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 Jennifer were an astronaut, then it is raining. It is raining or Jennifer is not happy. For all x_17, x_17 is an astronaut or x_17 is happy.
If Jennifer were happy, then it is raining can be inferred via the rewriting rule.
