Answer:
Ideology ,Propaganda and Biased
Explanation:
While history is often thought of as the telling of events and facts about the past, it is also a process of interpretation. In some cases, information might be incomplete, or contradictory, and the historian has to decide which sources to consider and which ones to dismiss.
Ideally, the decision should be based on factors that support the informants reliability, but occasionally, the decision is based on the ideology of the historian. This leaves us with a biased and inaccurate view of history, and it is a practice that should be avoided as much as possible by professionals.
