I recently landed on a youtube video about this question and intrigued about its uncertainty in detail in every aspect. Hence i thought it would be a challenge to solve it and decided to work on it.
For those who dont know about the question can watch this video to know it better.
I thought we can exploit the details of the question to workaround and come up with a decent answer to this question.
My take is as follows.
Condition 1: We can ask only three yes/no questions
Condition 2: Each question should be dedicated to only one god.
Condition 3: You can ask multiple questions to the same god.
Let us choose first god and ask the first question
1) Are you ARR?
Repeat the question again and again to confirm it is not ARR. Since you will get different responses for the same question. (Remember, Condition 1 limits the number of questions can be asked but not from the number of times it can be asked.)
If the God is ARR, We can skip to the 2nd god, otherwise we can stick with the current god.
Then we can ask the following questions.
2) Is anyone of you two is ARR? (1,2 or 2,3)
3) Did you say ozo/zulu(based on the previous response) to my previous question.
If the answer is same as the previous question. Then I am talking to Tee(next to him is ARR and next to ARR is Eff)
If the answer is different, then i am talking to Eff(next to him is Tee and next to Tee is ARR)
And we can deduce what is ozo and zulu based on our previous deductions.
Note : We can switch subject names in the question based on multiple scenarios to deduce the answer. I didn't want to confuse you further. I would like you to get the logic behind the questionnaire. So that you can play out different scenario with the question pattern and blow out your mind.
Note : The objective of the problem is to find which is which god and what are the equivalents of yes and no. without exhausting the number of questions.
Then we can talk to the most reliable god Tee to get a free uplift from their planet.
I believe this would be a better answer. Since other answers are mostly speculative and is mostly vulnerable against ARR.
Why I dont buy other answers?
It is said ARR is Random. Which means ARR can provide any answer (True, False, True, True, False). Hence you might end up in a scenario where ARR pretty much fake like it is TEE or EFF. Your well tailored question might be lost on ARR and your number of chances even get reduced to 2 or 1. Definitely, there is no logical solutions that can filter out ARR within 3 attempts.
And there is no guarantee that the first one you interact would not be ARR.
Last but best part,
It took me 3 hours to completely understand and come up with a mere solution. And the video asks me to come up with a solution is 3 seconds.
Anyway guys(Ted ed). Good Job on your video. 3 hours well spent.
