Answer:
read all there was to know about the Reformers
Step-by-step explanation:
The historical method is used by historians to show information about a historical topic from the incubation stage to the hatching stage. i/e from the start to the final stages.
If this historical method is used to study the Reformation, then there would be a need to search all the available information from the early Reformation period, how it started, the people involved, any issues faced and then follow the development of the movement from the start to the final stages.
