Final answer:
Using primary and secondary sources alone is not enough to provide complete information about an archaeological site or artifact. Other methods like carbon dating, aerial surveys, and ground-penetrating radar can help uncover more information. Oral history can be helpful but should be cross-referenced with other sources for accuracy.
Step-by-step explanation:
Using primary and secondary sources is important but not enough to give complete information about an archaeological site or artifact. Other methods can be used to uncover more information, such as carbon dating which can provide insights into the age of the artifacts. Aerial surveys and ground-penetrating radar can also yield more data by revealing hidden structures and features at the site.
While oral history can be helpful in understanding the context and personal experiences related to an archaeological find, it should be treated with caution as it can be subjective and prone to inaccuracies or biases. It is important to cross-reference oral history with other sources and evidence to ensure accuracy.
