Question: In times past, until the 15th century, in Korea, Literary Chinese was the dominant form of written communication, prior to the creation of hangul, the Korean alphabet. Much of the vocabulary, especially in the realms of science and sociology, comes directly from Chinese, comparable to Latin or Greek root words in European languages. However, due to the lack of tones in Korean,[citation needed] as the words were imported from Chinese, many dissimilar characters took on identical sounds, and subsequently identical spelling in hangul.[citation needed] Chinese characters are sometimes used to this day for either clarification in a practical manner, or to give a distinguished appearance, as knowledge of Chinese characters is considered a high class attribute and an indispensable part of a classical education.[citation needed] It is also observed that the preference for Chinese characters is treated as being conservative and Confucian.

Answer: What was the dominant form of written communication?


Question: The roots of Presbyterianism lie in the European Reformation of the 16th century; the example of John Calvin's Geneva being particularly influential. Most Reformed churches which trace their history back to Scotland are either presbyterian or congregationalist in government. In the twentieth century, some Presbyterians played an important role in the ecumenical movement, including the World Council of Churches. Many Presbyterian denominations have found ways of working together with other Reformed denominations and Christians of other traditions, especially in the World Communion of Reformed Churches. Some Presbyterian churches have entered into unions with other churches, such as Congregationalists, Lutherans, Anglicans, and Methodists. Presbyterians in the United States came largely from Scotch-Irish immigrants communities, and also from New England Yankee communities that had originally been Congregational but changed because of an agreed-upon "Plan of Union of 1801" for frontier areas.

Answer: Where do most presbyterian churches trace their history back to?
