A British newspaper once held a prize-winning campaign titled: Three people were carried on a hot air balloon. One is an environmental expert who can save people from the bad luck of environmental pollution; the other is a nuclear expert who has the ability to prevent a global nuclear war; the third is a food expert who can save tens of millions of people from famine. At this moment the hot air balloon is about to crash. One person must be dropped to reduce the load. Who should be left? The answer letter flew like snowflakes, and as a result, the winner of the huge bonus was a little boy. His answer was: go fattest. The correct interpretation of this text is:. ['This is an example of more solutions than problems.', 'This is an example of simplification of complex problems.', 'This is the option to get things done quickly.', 'This is the story of a small puck solving a big problem.']
