Consider the following premises. There is at least one x_2 for which if x_2 takes a plane, then x_2 is a nurse. For all x_2, if x_2 were bored, then x_2 is taking a plane. For all x_2, x_2 is not a nurse. For all x_2, if x_2 takes a plane, then x_2 is bored. Can we infer the following from them? For all x_2, x_2 is bored.
 From the fact that there is at least one x_2 for which if x_2 takes a plane, then x_2 is a nurse, and that for all x_2, x_2 is not a nurse we can infer that there is at least one x_2 for which x_2 will not take a plane. From the fact that for all x_2, if x_2 takes a plane, then x_2 is bored, and that for all x_2, if x_2 were bored, then x_2 is taking a plane we can infer that for all x_2, x_2 will take a plane if and only if x_2 is bored. Finally, from the fact that for all x_2, x_2 will take a plane if and only if x_2 is bored, and that there is at least one x_2 for which x_2 will not take a plane we can infer that there is at least one x_2 for which x_2 is not bored, which contradicts that For all x_2, x_2 is bored. Therefore, the answer is no.
