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: If Susan were fast, then John is listening to a song. If it is windy, then Susan is a carpenter. For all z_4, if z_4 were a carpenter, then z_4 is fast. If Linda makes tea, then it is windy. If John listens to a song, then Linda is making tea.
If Susan were fast, then Linda is making tea can be inferred via the transitivity rule. If Linda makes tea, then Susan is a carpenter can be inferred via the transitivity rule. If John listens to a song, then it is windy can be inferred via the transitivity rule.
