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 y for which y will go running if and only if y will read a book. For all y, y will go running if and only if y will read a book.
For all y, if y goes running, then y is reading a book. There is at least one y for which if y goes running, then y is reading a book. For all y, if y reads a book, then y is running. There is at least one y for which if y reads a book, then y is running.
