Consider the following premises. For all x_8, x_8 is bored. For all x_8, x_8 is a carpenter or x_8 is a server. For all x_8, x_8 is a carpenter if and only if x_8 is an office clerk. For all x_8, x_8 is not an office clerk. Can we infer the following from them? There is at least one x_8 for which either x_8 is a server or x_8 is bored are not true.
 From the fact that for all x_8, x_8 is a carpenter if and only if x_8 is an office clerk, and that for all x_8, x_8 is not an office clerk we can infer that for all x_8, x_8 is not a carpenter. From the fact that for all x_8, x_8 is a carpenter or x_8 is a server, and that for all x_8, x_8 is not a carpenter we can infer that for all x_8, x_8 is a server. Finally, from the fact that for all x_8, x_8 is a server, and that for all x_8, x_8 is bored we can infer that for all x_8, x_8 is a server and x_8 is bored, which contradicts that There is at least one x_8 for which either x_8 is a server or x_8 is bored are not true. Therefore, the answer is no.
