In at least one hundred words, explain how the ending of Achebe's Things Fall Apart is an example of dramatic irony. Use evidence from the text to support your answer.

As a story about a culture on the verge of change, Things Fall Apart deals with how the prospect and reality of change affect various characters. The tension about whether change should be privileged over tradition often involves questions of personal status. Okonkwo, for example, resists the new political and religious orders because he feels that they are not manly and that he himself will not be manly if he consents to join or even tolerate them. To some extent, Okonkwo's resistance of cultural change is also due to his fear of losing societal status. His sense of self-worth is dependent upon the traditional standards by which society judges him. This system of evaluating the self inspires many of the clan's outcasts to embrace Christianity. Long scorned, these outcasts find in the Christian value system a refuge from the Igbo cultural values that place them below everyone else. In their new community, these converts enjoy a more elevated life and status.
