What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? There is at least one x_7 for which x_7 is fast if and only if x_7 is poor. For all x_7, x_7 is not poor. For all x_7, x_7 is fast or x_7 will go running.
There is at least one x_7 for which if x_7 were fast, then x_7 is poor. There is at least one x_7 for which if x_7 were poor, then x_7 is fast. There is at least one x_7 for which x_7 is not fast.
