[@CubicSagacity]

Long-winded breakdown of why you don't need to know the exact meaning of "OZO" and "ULU", and why Arr doesn't prevent a solution (the first part is pretty much a reiteration of the video, but at the end I try to explain my understanding of it): Tee (T) tells the truth Eff (F) tells a lie Arr (R) answers randomly Question: "If I asked you whether 2+2=4 (known true), would you say 'OZO' (unknown meaning)?" IF "OZO" = "Yes" AND "ULU" = "No" Answers: T: "OZO" F: "OZO" (He would say "ULU" to the embedded question, so he denies this and says "OZO".) IF "ULU" = "Yes" AND "OZO" = "No" Answers: T: "OZO" F: "OZO" (Yes, he would say "OZO" to the embedded question, so he denies this and says "OZO".) Like this: - Q to F: "Does 2+2=4?: - F: "OZO" - Q to F: "If I asked you whether 2+2=4, would you say 'OZO'?" - F: "OZO" (Must lie about his previous answer and deny that he WOULD say "OZO", but because "OZO" means "No" in this example, he uses the word "OZO" in order to deny it.) Question: "If I asked you whether 2+2=5 (known false), would you say 'OZO' (unknown meaning)?" (Assuming the year is not 1984) IF "OZO" = "Yes" AND "ULU" = "No" Answers: T: "ULU" F: "ULU" IF "ULU" = "Yes" AND "OZO" = "No" Answers: T: "ULU" F: "ULU" Question: "If I asked you whether the overlord on my left is Arr (unknown), would you answer 'OZO' (unknown meaning)?" IF "OZO" = "Yes" AND "ULU" = "No", AND Arr IS to the left Answers: T: "OZO" F: "OZO" IF "ULU" = "Yes" AND "OZO" = "No", AND Arr IS to the left Answers: T: "OZO" F: "OZO" IF "OZO" = "Yes" AND "ULU" = "No", AND Arr IS NOT to the left Answers: T: "ULU" F: "ULU" IF "ULU" = "Yes" AND "OZO" = "No", AND Arr IS NOT to the left Answers: T: "ULU" F: "ULU" ~ So you aren't finding out the meaning of the words, but you ARE determining the validity of your embedded question. You know that an answer of "OZO" from Tee or Eff means that the embedded question is true, and an answer of "ULU" from them means that the embedded question is false. On to the matter of determining order. Posed to the middle alien, the first question is this: "If I asked you whether the overlord on my left is Arr (unknown), would you answer 'OZO' (unknown meaning)?" This question isn't about confirming who IS Arr, it's about confirming who IS NOT Arr. If Arr is on either side, the first alien you're talking to must be Tee/Eff and you'd then know for sure where Arr is based on their answer. If Arr is in the middle, then the answer he gives would still point you in the correct direction because he ISN'T on either side. If Arr says "OZO" randomly, you would now be choosing between left and middle alien. If Arr says "ULU" randomly, you would be choosing between right and middle alien. Either way, you've determined the two spots where Arr COULD be and, more importantly, the one where he definitely COULDN'T be. Originally, I was confused because it seemed like this solution required starting with Tee/Eff for sure, and already knowing which side Arr is on so you can formulate your question accordingly and know that you wouldn't be getting a random answer. However, getting a random answer isn't as much of a wrench in the works as I first thought, because that in itself can be used to make an elimination as Arr can't be in two places at once. I'm not claiming to be an expert logician or anything and I admit that I could definitely be wrong, but that's my understanding of this riddle. In my opinion, the hardest part to understand is the fact that Arr answering randomly doesn't prevent you from being able to find the correct answer, so I decided to post how I worked through it in case it might be a help to anyone else. :)

[@CubicSagacity]

@@JustAnotherHumanBeing980 I know! It's crazy how hard it is to make one's brain work through it 😂 I would say the two biggest things are that: 1) Tee or Eff answering with "OZO" for sure means your embedded question is true, while an answer of "ULU" from Tee or Eff for sure means the embedded question is false 2) Arr can't be in two places at once. If Arr is in the middle and he answers your question randomly, he's telling you that Arr is not on a certain side, which is true because you're talking to him right now in the middle. While this information may come in the form of him lying and saying Arr IS located on a certain side, that still gets you in the correct direction because you've eliminated a position where he couldn't be either way. (If, answering randomly, he indicates that Arr is on the left, you'll eliminate the possibility of him being on the right. It is true that he is not on the right: he is currently in the middle.) And if you're talking to Tee/Eff in the middle, then your problems are solved anyway hahah Maybe that helped a little? Hopefully it did 😅

but it sure is unfortunate that we crash landed on a planet with 3 aliens that have certain tendencies to lie and tell the truth, and that we know the entire alien language except for yes and no, and that we can only ask three yes or no questions, and that the aliens only respond with ozo and ulu.

[@edgemadefoxe367]

The original one was about gods and the gods understand your language but can only reply with Olu or Ozo

[@markimbing8018]

2:15 It would be better to explain this by not using ozo or ulu. For example: “If I asked you if 2+2=4, would you say yes?” To the embedded question, Tee would say yes. Tee would reply to your question and say “Yes, I would say yes if you asked me if 2+2=4.” The rules state that Eff always lies. It doesn’t imply that Eff would say the opposite of Tee or vice versa. To the embedded question, Eff would say no. If he said “No, I would say no to 2+2=4.”, that means he said something true, which contradicts his rule of lying. Instead, he would lie and say “Yes, I would say yes to 2+2=4.” Reverse example: “If I asked you if 2+2=4, would you say no?” To the embedded question, Tee would say no, so Tee replies and says “No, I would say yes to 2+2=4.” Eff, again, would tell the truth and break his lying rule if he says “Yes, I would say no to 2+2=4.” So he would have to say “No, I would say yes to 2+2=4.”

Danke

[@jlyaaburnee]

an explanation; the gist of this whole riddle is to emphasize the power of a double negative. we can obtain all the information we need from these gods using double negatives, without even knowing the meaning of the answer or the how truthful it is. understanding why tee and eff will give their given answers is the easy part, at least when we are asking questions we know whether or not are true or false. i think when we try to get answers we dont already know, thats when it gets difficult and we get lost in the sauce. instead of ozo and ulu, ill use x and y for simplicity, with ozo=x and ulu=y. if the embedded question is true, no matter what x or y is, what we ask is going to either give a double positive or negative. (if i ask you whether or not the sky is blue, would you answer x?) when x=yes tee -> x! eff -> x! (to the question itself, it would answer y) when x=no tee -> x! eff -> x! (lies about lying to the embedded question.) the important part here is to realize they both responded x because the embedded question was true. what would happen if it was false? (if asked you whether or not the sky is red, would you answer x?) when x=yes tee -> y! eff -> y! (would say x to embedded question) when x=no tee -> y! eff -> y! (would say x to embedded question.) the takeaway is _when our embedded question is true,_ irregardless of what x or y is, we will get that same variable we put in our question back from them. thats the only thing all that x and y mess above told us thats important. now that we know what the answers to true and false questions look like, we can use the gods responses to see whether or not their responses match a true or false embedded statement. look; if i asked you whether *abc,* would you answer x? if a god responds -> x then we have proved above that abc must be a true statement, and we learned something new! if a god responds -> y then we have proved that abc must be false. just scroll up! now we use statements on the position of the gods to get them to sell each other out! but do not lost sight of the big picture- we dont care what ozo and ulu are! we dont need to! it doesnt matter! what matters is _if your embedded question is true!_

I’m just happy to say, despite not coming up with the answer, I was finally able to completely Understand the solution after some time. It took a while thought as they brush through that solution so fast without explaining in detail. It’s pretty remarkable for someone to come up with the full answer. In hindsight, it makes so much sense that question 1 must isolate one that isn’t the random answerer - as no other questions can contain information until you have at least that. But still.. even making that discovery, coming up with that first question is very difficult to do.

That final question is basically choosing between learning what Ozo and Ulu actually mean or getting a last useful answer out of Tee. I think I would ask the 2+2=4 to know what Ozo means. The first time I watched this video I totally didn't fully understand the solution, so at the end I thought Tee's answer was useless. But no, Ozo means our conjecture is correct, so it will be a long way to Earth (we know that now), we just don't know yet what Ozo actually means. I really love this riddle.

[@PJSM94]

It's really not that difficult. If I asked you, "(insert hypothetical question here)," *would you reply "OZO"?* -If the hypothetical is true, Tee AND Eff will ALWAYS reply OZO -If the hypothetical is false, Tee AND Eff will always reply ULU. However, if we swapped out OZO for ULU in our question, everything would be the opposite. Like this: If I asked you, "(insert hypothetical question here)," *would you reply "ULU"?* -If the hypothetical is true, Tee AND Eff will ALWAYS reply ULU -If the hypothetical is false, Tee AND Eff will always reply OZO. Whatever you decide to put in at "would you reply _____?" will always be the response if the hypothetical is true. Here's an example: If I asked you, "Does 2+2=4," would you reply *"OZO"?* The answer will always be OZO if you're asking Tee or Eff. You could swap out OZO for ULU, though. If I asked you, "Does 2+2=4," would you reply "ULU"? Again, Tee and Eff will always reply ULL since the hypothetical is true. If it's false, they'll answer with the opposite word that's in the question. Let's assume we're talking to Eff. If I asked you, "Are you Eff," would you reply "OZO"? Assume OZO = TRUE. You can essentially rewrite the question: If I asked you, "Are you Eff," would you answer "yes"? Think about what Eff's reply will be, given that he always lies. If he says "yes, I would say yes," he's lying about answering yes to the other question. Which is what he would do.. he's Eff. But if he replied "no," or the opposite to the word in the question," he would essentially being saying, "no, I would not say yes to that question." That's actually a true statement. He's being honest that he would like to us. So, he has to reply with OZO, given that is the word in the question and the hypothetical is true. So even if that doesn't make sense, you just have to understand that whatever word is in the question, OZO or ULU, that will be the answer IF the hypothetical is *true*, and if the hypothetical is false, the opposite word that isn't in the question will be there answer. When we ask the alien in the middle: If I asked you "Is Are to my left," would you reply OZO? -We have 3 options. We're either talking to Eff, Tee, or Arr. Let's say we get the reply ULU. We know that ULU is the opposite to the word in the question, OZO. So, IF we are talking to Tee or Eff and we get the response ULU, we know that the hypothetical is false. This means, Arr isn't on the left. But if we are talking to Arr, well that means he is also still not on the left, because he's in the middle. IF we get the reply ULU, Arr is eliminated from the left.. meaning it's either Eff or Tee, so we won't get a random answer as a possibility when we ask that alien a question. So, go to the left most Alien. If I were to ask you, "Are you Tee," would you reply OZO? An ozo reply indicates that the hypothetical is true. If it's true, then we are talking to Tee. If it's false, we are talking to Eff. Let's say it's true and we get an ozo reply, so it's Tee. We know one Alien. Now, just ask Tee this: If I were to ask you, "Is the alien in the middle Arr," would you reply OZO? An OZO reply means the middle alien is Arr. An ULU reply means the Alien is Eff. There, you solved it.

[@canaDavid1]

@@PJSM94 *oh ok*

[@Ian.langford823]

Here's by far the easiest way to understand this: To help you understand let's say Ozo means yes and Ulu means no. Then let's say the aliens in order from left to right are: Tee | Eff | Arr The solution to the problem is tricking Eff into always telling the truth by using a double negative. Here's how: If you asked him "is the god to your left Arr?" he would lie and say yes(ozo). So if you instead say "if I asked you if the god to your left were Arr, would you say yes(ozo)?" Since he indeed would have, he would lie again and say no(ulu). We just tricked him into telling the truth. Now if Tee and Eff were switched then the exact same thing would've happened. If you asked Tee "is the god on your left Arr?" he would've told the truth and said no(ulu). So if you asked him "if I asked you if the god on your left were Arr, would you say yes(ozo). He would not have so he would still say no(ulu). So whether Tee or Eff is in the middle either one would've told the truth. So what if you're speaking to Arr? Well then that would mean the one on the left couldn't be Arr of course. The whole point of the first question is just to figure out which of the three is NOT Arr. Which you now know is the one on the left. So now you know that the one on the left is either Tee or Eff, and you know how to trick Eff into telling the truth. So now you ask the one on the left "if I asked you if you were Eff, would you say yes(ozo)?" since it's Tee he would say "no(ulu)". So now you know it's Tee. So now you ask Tee again "is the one in the middle Arr?" Tee would say no(ulu) so you would know the one in the middle must be Eff which means the one on the right must be Arr. Now the reason you don't need to know what Ozo or Ulu means is because you just need to see if they respond with the same word you used or not. If you ask the question with Ozo and they answer with Ozo then they're basically saying yes. If they respond with Ozo when you say Ulu it means no, if they respond with Ulu when you say Ozo it means no. If they respond with Ozo when you say Ozo it means yes. If they respond to Ulu with Ulu it means yes. This whole riddle is basically using negatives and positives from math to solve the problem. If you use a negative, and they use a positive then the solution is negative, or false. If you use a negative and they use a negative then the solution is positive, or true. So now look at the question again "If I asked you if the god on the left is Arr, would you say Ozo?" He replies "Ulu". So you know he's saying the god on the left is NOT Arr. Either he's telling the truth or he IS Arr, either way you know the god on the left isn't Arr, which allows you to figure out the other two. Hope this helps.

I just realised that you could determine which word means "yes" and which word means "no" with your final (fourth) question There are several ways to go about this, but the simplest is asking Tee whether or not he is Tee Do not add a hypothetical statement to this question, simply ask Tee, "Are you Tee?" Since we know the question is true and Tee always answers truthfully, there are only two possible outcomes: 1) Tee answers "ozo". Therefore, "ozo" means "yes" and "ulu" means "no" 2) Tee answers "ulu". Therefore, "ulu" means "yes" and "ozo" means "no"

[@roshan081990]

So the part that is confusing is about Ozo being either “Yes” or “No”. But the thing is that doesn’t matter. What is important to know is that receiving Ozo equates to the imbedded question being “True” and receiving Ulu equates to “False”. True and False are not the same as Yes and No, respectively. Hence, the meaning of the words does not matter. So regardless if you ask the question to Tee, Eff or Arr, if you receive Ozo as the answer it means the imbedded question is True and if the answer is Ulu that means it’s False.

[@MichaelDarrow-tr1mn]

except if you're talking to arr, arr completely skips that and just picks at random

[@alvedonaren]

@@MichaelDarrow-tr1mn But the whole point about the first question is to guarantee that you ask the secodn and third questions to someone who isn't Arr. If Arr is on one of the sides then the first question will direct you to the side whe he isn't. If Arr is in the middle then the first question doesn't matter because you're always asking the second and third questions to one of the sides.

Its actually not overly difficult to solve or understand the answer if you have a good knowledge of bool's algebra and good experience in problem solving. Otherwise, however, it is incredibly difficult

[@Playblueberry]

In fact, there IS a way to find out the translation of these words. After we have found out who is who, without wasting the last question to find out what we won't understand, we ask either Tee or Eff: "Does Tee always tell the truth?" / "Does Eff always lie?" Tee's answer is always true, and since we ourselves know the answers to our questions, Tee's answer translates to "yes". Accordingly, if we ask Eff, his answer translates to "no".

[@legendaxicad._]

Ozo = x^2 x pi. No solution. But.... if I told you there was, what would it be, yes or no? Ozo means yes, while ulu means no. This is solved by asking if Tee's name is Tee, and whatever he responds with is yes. By mentioning his name, he will respond truthfully. He responds Ozo, which is now yes. This identifies Tee, and solves for Ozo. Now, you mention Eff and pick a answer where you know if it is yes or no. This finds Eff and can lead to maybe discoveries and other possibilities. You then find Arr, and ask Tee if you this is the correct overlords' names.

Basically this puzzle consists of two logics. The first one, no matter what ozo or ulu means, the god will always respond with the one you picked as "yes", and the opposite as "no". The second one is to create a logic that we can use to eliminate Arr while finding out who is lying. Because each question is trying to find Arr, we will have enough information to guess which one is the random Arr even if Arr messed up our first question from the start.

The one saying "no" or lying, realizes he is lying and tells the truth. Seriously. Is 2+2=4? Truth - yes Liar - no...but realizes he is lying so says "yes" for some reason

[@hardcoregayyaoilover]

since he lies, he lies to himself...?

[@arcuesfanatic]

If asked "If I asked you if 2+2=4, would you respond 'ozo'?", it doesn't matter what "ozo" and "ulu" actually mean. Tee's response would be straight forward. If "ozo" meant yes, he would truthfully reply "yes", since he would in fact say yes to the condition. Eff, however would actually respond no to the condition, due to him always lying. So since he would actually respond "no", he instead responds "yes" to being asked if he would respond "yes" to the question. This means in either case, they would both respond "ozo", since we assume here "ozo" means "yes." Let's assume instead that "ozo" means "no." In that case Tee, who would normally respond "yes" to the condition, responds "no", since he would not say "no" to the condition. Eff, on the other hand, would normally say "no" to the condition. Therefore, if asked if he would respond "no", he would lie and say "no" to the question, since he actually would say "no" to the condition. Either way, the would still respond "ozo" to the question, based on our assumption. Because of all of this, no matter if we ask Tee or Eff, or if "ozo" means "yes" or "no", both of them will respond "ozo" if the condition is true, and "ulu" if the condition is false. This doesn't help us with Arr, since his response is random, but that's what the rest of the video is for.

[@davidwallace3933]

I figured out another 2-question solution using another special question, and this solution is better than my last. This solution exploits the same 2 facts: 1. Nobody knows what Arr would say because he answers randomly, and 2. Both Tee or Eff cannot answer ozo or ulu if he doesn’t know the answer. Let’s label the aliens from left to right as A, B, and C. The strategy is to find Arr first. Ask A, “If I asked him (pointing at B) if he were Tee, would he say ozo?” If A cannot answer ozo or ulu, then B must be Arr; A cannot answer if he does not know how B would answer. If you’re lucky in finding Arr right away, then ask C, “If I asked him (pointing at A) if he were Tee, would he say ozo?” If C answers ozo, then A is Eff and C is Tee, but if C answers ulu, then A is Tee and C is Eff. If you were not so lucky to find Arr yet, then he’s either A or C. Ask B, “If I asked him (pointing at C) if he were Tee, would he say ozo?” If B cannot answer ozo or ulu, then C must be Arr and A’s prior answer is all you need. If A answered ozo, then A is Tee and B is Eff, but if A answered ulu, then A is Eff and B is Tee. On the other hand, if B answers ozo or ulu, then A must be Arr. If B says ozo, then B is Tee and C is Eff. If B says ulu, then B is Eff and C is Tee. Please let me know what you think.

It's not super intuitive; you just have to check each case.

F would answer 2 + 2 = 4 with no, but what you're basically asking is "do you tell the truth?" He'd lie and say yes. Ask F: If I asked you if 2 + 2 = 4, would you say no? What you're basically asking is "Would you tell a lie?" He'd lie and say no. If you notice, in each case the premise of the question you're asking is true. No matter what word you use, yes or no, or whether you're asking T or F, the alien would match that word. That's the hardest part of the logic puzzle; the rest is elimination.

But you started your explanation from assuming the meaning to ozo and ulu, which is very confusing and somehow contradictory to the riddle's core essence.

@@Hange. If "statement is true", would you answer ozo? Assuming ozo means yes: Tee: Statement is true, so ozo. Eff: Statement is true, but eff will give false answer, so he would have answered ulu to the statement, but the point of the question isn't whether the statement is true or false, it's on which answer they'll give, since eff will answer ulu, he changes the answer to ozo. Assuming ozo means no: Tee: Tee would've answered yes (ulu) it's true, so he answers no (ozo). Eff: Eff would've answer no (ozo), so his truthful answer would be ulu to the entire question, eff being eff he changes the answer to ozo. Now if "statement is false", would you answer ozo? If ozo means yes: Tee would say no (ulu) because it's false. Eff would say ozo to the statement, so when he's asked if he would answer ozo, he falsifies and answers ulu. If ozo means no: Tee answers ulu (yes) because the statement is false. Eff would say ulu to the statement, so when asked if he would answer ozo, he falsifies and answers ulu. From both scenarios we can conclude that if the statement is true, tee and eff would answer ozo (same answer you include in your whole question), if it's false, they'll both answer ulu (different answer in your whole question). Then you can work your statements around eliminating arr, so you can get straight forward answers from either Tee or eff.

But inside those 10 times, he repeated ozo 3 times straight. If he casually does this on your 3 chances to question (wich he could, because it's random every time) he would still maintain the 50/50 proportion, but would've answered you 3 times the same thing, so you cannot trust arr to give you different answers every time: randomness of that kind in practice tends to a distribution, but in theory it could be always ozo infinite times, or an least 3 times.

If B is random, ask A if "ozo" is a positive answer/affirmative/confirmation: - If they mean yes and are telling the truth, they'll say ozo. - If they mean yes and are lying, ozo means no but they're the liar, so they'll say ulu. - If they mean no and are telling the truth, ozo means no, so they'll say ozo. - If they mean no and are lying, ozo means yes but they're the liar, so they'll say ulu.

Also, I am not sure if your interpretation is correct, as if arr always decided to tell either the truth of a lie, you could get information out from him using the same method that you use with tee and eff, which isn’t what the problem wanted in my understanding, considering the solution.

[@Kehlsteinhaus7]

the answer is give each one an artifact, check and see if they are appeased, if not, load from previous save file, and try another combination of artifacts there are 3 artifacts (or sequences) to choose from, should take 4 or 5 tries. then exit planet.

[@nickcampbell3812]

I didn't realize that you started by knowing which artifact went to which Overlord by name. I thought after identifying the Overlords, you would still have to try to figure out which artifact belongs to which name. Kind of makes me wonder how many questions you would need for this additional task.

When you ask the alien lords whether ozo is yes or no Alien lords: well yes but actually no

[@cat1554]

Science Theorizer Well ozo but actually ulu

[@catserfer4753]

Good one

[@KommandoCraftLP]

it is funny how at the end both you and the narrator have forgotten the key premise to this riddle. If you would ask Tee (or Eff, doesn't matter actually) the question "If I would ask you, whether Ozo means yes, would you answer Ozo?" and they would actually answer Ozo, then you know that your hypothetical question was true and Ozo really means yes. If they reply with Ulu your question was wrong and Ozo means no: "proof": suppose O=⊤ (yes/true/top): F(F(O=⊤)=O) F(F(⊤=⊤)=⊤) F(F(⊤)=⊤) F(⊥=⊤) F(⊥) ⊤ suppose O=⊥ (no/false/bottom): F(F(O=⊤)=O) F(F(⊥=⊤)=⊤) F(F(⊥)=⊤) F(⊤=⊤) F(⊤) ⊥

[@KommandoCraftLP]

@Floki fair enough, though from the six rules you are not limited on what to ask the aliens as long as it is a yes or no question, so my proposed question is still one that she could ask. In other versions of this riddle the introduction is done a bit different and the aliens do understand your language, but can only talk in their own. I guess that is where the ambiguity in the rules emerges from. Alternatively you could also ask Tee, after having identified all aliens, if he is Tee and his answer will tell you whether Ozo or Ulu means yes.

[@encyclopediaamericana7234]

They'd be like: "oh you still don't know?" Lmao!

[@theodriggers549]

“Tee, if I asked you whether I have green eyes, would you answer “ozo”? *Tee answers ozo”

[@lindsayantwine1097]

Well, friends and neighbors, my brain is so burnt out and exhausted til I wouldn't even try to figure any of this out. I'd just submit to the three overlords and hope for the best. 👍💯

[@helixzenith]

For the fourth and final question when you leave, ask Tee: “Is 2+2=4” If oso means yes, Tee would say oso. If oso means no, Tee would say ulu. You would finally be able to find out what the words mean. It wouldn’t really accomplish anything other than you being fully fluent in the alien language though.

[@reeven1721]

It gives you a Steam achievement if you unlock the full language.

[@avinlia2029]

…Unless this whole time the aliens didn’t know how to do math…

[@marcusscience23]

The riddle will make a tiny bit more sense if: you can ask in your own language and the aliens will understand, but they will only answer in their own language which you don't know.

[@kurax9115]

Also only works If aliens have the same syste on maths

[@yettispaghetti6784]

Tbh you could just ask another hypothetical question to find out if it's a long way to Earth without knowing if ozo is yes or no. "Tee, If I asked you 'is it a long way to Earth?' Would you answer ozo?" If ozo, statement is true, it's a long way till Earth. If ulu, hooray! Earth isn't that far away!

[@rockdrake3176]

Just put down the artifacts in front of the three over lords and say in alien: “Take the one you want”

Some versions of this puzzle say that they understand you but will always answer in their own language, which is more plausible

[@thisisjudith]

At the end, depending on if the trip to earth was actually long, you could tell that ozo means yes or no

[@legendaxicad._]

I am the math teacher. Ozo = x^2 x pi. No solution. But.... if I told you there was, what would it be, yes or no? Ozo means yes, while ulu means no. This is solved by asking if Tee's name is Tee, and whatever he responds with is yes. By mentioning his name, he will respond truthfully. He responds Ozo, which is now yes. This identifies Tee, and solves for Ozo. Now, you mention Eff and pick a answer where you know if it is yes or no. This finds Eff and can lead to maybe discoveries and other possibilities. You then find Arr, and ask Tee if you this is the correct overlords' names.
