Consider the following premises. For all x_14, x_14 is an electrician or x_14 is curious. For all x_14, x_14 is not an electrician or x_14 is fast. Jennifer is not curious. Can we infer the following from them? If we can, name the inference rule being used: Jennifer is not fast.
 From the fact that for all x_14, x_14 is an electrician or x_14 is curious, and that for all x_14, x_14 is not an electrician or x_14 is fast we can infer that for all x_14, x_14 is curious or x_14 is fast via universal resolution. From the fact that for all x_14, x_14 is curious or x_14 is fast we can infer that Jennifer is curious or Jennifer is fast via universal instantiation. Finally, from the fact that Jennifer is curious or Jennifer is fast, and that Jennifer is not curious we can infer that Jennifer is fast via disjunctive syllogism, which contradicts that Jennifer is not fast. Therefore, the answer is no.
