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_14, x_14 will sleep. For all x_14, x_14 will cook. There is at least one x_14 for which x_14 is happy and x_14 is curious.
There is at least one x_14 for which x_14 is happy can be inferred via the existential simplification rule. There is at least one x_14 for which x_14 is curious can be inferred via the existential simplification rule. For all x_14, x_14 will sleep and x_14 will cook can be inferred via the universal conjunction rule. For all x_14, x_14 will cook and x_14 will sleep can be inferred via the universal conjunction rule.
