Consider the following premises. For all x_7, if x_7 were a cashier, then x_7 is a carpenter. There is at least one x_7 for which x_7 will read a book. For all x_7, x_7 is poor if and only if x_7 is a carpenter. For all x_7, x_7 is poor or x_7 is a cashier. Can we infer the following from them? For all x_7, either x_7 will read a book or x_7 is a carpenter are not true.
 From the fact that for all x_7, x_7 is poor if and only if x_7 is a carpenter we can infer that for all x_7, if x_7 were poor, then x_7 is a carpenter. From the fact that for all x_7, if x_7 were poor, then x_7 is a carpenter, that for all x_7, if x_7 were a cashier, then x_7 is a carpenter, and that for all x_7, x_7 is poor or x_7 is a cashier we can infer that for all x_7, x_7 is a carpenter. Finally, from the fact that there is at least one x_7 for which x_7 will read a book, and that for all x_7, x_7 is a carpenter we can infer that there is at least one x_7 for which x_7 will read a book and x_7 is a carpenter, which contradicts that For all x_7, either x_7 will read a book or x_7 is a carpenter are not true. Therefore, the answer is no.
