How hard can it be? Read a printed question from the wt magazine and then call on a person who is frantically waving their hand in the air so that the person can then read the printed "answer" from the wt magazine followed by everyone then nodding their heads in approval. Do not deviate from the printed material in the wt magazine. Scold any who dare exceed the 30 second time limit per comment. Do not exceed the 60 minute indoctrination period (aka watchtower study).
Done, a 12 year old could conduct!
just saying!
