Durable goods, non durable goods, services?

Both, but a train can be a consumers good as well. It depends on how it is used. If used for a lovely train ride or as a means of transportation by a consumer t is a consumers good, if used to transport materials, store materials, or help to produce a product then it is a producers good.

Either way, it is certainly a durable good (I.E. not immediately used up in production the way X amount of butter would be in the making of a cake).

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.
