The dates should not be close together like that because it becomes a guessing game. By spreading them apart, it at least makes the player ponder, and go through the elimation process. As for easy/intermediate, all difficulty levels are being accepted, then once initially played, are put in their own labeled question set. However, totally oblivious and those with no originality get sent back to the author.
When I write quizzes, the date options are a few years apart. When I write Single Questions, the dates are in separate decades because of the worldwide audience factor. I want to hang the player a carrot and make them *want* the answer. That's the spirit of the game. Try to be nice to the writers with your ratings.
