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: For all x_10, x_10 is a lawyer if and only if x_10 will drive a car. For all x_10, x_10 will read a book or x_10 is a lawyer. For all x_10, x_10 will not drive a car. For all x_10, x_10 is a musician. For all x_10, x_10 will not read a book or x_10 is a carpenter.
For all x_10, x_10 is a lawyer or x_10 is a carpenter can be inferred via the universal resolution rule. For all x_10, if x_10 were a lawyer, then x_10 is driving a car can be inferred via the universal biconditional elimination rule. For all x_10, if x_10 drives a car, then x_10 is a lawyer can be inferred via the universal biconditional elimination rule. For all x_10, x_10 is not a lawyer can be inferred via the universal biconditional elimination rule.
