Some difference/thought between the questionnaire and the table for bear.

1. Based on the questionnaire, we don't know the age for the bear individually.
2. The bear table record is a single bear, means the "其他說明" is by bear and the "個體數" would not be stored on the bear table.

I think it should be fine if each entry of bear tabl maps one bear only. See below.

Good point. Thanks for the heads-up. According to this design, we will have shown_form to resolve this issue.
