There was a man in the desert who died with his head down. There were several luggage boxes scattered around him. He was holding half a match tightly in his hand and reasoning about how this man died.

Five explorers traveled around the world in a hot air balloon. As a result, when they flew to a big desert, the power was suddenly insufficient and the concentration of hot air balloons dropped! This is a decision made by several people: you must throw heavy objects below, or you will all die in the desert! So they threw the suitcase out, but the hot air balloon was still falling-another person was going to be thrown out! Of course, no one wants to be thrown out, because that means death. So they decided to draw lots quickly. A man took out five matches and broke one of them. If someone gets a half game, he must fall down. It's a pity that this half match was drawn by himself-so he was mercilessly thrown out, bowed his head and died in the desert. The man is looking for another half match with gunpowder, which is the only kindling. This half match fell into a small but deep bunker with the man's head down. When looking for it, the sand fell and buried his upper body. \n The temperature difference between day and night in the desert is quite large. It's hot during the day, but it's cold at night. Holding a match with your head in your hand should be used in the fire test at night. The last one froze to death and was thirsty. Several people were on the hot air balloon, and suddenly something went wrong, asking for load reduction. They used the method of smoking matches. The man drew the shortest match, so he fell down. In the desert, it was very cold at night, and he froze to death. Several people came to this desert by hot air balloon, but they encountered a hot air balloon failure, so they had to lose weight, throw everything down, and finally draw lots. Whoever draws the shortest match will jump.
