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.
Menjalankan latihan amali di makmal di gunung terpencil bukanlah idea yang bijak. Menarik tuil yang ada simbol tengkorak untuk tahu fungsinya juga bukanlah tindakan yang bijak, tapi sekarang bukan masa untuk penyesalan kerana anda perlu pantas melarikan diri dari zombi mutan. Penjaga bangunan, penolong makmal dan profesor tua bersama anda. Anda ada kelebihan, namun hanya ada satu cara untuk selamat: ada jambatan tali usang merentangi gaung besar Anda boleh menyeberanginya dalam satu minit, penolong makmal pula ambil masa dua minit. Penjaga bangunan lambat kerana perlukan lima minit, dan profesor perlukan sepuluh minit, sambil memegang tali sepanjang perjalanan. Mengikut kiraan profesor, zombi akan dapat kejar anda dalam masa 17 minit, jadi masa terhad untuk selamatkan semua orang dan potong tali. Malangnya, jambatan hanya boleh tampung dua orang pada satu masa. Lebih teruk lagi, di sana gelap gelita, dan pelita buruk anda ialah satu-satunya cara menerangi ruang kecil. Bolehkah anda fikirkan cara untuk bantu semua orang larikan diri? Ingat: maksimum dua orang boleh merentasi jambatan bersama, seorang mesti memegang pelita atau berdiri di sebelahnya, dan salah seorang boleh tunggu dalam gelap di tebing gaung. Paling penting, semua orang mesti menyeberang sebelum zombi sampai. Kalau tak, zombi pertama akan pijak jambatan semasa ada orang. Akhirnya, tiada muslihat boleh digunakan. Tak boleh hayun ke seberang, gunakan jambatan sebagai rakit, atau berkawan dengan zombi. Jeda video sekarang jika anda mahu cuba selesaikan sendiri! Jawapan dalam: 3 Jawapan dalam: 2 Jawapan dalam: 1 Mula-mula, sepertinya walau apa tindakan anda, anda kekurangan masa satu ke dua minit, tapi ada caranya. Cara terbaik ialah mengurangkan masa yang dibazir oleh dua orang terlambat dengan menyuruh mereka menyeberang bersama. Oleh sebab perlunya berulang-alik dengan pelita, anda perlukan orang terpantas untuk melakukannya. Jadi, anda dan penolong makmal menyeberang dengan laju sambil memegang pelita, meskipun anda terpaksa perlahan sikit untuk bersamanya. Setelah dua minit, kalian di seberang, sebagai orang yang terpantas, anda patah balik dengan pelita. Baru tiga minit berlalu. Setakat ini, semuanya baik. Sekarang bermula perkara paling sukar. Profesor dan penjaga bangunan ambil pelita dan menyeberang bersama. Masa diambil 10 minit kerana penjaga bangunan perlu perlahan untuk profesor tua yang asyik bersungut yang dia tak patut beri zombi penglihatan malam. Setibanya mereka, hanya berbaki empat minit, dan anda masih berada di hujung jambatan yang salah. Tapi ingat, penolong makmal menunggu di seberang, dan dia orang kedua terpantas antara semua. Jadi dia ambil pelita daripada profesor dan meluru ke arah anda. Hanya tinggal dua minit, kalian menyeberang untuk kali terakhir. Setibanya anda tiba di tebing gaung, anda gunting tali dan jatuhkan jambatan tepat pada waktunya. Musim panas depan, anda patut duduk di perpustakaan sahaja.
