The best response is:
Geography influenced the language, politics, and power centers of both the Eastern and Western Church.
This response acknowledges how geographic factors contributed to the development of distinct religious practices, political structures, and power dynamics between the Roman Catholic Church in Western Europe and the Eastern Orthodox Church in Eastern Europe and the Near East. The differences in language (Latin vs. Greek) and the centers of authority (Rome vs. Constantinople and other cities) illustrate how geography played a crucial role in shaping the identities and interactions of these two branches of Christianity, ultimately contributing to the East-West Schism.
