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: Patricia is an artist or Patricia is not making tea. If Patricia were an artist, then it is snowing. If it snows, then Patricia is making tea.
If Patricia were an artist, then Patricia is making tea can be inferred via the transitivity rule. If Patricia makes tea, then Patricia is an artist can be inferred via the rewriting rule.
