*emerging from lurker mode*
Reading Gianny's post I thought where are the "Why" questions, since these are my favourite. Then I thought of probing, layer and question order. "I" see the What and How questions as the primary (lowest detailed) questions and should be asked when doing the first layer. The Who, When and Where will add more detail. And my favourite question "Why" will demonstrate true comprehension..... Just try a Why question on a math text.
