What is the difference between a factual and an interpretive question?

A factual question is when there is only one answer and it is a fact. But an interpretive question has more than one answer to the question and there should be different perspectives and layers to the question itself. An example of an factual question is How are volcanoes made? and an example of a interpretive is Why are people scared of volcanoes? That question is a factual question because there is only one way of answering how volcanoes are created and there would be lots of facts. Why are people scared of volcanoes? This is a interpretive because from this one simple question we can have different answers from different perspectives.
