Not if you need to use mixed content. If you don't, I'd do something like:

    <!ELEMENT QuizPage   (OtherText?, (Question, OtherText?)+)>

and store the #PCDATA in the OtherText element. If it isn't necessary that the
constraint be enforced by the DTD or you do need to use mixed content, you
might consider doing a pass with Schematron - it would make light work of that
kind of checking. The element declaration could then be:

    <!ELEMENT QuizPage   (#PCDATA | Question)*>
