Input: Read this: Poetry is a form of literary art which uses aesthetic and rhythmic qualities of language to evoke meanings in addition to, or in place of, prosaic ostensible meaning. Poetry has traditionally been distinguished from prose by its being set in verse;[a] prose is cast in sentences, poetry in lines; the syntax of prose is dictated by meaning, whereas that of poetry is held across metre or the visual aspects of the poem. Prior to the nineteenth century, poetry was commonly understood to be something set in metrical lines; accordingly, in 1658 a definition of poetry is "any kind of subject consisting of Rythm or Verses". Possibly as a result of Aristotle's influence (his Poetics), "poetry" before the nineteenth century was usually less a technical designation for verse than a normative category of fictive or rhetorical art. As a form it may pre-date literacy, with the earliest works being composed within and sustained by an oral tradition; hence it constitutes the earliest example of literature.
Question: Until when was prose considered to need metrical lines?

Output: unanswerable

Input: Read this: Oklahoma i/oklhom/ (Cherokee: Asgaya gigageyi / ; or translated (oalahoma), Pawnee: Uukuhuuwa, Cayuga: Gahnawiyogeh) is a state located in the South Central United States. Oklahoma is the 20th most extensive and the 28th most populous of the 50 United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people". It is also known informally by its nickname, The Sooner State, in reference to the non-Native settlers who staked their claims on the choicest pieces of land before the official opening date, and the Indian Appropriations Act of 1889, which opened the door for white settlement in America's Indian Territory. The name was settled upon statehood, Oklahoma Territory and Indian Territory were merged and Indian was dropped from the name. On November 16, 1907, Oklahoma became the 46th state to enter the union. Its residents are known as Oklahomans, or informally "Okies", and its capital and largest city is Oklahoma City.
