For example, if the title of the piece of writing is "Can We Know The Universe?" and I want to embed this into a question, where would the question mark belonging to my sentence go? I assume it would be placed outside the quotation marks, so the sample sentence would be:
What does Carl Sagan assert with his example about table salt in "Can We Know The Universe?"?
The two question marks separated by the quotation marks is awkward, but is it correct in terms of formatting? What would the correct formatting be?
