Is "What factors contributed to the sinking of the Titanic?" a good EPQ title??

I do wonder about this topic in general how many original sources of information are going to be available to you to research ?

I've seen lots of people post their EPQ titles and they all seem to be quite vague where they can write about lots of aspects, I was wondering if mine is too specific and worrying that I wouldn't have enough to write.

The titanic is something that I am interested in and coincided to have a background knowledge on but i am worried the title isn't suitable.

I'm doing an EPQ and what they made really apparent to me at my school was the need to thoroughly research your question, as well as develop it and refine it in the research stage, before you begin to write. If you feel that there enough sources for you to be selective, and that you would be able to write a comprehensive answer then I don't see why not. Perhaps speak to your supervisor about it? They should be able to tell you if you would realistically be able to meet the various marking criteria or not.
