Answer:
Using different research sources.
Step-by-step explanation:
The use of multiple sources of research will prevent you from being stuck in a single story in the history of Ghana. That's because, each research source will show you different approaches to this subject, diversified information and a variety of events that took place during the development of the history of Ghana. In this way, your work will be richer, more fluid and complete, without getting stuck in a single event, but presenting a comprehensive work.
