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_11, x_11 is curious or x_11 will not sleep. There is at least one x_11 for which x_11 will sleep. For all x_11, if x_11 were curious, then x_11 is making tea.
For all x_11, if x_11 sleeps, then x_11 is curious can be inferred via the universal rewriting rule.
