Answer:
Primary sources generally include bias.
Explanation:
History is one of the most important sciences that human beings have, we as a species need to remember what has happend in the past, in order to not make the same mistakes and create a better future for our societies, but to be objective while reporting history is difficult because we all are biased, and primary sources are biased as well, for example, those who recorded the civil war were the winners, so they have an opinion of what happened, we will never get to know the version of the loosers, or the version of the Native Americans killed in the conquest, so primary sources are biased thus we can only know as much as their point of view allows us to know.
