Why does it seem like nobody ever chooses an answer as "best answer" even if its the only answer. do you lose money?

If the asker doesn't choose a best answer the community votes on the answer. If the asker doesn't choose and the community votes they still have to pay the tip. "The asker has four days from the time the question is asked to select a best answer by clicking the Select as Best Answer button next to the answer they choose.

If the asker doesn't select a best answer within four days, the question moves to the undecided questions tab and the community votes for the best answer. At the end of the voting period, which lasts two days, the answer with the most votes is declared the best answer and receives the tip if a tip was offered. If no best answer has the most votes, the question is closed without a best answer and if a tip was offered the the tip is credited to the asker's account.

If there's a tie, the voting period is extended until one answer has the most votes.

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.
