How can asking research questions help you support a reason?

A good research question is open and exploratory. It is manageable within the scope of the topic, degree, time, assessment and student. The question is free of ambiguity. It is clear, simple and interesting to others. The question relates to the subject matter... pre-reading and a review of the literature is required to formulate a good research question.

All of these give you a clear space and base to support a reason.
