Which offered strong evidence of the existance of the xia dynasty?
1. verbal histories expressing myths
2. uncovering artifacts of an advanced society
3. evidence of a warring society
4. pictographic records

The correct answer is 2. Uncovering artifacts of an advanced society offered strong evidence of the existance of the Xia Dynasty.

Explanation:

The Xia Dynasty ruled China between  2100 and 1600 BC. No writings have survived from this period, but information about the dynasty was written more than a thousand years later. Thus, the details and exact years are uncertain, even doubts have been raised about the existence of the dynasty, although archaeological evidence speaks for it.  

Archaeological finds include the Xia Dynasty Palace, built in 1700 BC. The remains of the palace area, located in Erlitou in central China, extend to an area of more than two thousand square meters. From the relatively well-preserved palace, it can be concluded that it has served as a model for the larger palaces of later dynasties. Bronze artefacts were also found in the ruins of the Bronze Age palace.
