Question

It is important to make certain that your source for historical research is

Answer 1

Primary sources are first-hand accounts of events or time periods in history

Answer 2

Accurate

Step-by-step explanation:

Although there is not really information that is unbiased because when the source is a person, it is practically impossible to be 100% objective, you still have to be sure about the accuracy of the information. If the information is first handed, you can actually place it in a larger historical context and even analyze how the biased opinion tells you even more about that moment in history. Pictures and documents tend to be much more reliable than a letter of someone who heard something and is gossiping with an aunt.
