Until the sixteenth century, human inquiry was primarily based on introspection. The way to know things was to turn inward and use logic to seek the truth. This paradigm had endured for a millennium and was a well-established conceptual framework for understanding the world. The seeker of knowledge was an integral part of the inquiry process. However, today this is no longer the truth. Today, human inquiry needs to know how to research the researchable question. As a result please answer the following questions using APA format and a reference list:
1. Is it necessary for a research question to be put into a research hypothesis to be researchable or testable?
2. What is needed to take a defined problem to a research question?
3. What makes a hypothesis testable?
