Consider the following premises. For all x_11, x_11 is rich or x_11 is an electrician. If it is cold, then Jennifer is not an electrician. For all x_11, x_11 is not rich. Can we infer the following from them? It is cold.
 From the fact that for all x_11, x_11 is rich or x_11 is an electrician, and that for all x_11, x_11 is not rich we can infer that for all x_11, x_11 is an electrician. From the fact that for all x_11, x_11 is an electrician we can infer that Jennifer is an electrician. Finally, from the fact that if it is cold, then Jennifer is not an electrician, and that Jennifer is an electrician we can infer that it is not cold, which contradicts that It is cold. Therefore, the answer is no.
