Explanation:
When a historian cannot explain all the facts because there are not enough resources, in this case, he/she must see what was already found, wrote, researched about the event and think about the gaps. What could have happened there? Here, the imagination is important, because the historian will think about the probable events that occurred there, based on the sources he/she has.
