I am writing a paper in which, in my answer to the third question, I have written a sentence which includes the clause:
", as referred to in my answer to question 2".
Should the word "question" be capitalised in the above sentence? It feels as though "Question 2" is sort-of a proper noun in this context.
Of course, if I were setting the paper and listing the questions, I would always capitalise "Question 1", "Question 2", etc. However, this would be partly because these would begin a partial sentence and so be capitalised on that basis. This seems a subtly different situation.
