Instinct Test Questions

It looks like Ranger will be having an Instinct test in June. I was wondering what reactions are looked for and for typical reactions. Also is pedigree involved (his dam has her PT title http://www.plumridgetc.com/isis/herding.htm )? He has a very strong prey drive with birds, small animals, and even deer but we walk within feet of cows daily and he responds with cautious curiosity but has not gotten excited. Could either of these be a possible indicator of aptitude?

Thanks
