Taking that internship in a remote mountain lab might not have been the best idea. Pulling that lever with the skull symbol just to see what it did probably wasn't so smart, either, but now is not the time for regrets because you need to get away from these mutant zombies fast. With you are the janitor, the lab assistant, and the old professor. You've gotten a headstart, but there's only one way to safety: across an old rope bridge spanning a massive gorge. You can dash across in a minute, while the lab assistant takes two minutes. The janitor is a bit slower and needs five minutes, and the professor takes a whole ten minutes, holding onto the ropes every step of the way. By the professor's calculations, the zombies will catch up to you in just over 17 minutes, so you only have that much time to get everyone across and cut the ropes. Unfortunately, the bridge can only hold two people at a time. To make matters worse, it's so dark out that you can barely see, and the old lantern you grabbed on your way only illuminates a tiny area. Can you figure out a way to have everyone escape in time? Remember: no more than two people can cross the bridge together, anyone crossing must either hold the lantern or stay right next to it, and any of you can safely wait in the dark on either side of the gorge. Most importantly, everyone must be safely across before the zombies arrive. Otherwise, the first zombie could step on the bridge while people are still on it. Finally, there are no tricks to use here. You can't swing across, use the bridge as a raft, or befriend the zombies. Pause the video now if you want to figure it out for yourself! Answer in: 3 Answer in: 2 Answer in: 1 At first it might seem like no matter what you do, you're just a minute or two short of time, but there is a way. The key is to minimize the time wasted by the two slowest people by having them cross together. And because you'll need to make a couple of return trips with the lantern, you'll want to have the fastest people available to do so. So, you and the lab assistant quickly run across with the lantern, though you have to slow down a bit to match her pace. After two minutes, both of you are across, and you, as the quickest, run back with the lantern. Only three minutes have passed. So far, so good. Now comes the hard part. The professor and the janitor take the lantern and cross together. This takes them ten minutes since the janitor has to slow down for the old professor who keeps muttering that he probably shouldn't have given the zombies night vision. By the time they're across, there are only four minutes left, and you're still stuck on the wrong side of the bridge. But remember, the lab assistant has been waiting on the other side, and she's the second fastest of the group. So she grabs the lantern from the professor and runs back across to you. Now with only two minutes left, the two of you make the final crossing. As you step on the far side of the gorge, you cut the ropes and collapse the bridge behind you, just in the nick of time. Maybe next summer, you'll just stick to the library.
在深山裡的實驗室中實習, 可能不是一個好主意。 拉下畫有骷髏符號的控制桿, 看看會發生什麼事, 或許也不是個聰明的想法。 但現在,已經沒時間後悔了, 因為你得趕緊逃離 這些突變的殭屍。 與你同行的,有管理員、 實驗室助理和一位老教授, 雖然你們已經領先一步, 但要安全逃離,還需要: 跨越大峽谷上的一座老舊吊橋。 你衝過吊橋只需要 1 分鐘, 然而實驗室助理需要 2 分鐘。 管理員稍慢一些,需要 5 分鐘, 而教授需要整整 10 分鐘, 因為他走每一步 都要緊握著繩索來前進。 根據教授的計算, 在 17 分鐘後, 殭屍就會追上你們, 你只有這麼多的時間, 讓所有人通過吊橋並剪掉繩索。 不幸的是,吊橋同一時間 只能承載兩個人。 更糟糕的是, 天色太暗, 讓你伸手不見五指, 而你手中的老舊油燈, 只能照亮一個小範圍。 你能想出讓每個人 及時逃脫的方法嗎? 記住:不能超過兩人 同時走在吊橋上; 跨越吊橋時,若不帶著油燈, 就得走在提燈者旁。 而所有人都可以安全地待在 漆黑的峽谷兩端。 最重要的是,所有人必須在 殭屍抵達前安全地通過吊橋。 否則,當殭屍一踏上橋時, 橋上的人會使吊橋負荷過重而斷裂。 最後,不能用任何花招。 你不能用繩索擺盪過去, 也不能把橋做成木筏, 或者和殭屍當朋友。 如果你想要自己找出答案, 請按下暫停鈕。 還有 3 秒、 2 秒、 1 秒、 一開始,你可能會認為 無論怎麼試, 始終會差個一、兩分鐘, 但確實是有辦法的。 關鍵就在於: 讓最慢的兩人走在一起, 來減少他們所需要花的時間。 而且,要有人提著油燈走回來 這總共需要兩趟, 你需要讓跑得最快的人 來做這件事, 所以,你先和實驗室助理 提著油燈快速通過, 然而你必須放慢一些 來配合他的速度。 兩分鐘後, 你們兩人都通過吊橋, 然後跑得最快的你, 再迅速提著油燈返回, 這樣只花了三分鐘。 到目前為止都相當順利。 最難的部分來了。 教授和管理員 提著油燈一起過橋, 這花了他們 10 分鐘, 因為管理員必須 為了老教授放慢腳步, 教授喃喃自語抱怨著: 他當初不該讓殭屍擁有夜視能力。 當他們跨越吊橋時, 只剩下 4 分鐘, 而你仍困在對岸。 但是記住,實驗室助理 已經在另一邊待命, 而她是隊伍中跑第二快的人。 所以她從教授手中拿起油燈, 快速跑回去你那邊。 現在只剩下 2 分鐘, 你們兩位最後一次過橋, 當你踏上峽谷的另一側, 你剪斷繩索, 摧毀身後的吊橋, 時間剛好趕上。 或許,明年夏天 你只會想泡在圖書館內。
