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, x is not an artist. It is cold if and only if Jennifer is running. Elisabeth is an artist if and only if it is cloudy. Jennifer is not running.
If it is cold, then Jennifer is running can be inferred via the biconditional elimination rule. If Elisabeth were an artist, then it is cloudy can be inferred via the biconditional elimination rule. If Jennifer goes running, then it is cold can be inferred via the biconditional elimination rule. If it is cloudy, then Elisabeth is an artist can be inferred via the biconditional elimination rule. It is not cold can be inferred via the biconditional elimination rule.
