What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_14, if x_14 takes a plane, then x_14 is playing a game. For all x_14, x_14 is a writer. There is at least one x_14 for which x_14 will take a plane if and only if x_14 is a writer.
There is at least one x_14 for which if x_14 takes a plane, then x_14 is a writer. There is at least one x_14 for which if x_14 were a writer, then x_14 is taking a plane.
