Input: Consider Input: Passage: The term "Enlightenment" emerged in English in the later part of the 19th century, with particular reference to French philosophy, as the equivalent of the French term 'Lumieres' (used first by Dubos in 1733 and already well established by 1751). From Immanuel Kant's 1784 essay "Beantwortung der Frage: Was ist Aufklarung?" ("Answering the Question: What is Enlightenment?") the German term became 'Aufklarung' (aufklaren = to illuminate; sich aufklaren = to clear up). However, scholars have never agreed on a definition of the Enlightenment, or on its chronological or geographical extent. Terms like "les Lumieres" (French), "illuminismo" (Italian), "ilustracion" (Spanish) and "Aufklarung" (German) referred to partly overlapping movements. Not until the late nineteenth century did English scholars agree they were talking about "the Enlightenment." Question: In what century did the term Enlightenment emerge in English?

Output: 19th

Input: Consider Input: Passage: Saint Valentine, a Roman Catholic Bishop or priest who was martyred in about 296 AD, seems to have had no known connection with romantic love, but the day of his martyrdom on the Roman Catholic calendar, Saint Valentine's Day (February 14), became, in the 14th century, an occasion for lovers to send messages to each other. In recent years the celebration of Saint Valentine' s day has spread beyond Christian countries to Japan and China and other parts of the world. The celebration of Saint Valentine's Day is forbidden or strongly condemned in many Islamic countries, including Saudi Arabia, Pakistan and Iran. In Saudi Arabia, in 2002 and 2011, religious police banned the sale of all Valentine's Day items, telling shop workers to remove any red items, as the day is considered a Christian holiday. Question: Who was Saint Valentine?
Output: a Roman Catholic Bishop or priest
