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_1 for which if x_1 were a writer, then x_1 is a server. For all x_1, x_1 is a server or x_1 will not play a game. For all x_1, x_1 will play a game.
For all x_1, if x_1 plays a game, then x_1 is a server.
