Final answer:
The passage suggests a bias in favor of Britain because it details the alliances formed with Native American tribes during historical conflicts and emphasizes their preference for British support to prevent American expansion.
Step-by-step explanation:
The passage indicates a bias in favor of Britain, primarily because it highlights the strategic alliances that the British formed with various Native American tribes during different conflicts, such as the French and Indian War and the American Revolutionary War. It is stated that the Shawnee Confederacy, along with other tribes like the Iroquois and Delaware, aligned themselves with the British through treaties like the Treaty of Easton. The main reason for the support of the British by the Indian tribes and nations was the fear of American expansion and consequent loss of land, which is underlined as true in the reference material provided. It was a common belief that an American victory would lead to greater land confiscation compared to a British one. Furthermore, during the American Revolutionary War, while the Iroquois Confederacy declared neutrality, not all tribes followed this decision, with many siding with the British.
