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, x_10 is not a scientist. For all x_10, if x_10 were a writer, then x_10 is running. There is at least one x_10 for which if x_10 goes running, then x_10 is a scientist. For all x_10, if x_10 were a scientist, then x_10 is running.
There is at least one x_10 for which x_10 will not go running. There is at least one x_10 for which if x_10 were a writer, then x_10 is a scientist. There is at least one x_10 for which x_10 will go running if and only if x_10 is a scientist. There is at least one x_10 for which x_10 is a scientist if and only if x_10 will go running.
