What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: Susan is reading a book or it is cold. For all x_14, x_14 will read a book if and only if x_14 will cook. Susan is not cooking.
For all x_14, if x_14 reads a book, then x_14 is cooking can be inferred via the universal biconditional elimination rule. For all x_14, if x_14 cooks, then x_14 is reading a book can be inferred via the universal biconditional elimination rule.
