Consider the following premises. For all x_6, x_6 will not play tennis. For all x_6, if x_6 were an electrician, then x_6 is playing tennis. There is at least one x_6 for which if x_6 were an electrician, then x_6 is cooking. For all x_6, if x_6 cooks, then x_6 is an electrician. Can we infer the following from them? For all x_6, x_6 will cook.
 From the fact that for all x_6, if x_6 cooks, then x_6 is an electrician, and that there is at least one x_6 for which if x_6 were an electrician, then x_6 is cooking we can infer that there is at least one x_6 for which x_6 will cook if and only if x_6 is an electrician. From the fact that for all x_6, if x_6 were an electrician, then x_6 is playing tennis, and that for all x_6, x_6 will not play tennis we can infer that for all x_6, x_6 is not an electrician. Finally, from the fact that there is at least one x_6 for which x_6 will cook if and only if x_6 is an electrician, and that for all x_6, x_6 is not an electrician we can infer that there is at least one x_6 for which x_6 will not cook, which contradicts that For all x_6, x_6 will cook. Therefore, the answer is no.
