Consider the examples below:
- What was the answer to question 4?
- What was the answer to the question 4?
I'm sure that the definite article in the sentence 1 is used correctly. My question is that can we use the definite article before the word question? Or if we can't, why? Because the question 4 is definite. I don't understand why the definite article isn't used in the sentence 1.
