That actually depends on the Examiner's interpretation/execution of:
IV. AREA OF OPERATION: PREFLIGHT LESSON ON A MANEUVER TO BE PERFORMED IN FLIGHT
From the FAA pubs in the references, which form the substance of the TASK, it is pretty clear that the FAA expects a lesson to be taught from a formalized lesson plan.
It used to be you were expected to be able to do this "on the fly" - make it up on the spot. The Examiner, after a reasonable technical Q&A, would take a "30-minute coffee break", during which time you would make up a lesson plan for a particular maneuver, and then present it from the lesson plan. And some still do this, I hear, but mostly they expect a pre-prepared group of lesson plans. YMMV
