Final answer:
The best conclusion drawn from the facts is that Europeans and Native Americans had potential for diplomatic relations, as evident in the collaborative actions of James Oglethorpe and Chief Tomochichi.
Step-by-step explanation:
Based on the facts provided about the relationship between James Oglethorpe, Chief Tomochichi, and their joint endeavors, the BEST conclusion that can be drawn is that Europeans and Native Americans could get along through diplomatic connections.
This conclusion is supported by the evidence of the joint journey to England, the efforts of Chief Tomochichi to ensure that other Georgian tribes saw Europeans as fair, and the cooperative expedition to determine Georgia's southern border.
This collaborative approach was evident even amid broader tensions and conflicts between European settlers, Indigenous peoples, and between European powers themselves for control over land and resources.
The evidence suggests that James Oglethorpe and Chief Tomochichi formed a diplomatic relationship, embarking on a journey together and going on an expedition to determine Georgia's border. Chief Tomochichi also ensured other Georgian tribes that the Europeans were fair people. This shows an effort to establish peaceful relations and work together.
It is important to note that this conclusion is based on the given facts and may not represent the entire history of European-Native American relations.
