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.
你找到了祕密的開關 躲過了隱藏的陷阱 現在你的探險隊總算站在 「失落之城」裡古神殿的中心 但當你身處幾乎完全黑暗中 解讀銘文時 同行八位研究生中的兩位 碰撞到了祭壇 突然,兩縷綠色煙霧冒了出來 牆壁開始震動 趕快逃命 你們來到之前經過 有著五條通道的密室 其中一條通往祭壇,一條則可回到外面 中央有個巨大的沙漏正在滴漏 不到一個小時便會漏盡 隆隆聲響告訴你 在那之前得離開這現場 你回憶一下來時之路 最快要花二十分鐘才能抵達出口 你知道這是出口前的最後一個岔路 但來時的足跡都已被抹掉了 而且沒有人記得正確的路 如果你們九個分組 應當有足夠時間 讓每一組各自探索四條通道之一, 然後返回彙報 接著所有人一起從正確的路逃出去 這裡正好有一個問題 銘文記載了祭壇的詛咒: 國王和皇后的幽靈 將纏附在侵入者身上 並透過詭計將他們帶向死亡 你想起了綠色的煙霧 意識到兩個學生已遭到詛咒 他們其中一或兩人隨時可能說謊 也可能說實話 你確信自己並沒遭到詛咒 但你不知道哪兩個位學生是無法信任 因為被附身的學生可能只會偶爾說謊 因此並不能保證能夠測試出誰被詛咒了 你能想出方法讓你們全都脫困嗎? 不必擔心遭附身的學生攻擊 或者傷害別人 這詛咒僅會影響他們的溝通而已 現在請暫停影片, 如果你想自己找出方法的話 公佈答案:3 公佈答案:2 公佈答案:1 首先要了解的是 既然你知道你沒有被附身 你可以自己探索其中一條通道 剩下的三條交給八位學生 各派出 4人組 (4-4) 去探索兩條通道是行不通的 因為如果一組回來後 分成 2 對 2 各說各話 你必須去猜測要相信誰 但分成一個兩人組、兩個三人組 ( 2-3-3 ) 每次都可行 接著說明理由 被附身的學生可能說謊,也可能不會 但你知道這僅是其中的兩位 而另外六位一直都說實話 當各組都回到大廳時 隊員不是回報相同的內容 就是在爭論他們是否找到出口 如果三人組帶回一致的內容 便知道他們都沒有說謊 至於兩人組,無論意見一致否, 都無法確認 但你需要只是四條中的三條 有可靠的証據 第四條用「刪去法」就可找到答案 當然,這些都是紙上談兵── 只要你夠幸運自己找到出口 否則彙整所有資訊後, 就只有三種可能性 一:如果各組的回應都一致 則可能是每個人都說實話 或是被附身的兩位學生在同組 無論哪一種,忽略兩人組 二:如果只有一組在爭執, 則其餘兩組都說了實話 三:如果有兩組在爭執,可知 被附身的學生 是各分在不同的兩組裡 你可安心地採信 三人組中多數人的答案 因為各組至少有兩個人是可信的 神殿在你們身後崩塌 綠色煙霧從兩位學生身上竄出 你們全都安全了,也擺脫了詛咒 經歷了這次的考驗 你告訴你的團隊, 他們都應該好好放個假 而你也剛好想到了另一個探險之旅
