Consider the following premises. For all x_8, if x_8 plays squash, then x_8 is taking a plane. For all x_8, x_8 will make tea. For all x_8, if x_8 were an electrician, then x_8 is taking a plane. For all x_8, x_8 will play squash or x_8 is an electrician. For all x_8, if x_8 makes tea, then x_8 is playing a game. Can we infer the following from them? There is at least one x_8 for which either x_8 will take a plane or x_8 will play a game are not true.
 From the fact that for all x_8, if x_8 plays squash, then x_8 is taking a plane, that for all x_8, if x_8 were an electrician, then x_8 is taking a plane, and that for all x_8, x_8 will play squash or x_8 is an electrician we can infer that for all x_8, x_8 will take a plane. From the fact that for all x_8, if x_8 makes tea, then x_8 is playing a game, and that for all x_8, x_8 will make tea we can infer that for all x_8, x_8 will play a game. Finally, from the fact that for all x_8, x_8 will take a plane, and that for all x_8, x_8 will play a game we can infer that for all x_8, x_8 will take a plane and x_8 will play a game, which contradicts that There is at least one x_8 for which either x_8 will take a plane or x_8 will play a game are not true. Therefore, the answer is no.
