Given
Laboratory mice that IHH → SC are used for research aimed at improving human health are usually kept in small cages.
Such an environment SC → ~N is neither normal nor healthy for mice.
Moreover, the reliability N → RR↓ of research using animals is diminished if those animals are not in an environment that is normal for them.
