How is organizing the past by region similar to or different from organizing the past by period?

a. A historian who organizes the past by region focuses on a specific start and end date, whereas a historian who organizes the past by period focuses on the most influential individuals.

b. A historian who organizes the past by region focuses on a big idea that occurs across history, whereas a historian who organizes the past by period focuses on a specific area of the world.

"a. A historian who organizes the past by region focuses on a specific start and end date, whereas a historian who organizes the past by period focuses on the most influential individuals" would be the best option from the list, but in reality historians who focus on a specific period take into account many different factors of life during that period.

Correct answer choice is:

a. A historian who organizes the past by region focuses on a specific start and end date, whereas a historian who organizes the past by period focuses on the most influential individuals.

Explanation:

This whole process is thus a method or study of classifying the past into separate, quantified named blocks of your time so as to encourage the study and evaluation of history. This ends up in an illustrative hypothesis that offers appropriate terms for periods of your time with comparatively substantial attributes. However, deciding the precise starting and ending of any "period" is commonly impulsive. It's modified over time in history.

To the extent that history is continuous and inapplicable, all systems of periodization are additional or less impulsive. However without named periods, but clumsy or inaccurate, the diversion would be nothing but dispersed events without a structure to assist people to perceive them.
