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_6, x_6 will not go running. For all x_6, x_6 is curious if and only if x_6 is a soldier. For all x_6, x_6 will go running or x_6 is not a soldier.
For all x_6, if x_6 were a soldier, then x_6 is running can be inferred via the universal rewriting rule. For all x_6, if x_6 were curious, then x_6 is a soldier can be inferred via the universal biconditional elimination rule. For all x_6, if x_6 were a soldier, then x_6 is curious can be inferred via the universal biconditional elimination rule.
