There is no real question merely a statement asking for more direction and information to be given.
Meaning that, when you ask a question you are really just calling for assistance.
There is doubt, but only of possible answers (possibilities) you already have.
Surprise is a factor of doubt, merely a more remote possibility.
When you ask when, you have a time in mind...
When you ask which, you have something in mind...
When you ask why, you most often have a reason in mind...
When you ask where, you have a location in mind...
You are looking for direction and information, and you know where you may find direction and information.
What you're doing is either requesting such direction or information from yourself or others in the form of a statement.
For example, 'Can you tell me where the bathroom is?' is the same as 'Please, tell me where the bathroom is, if you know.'
Basically what I am saying is, less lies in question than what you would think. You already have the set of possibilities in mind, it's just a matter of getting to the correct possibility.
When you are asking of yourself direction and information, if you don't know, your task is then to find the answer.
When asking another for direction and information, you are merely asking the same of them, to find the answer for you.
Another example (this time about answers), the question 'What happened?' is followed by an answer in the form of a statement, 'Jill fell down.'
If you look at an answer, something the request for direction and information were designed for, you'll find out the way the request actually works.
Basically, you'll see that questions and answers are merely complimenting statements to get from lack of direction and information, towards being directed and informed.
(And, you're wondering why your computer doesn't ask any questions...)
