What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all y, if y were a sailor, then y is running. For all y, if y works, then y is a sailor. For all y, if y goes running, then y is working. For all y, if y goes running, then y is a sailor. For all y, y will not go running.
For all y, y is not a sailor. For all y, if y were a sailor, then y is working. For all y, if y works, then y is running. For all y, if y goes running, then y is a sailor. For all y, y is a sailor if and only if y will go running. For all y, y will go running if and only if y is a sailor.
