Work has been positively hellish of late, and I haven't been able to set aside the time necessary to rework a quiz for which I have gotten very detailed and thoughtful feedback. Is there a time limit on this? I want to thank the editors for their patience with us authors. So often we champ at the bit when we have submissions but then sit on corrections for a while. Anyway, I have not forgotten this one, I just haven't had time to get back to it.
