eyewitnesses often have different accounts of events, so historians must\nbelieve every account they see or…

Brief Explanations:

Eyewitness accounts can vary due to factors like perception, memory, or bias. Historians, as researchers of the past, cannot take accounts at face - value. Believing every account (first option) is naive as there may be inaccuracies. Considering no accounts (third option) ignores a potential source of historical information. Determining only one account as truth (fourth option) is too simplistic as multiple accounts might hold partial truths. Evaluating each account (second option) allows historians to cross - reference, analyze biases, and get closer to historical truth.

Answer:

evaluate each account to discover the truth.
