What is the most obvious sign of bias in a historical text?

Lack of accuracy on Facts.

Explanation:

Taking into consideration the question about obviousness and the type of text, the lack of accuracy is one of the most significant bias one can see in any historical text.

When we talk about history, it requires a vast ammount of details including dates, places and even some info about possible occurred events. But when a text does not completely give this information with exact accuracy it leads the reader to have more questions to be answered rather than a full text comprehension.

a causal relation between two events exists if the occurrence of the first causes the other. the first event is called the cause and the second event is called the effect. a correlation between two variables does not imply causation.
