Consider the following premises. For all x_6, x_6 is an office clerk or x_6 will drink water. For all x_6, x_6 is not an office clerk. For all x_6, x_6 is bored or x_6 will not drink water. Can we infer the following from them? There is at least one x_6 for which x_6 is not bored.
 From the fact that for all x_6, x_6 is bored or x_6 will not drink water we can infer that for all x_6, if x_6 drinks water, then x_6 is bored. From the fact that for all x_6, x_6 is an office clerk or x_6 will drink water, and that for all x_6, x_6 is not an office clerk we can infer that for all x_6, x_6 will drink water. Finally, from the fact that for all x_6, if x_6 drinks water, then x_6 is bored, and that for all x_6, x_6 will drink water we can infer that for all x_6, x_6 is bored, which contradicts that There is at least one x_6 for which x_6 is not bored. Therefore, the answer is no.
