This question already has an answer here:
"List" questions can be bad if they generate an endless list of answers, with no answer better than another. Such a question might be, "Who is the best general of all time?"
But could a "list" question be acceptable if it is a factual, "short-list question?" Example: Which generals were senior to Robert E. Lee in the Confederate army, and were they as famous? (List) answer: 1) Samuel Cooper, based on age, but he was an overaged "figurehead" who was given make-work duties like inspecting forts. 2) Albert Sydney Johnston. Promoted earier, and considered by some historians to be better than Lee, but we'll never know, since he was killed early at Shiloh.
Is one kind of list question better than the other?
