You've found the hidden switches, evaded the secret traps, and now your expedition finally stands at the heart of the ancient temple inside The Lost City. But as you study the inscriptions in the near total darkness, two of the eight graduate students accompanying you bump into the alter. Suddenly, two whisps of green smoke burst forth and the walls begin to shake. Fleeing for your lives, you come to a room you passed before with five hallways, including the one to the altar and the one leading back outside. The giant sandglass in the center is now flowing, with less than an hour before it empties, and the rumbling tells you that you don't want to be around when that happens. From what you recall of your way here, it would take about 20 minutes to reach the exit at a fast pace. You know this is the last junction before the exit, but your trail markings have been erased, and no one remembers the way. If nine of you split up, there should be just enough time for each group to explore one of the four halls ahead and report back to this room, with everyone then making a run down the correct path. There's just one problem; the inscriptions told of the altar's curse: the spirits of the city's King and Queen possessing intruders and leading them to their doom through deception. Remembering the green smoke, you realize two of the students have been cursed. At any time, one or both of them might lie, though they also might tell the truth. You know for sure that the curse didn't get you, but you don't know which students can't be trusted, and because the possessed students may lie only occasionally, there is no guaranteed way to test them to determine which are cursed. Can you figure out a way to ensure that you all escape? Don't worry about the possessed students attacking or otherwise harming the others. This curse only affects their communication. Pause the video now if you want to figure it out by yourself! Answer in: 3 Answer in: 2 Answer in: 1 The first thing to realize is that since you know you aren't possessed, you can explore one of the halls alone. This leaves eight students for the remaining three paths. Sending groups of four down just two of the paths won't work because if one group came back split two versus two, you'd have to guess who to trust. But splitting them into one pair and two trios would work every time, and here's why. The possessed students might lie, or they might not, but you know there are only two of them, while the other six will always tell the truth. When each group returns to the hall, all of its members will either give the same report or argue about whether they found the exit. If a trio returns in total agreement, then you know none of them are lying. With the pair, you can't be sure either way, but all you need is reliable evidence about three of the four paths. The fourth you can figure out using the process of elimination. Of course, none of this matters if you're lucky enough to find the exit yourself, but otherwise, putting everything together leaves you with three possibilities. If each group gives a consistent answer, either everyone is telling the truth, or the two possessed students are paired together. In either case, ignore the duo. If there's only one group arguing, both others must be telling the truth, and if there are two conflicts, then the possessed students are in separate groups and you can safely trust the majority in both trios since at least two people in each will be truthful. The temple collapses behind you as greenish vapors escape from two of the students. You're all safe and free from the curse. After that ordeal, you tell your group they all deserve a vacation, and you just happen to have another expedition coming up.
Pronašli ste skrivene prekidače, izbegli skrivene zamke, i sada je vaša ekspedicija konačno stigla do samog srca drevnog hrama unutar Izgubljenog Grada. No, dok proučavate zapise u skoro potpunom mraku, dvoje od osam studenata iz vaše grupe udare u oltar. Odjednom, dva pramena zelenog dima izbiju napolje i zidovi počinju da se tresu. Dok bežite da se spasete, nailazite na sobu koju ste ranije prošli koja vodi u pet različitih hodnika, uključujući i onaj ka oltaru i onaj koji vodi napolje. Ogromni peščanik u sredini sada teče, i ostaje manje od jednog sata pre nego što se isprazni, a tutnjava vam govori da ne želite da budete tu kada se to desi. Koliko se sećate od puta dovde, trebalo bi vam oko 20 minuta da brzim korakom dođete do izlaza. Znate da je ovo zadnje skretanje pre izlaza, no, vaši tragovi su izbrisani, i niko se ne seća puta. Ako se vas devetoro razdvoji, trebalo bi da bude dovoljno vremena da svaka grupa istraži jedan od četiri hodnika pred vama i podnese izveštaj u ovoj sobi, pa da svi onda pobegnu pravim putem. Postoji samo jedan problem; zapis govori o kletvi oltara: duhovi Kralja i Kraljice ovog grada zaposedaju uljeze, i vode ih ka propasti kroz obmanu. Kada se prisetite zelenog dima, shvatate da je dvoje studenata pod kletvom. U bilo kom trenutku, jedno ili oboje mogu da slažu, mada bi isto tako mogli da kažu istinu. Zasigurno znate da vi niste pod kletvom, no, ne znate kojim studentima ne možete verovati, i budući da zaposednuti studenti možda slažu samo povremeno, ne postoji siguran način da saznate ko je pod kletvom. Možete li naći način na koji ćete svi pobeći? Ne brinite o tome da zaposednuti studenti napadnu ili na bilo koji drugi način povrede ostale. Kletva utiče samo na njihovu komunikaciju. Sada pauzirajte video ako želite da rešite zagonetku sami! Odgovor za: 3 Odgovor za: 2 Odgovor za: 1 Prvo što treba da shvatite je da, budući da znate da vi niste zaposednuti, možete da pretražite jedan od hodnika sami. Tako nam ostaje osam studenata za preostala tri puta. Ako pošaljete grupe od četvoro kroz samo dva puta neće uspeti, jer ako jedna grupa ima podeljena mišljenja dvoje protiv dvoje, morate da pogađate kome da verujete. No, ako ih podelite na jedan par i dve grupe po troje, to mora uspeti svaki put, a evo i zašto. Zaposednuti studenti će možda lagati, a možda i neće, ali znate da je njih samo dvoje, dok će ostalih šest uvek da kaže istinu. Kada se svaka od grupa vrati u dvoranu, svi njeni članovi će ili dati isti iskaz ili se svađati oko toga da li su našli izlaz. Ako se grupa od troje potpuno slaže, onda znate da niko od njih ne laže. Sa parom, svakako ne možete biti sigurni, no, sve što vam treba je pouzdan iskaz o tri od četiri puta. Četvrti možete odgonetnuti procesom eliminacije. Naravno, ništa od ovoga nije važno ako imate sreće da sami nađete izlaz, no, u protivnom, kada sve saberete ostaju vam tri izbora. Ako se iskazi svih članova grupa međusobno slažu, ili svi govore istinu, ili su dva zaposednuta studenta sparena. U svakom slučaju, ignorišite par. Ako se samo jedna grupa prepire, druge dve grupe govore istinu, a ako postoje dve konfliktne grupe, onda su zaposednuti studenti u suprotnim grupama, stoga možete da verujete većini u obe grupe od po troje budući da najmanje dvoje u svakoj od tih grupa govori istinu. Hram se ruši iza vas dok zeleni prameni dima napuštaju dva studenta. Svi ste sigurni i slobodni od kletve. Posle teškog iskušenja, govorite grupi da svi zaslužujete odmor, i da vam igrom slučaja, sledi još jedna ekspedicija.
