Brain teasers---puzzles based around imaginary solutions requiring complex mathematical logic to solve---can be addictive. They have the power to grab hold of us and not let go until we've figured out the solution. While every brain teaser requires its own particular application of logic, there are a few problem-solving tips that can be applied to solving just about all of them.
Read the puzzle's scenario carefully. Reading too quickly may cause you to make assumptions or miss details. Also, careful reading, including rereading, may help you to spot clues for coming up with a solution, or at least to think of different approaches to solving the problem.
Write a list of requirements. Start with the objective (the basic problem the scenario requires you to resolve), then list the requirements and obstacles for this solution in clear, concise language using a list format. This will make puzzle-solving easier because it's simpler to compare your solutions to the requirements in this ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
