Nick:
The questions in the new exam are much harder and cover situations that might really happen in the real world. You need to read each question carefully. In the example at hand, the question clearly states, "clearly flashes two red Aces for all to see". Since "All" the players were able to see the hand, I believe that Rule 15 comes into play and all players have a responsibility to ensure the winning hand is paid.
OR
Are you now suggesting that the TDA needs to develop a rule that defines what constitutes a "Tabled Hand", I hope not? Have you never misread your hand, believed you were beat, and then had another player speak up and say you had the winning hand?
I believe this type of situation is exactly the reason we have Rule 15.
As to your reluctance to take the new exam, I suggest you read the question, choose your answer(s), then before selecting those answers, read the question one or two more times to make sure you caught all the little details that might make one situation different from another.
If the questions were all "vanilla" situations, anybody could take the exam and pass the first time. I think it is a HUGE improvement over the prior exam, in that you actually need to know something and think a bit in order to get the corrects answer(s).
