Step-by-step explanation:
The correct answer is Option D: What was the population density of the region?
Studying artifacts can provide valuable insights into many aspects of the past. However, population density is a question that cannot be answered solely by studying artifacts. Population density refers to the number of people living in a given area. While artifacts can provide information about the material culture and lifestyle of a culture, they do not directly reveal the population density.
To determine population density, historians and social scientists rely on other types of evidence, such as historical records, census data, and archaeological surveys that examine the settlement patterns and distribution of human remains.
Moreover, population density is influenced by various factors, including the availability of resources, climate, and social organization. Therefore, it requires a multidisciplinary approach that combines archaeological, historical, and geographical research to provide a comprehensive understanding of the past.
