Question

The good Missionary disgusted with this idle Tale, said, What I delivered to you were sacred Truths, but what you tell me is mere Fable, Fiction and Falsehood. The Indian offended, reply'd, My Brother, it seems your Friends have not done you Justice in your Education, they have not well instructed you in the Rules of common Civility. You saw that we who understand and practise those Rules, believ'd all your Stories: Why do you refuse to believe ours?

C. By showing the difference in the beliefs and their inability to understand one another. hope this helps :)

Answer 2

Answer: by showing the settlers their inability to see the similarities with Native Americans

Explanation:

The Indian points out that, whereas they´ve made the effort to accept the Missionary´s Stories, the settlers did not attempt to understand the beliefs of the Native Americans. Considering that missionary work is a way to civilize cultures considered uncivilized, the irony resides in the Indian pointing out the missionary´s lack of common Civility.
