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: There is at least one x_6 for which x_6 will make tea. For all x_6, x_6 will not play squash or x_6 is curious. For all x_6, x_6 will play squash or x_6 is a carpenter. For all x_6, x_6 is not a carpenter.
For all x_6, x_6 is a carpenter or x_6 is curious can be inferred via the universal resolution rule.
