Final answer:
Estonia, as a predominantly atheist country, reflects its high degree of secular values, indicating a separation of state and religious institutions.
Step-by-step explanation:
Estonia is described as a predominantly atheist country, which reflects the country's high degree of secular values. The term secular refers to attitudes, activities, or other things that have no religious or spiritual basis. In the context of a society or a country, secular values suggest a public space or policies that are not influenced by religious beliefs, which can lead to a lower prevalence of religious practices among the population. This is indicative of a broader societal preference for separating the institution of the state from religious institutions and minimizing the role of religion in the public and governmental spheres.
