Consider the following premises. For all z_3, z_3 will play squash or z_3 will not listen to a song. For all z_3, z_3 will sleep if and only if z_3 will play squash. There is at least one z_3 for which if z_3 sleeps, then z_3 is playing squash. Can we infer the following from them? If we can, name the inference rule being used: For all z_3, the fact that z_3 listens to a song does not imply that z_3 is sleeping.
That contradicts the premises. Therefore the answer is no.
