Think, Rationalize and Then Discover

Why is it that as humans we are so inclined to ask questions?
Is it because of our thirst for knowledge and power?
Is it because these questions branch off each other?
Or is it the reason far deeper than we could ever imagine?

We ask questions because there is a plethora of information in the world waiting to be sought out.
This information is not always obvious or to our liking but once we find the answer, we might be eager to dig deeper.  
So how then do we determine what to ask?
Do certain questions take precedence over each other?
Or is there no bad question to ask?
When asking a question there are three key factors we must take into account: thinking, rationalizing and discovery.  

While thinking and rationalizing can be considered very similar in the broad scope of things, there are a few minor differences that distinguish them.
For starters when we rationalize something we are justifying that it is valid or has a logical premise.
When we are thinking we are not always rationalizing right away, rationalizing comes after a question has been asked.
It is only after we have rationalized our own question that we can move on to discovering the answer.
