You were hired as a foreman on a construction of a laboratory on the island. You arrive at the island and among unfinished buildings you see - a giant ventilator the size of a building, an air balloon ready to fly, and a room completely filled with a floor mops. After some head scratching you remove all this junk and complete the laboratory. But right after the scientists start their work you hear an alert - "ALARM, TOXIC GAS LEAK DETECTED!". - What is going on?! - you are crying, and call the previous foreman. - Hi Alex, we have a toxic gas leak in the lab, what can we do now? - Hmm, I dunno, did you change anything in the project? - Well, I've thrown away floor mops... - They were holding the ceiling. - I'M SORRY WHAT? HOLDING WHAT AGAIN?! - There are gas tanks on the floor above, very heavy, so I had to to fill the room below with mops to hold them. - You could have wrote some note, you know. What should I do now? - Turn on ventilator, it will blow the gas away from the island. - I've removed it a long time ago. - Why? - Why did you built 100 ton ventilator in the first place? You could have just prepare a box of gas masks. - I would have need to search for gas masks and ventilator was a leftover from my previous project, so I've used it. - Alex, we are suffocating here and there is no ventilator! We need help! - The fuck are you doing there then? Get on the air balloon and fly away.
