What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_10, if x_10 climbs a mountain, then x_10 is a writer. For all x_10, if x_10 were happy, then x_10 is rich. For all x_10, if x_10 were a writer, then x_10 is rich. There is at least one x_10 for which x_10 is rich if and only if x_10 will work. For all x_10, x_10 is happy or x_10 will climb a mountain.
