Consider the following premises. For all x_2, x_2 is poor or x_2 is curious. For all x_2, x_2 is an office clerk. For all x_2, x_2 is not poor. Can we infer the following from them? There is at least one x_2 for which either x_2 is curious or x_2 is an office clerk are not true.
 From the fact that for all x_2, x_2 is poor or x_2 is curious, and that for all x_2, x_2 is not poor we can infer that for all x_2, x_2 is curious. Finally, from the fact that for all x_2, x_2 is curious, and that for all x_2, x_2 is an office clerk we can infer that for all x_2, x_2 is curious and x_2 is an office clerk, which contradicts that There is at least one x_2 for which either x_2 is curious or x_2 is an office clerk are not true. Therefore, the answer is no.
