In my memory there was still a wonderful task: aquariums of different capacities, something like 8, 5 and 2 liters, you need to pick up 4 liters of water. The Olympic response is to tilt the 8-liter and pour half the water, orienting along the edges. One in 50 people thinks so.
NoNoNo
One of the fifty. While you will pour half of the 8-liter, I will take it twice with the 2-liter and salt in the 5-liter. It will take 10 seconds and no chance to break the 8th. With such tasks and decisions, it is not surprising that the Motherland is in one place. Colibries are untouched.
