The correct answer is A. Contextualization differentiates the modern era from other historical periods.
Explanation:
The circumstances and incidents surrounding an event are called historical context. This context is formed by everything that, in some way, influences the fact when it happens.
A fact is always tied to its time. Therefore, when analyzing events that took place tens, hundreds or thousands of years ago, it is essential to know the historical context to understand them. Otherwise, we would be analyzing and judging what happened in a totally different era with a current look.
