(I'm in the holdout juror camp).
I was firmly in that camp, at first hearing the question from the jury, but Jeralyn makes a point on the main board that maybe they are just being thorough and going through the instructions page by page, making sure they understand EXACTLY what each phrase means.
I still lean to one holdout, but nobody outside of the jury room has any way to know. The temptation to speculate is irresistible though.
