What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? There is at least one x_8 for which x_8 is sad if and only if x_8 will play a game. For all x_8, x_8 will sleep if and only if x_8 is a server. For all x_8, x_8 will play a game if and only if x_8 will sleep. For all x_8, x_8 is not a server.
For all x_8, if x_8 sleeps, then x_8 is a server. For all x_8, if x_8 plays a game, then x_8 is sleeping. There is at least one x_8 for which if x_8 were sad, then x_8 is playing a game. For all x_8, if x_8 were a server, then x_8 is sleeping. For all x_8, if x_8 sleeps, then x_8 is playing a game. There is at least one x_8 for which if x_8 plays a game, then x_8 is sad. For all x_8, x_8 will not sleep.
