What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_8, x_8 will cook or x_8 will not take a plane. There is at least one x_8 for which x_8 will cook if and only if x_8 is a carpenter.
For all x_8, if x_8 takes a plane, then x_8 is cooking. There is at least one x_8 for which if x_8 cooks, then x_8 is a carpenter. There is at least one x_8 for which if x_8 were a carpenter, then x_8 is cooking.
