Is there any way to easily find out which of my answers were considered helpful and unhelpful?

There is no way to see in your profile which answers have been voted as helpful as opposed to ones with no votes. You can, however, find unhelpful answers. From your profile/activity page, there are some tabs - questions, answers, tips, etc.Click on answers.

On the left side, some links will pop up - helpful answers, unhelpful answers, and some other ones. Click on unhelpful answers and anything that has been voted as unhelpful by anybody can be seen. Unfortunately, those tabs seem to be broken at the moment, at least on my account.

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.
