You have to click the suggest link and then high light what word or phrase you wish for system to find links to. It has changed in the last couple of weeks . I had the same problem.
I think you can highlight up to 5-6 words but I may be wrong on that. Try it that way and I am sure it will work for you. Hope this helps.
This tool has been discontinued. Now you have to find your own links.
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.
