One wrinkle to this question is that "cause" can have many layers, many parts, and many entry points.  
E.g. if someone shoves at me and I fly into a rage, what is the "cause"?  
Is it because I got shoved?  I would say no, that was just a trigger.  
Is it because I had missed breakfast and was in a low blood sugar state?  I would say not really the "cause", just an intermediate step.
Is it because of frustrations in my childhood, due to which I have low self-esteem and am easily triggered by what I perceive as disrespect?  That's closer to a deeper "cause", but might or might not be relevant to cause of my distress in the *current* situation.  
Any situation can be addressed via multiple "levels", using various starting points as a credible "cause".

Yes, what was the cause?
Only if you know it, you can remove it.
