Consider the following premises. For all x_7, x_7 is a cashier. For all x_7, x_7 will not go running. For all x_7, x_7 is not a cashier or x_7 will play squash. There is at least one x_7 for which x_7 is an electrician. Can we infer the following from them? For all x_7, either x_7 is an electrician or x_7 will play squash are not true.
 From the fact that for all x_7, x_7 is a cashier we can infer that for all x_7, x_7 is a cashier or x_7 will go running. From the fact that for all x_7, x_7 is a cashier or x_7 will go running, and that for all x_7, x_7 is not a cashier or x_7 will play squash we can infer that for all x_7, x_7 will go running or x_7 will play squash. From the fact that for all x_7, x_7 will go running or x_7 will play squash, and that for all x_7, x_7 will not go running we can infer that for all x_7, x_7 will play squash. Finally, from the fact that there is at least one x_7 for which x_7 is an electrician, and that for all x_7, x_7 will play squash we can infer that there is at least one x_7 for which x_7 is an electrician and x_7 will play squash, which contradicts that For all x_7, either x_7 is an electrician or x_7 will play squash are not true. Therefore, the answer is no.
