Answer: When archaeologists are reconstructing the "Who, where, and when?" of the past, they are reconstructing history(Social changes).
Explanation:
The information generated will tell us about the way of life of past societies and the conclusions obtained provide new data that will help the reconstruction of human history and culture.
The only way we can understand past societies is through what they left behind, their material remains. The interrelation of these materials and the environmental contexts will give us the key to describe and understand an extinct society.
