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 z, z is curious. For all z, if z climbs a mountain, then z is drinking water. For all z, z is fast. For all z, if z were curious, then z is drinking water.
For all z, z will drink water can be inferred via the universal modus ponens rule. For all z, z is curious and z is fast can be inferred via the universal conjunction rule. For all z, z is fast and z is curious can be inferred via the universal conjunction rule.
