Can Search Engine bot index a content which is served based on cookie?

They see the content that a user without the cookie will see as the bots do not save cookies.

Some bots can run javascript and accept cookies. Some recent articles suggest that Google is using real browsers for crawling (hence the page-screenshots in the instant feature, which text-based bots cannot create).

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.
