Can we infer the following from them? If we can, name the inference rule being used: Karen is not a bartender.
 From the fact that Thomas is curious, and that Jennifer is a politician we can infer that Thomas is curious and Jennifer is a politician via conjunction. Finally, from the fact that it is snowing or Karen is a bartender, and that it is not snowing we can infer that Karen is a bartender via disjunctive syllogism, which contradicts that Karen is not a bartender. Therefore, the answer is no.
