Can I start a sentence with "because" if it comes after a question mark?
Why did I drink? Because I was thirsty.
Why did I drink? because I was thirsty.
I know this style of question has been asked before, however I've been told you should never start a sentence with "because". Yet, if a question mark ends a sentence then how can I continue without capitalizing the "b" in because? In this case, should I have to avoid "because" all together and instead write
Why did I drink? I was thirsty.
