Consider the following premises. Susan is a poet. For all x_13, if x_13 were a nurse, then x_13 is playing a game. For all x_13, if x_13 takes a plane, then x_13 is playing a game. For all x_13, x_13 is a nurse or x_13 will take a plane. Can we infer the following from them? For all x_13, either x_13 is a poet or x_13 will play a game are not true.
 From the fact that for all x_13, if x_13 were a nurse, then x_13 is playing a game, that for all x_13, if x_13 takes a plane, then x_13 is playing a game, and that for all x_13, x_13 is a nurse or x_13 will take a plane we can infer that for all x_13, x_13 will play a game. From the fact that Susan is a poet we can infer that there is at least one x_13 for which x_13 is a poet. Finally, from the fact that there is at least one x_13 for which x_13 is a poet, and that for all x_13, x_13 will play a game we can infer that some poets will play a game, which contradicts that For all x_13, either x_13 is a poet or x_13 will play a game are not true. Therefore, the answer is no.
