Not sure I entirely understand the question.
Are you saying that you are doing an FIC, and you are required to do a "long brief" on stalling? And that you're asking us what questions you could ask your "student" as an introduction to the subject?
If I've understood you correctly, then the thing to think about is what level of knowledge you expect your student to have at this stage. You must assume that he knows nothing about stalling, but that he understands all the previous exercises - effect of controls, s+l, climbing, descending and turning.
Bearing that in mind, you could ask your students what happens if they apply back-pressure to the controls. (Answer - aircraft pitches up. It also climbs - at least that's what the students have seen so far - although you're about to show them why this answer is less correct than the pitching up answer.)
Then you could point out that it must be possible to pitch up "too far" - an extreme example being pitching up to the vertical. Try to elicit from them that at some point, the wing will stop generating lift as it does in normal flight - but remember this isn't something you expect them to know already, so they'll need gently pushing in the right direction.
Then you can brief them on stalling.
If I've understood your question incorrectly, then I apologise, you'll have to clarify it further and I'll have another go.
